Fire extinguishing devices are safety equipment used for the prevention and control of fires. Their main function is to quickly detect the fire source in the early stage of a fire and automatically or manually release the fire-extinguishing medium, thereby effectively suppressing or extinguishing the fire and reducing casualties and property losses. At the same time, it can also slow down the spread of fire and buy time for personnel evacuation and fire rescue. In some unattended or high-risk environments, fire extinguishing devices can provide all-weather protection and enhance the overall safety level.

The application scenarios of fire extinguishing devices are very extensive. In the industrial field, it is often used in factory production lines, electrical control cabinets, distribution rooms and mechanical equipment areas to prevent electrical fires and accidents caused by equipment overheating. In the energy and chemical industry, it is applicable to flammable and explosive environments such as oil depots, gas stations, and chemical plants. In the field of construction, public places such as shopping malls, hotels, hospitals and office buildings are generally equipped with automatic sprinkler or gas fire extinguishing systems. In addition, in places with a high concentration of electronic equipment such as data centers and communication rooms, gas fire extinguishing or aerosol fire extinguishing devices are often used to prevent water from damaging the equipment. In terms of transportation, fire extinguishing systems are also widely used in subways, airports and ships to ensure operational safety.
