Fire Safety & Extinguishers — poster
A job-site fire doubles in size every 30–60 seconds. The difference between an incident report and a catastrophe is usually the first two minutes — and whether the nearest extinguisher works and someone knows how to use it.
Class A: wood, paper, trash. B: flammable liquids. C: electrical. Most site units are ABC. Check the gauge is in the green and the pin is sealed — monthly.
Pull the pin. Aim at the BASE of the fire. Squeeze the handle. Sweep side to side. Fight only small, contained fires with your back to an exit — anything bigger, evacuate and call 911.
Welding, cutting, grinding need a permit where required, a fire watch during and 30 minutes after, and combustibles cleared or covered within 35 ft.
Gas cans must be approved safety cans, stored away from ignition and exits. Propane cylinders upright and secured. Oily rags in closed metal containers — they self-ignite in piles.
