            product details

            1. Structure and purpose

            The MTT/24 cart-type carbon dioxide fire extinguisher is composed of steel cylinders, valves, injection systems, and cart walking systems. The high-pressure liquid carbon dioxide fire extinguishing agent in the cylinder is used to extinguish the fire. Technical performance meets the requirements of GB8109-2005.

            Carbon dioxide fire extinguishing agent is a common gas fire extinguishing agent. It has the advantages of cooling the burning material, isolating the air to prevent combustion, leaving no traces, not polluting the environment, non-conductive, easy to manufacture, and low in price. It is suitable for extinguishing flammable liquid fires in enclosed spaces, extinguishing fires of live equipment and fire extinguishing agents such as water, foam, dry powder, etc., which are susceptible to fouling objects. It is widely used in fire and extinguishing of power distribution rooms, ships, warehouses, vehicles, electronic instruments, valuable equipment, libraries, archives and other places of factories and enterprises.

            Note: Carbon dioxide fire extinguishing agent cannot extinguish fires of alkali metals such as sodium and potassium and hydride, nor can it extinguish fires of some compounds that contain oxygen sources, such as nitrocellulose.

            2. How to use

            1. When in use, unfold the hose, turn the valve counterclockwise to the top, take off the nozzle, about 5m away from the burning object, aim at the upper part of the flame and extinguish the fire from far to near.

            2. When extinguishing a fire, do not use it against the wind. When extinguishing an oil fire, do not directly impact the oil surface to avoid the spread of flame caused by oil splash.

            3. Extinguish the fire quickly, decisively, and prevent hands from freezing. After the fire is extinguished, the operator should leave quickly to prevent suffocation.

            4. When using it, keep it upright and never use it lying down or upside down.

            5. When the content of carbon dioxide in the air is high, it will cause breathing difficulties and even death. Pay attention to prevent poisoning when using it.

            6. When a carbon dioxide fire extinguisher is extinguishing an electrical fire, if the voltage exceeds 600V, remember to cut off the power before extinguishing the fire.
