Recharged an ABC dry chemical fire extinguisher. I depressurized and disassembled the unit for cleaning and inspection, replacing the O-ring to ensure a proper seal. After refilling it with the correct agent, I reassembled and pressurized the unit to 195 psi using nitrogen. The hose and nozzle were inspected, and the extinguisher was tagged and ready for use.
