Recently, a fire broke out in a furniture factory in Huangpi Town, Suzhou City. There was a fire on the north side of the plant, and rescuers climbed the wall through the rescue ladder to rescue. However, the raging fire quickly spread and slammed into the roof of the factory to help with smoke and explosions. The warehouse door was opened and the roof of the factory was completely collapsed.
Since the wood is used to produce furniture, it burns more and more. The rescue team transferred five sets of high-pressure water guns. After nearly 10 hours of fighting, the fire was finally controlled.
After a preliminary investigation, it was not excluded that it was a foreign fire that ignited the fire.
In order to confirm how big the wood chips hit the power of the fire, the fire shovel conducted an experiment. Let's take a look.
Fire test
The fire shovel placed some wood chips in the device, then ignited the candle, then placed the ignited candle in the device and turned the blower on. As a result...
Furniture factory fire prevention work can not be ignored
The main source of fire in furniture factories: dust, sawdust, wood, etc. are flammable materials, often the source of fire broke out. The investigation of fire hazards in furniture factories mainly starts from these aspects.
Typical equipment for generating igniting materials are planers, grinders, woodworking band saws, milling machines, fans for dust collectors, and the like. These mechanical devices are often high-powered electrical appliances. When sawing, planing, and drilling in high-speed rotation, the fire is bred in friction.
Hidden Trouble Investigation: Mechanical Equipment and Open Flame
1. "Dark heat body" such as machine parts. High-speed friction and continuous oscillation will accelerate the aging of mechanical equipment parts, and become a "dark heat body" containing huge heat energy when falling off. They continue to release energy for hours, often igniting shavings or sawdust during workers' off hours.
2. Dust collector pipes and cloth bags. The pipes and dust collecting bags of the dust removal system are the main places for dust accumulation. The dust collector fan that runs at high speed causes the dust particles, dust and cloth bag to generate heat during friction. Because the dust bag and the pipe are relatively closed, the dust is heated and ignited, and the explosion is often induced, causing the fire to spread rapidly.
3. Drying room and its boiler. Wood drying rooms and boilers are high-risk places for fires in mahogany furniture factories. Incorrect operation methods lead to excessive pressure in the drying room and high temperature. The lightness increases the scrap rate of the wood, and the damage is large, causing fire and heavy losses.
4. Mars produced by the grinding wheel. Grinding machines for saw blades will produce Mars in high-speed collisions between metal and grinding wheels. Although the energy of a single Mars is small, its ability to induce fire can not be underestimated in environments with high concentrations of flammable dust such as sanding and paint.
5. The motor knife is short-circuited and the wire is aging. High-power appliances will accelerate the aging of the wires. When the plugs are plugged or unplugged or the motor blades open and close, the sudden and strong current will generate electric sparks, which will easily induce fire.
6, matches, cigarette butts, lighters, etc. The rigorous carrying of fire into the furniture workshop is a requirement of many mahogany furniture factories. The wood dust in the dust collector is ignited at approximately 470 ° C. In a high concentration dust chamber, the ignition temperature may be lowered to 260 ° C. The temperature of a newly ignited match is about 500 ° C, and the temperature at the center of the cigarette is generally 700-800 ° C. Therefore, the temperature of matches and cigarette butts is enough to cause a fire.
Fire inspection content
1. Check whether the fire safety measures of important substances in the process of production and storage meet the requirements and how they are implemented;
2. Check whether the building structure, layout, water source and safe evacuation facilities meet the requirements;
3. Check whether the employees at the ranks pay attention to fire safety, and whether the fire safety responsibility system and fire safety system at all levels are implemented;
4. Check whether the fire hazard is actually rectified, and whether the fire and fire accidents are seriously traced and dealt with.
5. Check whether the employees are not allowed to smoke or open fire in the fireworks area.
6. Check the equipment that can generate a lot of dust and sawdust, and whether the equipment operator cleans it regularly.
7. Check whether the fire-fighting equipment, equipment and personal protective equipment are repaired and maintained according to the specified time and replaced in time.
8. Check whether the flammable and explosive materials and the sanitary conditions in each workshop are piled up in the workshop.
9. Check whether the evacuation passages and safety exits are unblocked, and whether the safety evacuation signs comply with the state regulations are set.
10. Check if the electrical wires are randomly connected or placed indiscriminately.
What to do if there is a fire
1. Timely and accurate alarm: When a fire occurs, it should be notified to the fire brigade at the same time as the fire to the surrounding personnel, and report to the unit leader and relevant departments.
2, the fire of the beginning: the development of the fire is the beginning, development, violent, falling and extinguishing five stages. At the beginning of the fire, the burning area is not large, the flame is not high, the radiant heat is not strong, and the fire development is relatively slow. If it is found in time, the method is appropriate, and the fire can be quickly extinguished with less manpower and simple fire extinguishing equipment. This stage is the best time to put out the fire. At the same time as the alarm, we must fight every second, seize the time, and strive to eliminate the fire in the initial stage.
3, self-rescue in the fire: casualties in the fire, mostly occurred in the upstairs, or due to escape difficulties, or suffocated by smoke, or forced to jump off the building, or burned by fire.
(1) In the event of a fire, you must keep your emotions calm and try to escape.
Determine your location, judge the fire according to the surrounding smoke, flare, temperature, etc., do not blindly take action;
(2) If there is a fire in the room and the smoke is dense, take measures to cover the nose with a wet towel;
(3) If the situation permits, the whole body will be wet. If the clothes are on fire, the clothes will be quickly taken off or lying down on the ground, until they are extinguished, and then the fire escape channel is searched;
(4) When encountering a fire indoors, when opening the door, the door should be opened and the door should not be opened;
(5) When a high-rise encounters a fire, do not take the lift and take the stairs to escape;
(6) Because the fire is too strong, you must escape from the building. You can jump off the second floor, but you should choose a ground that is not hard. At the same time, you should first drop the bedding from the upstairs to increase the cushion of the ground, and then slide the window. Under the hood, try to reduce the height of the drop so that the feet can be grounded first or the ropes can be found in the strips when the situation permits. They are connected, one end is fastened to a firm door or window or Other object, and then the rope or bed sheet is followed. Slide down.
4. Evacuation in a fire: Evacuation is the evacuation of people and materials threatened by fire to a safe place. This is an important measure to reduce casualties and material losses.
