China Classification and code commonly used fire-fighting equipment breakdown –
(1) fire fighting equipment in China commonly used classification and code for that?
Fire equipment in China commonly used classification is based on the name of the Chinese phonetic alphabet capital equipment, said, basically: Fire Pump B (pump), fire C (car), accessories and parts F (attached), rescue tools G (Engineering), Alarm Equipment J (police), interface K (I), fire extinguishers M (off), foam equipment P (foam), Water gun Q (gun), personal equipment, firemen R (person), fire hydrants S (bolt), fire ladder T (ladder), Extinguishing agents Y (medicine), automatic fire-fighting equipment Z (self) and other 14 categories.
(2) What is a fire extinguishing agent? A peace which exists in the form can be divided into several categories?
Can effectively destroy the burning conditions for the termination of the material referred to as burning fire extinguishing agent. By normal form exists, extinguishing agents can be divided into three categories, namely, the liquid fire extinguishing agent, Gas Fire Agents and solid extinguishing agent.
(3) What are the main liquid type extinguishing agents? What characteristics of each?
Liquid fire extinguishing agent mainly in the following three types: First, water and water Additive Apply mainly to fight Class A fires; second foam extinguishing agent, such fire extinguishing agent from chemical substances, hydrolysis of protein or surfactant and other additives in an aqueous solution to form the concentrated solution. It is through a dedicated device mixed with water, diluted and then mixed into numerous air bubbles, finally the form of fire-fighting foam.
(4) What are the main gas fire extinguishing agent types? What are the characteristics it? Gas fire extinguishing agents are two major types: One is not combustible gases, mainly carbon dioxide, nitrogen and other inert gases; second fire extinguishing agent, which by the low level of hydrocarbons such as methane, hydrogen molecules are halogen atoms such as fluorine, chlorine replaced by other product. Gas fire extinguishing agent is gaseous or liquid form storage, and fire as gases, they can be used for A, C class fires and live fire fighting equipment.
(5) Solid What are the main types of fire extinguishing agent? What characteristics of each?
Solid fire extinguishing agent in the standard state is solid, solid powders are a mixture of three types: first, Dry powder fire Agent, which is fine, dry powder and salt additives; second powder extinguishing agent, it is a powdered solid mixture over dry powder extinguishing agent powder, mainly used for fighting metal fires, is a specialized fire extinguishing agent; third smoke fire extinguishing agent, is a special fire extinguishing agent for fire heavy petroleum products.
(6) foam fire extinguishing agent which main scope? Its use and base materials which can be divided into several different categories?
Foam is the application of B class, A class of fire; not apply to live fire, and C, D type fires. Anti-foam fire extinguisher can put out dissolved water-soluble flammable, combustible liquid fire.
They can be divided into protein foam extinguishing agent Foam extinguishing agent; F protein foam extinguishing agent; aqueous film-forming foam extinguishing agent; high-expansion foam fire extinguishing agent; in the low-expansion foam fire extinguishing agent and multiple foam fire extinguishing agent.
(7) foam foaming method is divided according to what types?
Can be divided into two categories: one chemical foam fire extinguishing agent. Chemical foam interior aluminum sulfate (acid) and sodium bicarbonate (alkaline) two kinds of chemicals. Use, the chemical reaction caused by mixing two solutions, a bubble, and spray out under pressure for fire fighting. Contained in the gas bubble is generally carbon dioxide, known as both the total pharmaceutical chemical foam fire extinguishing agent, commonly known as acid fire extinguishers. The second is air extinguishers. Air foam filling the air foam fire extinguishing agent, and its excellent performance, long storage, high fire-fighting effectiveness, ease of use, is the chemical foam replacements.
