2kg Fire Extinguisher

Fire extinguishers are widely deployed in learning and working environments, and are a kind of fire extinguishing equipment that ordinary people can use. Mastering the correct use of fire extinguishers can eliminate small fires in the initial stage, prevent the fire from turning into a wildfire, and avoid causing serious losses to people's lives and property.

The main component of the fire extinguishing agent of the water-based fire extinguisher is water, and its specific fire extinguishing efficiency is achieved by adding different additives. The main function of water-based fire extinguishers is to isolate and cool combustible materials.

Water-based fire extinguishers are divided into ordinary type, spray type and foam type. Ordinary water-based fire extinguishers are mainly used to put out general class A fires, spray type can better fight live item fires, foam type in addition to fighting common class A fires, especially suitable for extinguishing oil class B fires. Specifically, ordinary water-based fire extinguishers are mainly configured in places where general combustible solid substances are stored, such as warehouses of paper, wood and bamboo products, textiles, rubber and other materials, and can also be configured in stadiums, classrooms, offices and other places.

Foam type water-based fire extinguisher can not only be used to put out ordinary solid fires, because of its foam covering effect, but also can be used to put out most flammable liquid fires (except alcohol and oil pan fires), such as garage, power generation room, laboratory and other places. Because water can react violently with active metals such as potassium, calcium, sodium, and magnesium to produce combustible gases and heat, it cannot be used to fight active metals (also known as light metals) fires. Water-based fire extinguishers from the factory for at least three years, after every two years, must be sent to a qualified maintenance unit for hydraulic test inspection. Portable water-based fire extinguishers must be scrapped after 6 years. In addition, it is necessary to carry out daily inspections of water-based fire extinguishers, and it is found that insufficient pressure or rust must be sent to qualified units for maintenance and pressure in time.
