I. Risks of Expired Fire Extinguishers
1.The fire extinguishing failed
Dry powder fire extinguisher: When dry powder clumps, it cannot be sprayed out or the spraying force is insufficient to cover the fire source.
Water-based/foam fire extinguishers: The agent stratifies or deteriorates, losing its fire-extinguishing effect.
Carbon dioxide fire extinguisher: Pressure leakage, insufficient remaining dose, making it difficult to suppress the fire.
2. Safety hazards
Explosion risk: Rusting of the tank or abnormal pressure (such as the pointer entering the red zone) may cause a burst.
Secondary injury: The splashing of expired chemicals may cause chemical burns or environmental pollution.
3. Legal risks
Fire extinguishers in shops and public places that have expired and not been replaced may violate fire safety regulations and face penalties.
Ii. Correct Disposal Methods for Expired Fire Extinguishers
1. Do not handle by yourself: Do not attempt to disassemble, impact or burn to avoid explosion.
2. Professional recycling: Contact fire-fighting equipment companies, community fire stations or environmental protection departments, and entrust qualified institutions for recycling.
3. Replace with new fire extinguishers: Purchase compliant products based on the fire risk of the premises and conduct regular maintenance and inspection.
