Explosive atmospheres can be formed in workplaces where dangerous substances (such as flammable and explosive materials) are manufactured, stored, moved, used or transported and where dusts are formed. An explosive atmosphere provides the potential for fire and explosion risk if not contained.

Flammables and explosives are classed as dangerous substances and are defined in the Dangerous Substances and Explosive Atmospheres Regulations 2002. These regulations require employers to protect employees and other workers from explosion associated with dangerous substances.

Employers’ Duties

Under the Dangerous Substances and Explosive Atmospheres Regulations 2002, employers must:

  • Ensure, so far as is reasonably practical, the health and safety at work of employees where explosive atmospheres may be present.
  • Carry out risk assessments on areas where explosive atmospheres could occur.
  • Eliminate or reduce the risks as far as is reasonably practicable by the introduction of control measures.
  • Classify areas where explosive atmospheres could occur
  • Mark points of entry.
  • Have procedures to collect, contain and remove any releases to a safe place, e.g using ventilation.
  • Have accident and emergency procedures and the required equipment to deal with an explosion incident.
  • Give employees suitable and sufficient information, instruction and training
  • Provide employees with suitable PPE, such as anti-static clothing.
  • Provide and ensure the proper use of equipment designed only for explosive atmospheres.

Under DSEAR, all measures to reduce explosion risk as far as practicable should have been in place no later than 30th June 2006.
