Fire extinguisher commissioning

Fire extinguishers do not come ready commissioned because they could be damaged, discharged or have lost pressure during delivery. Therefore, British Standard 5306-3 recommends that extinguishers are commissioned on-site by a competent person.

British Standards are recommendations, not legal requirements, however, the Regulatory Reform (Fire Safety) Order 2005 states that any equipment, such as fire extinguishers, 'should be subject to a suitable system of maintenance and be maintained in an efficient state, in efficient working order and in good repair.'

Commissioning a fire extinguisher

Before the fire extinguisher is ready to use it is essential to:

  • Attach the discharge nozzle if it is not already fitted.
  • Check the tamper device is intact.
  • Check the pressure gauge is in the green.
  • Check the extinguisher for corrosion or obvious damage.
  • Weigh the extinguisher and record on the maintenance label.

Only when a fire extinguisher has been properly commissioned to BS5306 standard can you use the certification document, as proof that you have fulfilled your responsibility in accordance with your fire risk assessment.
