) ) ' 1. The structure and composition of the fire extinguisher
) ) The fire extinguisher is mainly composed of a cylinder, a bottle head valve, a spray hose (nozzle), etc. The fire extinguishing agent is sodium bicarbonate (type phosphoric acid Ammonium salt) fire extinguishing agent, the driving gas is nitrogen, and its working pressure at normal temperature is.
)
) ) ' 2. Main performance characteristics
) ) This series of fire extinguishers have the characteristics of high fire extinguishing efficiency and rapid fire extinguishing. The dry powder fire extinguishing agent inside has good electrical insulation and is not susceptible to moisture. Deterioration, easy storage and other advantages.
) ), the driving gas used is non-toxic, odorless, and will not harm the human body after injection.
)) The fire extinguisher bottle head valve is equipped with a pressure gauge, which can display its internal pressure and facilitate inspection and maintenance.
)
) ) ' 3. Scope of use
) ), suitable for extinguishing initial fires of flammable liquids and gases, and also for extinguishing fires in electrical equipment, of which type / can also be used Fight fires involving flammable solids. It is widely used in oil fields, oil depots, factories, shops, distribution rooms and other places. It is an essential fire-fighting equipment to prevent fires and protect people's lives and property.
) ), the operating temperature range is ℃ ~ + ℃.
)
) ) ' 4. Maintenance
) ) The storage environment temperature is ℃ ~ + ℃ and shall not be exposed to the scorching sun, close to fire sources, or subject to severe vibration.
)) Fire extinguishers should be placed securely and the storage location should be ventilated and dry.
)), always check whether the safety pin and lead seal are intact, whether the pressure value meets the requirements, and whether the parts are loose, deformed, rusted or damaged.
), fire extinguishers should be regularly inspected one year after expiration, check whether the bottle head valve, nozzle, etc. are damaged, check whether the cylinder is corroded, and conduct a hydraulic pressure test. Those that fail should be scrapped. .
)) Fire extinguishers should be repaired or refilled by a qualified professional fire maintenance department. Users are not allowed to disassemble or repair without authorization.
