Fire prevention measures for coating production line

1 Electrical fire prevention measures

⑴ painting such as collision Ni is mainly to provide the electrical equipment in the workplace such as capacity function, which must be installed or repaired by a full-time electrician. In addition, when installing and overhauling electrical equipment, the spraying operation should be stopped, and inflammables such as paint and thinner should be moved to a safe place and tightly covered with non combustible materials to avoid fire caused by electrical sparks

⑵ the electrical equipment and lighting devices in the painting workshop must be explosion-proof. For example, the fan applies explosion-proof motor, and the fan impeller should be non-ferrous metal, so as to avoid sparks caused by ferrous metal collision. Explosion proof lamps must be used for lighting

⑶ all painting equipment, such as paint cabinet, induced draft fan, sprayer, conveyor chain, etc., should be installed with electrostatic grounding device, and its grounding resistance should not be greater than 10 ohms. All kinds of power transmission switches, distribution boards, circuit breakers, etc. are best installed outdoors and in safe places. (4) in electrostatic spray painting, in order to ensure fire safety, the voltage shall not be higher than 80000 volts, and the distance between the spray gun or spray plate and the steel barrel shall not be less than 250 mm, so as to avoid discharge caused by high voltage or too close spray distance, and fire caused by electric fire

2. Fire prevention measures for drying furnace in the first three quarters of 2013

⑴ it is strictly prohibited to use electric heating elements with exposed resistance wires, and use steam, hot air, far-infrared electric heating elements for drying. If the infrared lamp is used for drying, the infrared lamp should be fixed in the niche, and the outside should be protected by a glass cover. To prevent electric leakage and fire

⑵ when drying steel drums, the paint spraying room should be a little far away from the drying furnace. Don't rush into the drying furnace, so as to prevent the vapor of most of the solvent in the newly sprayed paint from spreading in the drying furnace, which will cause fire or explosion accidents in case of high temperature

⑶ when baking the steel barrel in the drying furnace, the ventilator must be started to prevent the solvent vapor from accumulating in the furnace and reaching the explosion limit concentration. If there is no ventilation equipment in the drying furnace, the drying time outside the furnace before entering the furnace can be extended to fully volatilize the solvent

⑷ for long automatic drying furnaces, ventilation pipes should be installed on the top, and explosion-proof doors should be installed at appropriate positions. In order to relieve pressure in case of accidents, it is also conducive to timely troubleshooting in the furnace

⑷ the oven temperature should be controlled not to be higher than the natural point of the solvent in the paint to prevent spontaneous combustion

3. Fire prevention measures for paint storage

⑴ paint and solvent should be stored in a dry, cool, ventilated, heat insulated warehouse without direct sunlight. The fire resistance rating of the warehouse shall be level I and level II, and shall not be mixed with ordinary materials

⑵ open flames and smoking are not allowed within 30 meters of the storage warehouse, and signs prohibiting fireworks should be posted

⑶ a wooden frame must be set up in the storage warehouse, and the paint bucket must be placed on the wooden frame to ensure stability. It is strictly forbidden to collide with the paint bucket upside down, causing sparks and causing fire

⑷ when the paint is stored in the warehouse, it should be handled with care. The manual stacking should not exceed 1.8m, and the mechanical stacking can be appropriately higher to avoid accidents caused by stacking

(5) combustible items such as cotton yarn and rags soaked in paint shall not be stacked in front of the paint warehouse, so as to avoid excessive backlog and heat or fire caused by electric fire and thunder

4. Fire fighting measures

⑴ the coating workshop or paint warehouse should be equipped with automatic fire extinguishing equipment, and the paint warehouse should be equipped with cooling equipment to ensure safety

⑵ paint workshop, paint mixing room, drying furnace, warehouse, etc. must be equipped with sufficient foam, dry powder and other fire extinguishers, dry sand and asbestos board. The fire extinguishers shall be distributed according to the principle of combining dispersion and concentration. Management personnel should understand the common sense of fire prevention and fire fighting, and be able to skillfully master the localization of innovative products. Fire extinguishers should be checked frequently and changed regularly

⑶ each coating worker should keep in mind the danger of flammable and explosive paint, have certain knowledge of fire prevention and fire fighting, and be skilled in using fire extinguishers and simple fire-fighting equipment. In case of fire, close the iron door of the adjacent workshop immediately, cut off the power supply of various equipment, and put out the fire immediately. If necessary, report to the relevant departments first and cooperate in extinguishing the fire
