The design of OEM Trolley-Type CO₂ Fire Extinguishers generally follows a standardized approach, taking into account the specific requirements for effectively suppressing Class B (flammable liquids) and Class C (electrical) fires. While the exact design can vary among manufacturers, here are some common features:
The main body of the extinguisher is a high-pressure cylinder typically made of steel or aluminum.
The cylinder is designed to withstand the pressure of the CO₂ gas.
A discharge nozzle or horn is attached to the cylinder. This directs the flow of CO₂ toward the base of the fire.
The trolley frame provides support and mobility. It often has wheels for easy movement, allowing the extinguisher to be transported to the location of the fire.
A handle and hose assembly are included to facilitate the controlled discharge of CO₂. The handle is typically used to activate the extinguisher.
A pressure gauge is usually mounted on the cylinder to indicate the pressure level of the CO₂ gas. This helps in ensuring that the extinguisher is ready for use.
The valve is a crucial component that controls the release of CO₂ from the cylinder. It is operated by the handle, and the design ensures a quick and efficient discharge.
A safety pin is often used to prevent accidental discharge. The pin needs to be removed before the extinguisher can be activated.
The extinguisher should have clear and visible labeling indicating the type of fire it is designed to suppress (Class B and Class C), its capacity, and any relevant safety instructions.
The exterior of the extinguisher may have a protective coating or finish to resist corrosion and environmental damage.
The OEM branding, model number, manufacturing date, and other relevant information provided by the original equipment manufacturer are typically displayed on the extinguisher.
