In the daily production process, when workers work in confined spaces (such as entering towers, kettles, tanks, furnaces, containers, boilers, basements, pits, wells, sewers, and other closed places), accidents often occur, some people In the case of rescue, there is often a major accident causing casualties due to lack of personal protection or improper personal protection. For example, in February 2003, when a female worker in a MSG factory in Jiangsu was sampling from the acid regulating tank with a bucket, the bucket was accidentally dropped into the acid regulating tank, and another male worker was sucking the tank when helping the can. Residual ammonia gas, poisoning and suffocation, can not be out of the can, the workshop team leader and the workshop director have successively rescued people, all of them died due to the inhalation of ammonia. On August 30, 2003, a clearing team of a ship engineering company in Jiangyin City cleared the bottom of the transport ship. When the bilge oil layer remained about 30cm, one employee looked down at the bilge and was poisoned. The other three operators successively went down. The bilge saved people, causing 4 people to be poisoned, and 3 people died after being rescued. On May 21, 2006, during the construction of the sewage well of the Huangpu River Reconstruction Project A project in an economic and technological development zone in Suzhou City, Jiangsu Province, a hydrogen sulfide poisoning accident occurred. Two construction workers fell down and three other construction workers were rescued. Also poisoned and suffocated, resulting in a total of 5 deaths. There are still many such accidents that can enter the confined space without any relevant protective measures and save people from work accidents.
Almost every confined space accident is accompanied by casualties of rescue personnel. According to data in our country, more than 60% of the casualties were caused by attempts to rescue the victims who first entered the confined space without protection. Therefore, when entering a confined space operation or emergency rescue, it must have a clear understanding of its hazard and appropriate personal protection according to its characteristics.
In recent years, due to the lack of strict organization of construction units, construction workers lack the necessary safety knowledge, illegal operations, personal injury and death caused by confined space operations, and lack of emergency measures and first-aid knowledge, improper rescue and rescue A major accident involving multiple casualties. In the petrochemical, chemical and other industries, into the storage tanks, towers, reactors, underground pits, sewage wells and other space operations, management is slightly careless, easily lead to fire, explosion, poisoning, suffocation and other personal injury accidents. Therefore, the danger of entering a confined space must also be taken seriously. So, which environments are confined spaces?
The definition of a confined space is as follows:
1. The size of the space is sufficient for the workers to enter the work;
2. Workers are restricted from entering and leaving;
3. Structural design is not suitable for workers to work continuously in it.
At the same time, the confined space should also have the following characteristics:
1. Contains or may contain dangerous gases (atmosphere);
2. Contains substances that may cause erosion;
3. Have a structure that can cause people to fall into or suffocate;
4. Have a recognized health hazard.
Common confined spaces include various types of storage tanks and containers, sewers and other underground pipelines (such as cable trenches), underground facilities (such as tunnels), grain silos, railway tankers, ship cabins, tunnels, closed transport corridors, pits, wells. , sewers, pipes, flue, boilers, pressure vessels, hatches, caissons, shafts or silos.
