Explosives Atmospheres Regulations

Flammable substances used and stored in the laboratory are also subject to further risk assessment and control in UK law under the the Health and Safety at Work Act 1974, the Management of Health and Safety at Work Regulations 1999, the COSHH Regulations 2002, the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR), and the Regulatory Reform (Fire Safety) Order 2005. 

Directive 94/9/EC (ATEX 95) to approximate the laws of the Member States concerning equipment and protective systems intended for use in potentially explosive atmospheres governs requirements for products intended for the use in explosion risk areas. Directive 1999/92/EC (ATEX 137) on minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres regulates the minimum requirements for explosion protection at work places and for the safe use of products. The ATEX 95 therefore deals with the properties of the products to be used in explosion risk areas while ATEX 137 regulates their operation and other operational measures for explosion protection.

Requirements for their safe use and storage were contained in the Highly Flammable Liquids and Liquified Petroleum Gases Regulations 1972 which have been revoked by the Dangerous Substances and Explosive Atmospheres Regulations 2002. However, they did lay down sound precautions to be taken where highly flammable materials are used and potentially explosive atmospheres arise. Their contents are summarized below ... 

Newly introduced regulations The Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) deal with those substances -whether solids, dusts, liquids, vapours or gases - that, when present in the atmosphere, can ignite and cause injury or damage by explosion, fire or other event . The Regulations apply to all premises where such circumstances can occur but with certain listed exceptions.

In many cases, identifying a standard that can be adopted to measure workplace performance is straightforward. For example. Regulation 7 of the UK Dangerous Substances and Explosive Atmospheres Regulations 2002 requires certain places at workplaces to be classified in relation to the subject of the regulations as per Schedule 2, and to further divide the places classified as hazardous into different hazard zones. By referring... 

The use of electrical equipment in potentially flammable atmospheres should be avoided as far as possible. However, there will be many cases where electrical equipment must be used and, in these cases, the standards for the construction of the equipment should comply with the Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres Regulations (known as ATEX) and details on the classification or zoning of areas are published by the British Standards Institution and the Health and Safety Executive. 

Before electrical equipment is installed in any location where flammable dusts vapours or gases may be present, the area must be zoned in accordance with the Dangerous Substances and Explosive Atmospheres Regulations and records of the zoned areas must be marked on building drawings and revised when any zoned area is changed. The installation and maintenance of electrical equipment in potentially flammable atmospheres is a specialized task. It must only be undertaken by electricians or instrument mechanics who have an understanding of the techniques involved. 

The Dangerous Substances and Explosive Atmospheres Regulations apply to the use and storage of highly flammable substances. See Chapter 20 for a summary. Proper precautions include ...

Operators of Buncefield-type sites should review the classification of places within COMAH sites where explosive atmospheres may occur and their selection of equipment and protective systems (as required by the Dangerous Substances and Explosive Atmospheres Regulations 2002). This review should take into account the likelihood of undetected loss of containment and the possible extent of an explosive atmosphere following such an undetected loss of containment. Operators in the wider fuel and chemicals industries should also consider such a review, to take account of events at Buncefield. 

Recommendation 11 of the Buncefield MIIB report addresses the connected issue of the classification of places within CXDMAH sites where explosive atmospheres may occur and their selection of equipment and protective systems (as required by the Dangerous Substances and Explosive Atmospheres Regulations 2002).

The Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres Regulations 1996 were made by the Secretary of State for Trade and Industry, coming into force on 1 March 1996. They implement the provisions of Directive 94/9/EC, the so-called ATEX Directive, and they will be referred to here as the ATEX Regulations.
