These Regulations impose requirements for the purpose of eliminating or reducing risks to safety from fire, explosion or other events arising from the hazardous properties of a “dangerous substance” in connection with work. “Dangerous substance” is defined by regulation 2(1) to mean: a substance or preparation which meets the criteria in the Approved Guide to the Classification and Labelling of Dangerous Substances and Dangerous Preparations (5th Edition) (ISBN 0717623696) for classification as a substance or preparation which is explosive, oxidising, extremely flammable, highly flammable or flammable, whether or not that substance or preparation is classified under the Chemicals (Hazard Information and Packaging for Supply) Regulations 2002 (S.I. 2002/1689); a substance or preparation which because of its physico-chemical or chemical properties and the way it is used or is present at the workplace creates a risk, not being a substance or preparation falling within subparagraph (a) above; or any dust, whether in the form of solid particles or fibrous materials or otherwise, which can form an explosive mixture with air or an explosive atmosphere, not being a substance or preparation falling within subparagraphs (a) or (b) above. The Regulations implement, as regards Great Britain, Council Directive 98/24/EC (OJ No. L 131, 5.9.98, p.11) on the protection of the health and safety of workers from the risks related to chemical agents at work, so far as that Directive relates to safety, and Council Directive 99/92/EC (OJ No. L 23, 28.1.00, p.57) on minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres. Both of these Directives are individual Directives within the meaning of Article 16(1) of Council Directive 89/391/EC. The Regulations apply outside Great Britain in the same way that sections 1 to 59 and 80 to 82 of the Health and Safety at Work etc. Act 1974 apply by virtue of the Health and Safety at Work etc. Act 1974 (Application outside Great Britain) Order 2001 (regulation 12). Regulation 3 contains disapplications in respect of certain provisions of the Regulations. Regulations 3 to 14 and 17(1) to (3) do not apply to the normal ship-board activities of a ship’s crew (regulation 3(1)). The duties under the Regulations on an employer in relation to his employees extend to non-employees, with certain savings (regulation 4(1)). The duties under the Regulations also extend to self-employed persons (regulation 4(2)). An employer is required to carry out a suitable and sufficient assessment of the risks to his employees where a dangerous substance is or may be present at the workplace (regulation 5). “Risk” is defined as meaning “the likelihood of a person’s safety being affected by harmful physical effects being caused to him from fire, explosion or other events arising from the hazardous properties of a dangerous substance in connection with work and also the extent of that harm” (regulation 2(1)). Under regulation 3 of the Management of Health and Safety at Work Regulations 1999 (S.I. 1999/3242), an employer is already required to carry out a risk assessment. However, where a dangerous substance is or may be present at the workplace, he will now additionally need to assess the risks in the light of the requirements for the assessment under regulation 5 of these Regulations. Employers are required by these Regulations to eliminate or reduce risk so far as is reasonably practicable. Where risk is not eliminated, employers are required, so far as is reasonably practicable and consistent with the risk assessment, to apply measures to control risks and mitigate any detrimental effects (regulation 6(3)). Places at the workplace where explosive atmospheres may occur must be classified as hazardous or non-hazardous and hazardous places must be classified into zones on the basis of the frequency and duration of the occurrence of an explosive atmosphere (regulation 7(1) and Schedule 2). Equipment and protective systems in hazardous places must comply with the requirements of Schedule 3 (regulation 7(2)) and, where necessary, hazardous places must be marked with signs at their points of entry in accordance with Schedule 4 (regulation 7(3)). Employers are required to make arrangements for dealing with accidents, incidents and emergencies (regulation 8). Employers will also need to provide employees with precautionary information, instruction and training where a dangerous substance is present at the workplace (regulation 9). Containers and pipes used at work for dangerous substances must, where not already marked in accordance with the requirements of the legislation listed in Schedule 5, clearly identify their contents (regulation 10). Where two or more employers share a workplace where an explosive atmosphere may occur, the employer responsible for the workplace is to co-ordinate the implementation of the measures required by these Regulations (regulation 11). Regulations 13 and 14 allow for exemptions to be made from all or any of the requirements of these Regulations. Amendments are made to legislation which mainly concerns petroleum-spirit (regulation 15 and Schedule 6) and repeals and revocations of legislation are also made (regulation 16 and Schedule 7). Regulation 17 makes transitional provision. A copy of the Regulatory Impact Assessment prepared in respect of these Regulations can be obtained from the Health and Safety Executive, Economic and Statistical Advice Unit, Rose Court, 2 Southwark Bridge, London, SE1 9HS. A copy of the transposition notes in respect of the implementation of the two Directives referred to in paragraph 2 above can be obtained from the Health and Safety Executive’s International Branch at that Rose Court address. A copy of both documents has been placed in the library of each House of Parliament.

- Deaths of Ann Mawer and Sue Barker
Commons · Commons Chamber · 13 October 2008 · Shona McIsaac (Cleethorpes) (Lab)
I would like to extend my thanks to Mr. Speaker for selecting this topic for debate. The issues that I wish to bring to the attention of the House relate to the deaths of Ann Mawer and Sue Barker on Christmas eve in 2007. On that Christmas eve, 52-year-old Ann Mawer went to work at Fred's Taxis in the town of Immingham. Within about 15 minutes of arriving at work, there was a horrific explosion at the taxi office, which killed both Ann and her friend and co-worker, Sue Barker. So intense was the fire that resulted from the explosion that the women had to be identified through DNA. Sue…
- Deaths of Ann Mawer and Sue Barker
Commons · Commons Chamber · 13 October 2008 · The Parliamentary Under-Secretary of State for Work and Pensions (Jonathan Shaw)
I am sure that the whole House will commend my hon. Friend the Member for Cleethorpes (Shona McIsaac) for bringing this issue to its attention. Let me say how sorry I was to read about this incident, which resulted in the tragic deaths of Ann Mawer and Sue Barker. I am sure that all Members wish to express their deepest sympathy to the families of Ann and Sue. My hon. Friend referred to a meeting that she had with my ministerial colleague Lord McKenzie last Thursday. She was able to meet Ann Mawer’s sisters, Diana Ryan and Sylvia Layton, to hear their views on the incident and to discuss the…
- Mining: Health and Safety
Commons · Commons Chamber · 28 March 2017 · The Minister for Disabled People, Health and Work (Penny Mordaunt)
I thank the hon. Member for Livingston (Hannah Bardell) for securing this debate and for her passionate speech on an issue that is important to her and her constituents, as well as to the Government and the House. It gives us the opportunity to recognise the bravery of those workers at Burngrange mine, who, in providing for their families and securing resources for our country, made the ultimate sacrifice. The hon. Lady and her constituents have rightly marked the 70th anniversary of that appalling disaster with honour and dignity for the men who did not come home to their families on 10…
- Battery Energy Storage Sites: Safety Regulations
Commons · Commons Chamber · 5 June 2025 · Miatta Fahnbulleh
We recognise that there needs to be co-ordination, but first, let me take the framework that is in place. It is often claimed that there is no regulation in this sector because there is no specific law addressing battery safety. That is simply untrue. The safety and standards of batteries are assured throughout their life cycle. The Government are therefore confident that the safety risks posed by grid-scale batteries are relatively small and well managed. I will take each aspect of this matter in turn, beginning with the planning regime. Planning practice guidance encourages battery storage…
