According to the Code for Fire Protection Design of Buildings

The fire hazard level of production in China can be divided into light hazard level, medium hazard level, serious hazard level and warehouse hazard level.

Fire Hazard Rating - Light Hazard Class.

Building height. It is a hotel and office building of 24m and below; Buildings with closed systems only in the corridors, etc.

Fire Hazard Rating - Medium Hazard Class.

Level. l) High-rise civil buildings.

Fire Hazard Rating - Severe Hazard Class.

Level. Preparation and workshops for printing plants, alcohol products, flammable liquid products, etc.

Level. Flammable liquids.

Spray operation area, solid flammable materials.

Combustible aerosols.

Products, solvents, paints, asphalt products and other factories and production workshops, studios, stage "grape trellises" lower.

Fire Hazard Rating - Warehouse Hazard Class.

Level. food, tobacco and alcohol; Non-combustible and non-combustible items packed in wooden boxes and cartons, shelf areas of warehouse-type shopping malls, etc.

Level. Wood, paper, leather, grain and products, cotton, wool, linen, silk and chemical fiber and products, household appliances, cables, Group B plastics and rubber and their products, steel-plastic mixed material products, non-combustible materials packaged in various plastic bottles and boxes and warehouses for mixed storage of various items, etc.

Level. Group A Plastics and Rubber and Articles Thereof; asphalt products, etc.

China divides the fire hazard of production into five categories: A, B, C, D, and E.

They are Class A fire, Class B fire, Class C fire, Class D fire, Class E fire, and Class F fire.

Class A fire: refers to a fire of solid matter. Such as wood, hay, coal, cotton, wool, hemp, paper, plastic (there are ashes after burning) and other fires.

Category B fire: refers to a fire of liquids or meltable solid substances. Such as kerosene, diesel, **, methanol, ethanol, asphalt, paraffin and other fires.

Fires of coal, cotton, wool, hemp, paper, plastic (with ashes after burning), etc.

Category B fire: refers to a fire of liquids or meltable solid substances. Such as kerosene, diesel, **, methanol, ethanol, asphalt, paraffin and other fires.

Class C fire: refers to a gas fire. Such as gas, natural gas, methane, ethane, propane, hydrogen and other fires.

Category D fire: refers to a metal fire. Such as potassium, sodium, magnesium, titanium, zirconium, lithium, aluminum-magnesium alloy and other fires.

Class E fire: refers to a live fire. A fire in which an object burns with electricity.

Category F fire: refers to a fire of cooking objects (such as animal and vegetable fats) in cooking utensils.

Fire: Fire refers to a catastrophic burning phenomenon that is out of control in time or space. Among all kinds of disasters, fire is one of the main disasters that most frequently and universally threatens public safety and social development.

The ability of human beings to use and control fire is an important sign of the progress of civilization. Therefore, the history of human use of fire and the history of fighting fire go hand in hand, and people constantly summarize the laws of fire while using fire, so as to reduce fire and the harm it causes to human beings as much as possible. In the event of a fire, people need to escape safely and as quickly as possible.

According to the Code for Fire Protection Design of Buildings, how many categories does China divide the fire hazard of production?

Correct answer: Five categories.

Answer]: cAt present, there is no unified classification method for the fire hazard of raw liquid spike production plants and storage warehouses in the world. According to the current national standard "Code for Fire Protection Design of Buildings" (GB50016-2014), the fire hazard caves produced in China are divided into 5 categories.

Answer]: a, e

The ammonia compressor room, rosin refining plant, and Jingnai plant of coking plant are all Class B fire hazard plants.

The Code for Fire Protection Design of Buildings stipulates that the fire resistance level of buildings is divided into (Sun Ming) class.

a, one. b, ii.

c, three. d. Four brief notes (correct answers).
