[July 15th: warehouse fire in Ying Lin garment factory, Jinjiang]

At 12:20 on the 15 th, a fire broke out in a clothing factory warehouse in Jinjiang, Ying Lin, Ying Lin. After receiving the alarm, Longhu fire squadron firefighters rushed to the scene for disposal. After 1 hours of hard fighting, the blaze was extinguished. Fortunately, no casualties were caused.

What happened in the clothing factory was the three layer of a 5 story building. When the fire arrived at the scene, the flames continued to emerge from the three windows and smoke billowing. The firefighters were able to organize fire fighting, and the fire was quickly controlled.

According to a witness at the scene, when the factory discovered the fire, the workers in the factory had stopped working for lunch, and the location of the fire was just the warehouse of the factory, which contained a lot of cloth and jackets and other textiles and clothes.

At 13:30, the fire was finally put out. Due to the timely rescue, the fire did not spread further. The fire caused the three storehouse of the garment factory to overrun the area of more than 200 square meters. At present, the specific cause of the fire is still under investigation.

The local fire and Rescue Department dispatched more than 10 fire engines to the scene for disposal. At present, the fire has been controlled, there are no casualties, and the burning material is cloth.

Textile enterprises must prevent themselves from burning. ]

1. Raw materials are flammable and fire is fast.

Most of the raw materials in cotton spinning enterprises have low ignition points, which are very likely to cause fire. If the ignition temperature of cotton is 210 degrees, the cotton fiber in loose state is 150 degrees, which is 15% to 26% faster than that of wood. In textile factories, cotton, cotton rolls and sliver are scattered everywhere, and they will quickly become a disaster if they fire.

2, dust accumulation, combustion and even pieces.

In the process of cleaning and carding, textile enterprises will produce a lot of tidbits and cotton dust. With the air flow around the workshop, they will accumulate on beams, interlayers and even walls. The accumulation of fibers, flowers, cotton dust thermal conductivity is poor, heat is difficult to distribute, once encountered Mars, fire, it will quickly burn together.

3. Air conditioning helps to form a vicious circle.

At present, most cotton spinning enterprises use "central air conditioning" to control the temperature and humidity of the workshop, and form a connected system in the whole production process. However, after encountering a fire, these pipes are not only easy to burn, but also blow up oxygen and oxygen at an average wind speed of 2 to 3m/s to form a convective effect in the fire field, increase the fire and send the fire to all parts of the workshop and other levels to form an interlaced fire scene and larger combustion space.

4. Concealed concealment and captain of the delay

The interlayer of the cotton textile workshop is a relatively closed space, which is interconnected with each other, and the line of vision is blocked by the wall. Once the fire occurs, it has the characteristics of fast heating, strong smoke and strong concealment. When people perceive the smoke, the fire has reached the stage of intense combustion. At this time, the rescue is not only delayed the best time to save the fire, but also brings difficulties to the rescuers in judging the fire source.

5, densely staffed, smog threatening.

The textile industry is a typical personnel intensive industry. Because the fire occurs in a relatively closed workshop, there will be a lot of smoke in the combustion process. With the spread of wind pipes and interlayers, there will be a visual misunderstanding of the employees and firefighting rescuers, causing the scene of the fire to be in a state of darkness, panic and confusion. On the other hand, it will seriously threaten the life safety of the employees, especially chemical fibers and synthetic fibers. There are a lot of poisonous gases in the smoke, which can easily cause suffocation and suffocation.

1, man-made reasons

(1) employees smoke. All workshops, warehouses and cotton areas, including toilets, are strictly prohibited from smoking. However, most employees smoke in duty rooms and toilets, and cigarette butts are thrown away. There is a real danger: once the cigarette butts are thrown away, it is likely to ignite nearby combustibles and cause fires. The reason why there is no problem is that these smoked workers can consciously extinguish the finished cigarette butts. Just imagine, if you accidentally take the unburned cigarette end out of the toilet or the duty room, then you can throw it carelessly. What will happen?

(2) staff's technical inefficiency and negligence in their work. Operating machinery should be regulated according to the rules. Because of unskilled technology and careless work, violation of rules and regulations when operating machinery is bound to cause confusion in technology. This process is chaotic, which makes it easy for long time electrified and high heat equipment to cause fire by mechanical friction. Therefore, it is very important to pay close attention to the mechanical equipment in operation.

(3) intensive stacking and over storage. This is also an important cause of fire. Storage space should be kept according to specifications. Too dense, too long stacking time will lead to higher temperature in the storehouse, causing smoldering and eventually causing fire.

2. Natural causes

(1) lightning causes fire in the process of short-circuit or damage to electrical equipment and wires.

(2) when wet or rainy weather, rainwater penetrates into equipment and wires, causing short circuit, spark or arc discharge and fire.

3. Technological reasons

(1) aging of machinery and equipment.

Aging machines often produce high temperatures or sparks locally, which can easily cause fire in cotton textiles. In addition, in the production process, some silk floc recycling unreasonable, diffuse in the air, a long time will cause accumulation, in case of fire source is easy to cause a fire.

(2) electric wires are aged or ruptured, resulting in leakage and spark phenomena. This will also cause fire.

(3) fire in the spinning workshop of a cotton mill.

The main reason is that looms are more likely to be ignited by electrical sparks during the weaving process, such as stacking on electrical devices such as automatic devices and starting switches. Mechanical lack of oil and friction generate high heat or spark, which also ignites falling flowers.

(4) fire during the cotton cleaning process.

The reasons are as follows:

First of all, the cotton mixing machine, cotton opener, cotton feeder and dust removal machinery and equipment used in cotton cleaning, because of fast speed and small mechanical gap, will be rubbed and heated or even knocked out of Mars if there are hard impurities mixed up (especially iron, such as Tie Si) or because of mechanical parts misalignment and lack of lubrication in the rotation part. If the appliance is not used properly, it will also cause electric spark to cause cotton burning.

Secondly, in the process of carding and drafting, the cotton fibers with high humidity will be wound on the rotary parts such as leather sticks and rollers. The longer the time is, the more entanglement, the more friction will be between them, the greater the transmission resistance, and the higher the temperature will eventually cause the fire of cotton fiber or motor.

(5) the cotton gin is on fire.

Cause: seed cotton mixed with special. In seed cotton acquisition and transportation, matches, wire, nails, sand and other special debris easily mixed. If these seeds enter cotton gin with seed cotton, they will cause fire by mechanical friction and beating.

In addition, the high moisture regain of seed cotton is also one of the reasons. The seed cotton with high moisture regain is not bulky and stagnant. In the process of ginning, the fibers are twisted and squeezed, which easily obstructs the ribs and causes friction and fire.

(6) the flanking machine is on fire.

Cause: the most easily scattered place of the velvet machine is that of the saw blade and the upper row of miscellaneous knives, and the two is the row of saw blades and ribs. As the gap between the cars is not proper, the friction generates Mars, ignites the fluff, is swept into the road through the dust, and enters the dust tower through the dust cage, some of which enter the filter bag, and some float down in the dirt pile of the dust chamber.

(7) the cause of the fire of the baler.

The fire mainly comes from two aspects. One is the fire source produced by the baler itself, the two is the external fire. It is easier for the baler to catch fire and to pick up the running parts of the cotton picker and the cotton strapping machine. In the process of delivering cotton and stepping cotton, cotton fibers are easily entangled in the connection and transmission of the machine. Winding too much, and mixing with oil sludge, the machine running friction heat will cause fire. The external source of fire is the spark generated in the working box of the cotton gin, which causes fire with the cotton lint into the baler. Some kinds of fire are pressed into the cotton bag, causing a smoldering fire.

(8) other fires.

Such as improper electricity consumption, obsolete machines, wire aging, random connection, short circuit, overloading of equipment and poor contact will cause electric sparks to cause fires. Followed by improper operation of electric and gas welding. Because of mental paralysis and poor fire awareness, electric welding is carried out inside and outside the workshop or seed and lint yard. This will cause fire due to heat conduction and a large number of sparks to ignite cotton and fly fleece. Another is the dust explosion. Embossing and stripping produce more dust and fly fleece suspended in the air. The lower limit of these dust is 25.2 grams / liter. If the dust reaches the explosive concentration in the workshop, it will detonate if it meets fire.

1, do a good job in fire investigation, take reasonable measures to quickly and effectively implement rescue.

It is necessary to quickly understand whether there are personnel trapped, the location of the fire, the nature of the fire, the area of fire, whether there are explosives, and whether the fire is cut off. According to the situation of the site, reasonable fire extinguishing measures should be adopted, and contingency preparations should be made at any time to eliminate fire.

2, find a good source of water, correctly divide water to ensure continuous supply of water.

It is necessary to set the water diversion on the side of the fire threat materials to avoid the spread of the fire and to change the water diversion position in time.

3, prevent dust explosion.

In order to reduce the possibility of dust explosion, the spray water gun should be used to reduce the dust temperature and disperse the dust.

4, intercept the fire and prevent the fire from expanding.

When stacking fires occur, the speed of spread is fast and the area of fire is large. We should use the main force to block the fire in the current scope and prevent the fire from expanding.

5, carefully implement ventilation and smoke exhaust to prevent air convection from accelerating combustion.

Indoor textile fire, in its early stage of smoldering or fire, is not fully burned because of insufficient oxygen in the room. When it suddenly meets air convection, it can not only turn smoldering into complete combustion, but also cause an explosion of the mixture of carbon monoxide and air. Therefore, under the premise of insufficient fire fighting force or inadequate internal conditions, blind window breaking ventilation and smoke exhausting will be more harmful to the fire warehouse. Only when the location of fire points is identified and the internal forces are in place, can various forms be used for ventilation and exhaust heat dissipation. In this way, fire spots can be displayed, and fire sources can be directly attacked, and other fire extinguishing forces can be guaranteed to control the spread of fire.

6, take stacking or suffocating methods to extinguish fire.

As cotton and other smouldering are prone to occur, it is easy to cause internal smoldering on the outer layer of stack, and extinguishing the external fire does not mean extinguishing the entire stack fire. Coupled with the "drainage" of cotton, water can not enter the stack, so that the smouldering fire inside the stack can not be extinguished, and it is easy to revive.

For general small stacking, the method of stacking is usually used to extinguish the internal smoldering fire. It will be stacked and opened up and wet with water until the entire stack is extinguished. For larger stacking, if the stacking method is used, it will waste energy and time and waste water. For such stacking, many methods of water asphyxia should be adopted to extinguish fire. That is to say, without stacking, directly take multiple streams to attack the stacks evenly, causing the smoldering part of the stack to suffocate. When a plurality of streams attack the stacks evenly, the cotton fibers around the outer layer of the stack are tightly bonded to make the air inaccessible, causing smoldering not to continue. At the same time, multiple streams of water attack will reduce the temperature of stacking and reduce the cooling effect of stacking. This way can destroy the cotton fire with larger stacks, saving manpower and time and achieving good results.

In short, it is necessary to change the post fire fighting to prevent fire accidents in advance.
