(Continued from the previous period)
(3) The painting construction site prohibits smoking and prohibits the carrying of ignitants such as lighters and matches.
(4) When the painting shop needs to check for fire and welding, it must first go through the fire approval procedure, and after the approval, stop the painting operation. Before the fire, the paint scale and various flammable substances shall be cleaned within 30 meters of the work site. The paint bucket and the paint tank should be covered and sealed. The concentration of organic solvent vapor in the air must not exceed 1/3 of the lower explosion limit. Fire caused by fire.
(5) The spraying workshop must be equipped with strong ventilation equipment, and the natural ventilation conditions are better. In addition to local ventilation, paint booths, spray booths, and drying rooms should also measure the concentration of mixed gas at any time to prevent reaching dangerous limits. If there is a risk of fire, immediately switch off ventilation.
(6) In addition to the materials directly needed for production, the paint shop must not store a large amount of flammable and flammable materials to avoid fire.
(7) Doors and windows of paint shop, paint booth, drying oven, etc. shall all be opened outward.
2. Electrical fire prevention measures (1) The electrical equipment in the painting work site must be installed or repaired by a full-time electrician. In addition, when installing and repairing electrical equipment, the spraying operation should be stopped, flammable materials such as paint and thinners should be moved to a safe place, and be covered with non-combustible materials to prevent electrical sparks from causing fire.
(2) The electrical equipment and lighting fixtures in the painting shop must be explosion-proof. For example, explosion-proof motors for ventilators are used. Fan impellers should be non-ferrous metal to prevent sparks from flaming metal causing fire. Lighting must use explosion-proof lamps.
(3) All electrostatic spraying devices, such as spray booths, induced draft fans, sprayers, conveyor chains, etc., shall be equipped with electrostatic grounding devices. The grounding resistance shall not be greater than 10 ohms. All kinds of power-transmitting knives, switchboards, circuit breakers, etc. are best installed outdoors and in safe locations. (4) In electrostatic painting, in order to ensure fire safety, the voltage shall not be more than 80,000 volts, and the distance between the spray gun or spray disc and the steel drum shall not be less than 250 millimeters, so as to avoid excessive discharge caused by high voltage or too close spray distance. .
3. Drying furnace fire prevention measures (1) It is forbidden to use electric heating elements with exposed resistance wires, and apply steam, hot air, far-infrared heating elements, etc. for drying. If the infrared lamp is used for drying, the infrared lamp should be fixed in the alcove and a glass cover should be added outside. To prevent leakage and cause fire. (2) When the steel drum is being dried, the spray booth should be farther away from the drying oven. Do not rush to enter the drying oven to prevent the vapor of most of the solvent in the freshly sprayed paint from spreading in the drying oven. Or explosion accident.
(3) When the steel drum is baked in the drying oven, the fan must be started so that the solvent vapor does not accumulate in the furnace and reaches the explosive limit concentration. If the drying oven does not have ventilating equipment, it can extend the outside of the furnace before entering the furnace to allow the solvent to fully evaporate.
(4) Longer automatic drying furnaces shall be equipped with ventilation ducts on the top and explosion-proof doors in place. To relieve the pressure in the event of an accident, but also conducive to the timely removal of furnace failures.
(5) The temperature of the oven should not be controlled higher than the natural point of the solvent in the paint to prevent spontaneous combustion.
4. Paint storage and fire prevention measures (1) Paints and solvents should be stored in dry, cool, ventilated, heat-insulated, and direct sunlight-free warehouses. The fire resistance rating of the warehouse should be one or two and must not be mixed with ordinary materials.
(2) The open fire must not be used within 30 meters of the warehouse, and smoking must not be allowed. A sign of “no smoking†should be posted.
(3) A wooden rack must be set up in the storage warehouse. Paint buckets should be placed on wooden racks to ensure stability. It is forbidden that paint buckets will collide and collide, resulting in Mars causing fire.
(4) When the paint is put into the storage, it should be lightly lifted, and the manual stacking should not exceed 1.8 meters. The mechanical stacking can be appropriately higher to avoid accidents.
(5) In front of the paint warehouse door, combustible items such as cotton yarn and rags soaked with paint shall not be piled up to avoid heat buildup or heat or fire or thunderstorm causing fire.
5. Fire-fighting measures (1) Automatic fire-extinguishing and fire-extinguishing equipment shall be installed in the painting shop or paint warehouse. The paint library shall be equipped with cooling equipment to ensure safety. (2) A sufficient amount of foam, dry powder and other fire extinguishers, dry sand and asbestos boards must be installed in the paint shop, paint booth, drying oven, and warehouse. Fire extinguishers should be based on the principles of decentralization and concentration. Managers should understand common knowledge of fire prevention, knowledge of fire fighting, and be able to master fire extinguishers. Fire extinguishers should be checked frequently and regularly changed.
(3) Each painting construction personnel should keep in mind the danger of paint being flammable and explosive, and have certain knowledge of fire prevention and fire extinguishing. They will be skillful in using fire extinguishers and simple fire fighting equipment. In the event of a fire, immediately close the iron gates of the adjacent workshops and cut off the power of various devices and immediately extinguish the fire. When necessary, it should first report to the relevant departments to fight the fire. (End of the article)
