Lithium Ion Storage and Charging cabinet – 90 Minute Fire Rated

Introducing the ION-LINE cabinet.

In Active Storage, lithium-ion batteries or battery packs are charged in a cabinet

(passive storage options are available)

When charging lithium ion batteries heat can be generated, if this heat output is too high, a fire may occur, for example if the lithium ion battery, charger or the cable is defective. Another major risk factor is thermal runawayof lithium-ion batteries

What if you could charge you batteries overnight in the safe knowledge they are protected by a 90minute fire rated cabinet that has smoke dectection and fire suppression built in.

Sentence after teenage apprentice overcome by chemicals
An alloy wheel refurbishment company has been sentenced after a 16-year-old apprentice worker was overcome by vapours from a chemical used in the stripping and cleaning of alloy wheels.

South Tyneside Magistrates’ Court heard how, on 12 December 2017, the employee of Wheelnut Ltd, entered an area of the company’s former premises in Swalwell, Newcastle upon Tyne, known as the “acid room”. The employee entered the room to retrieve alloy wheels from one of three barrels of a chemical substance containing Dichloromethane (DCM), Methanol and Hydrofluoric Acid used in the stripping process. He was subsequently found by a colleague slumped unconscious over a barrel.

An investigation by the Health and Safety Executive (HSE) found a risk assessment for the chemical wheel stripping process was not suitable or sufficient. Appropriate control measures should have included suitable exhaust ventilation in the room as well as respiratory protective equipment (RPE) for the employees. RPE was provided but it was not maintained in an efficient or effective state. Several parts of it were damaged and the air feed to it from the compressor was not filtered correctly. The investigation found that on this occasion, and previously, the employee was not wearing the RPE when he entered the room. Employees were not provided with suitable and sufficient information, instruction, and training with regards to the risks involved with using the chemicals, particularly the risks involved with using DCM.

Wheelnut Ltd of Whickham Bank, Swalwell, Newcastle upon pleaded guilty to breaching Section 2(1) of the Health and Safety at Work etc Act 1974. The company was fined £32,000 and ordered to pay full costs of £1718.50.

Speaking after the hearing, HSE inspector Joy Craighead said: “A young worker suffered a potentially serious injury. Breathing in DCM vapour can produce narcotic effects and, at high concentrations, unconsciousness and death. In this instance, the boy made a full recovery, but it could have easily resulted in his death.”

Commenting on the sentencing, Mike Brodie, Chemstore UK Managing Director said: “A storage arrangement with suitable extraction could have prevented this incident from happening. It is easy to underestimate the dangers of gases and vapours given off by chemicals because they can be odourless and vapourless but their effects can be devastating. Thankfully the apprentice in question made a full recovery but the incident is a reminder of the importance of storing hazardous substances correctly.”

Chemstore launches dedicated lithium-ion battery storage unit

Hazardous materials experts Chemstore have launched the Electrovault, a dedicated lithium-ion battery storage unit which can be tailored to an individual company’s needs.

Lithium-ion batteries are becoming increasingly popular, not least due to their use in electric vehicles, but there is still some confusion around the safest way to handle and store the technology.

Chemstore Managing Director Mike Brodie explains: “When it comes to lithium-ion battery storage a standard fire rated unit just won’t do yet we are finding many companies are unaware aware of this.

“For example one issue with lithium-ion batteries is the occurrence of thermal runaway; lithium-ion batteries have a narrow operating temperature range of between +15 and +45°C and if they exceed this limit a thermal runaway can occur where an increase in temperature changes the conditions in a way that causes a further increase in temperature. During a thermal runaway hydrogen fluoride HF, phosphorus pentafluoride (PF5) and phosphoryl fluoride (POF3) are released and studies have shown that using water as a fire suppressant may increase the formation of HF yet it’s not uncommon to find people storing lithium-ion batteries in units with water suppression systems.”

The Electrovault units are made to comply with RC61 guidelines for battery storage and can be tailored to suit your specification, whether that is:

  • Atex Rated Temperature control
  • Atex Rated Humidity Control
  • Atex Rated Gas detection systems
  • Fire Suppression Systems
  • Fire Rated  (including all Atex internal electrical components where  required)
  • Atex Lighting
  • Remote monitoring systems
  • FIFO control operations
  • LIFO control operations
  • Fire rated and segregated Quarantine areas
  • Restricted access control
  • Fully automated extraction systems

Hoverboard fire highlights dangers of lithium-ion batteries

A fire involving a popular electronic toy that put a number of children’s lives in danger has once again highlighted the dangers of lithium-ion batteries.

Shortly after 8pm on Monday 13 May a two-wheeled self-balancing electronic scooter, which are commonly known as hoverboards, exploded as it was being charged in the living room of the family’s home in Masefield Avenue.

Five children, aged between five and 10, were all asleep upstairs at the time.

Fortunately dad Robert Jones, 33, was awake and heard the hoverboard crackling and then saw it explode as he went into the living room to investigate.

The explosion activated the smoke alarms in the house and also alerted neighbours to the resulting fire.

The neighbours helped Robert wake up the children and carry them outside to safety.

No-one required medical attention but the fire caused significant damage to the living room, particularly the floor, walls and dining table.

Mum Claire Bevan, 30, said: “I was not at home at the time of the fire. I returned to find fire engines outside my home and that my sleeping children had been rescued by my partner Robert and neighbours.

“As a family we are aware of the possibility of hoverboards being charged causing a fire.

“We bought it from a reputable retailer and it was only left charging for 20 minutes.

“It just goes to show that frightening things you read about in the news can happen to you.

“The incident has left the whole family extremely shaken up and emotionally scarred.

“But the incident could have been far worse. We would never have left the hoverboard charging whilst we went to bed as we are aware of the dangers of doing that. I dread to think what the consequences could have been if we weren’t so knowledgeable about hoverboards and if the fire had started later at night.

“A charging hoverboard exploding like that could have killed another family, especially if they didn’t have smoke alarms.

An investigation has been carried out to establish the cause of the fire.

It is believed to have been caused by an electrical fault.

Widnes Fire Station Manager Stuart Devereux said: “Hoverboards have become extremely popular among children in recent years and there have been instances of the electric scooters hitting the headlines nationally and internationally for causing fires.

“There are three main causes of fires involving lithium ion batteries such as those used in hoverboards: the wrong charger being used, mechanical damage to the battery and a manufacturing defect.

“The lithium ion batteries used in hoverboards and other rechargeable items contain chemicals which are flammable.

In the event of a short circuit or an over-charge situation, they can heat up very quickly and burst into flames. The resulting fire, although relatively small, can be very intense and will produce dense smoke.”

Chemstore UK Managing Director Mike Brodie comments: “This incident goes to show yet again the unpredictable nature of lithium-ion batteries.

“Thankfully in this incident everyone was okay but it is a reminder of the potential devestation the technology can cause.

“Stories such as this one often drive an increase in enquires to Chemstore UK from companies concerned about the hazards associated with handling and storing lithium-ion batteries in their workplaces.

“Unfortunately we find that people are often using inadequate storage systems and have frequently had poor advice.

“As hazardous materials experts the Chemstore team has a wealth of experience in this area and we have even developed a dedicated storage solution, the Electrovault, designed specifically for the safe storage of lithium-ion batteries.”

Time to review your corrosive substance storage?

Chemstore, The Hazardous Materials Expert, is encouraging businesses large and small to review their corrosive storage requirements to ensure that they are keeping staff and members of the public safe and Chemstore has created a corrosives storage checklist to help.


The advice comes in light of an increasing number of public acid attacks which serve as a reminder of the devastating impact corrosive substances can have on human health.

Corrosives and their vapours can cause devastating damage to the skin, eyes, respiratory tract and digestive tract

As news reports have highlighted, corrosives and their vapours can cause devastating damage to the skin, eyes, respiratory tract and digestive tract and some corrosives can even eat through metal. Controlling access to these substances and storing them correctly in line with the Control of Substances Hazardous to Health Regulations (COSHH) 2002 is therefore essential but Chemstore finds it is a hazard that is easily overlooked, often because people don’t realise they are dealing with corrosive substances in the first place.

Mike Brodie, Chemstore UK managing director explains: “There is a common myth, as quoted by the HSE in its brief guide to COSHH, that companies don’t think they have any hazardous substances in their workplace when on closer inspection this is rarely the case.

People think that because they have been supplied with a substance it must be safe but this is simply not true

“There is an increasing drive to control public access to corrosives with retailers becoming more vigilant and measures such as banning cash purchases of acid being proposed but there has been less attention given to the fact that corrosive substances are still easily ac-cessible in many workplaces. Consequently we are urging companies to consider whether this is an area that needs review.”

Mike adds: “Another common myth is that people think that because they have been supplied with a substance it must be safe. This is simply not true yet this attitude means that many companies and consequently workers remain oblivious to the hazards of some of the substances they work with. At the most extreme we have seen hydrofluoric acid ,which is used for glass etching, metal cleaning and electronics manufacturing and can be fatal, stored in boxes on factory floors.”

The good news is that meeting your obligations in this area is often easier than people think. Chemstore has come up with a simple checklist which can be downloaded here to help businesses review their procedures and signpost them in the right direction for further information.

Safety Data Sheets


With over 20 years’ experience in the spill control and containment industry it never ceases to amaze me the amount of information that goes unnoticed. Safety data sheets are key to understanding/selecting the appropriate containment device.


Identify the Hazard


Section 1: of an SDS sheet is the identification of the substance. It provides the product name, product use, possible supplier details and manufacturer contact details. It should also contain emergency telephone numbers.

If you are unsure of anything with the product why not contact the manufacturer?


Section 2: covers the Hazard Identification.

Section 2.1 of the SDS sheet gives the classification of the substance or mixture.

Acetone as an example:

  • Classified as Flammable Liquid Category 2
  • Eye Irritant Category 2
  • Specific Target Organ Toxicity Single Exposure Category


2.2 Label element

Usually provided with the Global harmonised system (GHS) pictograms and in the case of Acetone:






Signal words, hazard classes and hazard statements such as:

  • H225: Highly Flammable liquid and vapour
  • H319: Causes serious eye irritation
  • H336: May cause drowsiness or dizziness

Precautionary statements:

  • P210: Keep away from heat/sparks/open flames/hot surfaces – No smoking
  • P305+351+338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do – continue rinsing


Within the first two sections we have identified the following: –

The liquid itself is highly flammable as is the vapour, it can cause serious eye irritation and may cause drowsiness or dizziness.

It should be kept away from not just flames but also heat and if it does enter the eye this should be rinsed with water continuously.



I now need to find out further information for example the process that a business uses this liquid for. If we continue with acetone and suggest that Company X uses acetone on rags for cleaning metal parts (a widespread use of acetone due to its degreasing properties).  I would ask the following questions and provide theoretical answers: –

  • Q.What size containers do we stock? A. 205L as its cheaper than 25L.
  • Q.How many 205L drums do we have onsite? A. 32.
  • Q.Where are they stored? A. In a shipping container in the yard near boundary fence.
  • Q.How do we transfer the drums into the container? A. Lower using forklift and manually handle from pallet into position.
  • Q.Are we storing or decanting? A. Both. We decant inside the store into smaller containers.
  • Q.What are the smaller containers? A. Fire rated, Justrite plunger cans.


If the company purchases 205L drums, they are usually delivered on a pallet and are handled multiple times before placing them by hand in their final storage location. This provides multiple opportunities for a spill to occur from over-handling. If the product is delivered securely on a pallet why not keep it on the pallet?


Containment and Storage


Section 7: When selecting the appropriate secondary containment device, section 7 of a Safety data sheet is a suitable place to start. The SDS sheet section 7.1 provides details on safe handling. When using Acetone as an example, precautions for safe handling include:

  • Use in a well ventilated area
  • Avoid inhaling vapour
  • Avoid contact with eyes, skin and clothing
  • Keep container tightly closed when not in use


Section 7.2 Provides conditions for safe storage, including any incompatibilities

  • Storage should be cool, well ventilated away from sources of ignition or heat
  • Prevent accumulation of static charge (see our static article)


Using the Company X example,  Acetone was stored and decanted/dispensed inside the shipping container, a cheap option but this commonly DOES NOT provide: –

  1. Good ventilation
  2. Good thermal protection (the shipping container will dramatically increase in temperature in summer months)
  3. Any protection against static charge the during dispensing process. (see our static article)
  4. Any secondary containment in the event of a spill


Section 9: of the SDS sheet provides physical and chemical properties of the product. In our example case Acetone, we now know is flammable. There is potential in the shipping container for raised temperatures so in the first instance I would investigate the flash point.


A common misunderstanding in my experience occurs between flash point and auto ignition: –

  • Flash point: “The temperature at which a particular organic compound gives off sufficient vapour to ignite in air”
  • Autoignition: “The autoignition temperature or kindling point of a substance is the lowest temperature at which it spontaneously ignites in normal atmosphere without an external source of ignition, such as a flame or spark”


Taking Acetone again as an example the Flashpoint and Autoignition temperatures are shown below:

  • Flashpoint 18 °C (closed cup)
  • Auto Ignition 465 °C


This information provides us with the knowledge to understand the risks involved with company X’s processes onsite. Storing 205L drums in a shipping container, in the summer could easily reach 40 °C. The drums of acetone will produce sufficient vapour that could then be ignited. The shipping container had little to no ventilation which contributes to a build-up of vapour particularly during dispensing/decanting.

The container was also placed near a boundary fence which goes directly against HS(G)51 guidance:

Table 1 Minimum separation distances:


  • One solution to the storage of Acetone at Company X is to provide a Firevault (Fire Rated Store) product that will protect the Acetone in the event of a fire. The unit should either be well ventilated naturally, or provide forced extraction that removes any build up of vapour from the store and away from any external hazard. The fire rated store could also be temperature controlled to make sure the product is kept below the Flashpoint preventing any flammable vapour from being created (any electrical components are EX-rated appropriately). The distances are based on what is considered to be good practice and have been widely accepted by industry. Although these distances may not provide complete protection to people or structures from a fire in the flammable liquid storage area, they should allow time during a developing fire for people to evacuate to a place of safety. If these distances cannot be met then typically a Fire Rated storage solution would be required.


    During a recent site visit I witnessed flammables stored next to a boundary fence in open racking.

    On the particular day in question a maintenance company were patching up potholes on the road next to the boundary fence. In doing so they used a gas canister and what can only be described as a flame thrower!

    What would happen if the vapour/boundary vegetation ignited on that day?

    Do you know what processes take place outside of your boundary?

    Think about smoking areas/policy, vandalism, even acts of God, for example lightening?

    Working Safely With Static

    by Mike Brodie

    What is static?

    Static electricity is, simply put, electricity that is stuck in a system with nowhere to go. Within a typical electrical circuit, the charge is contained within a closed loop and returns to the source after carrying out a specific task, powering your kettle or lighting your office for example.

    Static is different in that it can accumulate, often unnoticed, on plant, containers or even personnel. Due to lack of awareness or complacency in the workplace this build-up of energy can result in devastating, yet entirely avoidable accidents.

    The accumulation of electrostatic charge is caused by barriers between the static charge and its path to ‘true earth’. For example, electrostatic charge on steel drums can be prevented from being dissipated by the presence of protective coatings, rust, debris build up and even surface layers of the stored product. Static build up on personnel can be a result of wearing the wrong footwear, or the use of insulating gloves when handling product.

    Electrostatic sparking is caused by the rapid ionisation of the atmosphere between two objects at different electrical potential. When this voltage reaches a critical level, ionisation occurs in the form of a spark.

    If the atmosphere across the spark is between its upper and lower flammable limits, ignition of the atmosphere will occur, resulting in fire or explosion.


    The dangers of static.




    Possibly the most famous example of a disastrous electrostatic discharge is the Hindenburg ‘Airship’ explosion. According to a team of experts recently assigned to conclude what caused the vessel to explode on 6th May, 1937, determined the most likely cause was a build-up of electrostatic energy transferred to the airship by passing through highly charged thunderstorm clouds. The problem came about during landing, as the ground crew reached for the tie down ropes, a path was created for the charge to spark to ground as contact with the earth was made. This, in turn, ignited the Hydrogen gas used to fill the ship, resulting in the explosion that killed 36 passengers that day.





    Manoa Laboratory 2016

    A more recent example of disastrous electrostatic discharge includes an explosion in 2016 within the Manoa Laboratory at the University of Hawaii. Investigators noted that: –

    “…serious deficiencies in the institution’s approach to laboratory safety contributed to a lapse in proper risk assessment and lack of a culture of safety that ultimately led to the accident”.



    University of Hawaii

    A research fellow, visiting the Hawaii Natural Energy Institute biofuels research laboratory, was transferring a mix of flammable gases into a low pressure tank when the explosion occurred. The explosion seriously injured the lab technician, causing her to lose her arm. The University suffered an estimated $1,000,000 in damage to property and faces up to $115,500 in fines.

    Initial investigations put the blame on an incorrectly specified pressure gauge that was not suitable for use with flammable gases, however further studies into the event placed the blame on static discharge within the tank.

    Tank Before & After

    It appears the explosion could have been avoided however by carrying out a more detailed risk assessment of the process. In fact, although the experiment had been carried out 10 or 11 times previously it was noted that the investigators discovered a number of ‘near misses’ that should have caused the process to be shut down and investigated further.

    For example, a ‘cracking’ sound was reported during a similar experiment on another tank but the technician was advised to simply not use that equipment again. Equally of concern is that the technician had also reported receiving static shocks when touching the pressure vessel but was told not to worry about it.

    Where it is likely to occur in the workplace?


    It is always essential to consider static accumulation within workplace processes, but more so when these processes involve the creation of potentially explosive atmospheres. Such activities do not have to involve large quantities of flammables liquids or dusts. A few litres of flammable liquid, under the right circumstances can create the perfect conditions for an explosion throughout a workshop or laboratory. Common activities often include the collection of waste into larger drums/IBC’s for bulk disposal, or decanting of good product from larger drums into smaller containers for transfer into the workshop or laboratory.

    During both processes a release of flammable vapour is often unavoidable. A static discharge at this time can easily result in a devastating explosion or fire.

    Responsibility for these activities most likely rests with the operators, however due to the absence of a visible or tangible hazard, a lack of understanding or awareness can lead to complacency or honest mistakes and an electrostatic ignition.

    As an example, a calculation can be made to show the energy of an electrostatic charge typically found on a metal drum containing liquid.

    Example spark energy (joules) of a steel drum containing liquid = approx. 8.0 mJ


    Liquid / Gas Minimum Ignition Energy
    Methanol 0.14mJ
    MEK 0.53mJ
    Acetone 1.15mJ
    Toluene 0.24mJ

    It is clear to see that there is easily enough energy in commonly found activities to ignite a flammable atmosphere (within the explosive limits) of regularly used chemicals.




    There are many articles and best practice guides available in the market. In the UK, the DSEAR – Dangerous Substances and Explosive Atmospheres Regulations requires that a thorough risk assessment is carried out by a competent person.

    “…Where a dangerous substance is or is liable to be present at the workplace, the employer shall make a suitable and sufficient assessment of the risks to his employees which arise from that substance. … [including] … the likelihood that ignition sources, including electrostatic discharges, will be present and become active and effective”

    Regulation 5 – Risk Assessment.



    How we can solve the problem.


    Firstly, Chemstore can supply an on site assessment of your processes and facilities. If necessary, we can carry out a full DSEAR Risk Assessment for you to address any concerns you have regarding your process and to help put a plan in place for safe practices going forward.

    This can then be re-enforced with operator and staff training and awareness courses to improve knowledge of the risks and associated hazards.

    Chemstore’s Firevault and Safety Cabinet ranges can be supplied to ensure that all flammable liquids and gases are properly stored and that the environment for material transfer is made safe.

    We can also offer a range of grounding equipment, depending on the application, to ensure operators have the right equipment to carry out the tasks on site.

    Preferably, such equipment should not only monitor the presence of a connection to true earth (thus ensuring and static can safely drain away) but should also alert the operator if this state changes and the system becomes potentially dangerous.

    The operator can then shut down the process until the issue can be rectified.

    For example, when transferring liquids to/from 200L metal drums – we would typically recommend using ‘pressure clamps’ capable of penetrating any surface barriers like rust, protective coatings usually present in such scenarios.

    These clamps must be capable of achieving the (industrially accepted) contact resistance of 10 Ohms or less. Not only should they achieve this level of conductivity, but they should also be able to notify the operator that a good connection is ‘made’, or more importantly ‘not made’.

    Please enquire here for more information on this range of active products

    Although ‘active’ systems clearly offer a preferred level of risk mitigation, sites may (after careful risk assessment) elect to implement a more passive system that does not have ground status monitoring or feedback capability. In this case it is essential to understand the limitations of such a system, to ensure that a good connection has indeed been made and continues to be made during the process. The use of certified and approved Factory Mutual or ATEX equipment is essential to achieve this – which Chemstore can supply on request.


    The expert guide to safe storage of hazardous materials in laboratories.



    From speaking to our existing clients we repeatedly hear of uncertainty and lack of clear information and guidance on how to identify, quantify and alleviate the risks with hazardous materials in the workplace. Without accurate information we understand it makes it difficult to prepare for the risks and to be aware of what hazards are currently in your workplace.

    With that in mind, we are here to enable you with the right information and tools to eliminate the risk.

    The following guidance document will make it clear what steps you need to take to create a safe and compliant laboratory.

    The use of hazardous and volatile materials is part of daily processes in the majority of labs in universities, research facilities and production plants worldwide. It is currently not feasible to avoid the use of hazardous materials and what is often neglected is unsafe storage of these materials. Improper storage of these materials creates a prominent risk to human life, the environment and the business itself.



    We have broken down this process down into 4 areas:



    1. Risk Assessment

    2. Segregation of incompatible materials

    3. Storage of flammable materials

    4. Emergency preparedness and planning






    1.Risk Assessment


    Labs across all areas of industry that haven’t undergone an adequate hazardous material storage assessment exhibit common shortcomings. There is often no defined storage system which determines risks with each type of material present in the lab. Such facilities have the following unsafe storage systems and practices:


    –        Chemicals stored on lab worktops, benches and the floor

    –        Materials stored on structurally fragile shelves and above eye level.

    –        Not enough storage space for the hazardous material containers

    –        Unsafe containers used to store materials e.g. wooden cupboards

    –        Gas Cylinders located internally within a lab unnecessarily

    –        Flammables not stored in fire rated cabinets

    –        Excessive quantities of flammables stored internally within a lab

    –        Absence of inventory or stock management system for chemicals in the lab




    • Planning and forecasting for the exact activities and work that will be carried out in the lab should be documented in advance of the activities beginning. E.g. Distillation, HPLC, GC.
    • Identification of each material that will be used in each process is imperative before the work begins.
    • Quantification of the amount of each material you will require: no more or less than required should be present in the lab at one time.
    • One of the most important checks you need to make is that you have access to the SDS (Safety Data) sheets for each material. The SDS sheets will provide critical information for any material used in your process and the hazards associated.
    • It is a legal requirement under REACH regulations (EC) No. 1907/2006 that the manufacturer/supplier of the materials provide each SDS to you. For best practice you should consult the data sheets for each material before it is stocked in your laboratory.
    •  Once you have identified all of the above it will the enable you to begin assessing the risks that all operators in your lab will be exposed to and how to best mitigate those risks.






    2.Segregation of incompatible materials


    Our team often find when meeting our clients on site that one common practice is forgotten in laboratories. There is often one designated area/cabinet or container for all hazardous materials to be stored internally. Flammables, Oxidisers, Toxic and Corrosive liquids to name a few will be stored together.

    Incompatible chemicals need to be segregated according to the hazard classes of each material. This is as important as with an adequate segregation scheme adverse reactions between incompatible chemicals such as oxidisers and flammables can be avoided.



    –  When developing a segregation scheme for chemicals in the lab, your first point to check should be section 2 of the SDS sheets ‘ Hazards Identification ‘

    –  Ensure you have adequate space in your facility to allow for safe segregation and storage of each class of material.

    – Some materials will have more than one hazard associated. In this case you should always identify the address the most prominent risk first.

    e.g. Dimethlychlorosilane is both flammable and corrosive. In this case it would be best practice to address the flammable risk as a priority.sds















    3. Storage of flammable materials


    There is no doubt that the biggest area for concern our team always highlight with clients is the lack of awareness when storing flammable liquids internally. When carrying out a risk assessment of your laboratory and the hazardous liquids you are using and storing, you should immediately identify the flammable materials. Once you have documented an accurate list, you should then quantify in litres how much flammable materials you absolutely need to store internally in your laboratory.

    It is now a legal requirement that flammables must be stored in safety storage cabinets that satisfy the requirements of EN 14470-1.

    We would also like to reiterate that where possible the quantities of flammables be kept to a minimum.

    Please watch the following video that will certainly portray how the negligent handling and storage of flammable liquids could have serious consequences. Risk is always present when handling and storing flammable liquids, so be the one to act and not react after it’s too late!






    4.Emergency preparedness and planning.


    If you neglect the above safety procedures when handling and storing hazardous materials in your lab that you are exposing your employees, the public and the environment to untenable risks.

    • Insurance in many cases will become void if a fire or explosion occurs in your facility.
    • The company and its owners will be liable for any damage to persons, property and the environment.
    • Damage to your facility could cause long downtime and incalculable effects to the company’s reputation.


    In order to create the safest possible environment in your laboratory the final step you need to take is to create an emergency response plan in the event an accident occurs.This plan should be carefully written and shared with all employees. All tier 1 organisations are legally required produce an emergency response plan to the local    authorities as part of COMAH Regulations 2015.

    Emergency response plans need to be prepared addressing all four areas above in detail including accident scenarios with the hazardous materials present in you laboratory.  Once this emergency response plan has been drafted and approved by the certified body in your organisation, an open correspondence should be opened with the local emergency services and the Health & Safety authorities detailing this plan.


     From gathering extensive feedback from our valued client base and extensive research carried out throughout our 23 years in business, we are constantly striving to provide our clients with the tools and knowledge to eliminate the risks associated with hazardous material storage in industry.

    A key strength of Chemstore throughout its history has been anticipating and responding to the needs of our clients. Increasing the level of safety in your workplace is where our work begins. We will enable you to reduce risk, liability and downtime on your site. We will take your business beyond the legal requirements for health & safety and social responsibility in your organisation.

    Lessons learnt a year on following chemical spill at a St Andrews leisure centre.

    A leisure centre was evacuated in St Andrews in Scotland last August following a chemical spill. 19 people were taken to hospital following the spill. The casualties were brought to hospital due to breathing difficulties. Three fire engines and 15 ambulance service vehicles were called to East Sands leisure centre in St Andrews, Fife. The Guardian reported that “Victims said they had seen clouds of gas and smelt a strong odour that made them cough and their eyes sting. The leak was reported to be sodium hypochlorite, a chemical compound used to make bleach, though witnesses said they believed it to be chlorine.” Both chemicals pose a very real risk to human health with inhalation of enough quantities being linked with serious respiratory problems.  Almost a year has passed since this incident and the HSE have completed an investigation on the incident and have recently ordered for a number of safety improvements to be made.

    The incident at East Sands Leisure Centre in St Andrews left five children and 14 adults suffering breathing problems and requiring immediate medical treatment on August of last year. The HSE investigation has also highlighted several breaches of health and safety law, although thankfully steps of mitigation have now been taken to reduce the risk of such an incident happening again.

    Investigators from the HSE initially stated that the incident involved the uncontrolled release of the chemical sodium hypochlorite from the pool’s storage tank, but after further investigations the HSE have discovered more about how exactly this leak happened. According to the HSE report the design of the tank was “unsuitable” because it did not have “sufficient strength” for the loads which were applied to it. The HSE report also stated how the support structure for the tank was not suitable and as a result lead to a “more rapid failure.” The Courier reads that the HSE report described how “White crystalline deposits below the tank indicate that the tank was likely to have leaked for a long time prior to failure and this could have been identified during routine examination.” One other issue that was brought up by the HSE was that the bund which was surrounding the tank was in poor condition and was not capable of holding large quantities of chemicals.

    Following instruction from the HSE, swift action has been taken and Fife council have installed a different chlorination system at all of its swimming pools to ensure that there is no repeat of such an incident. Councillor Tim Brett was pleased to say that lessons have been learnt following this event. Scotsman news reported that Tim Brett said “this was a major incident which caused significant concern to all those involved in it at the time – fortunately no-one was seriously injured. I’m pleased to say the lessons learned both in managing the incident and on changing the chlorination system at the pool have been implemented.”

    Hazardous materials pose risks to even the most family friendly environments. Highly corrosive liquids used to treat and clean swimming pools such as sodium hypochlorite and other pool cleaning chemicals when used and stored in dangerous quantities can be lethal. It has to be the responsibility of both management and Health & Safety officials to instruct and ensure these chemicals are:


    • Stored in containers and tanks of compatible construction
    • Equipped with a secondary containment system or bunding which is resistant and certified to hold highly corrosive liquids.
    • Adequate PPE such as safety gloves, glasses and respiratory masks for operatives handling the hazardous materials
    • SOP (standard operating procedure) must be available for all operatives to read when using the chemicals
    • Safety signage must be positioned on cabinets, containers and tanks highlighting the hazards each chemicals poses.

    BREXIT – What it could mean for industry regulations & workplace health & safety.


    With so much uncertainty regarding the historic vote last Thursday 23/06/2016 when the people of the UK decided it was time to opt out of the European Union. A Prominent member since 1975 but much discontent was shared by the 17,410,742 (BBC 2016) people who decided it was time for some major change.


    In the aftermath of the EU referendum much has been speculated, there has been some contrasting projections made by experts as to how this decision will affect all areas of the economy, not just in the UK but across the globe.

    Here at Chemstore, we have tried to investigate what this historic decision will mean for industry, regulations relating to hazardous materials & workplace health & safety.


    Article 50


    Any Member State may decide to withdraw from the Union in accordance with its own constitutional requirements” (

    Article 50 of the Lisbon Treaty has been strongly debated over the last few days, which is the article prescribed as procedure for any member state who wants to leave the EU. Since this article has not been undertaken before, it will be a new process for both sides EU & UK.

    The article is a process prescribed over a two year period whereby the UK will negotiate terms with how it will leave the EU and the terms of trade between both the UK & EU going forward. It is still unclear as to how this will influence regulations relating to Health & Safety in the UK. Richard Jones, Head of Policy and Public Affairs with IOSH has stated “Post-Brexit, the UK has now less influence over EU law. Now we’re exiting, it’s vital the UK continues to apply our successful risk-based health & safety system which includes laws from EU directives because it’s been found to be fit for purpose by several independent reviews” ( June 2016)

    As article 50 is yet to be enacted by the UK as David Cameron has urged patience but reports today suggest this has aggravated other EU leaders as the European Commission chief  Jean-Claude Juncker has urged the UK to “clarify its position” as soon as possible ( 28/06/2016)


    Health & Safety Legislation – what will change?

    As the negotiations for the UK to leave the EU have yet to begin and as described above will take at least two years to be agreed and enacted, it seems at this point and time that very little will change in short term up to 2018 as a minimum. The main problem is that EU & UK regulations and legislation have become very much intertwined and it’s hard to see how much will change regarding how the UK governs Health & Safety as the current system is working.

    The Health & Safety Commission (HSC) which was founded upon the creation of the Health & Safety at Work Act 1974 “HASAWA” which precluded the UK’s entry into the EU which is the primary piece of UK health & safety legislation. It places the famous emphasis phrase to ensure “as far as reasonably practicable, the health and safety at work” of all employees in the workplace.

    Control of Substances Hazardous to Health Regulations (COSHH) was created and brought into law in 1988 in the UK but since has been revised to adhere to European Legislation. Listed below are a selection of EU directives have been included in the latest revision of the COSHH regulations 2002 which highlight how UK & EU legislation have merged:


    – 78/610/EEC protection to the health of workers exposed to vinyl chloride monomer

    – 89/677/EEC, art.1 (3) importation, supply and use of benzene

    – 90/394/EEC protection of workers from risks related to exposure to carcinogens at work


    The Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH)

    The REACH regulations came into force on the 01/06/2007 in all EU member states including the UK “replacing several Regulations and European directives with a single system. One of the main requirements of REACH is for importers or manufacturers of substances to register them with the central European Chemicals Agency. The aim of this is to ensure that human health and the environment is protected by ensuring that manufacturers and importers understand and manage the risks associated with chemicals. REACH also allows substances to move freely on the EU market as well as allowing for free competition and innovation in the European chemicals industry.” (

    What will be a major question regarding the UK’s exit from the EU is whether the REACH regulations will still allow chemical manufacturers in the UK to trade chemicals freely in the EU market. If not then one fears that the chemical manufacturing industry in the UK will be majorly affected by the loss of free trade.


    Another major European Regulation which is further example of combined laws the UK & EU currently share relating the hazardous materials is the (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures – The CLP Regulations. – The CLP regulations which replaced the CHIP labelling system to now adopt the Globally Harmonised System (GHS) on the labelling and classification of chemicals.

    CLP Labels 2016


    It is hard to see why the UK government – HSE would throw out these newly adapted regulations but only time will tell.

    What is certain is that BREXIT will cause a lot of uncertainty in industry and we can only hope at this stage that it will not have a negative effect on workplace health & safety going forward.
