[How to prevent a fire in a cold storage in Taizhou, Zhejiang?]
Release date:[2020/10/30] Is reading[482]次

At 11:56 on October 16, a fire broke out in the warehouse of the Workers’ Lugan Aquatic Products Wholesale Market in Jiatu Street, Jiaojiang District, and the Fire Rescue Brigade of Jiaojiang District dispatched forces to the scene to fight the fire. After preliminary understanding, the burning building was a one-story brick-concrete structure with no casualties. At present, the cause of the fire is under investigation.

   Problems exposed by the fire:

      1. The employees of the company are not very aware of fire safety, and they did not take effective measures immediately after the fire was discovered.

  2. The fire-fighting facilities and equipment are not fully equipped, and there is no fire hydrant around the fire location.

  3. I am not familiar with the emergency response process. After the fire broke out, the employees in the factory did not carry out fire fighting and rescue operations.

   Fire case

   On the morning of October 2, 2018, a foam pile in an abandoned factory in Minhou County, Fuzhou City, Fujian Province suddenly caught fire with no casualties. It is understood that the fire was in an ice store in the factory, which contained some foam and ammonia pipes, but it was abandoned and no longer used.

   On August 1, 2018, a fire broke out in the first warehouse of the Asian Vegetable High-tech Seed Industry in the agricultural demonstration park on the south side of Yehai Avenue, Haikou City, Haikou City. The fire area was about 2,000 square meters. Fortunately, no casualties were caused. Investigations at the fire site revealed that the burning building was a single-story steel-structured refrigerated warehouse. The main igniting substances were frozen food and packaging materials stored in the warehouse.

   On April 24, 2018, a fire broke out in a cold storage at the Old Fruit Street Refrigeration Factory in Chenggong Long Street, Kunming City, Yunnan Province. When the fire broke out, the owner and his wife were trapped. After emergency rescue, the personnel were rescued safely.


How to prevent cold storage fires? ?

  What are the reasons for the fire in the cold storage?

   1. Fire is prone to occur during maintenance

   During pipeline inspection and repair, especially pipeline welding, it is very easy to cause fire.

  2. Fire is easy to occur when cold storage is removed

  When the cold storage is dismantled, the residual gas in the pipeline and a large amount of combustible materials in the insulation layer may encounter the fire source, and it is likely to burn.

  3. Aging or improper use of electrical equipment may cause a fire

  Improper use of lighting, cold storage fans, electric heating doors used in cold storage, and aging of wires can also cause fires.

   4. Wiring problems cause fire

  In cold storage fires, fires caused by wiring problems account for most of the fires, with the most short circuits. There are mainly these situations:

The cold storage door is left open for a long time, hot air enters the cold storage, the condensed water in the storage increases sharply, and the water droplets cause a short circuit on the wires; the motor runs for too long and overheats, causing condensation water when defrosting, and the water hits the wires to cause a short circuit; the line is used for too long, The insulation layer is aging and broken, causing the two wires to collide; pulling and connecting the wires in disorder will mechanically damage the "jacket" of the wires and cause short circuits.

  What are the characteristics of cold storage fires?

   1. Burning fiercely, forming a three-dimensional fire

   The four walls of the cold storage are vertically connected, and there are chimney-like hollow sandwich walls; there are asphalt and linoleum in the insulation layer, and there are cork, fiberboard, rice husk and plastic in the storage. Once a fire occurs, the vertical and horizontal directions will spread quickly.

   2. The burning is hidden, it is not easy to find the ignition point

   When the cold storage insulation layer catches fire, the smoldering time is longer, and the smoldering flame is not easy to find outside the wall.

  3. The smoke is large, the temperature is high, and it is inconvenient to extinguish the fire

   The cold storage has few entrances and exits. The doors of the cold storage and the staircases of the multi-story cold storage are easily blocked by flames. The heavy smoke rolls down and it is difficult for the gunners to attack inside or upward.

   4. There are many poisonous gases and there is a danger of explosion

   After a fire in a general cold storage, there is insufficient air, insufficient combustion, and high carbon monoxide content. If foam plastic is used as insulation material, poisonous gas will be released after fire. If a large amount of ammonia gas is sprayed out of the tube, and the concentration reaches 15.7-27.4%, it will explode when exposed to an open flame.

   What measures should be taken to prevent fire in cold storage?

  1. The construction and construction of cold storage must comply with relevant safety regulations such as "Building Regulations" and "Cold Regulations"

  The cold storage site selection should adhere to the principle of keeping away from residential areas and major traffic arteries, and reliable protection measures should be taken in the design and installation of power distribution lines.

   2. Intensify supervision and implement the safety responsibility system

   Relevant units should strengthen supervision and law enforcement, and immediately rectify problems when they are found. Illegal operation is strictly prohibited, and the cold storage is designed and constructed by the corresponding qualified unit, and the construction is carried out according to the operating regulations, and the certificate is used.

  3. Improve safety awareness and strengthen daily supervision and management

  Establish and improve various fire safety management systems, recognize the importance, necessity and regularity of safe work in cold storage, implement the work in practice, and prevent problems before they occur.
