Key Hazards
- Using foam extinguishers on the wrong type of fire
- Electrical shock if used on energized equipment
- Chemical exposure from foam concentrate or discharge
- Pressure release from damaged extinguishers
- Delayed evacuation from attempting to fight unsafe fires
- Slips from foam discharge on walking surfaces
2–3 Minute Talk Script
Foam fire extinguishers can be effective for certain fires, but they must be used only where appropriate and only when the fire is small enough to fight safely.
Workers should understand the extinguisher type and what fires it is designed for. Foam extinguishers are not the right choice for every fire.
Foam should not be used on energized electrical equipment unless the extinguisher is specifically rated and approved for that use. Electrical shock can be a serious hazard.
Workers should inspect extinguishers visually. The pressure gauge, pin, hose, nozzle, label, inspection tag, cylinder, and mounting location should be checked.
A worker should only attempt to use an extinguisher when trained, the fire is small, an exit is behind them, and emergency response has been activated according to procedure.
Foam discharge can create slippery surfaces. Workers should watch footing during and after use.
Chemical exposure should be considered. Foam concentrate or residue may irritate skin or eyes and may require cleanup according to procedure.
Safe foam extinguisher use depends on choosing the right extinguisher, knowing when not to fight the fire, keeping an exit path, and evacuating if the fire grows or conditions change.
Safety Reminders
- Know what fire class the extinguisher is for.
- Do not use foam on energized electrical equipment unless approved.
- Inspect extinguishers regularly.
- Use only if trained and the fire is small.
- Keep an exit path behind you.
- Watch for slippery foam residue.
- Evacuate if the fire grows or smoke increases.
Ask the Crew
- Is this extinguisher correct for the fire hazard?
- Is energized electrical equipment involved?
- Has the extinguisher been inspected?
- Is the fire small enough to fight safely?
- Is the exit path clear before using the extinguisher?
