The technical specifications and safety protocols for a Carbon Dioxide (CO_2) Fire Extinguisher. Unlike dry powder variants, CO_2 acts as a "clean agent," extinguishing fires by displacing oxygen and cooling the fuel source without leaving residue.
Technical Applications
This unit is specifically rated for:
Class B: Flammable liquid fires (e.g., fuels, solvents).
Class C: Energized electrical equipment, where non-conductive agents are critical to prevent short-circuiting.
Operational Execution (PASS)
Deployment utilizes the PASS technique:
Pull: Extract the safety pin to enable the discharge lever.
Aim: Point the specialized discharge horn at the base of the fire.
Squeeze: Compress the lever to release the high-pressure gas.
Sweep: Move the horn evenly across the burning area to create an oxygen-depleted zone.
Critical Safety & Maintenance
Because CO_2 displaces breathable air, it carries a risk of asphyxiation; use in confined spaces without adequate ventilation is strictly prohibited. Maintenance focuses on weight loss monitoring (to detect slow leaks), inspecting the horn for structural cracks, and mandatory periodic pressure testing to ensure cylinder integrity under high-pressure storage conditions.
