British Standard BS 5306-3 recommends a quick visual check every month. It takes a few minutes and doesn't need an engineer.

Check Each Extinguisher Is…

  • In its usual place, visible and not blocked.
  • Undamaged – no dents, rust or cracked hoses.
  • Not used – the safety pin and tamper seal are intact.
  • Showing a pressure gauge in the green, where it has one. Anywhere in the green is fine, including right on the line – temperature and atmospheric pressure can move the needle within the green range.
  • Clearly labelled, with the instructions facing outwards.

Enter a record of the check in your fire safety log book – the date and who did it. It's good evidence that your equipment is looked after.

If anything isn't right, take the extinguisher out of use and arrange a service or replacement.

Worth remembering… your fire risk assessment is what decides the equipment your premises need. This guide is general advice, not a substitute for it.
