  3. Care of Fire Extinguishers • Extinguishers must be regularly inspected and properly maintained. • Records keep inspections and maintenance on schedule. • Proper training required for inspection and maintenance. • Follow manufacturer’s recommendations.

  4. Inspection (1 of 2) • “Quick check” verifies availability for immediate use. • Check extinguishers on apparatus regularly. • Check tamper seals. • Weigh or “heft” to determine fullness. • Examine for obvious physical damage, corrosion, or leaks.

  5. Inspection (2 of 2) • Check pressure gauge. • Confirm proper identification by type and rating. • Shake dry chemicals to mix agent. • Check nozzle for damage or obstructions. • Take problem units out of service and replace with spares.

  6. Verification of Sufficient Extinguishing Agent • Stored-pressure extinguishers • Pressure gauge indicates if pressure is sufficient to expel entire agent. • Weight of unit indicates degree of fullness. • Intact tamper seal indicates fullness. • Cartridge-type extinguishers • Pressurized gas expelled only when cartridge punctured. • Un-punctured cartridge indicates full, proper charge.
