How often must school bus fire extinguishers be serviced?

School bus fire extinguishers must be serviced every 12 months to ensure they are functioning properly and ready for use in case of an emergency. Regular servicing allows for checks on the pressure, condition, and functionality of the extinguisher, which is crucial for safety on school buses. This annual maintenance is a standard requirement in order to comply with safety regulations and help prevent potential hazards. Having fire extinguishers maintained on this schedule ensures that bus drivers and occupants have reliable fire protection available whenever needed.
