- Powder fire extinguishers are suitable for use on class A, class B and class C fires but are used in a variety of ways depending on the type of fire they are being used on.
- Only tackle small fires with a fire extinguisher. If a fire has broken out, do not fight the fire but evacuate immediately and warn others about the fire, then call the fire and rescue service. Please note that powder from fire extinguishers spreads and can be inhaled. It can also reduce visibility. Therefore, only use with caution in enclosed spaces. If you tackle a fire, ensure you stay at a safe distance and follow the instructions below. 1. Pull the safety pin (Figure 3) , this will break the tamper seal. Squeeze the lever to start discharging the extinguisher. 2. Instructions for using fire extinguisher:
- Solid materials: Direct the nozzle at the base of the fire, moving through the burning area -
Spilled liquid: Aim the nozzle at the near edge of the fire and with a quick sweeping motion, direct the fire towards the far side until all the flames have been extinguished - Flowing liquid: Aim the nozzle at the base of the fire and sweep upward until all the fire has been extinguished
