Portable carbon dioxide extinguisher

1. Carry the extinguisher to a safe position and keep the cylinder upright.
2. Pull out the safety pin or remove the seal.
3. Hold the insulated handle or approved grip, not the discharge horn outlet.
4. Aim the horn or nozzle at the base of the flame.
5. Press the handle to discharge CO2 and sweep across the fire base.
6. Ventilate the area after discharge where it is safe to do so.

Portable CO2 extinguishers discharge carbon dioxide gas that leaves no residue. They are commonly selected for electrical panels, precision equipment, laboratories, offices and liquid fire hazards.

• CO2 is suitable for many Class B and energized electrical fire scenarios.
• The agent cools and displaces oxygen around the fire zone.
• Use in confined spaces requires caution because CO2 can reduce breathable oxygen.

The unit includes a high-pressure cylinder, valve assembly, safety device, siphon tube and discharge horn or nozzle. Opening the valve releases liquid CO2, which expands rapidly into cold gas and snow-like discharge.

• The horn and discharge area can become extremely cold.
• Cylinder weight is an important charge verification method.
• Do not tamper with the pressure vessel, safety membrane or valve.

Store the extinguisher upright in an accessible location away from high heat, impact and corrosive atmosphere.

• Check cylinder appearance, safety pin, seal, valve, horn and hose condition.
• Verify the gross weight according to the inspection plan.
• Remove from service if there is leakage, corrosion, impact damage or missing safety parts.

• Service must be completed by qualified pressure-vessel and fire-extinguisher maintenance personnel.
• Weigh the cylinder and compare against the nameplate or service record.
• Inspect the valve, safety membrane, horn, hose and cylinder thread condition.
• Hydrostatically test the cylinder according to pressure-vessel rules and local regulation.
• Replace safety membranes and seals during qualified service where required.
• Recharge only with approved CO2 agent and do not overfill.
