num: Article 1
title: Object and scope
paragraphs: 1. This Directive, which is the 15th individual Directive within the meaning of Article 16(1) of Directive 89/391/EEC, lays down minimum requirements for the safety and health protection of workers potentially at risk from explosive atmospheres as defined in Article 2.
2. This Directive shall not apply to:
(a) areas used directly for and during the medical treatment of patients;
(b) the use of appliances burning gaseous fuels in accordance with Directive 90/396/EEC(7);

num: Article 2
title: Definition
paragraphs: For the purposes of this Directive, "explosive atmosphere" means a mixture with air, under atmospheric conditions, of flammable substances in the form of gases, vapours, mists or dusts in which, after ignition has occurred, combustion spreads to the entire unburned mixture.
num: Article 3
paragraphs: Prevention of and protection against explosions
With a view to preventing, within the meaning of Article 6(2) of Directive 89/391/EEC, and providing protection against explosions, the employer shall take technical and/or organisational measures appropriate to the nature of the operation, in order of priority and in accordance with the following basic principles:
- the prevention of the formation of explosive atmospheres, or where the nature of the activity does not allow that,
- the avoidance of the ignition of explosive atmospheres, and
- the mitigation of the detrimental effects of an explosion so as to ensure the health and safety of workers.
These measures shall where necessary be combined and/or supplemented with measures against the propagation of explosions and shall be reviewed regularly and, in any event, whenever significant changes occur.
num: Article 4
title: Assessment of explosion risks
paragraphs: 1. In carrying out the obligations laid down in Articles 6(3) and 9(1) of Directive 89/391/EEC the employer shall assess the specific risks arising from explosive atmospheres, taking account at least of:
- the likelihood that explosive atmospheres will occur and their persistence,
- the likelihood that ignition sources, including electrostatic discharges, will be present and become active and effective,
- the installations, substances used, processes, and their possible interactions,
- the scale of the anticipated effects.
Explosion risks shall be assessed overall.
2. Places which are or can be connected via openings to places in which explosive atmospheres may occur shall be taken into account in assessing explosion risks.
num: Article 5
title: General obligations
paragraphs: To ensure the safety and health of workers, and in accordance with the basic principles of risk assessment and those laid down in Article 3, the employer shall take the necessary measures so that:
- where explosive atmospheres may arise in such quantities as to endanger the health and safety of workers or others, the working environment is such that work can be performed safely,
- in working environments where explosive atmospheres may arise in such quantities as to endanger the safety and health of workers, appropriate supervision during the presence of workers is ensured in accordance with the risk assessment by the use of appropriate technical means.
num: Article 6
title: Duty of coordination
paragraphs: Where workers from several undertakings are present at the same workplace, each employer shall be responsible for all matters coming under his control.
Without prejudice to the individual responsibility of each employer as provided for in Directive 89/391/EEC, the employer responsible for the workplace in accordance with national law and/or practice shall coordinate the implementation of all the measures concerning workers' health and safety and shall state, in the explosion protection document referred to in Article 8, the aim of that coordination and the measures and procedures for implementing it.
num: Article 7
paragraphs: Places where explosive atmospheres may occur
1. The employer shall classify places where explosive atmospheres may occur into zones in accordance with Annex I.
2. The employer shall ensure that the minimum requirements laid down in Annex II are applied to places covered by paragraph 1.
3. Where necessary, places where explosive atmospheres may occur in such quantities as to endanger the health and safety of workers shall be marked with signs at their points of entry in accordance with Annex III.
num: Article 8
title: Explosion protection document
paragraphs: In carrying out the obligations laid down in Article 4, the employer shall ensure that a document, hereinafter referred to as the "explosion protection document", is drawn up and kept up to date.
The explosion protection document shall demonstrate in particular:
- that the explosion risks have been determined and assessed,
- that adequate measures will be taken to attain the aims of this Directive,
- those places which have been classified into zones in accordance with Annex I,
- those places where the minimum requirements set out in Annex II will apply,
- that the workplace and work equipment, including warning devices, are designed, operated and maintained with due regard for safety,
- that in accordance with Council Directive 89/655/EEC(10), arrangements have been made for the safe use of work equipment.
The explosion protection document shall be drawn up prior to the commencement of work and be revised when the workplace, work equipment or organisation of the work undergoes significant changes, extensions or conversions.
The employer may combine existing explosion risk assessments, documents or other equivalent reports produced under other Community acts.
num: Article 9
paragraphs: Special requirements for work equipment and workplaces
1. Work equipment for use in places where explosive atmospheres may occur which is already in use or is made available in the undertaking or establishment for the first time before 30 June 2003 shall comply from that date with the minimum requirements laid down in Annex II, Part A, if no other Community Directive is applicable or is so only partially.
2. Work equipment for use in places where explosive atmospheres may occur which is made available in the undertaking or establishment for the first time after 30 June 2003 shall comply with the minimum requirements laid down in Annex II, Parts A and B.
3. Workplaces which contain places where explosive atmospheres may occur and which are used for the first time after 30 June 2003 shall comply with minimum requirements set out in this Directive.
