Whether the pipe fire extinguisher has been used, starting from the date of the fire extinguisher's factory, when the service life of the fire extinguisher exceeds the specified period, it should be sent to a professional maintenance unit for inspection. If it is a water-based fire extinguisher, it needs to be scrapped after its service life exceeds 6 years. If the dry powder fire extinguisher has a service life of more than 10 years, it needs to be scrapped.
