Hazards
- Contents are under pressure and may explode when combined with other materials.
-
Very old fire extinguishers may contain carbon tetrachloride, a known carcinogen.
Handling
- Two most common types include "dry chemical" (sodium bicarbonate or monoammonium phosphate) and carbon dioxide (CO2) both of which are not hazardous.
-
To empty contents, discharge outside, away from children or pets. Monoammonium phosphate is an irritant
to eyes and the respiratory tract. Wear goggles and particulate mask when discharging extinguisher.
Management Options
- Dry chemical extinguishers
- May be discharged in an area where an acidic fertilizer would be used such as around evergreens. Do not use on lawns.
- When relieving the pressure (emptying) the container for disposal, review manufacturers instructions, or, if unavailable, use the PASS technique
- Pull the pin: this unlocks the operating lever and allows you to discharge the extinguisher. Some extinguishers may have other seals or tamper indicators.
- Aim low: Point the extinguisher nozzle (or hose) at the base of the item.
- Squeeze the lever above the handle: this discharges the extinguishing agent. Releasing the lever will stop the discharge. (Some extinguishers have a button instead of a lever.)
- Sweep from side to side.
-
After pressure has been relieved (when nothing else comes out) remove the head from the container
and place it with scrap metal or in the trash.
-
Carbon dioxide extinguishers
- These extinguishers are refillable and should be refilled after each use. Check Yellow Pages under Fire Extinguishers Recharging.
- If the extinguisher becomes defective, drill holes in the cylinder after pressure has been relieved and then place in the trash.
-
Ask fire equipment companies in your area if they will accept used extinguishers (listed in the Yellow Pages).
- Very old fire extinguishers
- Consult fire department.
-
Take to HHW collection or commercial hazardous waste facility.
