Q: I was cleaning out my parents’ house the other day, and I found an fire extinguisher that looks like it’s about 20 years old. What’s the best way to get rid of it? Any advice you can give on how to dispose of a fire extinguisher?
A: You’re right to assume that an expired 20-year-old fire extinguisher is probably not safe or reliable to use anymore. Just as knowing how to use a fire extinguisher is important, it is almost equally important to know when it is time to dispose of an old fire extinguisher and replace it with a new one.
Fire extinguishers are filled with hazardous materials that are under high pressure. Thus, they should not be put in the regular trash. Read on to learn more about when old fire extinguishers should be replaced and how to dispose of a fire extinguisher properly and safely.
When should an old fire extinguisher be replaced?
Before disposing of old fire extinguishers, confirm that they actually need to be replaced. Fire extinguishers typically last between 5 and 15 years. In some cases, you may be able to find an expiration date or a date of manufacturing on the canister, which can help clue you in on the fire extinguisher’s age.
Even if you can’t find a date, there are other ways to assess whether you should replace your old model with a new fire extinguisher. If your fire extinguisher has any dents or bumps, is missing the pin or tamper seal, or otherwise looks to be in poor condition, it is time to promptly find a replacement.
If your old fire extinguisher has a pressure gauge, check to confirm that the needle is still pointing to the green section. When the needle is pointing to the red or white area on the gauge, it means it is either time to recharge or dispose of the fire extinguisher.
