The UK Office for Product Safety and Standards has issued a product recall for a pneumatic fan that has been incorrectly and unsafely sold as “explosion proof”.
The product may not be safe for use in potentially explosive or flammable atmospheres as there is no evidence it has been subject to the appropriate conformity assessment, the Trading Standards website says.
The ‘Powerstar Electricals BTF Series Explosion Proof Axial Flow Fan’ originates from China and was sold in the UK as suitable for use in hazardous areas and explosive atmosphere environments – the fan was available in 10″, 12″, 14″, 16″, 18″ and 20″ diameters. This product poses a “Serious” level of risk if used in potentially explosive or flammable atmospheres.
The fan has been assessed as presenting a serious risk of harm as it has the potential to act as an ignition source in a flammable atmosphere, which could lead to fire and explosion.
The range of fans have not been subject to an appropriate conformity assessment and do not bear any of the required markings from an ATEX Notified Body. The products do not meet the requirements of the Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres Regulations 2016 (ATEX), the Office for Product Safety and Standards website says.
The products have been withdrawn from sale and recalled from all known end-users and customers. Any customers who bought one of the products is being recommended to stop using these products in environments where a flammable or explosive atmosphere could form. The UK Office for Product Safety and Standards advise customers should contact their distributor to request redress.

UKEX Fan | Certified For Use In Hazardous Areas And Explosive Atmospheres
Republished with Kind Permission of Scott Harding from Woodcock & Wilson |
the UK leading specialist manufacturers of centrifugal, industrial, Axial and 3rd Party Certified Atex and IECEx fans.
A UKCA “Ex” fan is a fan that has been manufactured, and is correctly certified, for use in potentially explosive atmospheres within Great Britain, meeting all UKCA requirements. As a result of the UK leaving the European Union, the UK government issued a Statutory Instrument to product safety legislation meaning that the European Conformity “CE” marking will be phased out and replaced with a UKCA mark. Hazardous Area certification is also affected, meaning that the European term ATEX will no longer be recognised within Great Britain as it gets replaced with the agreed “UKEX” term.
The UK Government now recognises its own Designated Standards which will replace the EU’s Harmonised Standards that companies must use to ensure their products have conformity to GB Law.
Due to the high potential of a fan producing an ignition, the European Committee for Standardisation, back in 2007, published a standard for the Design of fans working in potentially explosive atmospheres. The current form of this standard is BS EN 14986:2017, which along with standards for non-electrical equipment for explosive atmospheres BS EN ISO 80079-36:2016 and BS EN ISO80079-37:2016 form the constructional requirements for any fan that is to meet the new UKEX certification, GB Law and therefore be suitable to be placed on the “UK market”.
The common Ex–in–hexagon symbol remains. This symbol alongside the UKCA mark will indicate that the fan complies with current UK legislation for hazardous area use. The correct marking is supported by UKEX documentation. Many manufacturers are using the UKCA, EU CE and the Ex logo where products meet both UKEX and ATEX requirements. From the beginning of January 2021, UKCA marked products along with UKEX goods for hazardous areas are being phased to replace CE and ATEX products. From the 1st January 2023 UKCA and UKEX requirements will only apply. CE and ATEX will no longer be accepted in Great Britain.
The World’s First ATEX & IECEX certified portable ventilation fans packed and ready to go from our warehouse with fast delivery. Contact Us for more information.
The requirements for self-certification and third party certification for Category 1, 2 and 3 hazardous area equipment remain unchanged across both UKEX and ATEX schemes. This contrasts with the IECEx scheme, where all equipment and the manufacturers design and production facilities must be independently assessed and approved. IECEx documentation can be used to form the technical assessments for both UKEX and ATEX certification. It is important to note that the documentation must be approved by, or submitted to, the appropriate accredited body. Only UK Approved Bodies can certificate for UKEX products. Only EU Notified Bodies can be used for ATEX certification which is valid in the European Economic Area (EEA) including Northern Ireland.

Guest Article by Sigma HSE
Back in the early noughties, Sigma-HSE’s Technical and Operations Director was working in the UK’s Health and Safety Executive as a Process Safety Specialist Inspector and was drafting guidance for the warehousing industry.
This cumulated with the publication of HSG71 Chemical Warehousing: The Storage of Packaged Dangerous Substances, which is still freely available from the HSE website.
This guidance was aimed at anyone with the responsibility of storing dangerous substances, regardless of facility size, and was applicable to transit/distribution warehouses, open-air compounds and locations generally associated with a chemical production site or end-user.
Prior to drafting this guidance, he also undertook a survey of the warehousing and logistics industry. Throughout this time, the examination and analysis of multiple returned survey forms raised one significant issue – only 30% of respondents stated that they stored chemicals or dangerous substances. A subsequent question on the survey provided the reason for this.
When asked what types of substances were stored, the replies stated pharmaceuticals, household and commercial consumer products, cosmetics, agrichemicals, food products etc. The wider logistics/warehousing industry clearly did not recognise that such products can indeed contain or be classified as dangerous substances.
When looking into the products stored by many warehouses and logistics companies across the UK, items such as aerosol cans of hairspray were seen as simply consumer personal products, despite containing extremely flammable LPG gas as an aerosol propellant. Indeed, the individual aerosol cans were correctly labelled as containing dangerous substances.
Warehousing & Logistics | DSEAR Regulations
You only need to travel along the UK’s motorway network to appreciate the growth in extremely large warehousing and logistics operations throughout the country (which continues to expand significantly), to understand how much potential there is for catastrophe if dangerous substances are not correctly understood, let alone stored or transported properly.
Introduction to DSEAR and Warehousing/Logistics
Although there is a guide for the safe storage of packaged dangerous goods, there is, in fact, a set of regulations with which the warehouse and logistics industry must comply. These regulations are the Dangerous Substances and Explosive Atmosphere Regulations (DSEAR) 2015.
DSEAR regulations deal with anything that can burst into flames or explode. This can include standardised materials that have already been classified as explosive or flammable i.e., liquids and gases, but will also include a range of combustible dust and powders. Many of these combustible substances are not classified as dangerous, but can still be ignited, thus resulting in fires or explosions, examples include foodstuffs (flour, sugars etc) and other organic solids.
Alongside materials, DSEAR regulations will apply to most activities that are undertaken throughout the warehousing and logistics industry (if materials are capable of combustion). The HSE state that a DSEAR may apply to any of the below activities:
As with all UK health and safety legislation, the regulations require you to undertake a risk assessment – this time focussed on those work activities handling substances capable of fire and explosion – and aim to prevent fires or explosions and to protect against the effects of fire and explosion.
Warehousing/Logistics Equipment
The primary focus of a DSEAR is to prevent fires and explosions. Essentially, this requires the prevention of a flammable atmosphere (a mixture of fuel and air capable of combustion). Where such flammable atmospheres are present on-site, then you must reduce the probability of potential ignition sources becoming realised.
As a result, mechanical or electrical equipment that has the potential to create an ignition source and is located within a flammable atmosphere generated under normal and expected malfunction operations needs to be special – this is often known as ATEX or Ex equipment.
Understanding Site Zones
To ensure that all equipment present in specific zones are suitable, the determination of where on your site potential flammable atmospheres and their extent/size is done by undertaking a Hazardous Area Classification (HAC) study. This, in effect, results in the creation of specifically classified zones.
Once these zones are known, any mechanical or electrical equipment, as well as fixtures, fittings and tools present, must be removed or replaced by special ATEX or EX equipment.
However, a challenge that many companies that Sigma-HSE have worked with, as stated in a previous blog on how to avoid over-zoning in hazardous areas, is that when they undertake risk assessments, like DSEAR, they;
‘Err on the side of safety. Whilst this should not be deemed to be an issue, it may be over cautious as it can result in large hazardous areas being designated and, in some cases, a higher than necessary classification of zoning (i.e. Zone 1/21 instead of Zone 2/22) or by blanket zoning an entire area.’
It must be noted that when hazardous zones are updated then a risk assessment must be undertaken by a competent person. Therefore, by incorrectly assigning an area the wrong zone, a large amount of financial expense in terms of purchasing and maintaining ATEX or EX certified equipment can be caused.
ATEX
Storage of Potentially Hazardous Materials
Obviously, with most warehousing operations, packaged substances are simply stored and then transported. These materials, when in their individual containers, ensures that the generation of flammable atmospheres is not possible. But, if these materials are to be spilt during stock movement, or if said containers leak, the possibility of generating a flammable atmosphere increases drastically.
There have been many serious fires caused by the spillage of flammable materials during the movements of materials within warehouses. One very large fire that resulted in the destruction of the whole warehousing structure occurred at a Boots site in Nottingham several years ago. In this incident, a forklift truck (not certified for use in flammable atmospheres) ran over a spilt aerosol can – the forklift truck was the source of ignition, and a small incipient fire very quickly grew to involve other combustible stock stored nearby.
Even if you are confident that you do not store or handle dangerous substances as stock, ancillary operations on site will utilise dangerous substances – and hence a DSEAR risk assessment including the Hazardous Area Classification is necessary. The presence of natural gas-powered boilers and heating systems; LPG or diesel-powered forklift trucks; even recharging electric forklift trucks (due to the generation of hydrogen gas) means that a DSEAR risk assessment is required.

Stock Insurance
The safe storage and supply of goods, alongside the safety of employees and your businesses infrastructure i.e., warehouses, machinery and transport equipment are of huge importance to the success of your business. So, by complying with DSEAR regulations, you’re preventing potential disasters that could severely impact your operations.
We touched upon the topic of insurance for the manufacturing industry a recent blog that you can read here. But a key finding was the fact that insurance companies are increasingly asking manufacturing businesses if they have undertaken a DSEAR assessment. As a result, we at Sigma-HSE have had multiple requests from these manufacturing businesses to undertake a DSEAR as requested by insurance companies.
As a result, warehousing and logistics businesses should start to think about the relationship between DSEAR and insurance. Although there isn’t a specific fire and explosion damage insurance policy that can be issued by insurance companies, there are other forms of insurance, that can pay to repair or replace items damaged due to a disaster caused by the above. So, by undertaking a DSEAR assessment, you can decrease insurance costs by confirming to insurance companies that you have applied a recognised safety regulation to your work environment.
Sigma-HSE are recognised experts in DSEAR and have undertaken DSEAR risk assessments throughout the processing industries for many years. Our consultancy team are on hand to discuss your requirements and will work with you to provide actionable safety solutions that are both cost and time effective.
