OPERATION OF FIRE EXTINGUISHER
- Pull the safety pin
- Aim the nozzle at the base of the fire
- Squeeze the lever
- Sweep from side to side
Fire Extinguishers are designed to be a one-use product. Upon usage, fire extinguishers are to be recharged immediately at an Authorised recharging station. If you “test” a fire extinguisher by activating it, the powder that comes out of the extinguisher will prevent the valve from fully closing, causing the propellent to slowly leak out over a period of time.

The owner or occupant of a property in which extinguishers are located shall be responsible for such inspection, maintenance and recharging.
Reference: Singapore Standards 578: Section 10.1.2
Frequency of inspection
The extinguishers shall be inspected monthly by the building owner or occupant, or at more frequent intervals
