I. paper raw material warehouse fire risk
Paper raw material warehouse means the storage of rice, wheat straw, stalks of Reed, shu, flax, timber, etc. can be used to make paper raw material warehouse. Paper stock with flammability, a great fire danger, thus strengthening the fibrous raw material warehouse fire safety, fire prevention, reducing losses, is essential.
　　
Paper raw material warehouse fire risk:
　　
(A) paper stock with flammable, spontaneous
Various types of fibrous raw material are lighted only 150-200 ℃, cellulose, hemicellulose, waxy, pectin, fat, and other major components are flammable substances, the fire can burn. Straw, wheat straw, a Reed, cotton and other raw materials, water content is too high, it is composed of carbon, hydrogen, oxygen and other chemical composition, the role of the microorganism, the temperature to rise, reaching combustion conditions, causing spontaneous combustion, resulting in a fire.
　　
(Ii) in the yard and surrounding civil and industrial buildings, roads, flood, power overhead line spacing is not enough
Yard layout is reasonable, and close to life, production area and the railway, road, etc., external fire can cause stack is on fire.
　　
(Iii) the store does not meet the requirements
The stored goods does not perform the relevant technical requirements, items pile up excess, overtime, hyper-real, high water content, bad ventilation, formation of smoldering conditions cause a fire.
　　
(Iv) the power of fire mismanagement
1. in the paper raw material in or around erecting temporary electrical wiring and lighting, Cook-off combustibles, into the fire.
　　
2. electrical equipment, electrical wiring unreasonable or equipment, line failure, as well as lightning in itself cause a fire.
　　
3. in the area of use electric welding, gas welding, flame cutting or management staff smoking, children playing with fire.
　　
4, machinery and equipment due to friction, impact spark fire; to enter the area of automobile, tractor or motor boat from Mars or fibrous raw material contact temperature object and fire.
　　
5. farm bulk mismanaged, can not be timely clean. Admission for vehicle transmission shafts, etc. to be entangled in bulk, friction heat and ignition bulk or vehicle fuel tank fire.
　　
Second, paper raw material warehouse fire safety work

(A) the area of fire safety
1. site selection
Area would be on the edge near the town, there are water, residential area in the direction of all main and poop is not less than 2 m above the wall will isolate the area.
　　
2, fire separation
(1) in the area between certain safety distance. Reserves in 2 million tons of large raw material warehouse and production area, living area with a distance of at least 100 meters, 2 million tons of small and medium-sized raw materials warehouse and production area, living area of at least 50 m distance.
　　
(2) material yard and also railway centre line of the fire separation of at least 20 metres, and the distance from the main road at the venue for at least 10 m. Not suitable for drying raw materials inside the heap, the area in other articles do not stack.
　　
(3) raw farm stacking should heaps Spire put on top of the heap to knot the eaves of the roof should be boiled water slide. Stacking long edge should be parallel to the dominant wind direction in the local perennial. Stacking style, yard layout, stacking reserves, specifications and fire separation should be specified.
　　
(4) materials such as straw, wheat straw yards total reserves of not more than 2 million tons, exceeding who should set the partition. Area and district fire separation between the yard for a period of not less than 40 meters. Wood raw material yard each total reserves should not exceed 2.5 million cubic meters. Yard and yard fire separation between no less than 30 meters.
　　
(5) stacking arrangement by transportation lines, height 10 m, length of less than 50 meters. Stack and stack between 1.5-2 m wide channel to check. Every 2-4 stacking is divided into 1 group. Distance from wall is at least a stacked 5 m.
　　
(6) prevention of spontaneous combustion. Should be marked on the heap and stack files, number, quantity, water content, title, etc. Regular checks on the stack, measuring the humidity, temperature, moisture, leaving the vents in the stacking and cooling tunnel in case of spontaneous combustion.
　　
(Ii) strict control of power supply and fire
1. yard forbidden operations, needed fire jobs, there should be special guardianship and ready before the fire-fighting facilities. The job is finished, the complete elimination of fire. Into the yard of raw material should be carefully checked to prevent the belt into the fire. No smoking inside the heap and unrelated to the entry.
　　
2. steam locomotive, automobile and so need to wear fire Hat before entering the yard. Steam locomotive should close the GreyBox, air exchanger, not in the area of clean up the ashes. Transportation, lifting, and other mechanical equipment to be properly maintained to prevent friction, impact and generate sparks.
　　
3. reactor venue not to pull the wires to be set temporarily for overhead lines. You must set the overhead wire and stacking of distance not less than the rod high 1.5 times. Electrical equipment installation and maintenance required by the specialist is responsible for.
　　
4. yard in should use Searchlight, fire-proof dust-proof lamps for lighting. The prohibition of the use of mobile lighting, lamp, lamp not near the stacking
　　
5. pile of farm you want to make lightning, and periodically by hand on lightning detection; raw material yard not tied with wire to prevent lightning strikes.
　　
(Iii) improve the fire-no Shi
1. a yard of sufficient water to fire, in the absence of other fire sources, fire water tank should be able to meet the fire water 6 hours. Use natural water source for the fire with water, it is necessary to pay attention to the water in the dry season.
　　
2. should periodically fire water tank, pump room, underground fire hydrant, check, preventing the tank with water, lack of water and pipeline leakage, ensuring good water pump house motor and valve fittings to open properly.
　　
3. yard need set more than 6 metres wide withAnti Lane, and equipped with good fire-fighting equipment, such as fire pumps, fire extinguishers, fire engines, alarm devices, various fire equipment placement locations should be clearly marked, and should take the rain shower, Sun,
　　
4. strictly forbidden to occupy, bury, fire equipment, should be set in service management fire equipment.
