Fire Extinguishers require regular service and maintenance. It is one of those things that when you really need an extinguisher, you don’t want to discover it doesn’t work! Interestingly the only fire extinguisher with the horn (sorry I couldn’t resist) is CO₂ Carbon Dioxide; every other type of extinguisher has a hose …
Carbon Dioxide Fire Extinguishers, When Not To Touch The Horn
So what makes CO₂ so special and why does it have the horn in the first place? The extinguisher contains liquid Carbon Dioxide which when released, neutralises oxygen, effectively starving the fire.
“Most modern CO₂ fire extinguishers have a frost free horn!”
This is essential to prevent a very painful frozen hand. Just in case yours doesn’t have a frost free horn it is advisable not to hold the horn when discharging the CO₂ extinguisher.
The CO₂ extinguisher carries a black label and can be used for flammable liquids and live electrical equipment. This must not be used on chip fat fires. See our Fire Extinguisher Guidefor more details.
When your annual service comes around, an authorised technician will always remove the horn from the CO₂ extinguisher. Once removed, the contractor will carry out a number of specific inspections which includes weighing the unit and its contents to make sure no leakage has occurred. The horn must be removed to gain an accurate weight.
The service weight is then recorded on the maintenance label and will provide you with a visual note of when the extinguisher was last serviced.
“When was the last time your horn was off?”
