You can use IG541 or an aerosol for gas fire extinguishing. It is recommended that the specific design of gas fire extinguishing be carried out by a professional fire protection manufacturer.
Fire suppression systems are divided into two categories. The first is that multiple fire extinguishers are interconnected via connectors to form an overall fire extinguishing system. Second, a single fire extinguishing device constitutes a fire extinguishing system in itself.
1. Multiple fire extinguishers are interconnected via connectors to form an integrated fire extinguisher.
Refers to a group consisting of several fire extinguisher devices (devices), which are connected to each other via connectors according to predefined rules to form a whole. Depending on the set start mode (temperature detection, smoke detection, etc.), the fire extinguishers (devices) of the ssystem are started individually, several times or simultaneously to obtain a fire extinguishing system which cannot be completed by a single extinguisher (device) alone.
2. A single fire extinguishing device itself is a fire extinguishing system.
The various components of the fire extinguishing system are integrated with each other, interconnected and restricted to each other to form a relatively stable organization and structure, achieving fire-fighting effects. fire extinguishing that ordinary fire extinguishers cannot achieve. Generally, this type of fire extinguishing system is large, has many components, contains a large quantity of extinguishers, has many powder outlets, and has diversified directions.
The fire extinguishing system suitable for the petrochemical, transport, electric power and power generator rooms sectorsdiesel engines, fuel boilers, etc. in the industrial field is ()
Answer: D
Substances which are not suitable for use by water spray fire extinguishing systems:
1. Peroxide
Peroxide refers to potassium peroxide, sodium peroxide and barium peroxide, magnesium peroxide, etc. This type of substance will undergo a violent decomposition reaction upon contact with water, releasing heat of reaction and generating oxygen. When it comes into contact with certain organic materials, flammable substances, combustible substances, light metals and their salt compounds, it can. cause a violent decomposition reaction. Due to the reaction, excessive speed may cause explosion or combustion.
2. Substances that burn when exposed to water
Substances that burn oil and water include metallic potassium, sometal diium, calcium carbide, aluminum carbide, sodium carbide, potassium carbide, etc. This type of substance can decompose water when it comes into contact with water, take away the oxygen present in the water, combine with it, release heat and produce flammable gases, causing burning consequences or explosion.
Answer: D
The water spray fire extinguishing system requires higher water pressure and larger water volume than the water spray system. automatic sprinklers, it is therefore subject to certain restrictions of use. This type of system is generally suitable for industrial applications in the petrochemical, transportation and energy sectors. In recent years, many industries in China have gradually expanded the scope of use of water spray systems, such as diesel engine generator rooms and fuel-fired boiler rooms.ible in high-rise buildings.
