At two o'clock in the morning on May 31, Cao Quancai and other 6 workers at the Minjiang Road Station of Hangzhou Metro Line 1 suffered from headaches, vomiting, limb weakness, joint pain and other symptoms. After being diagnosed by experts, it was common for them to develop symptoms. Diver's "decompression sickness".
"Decompression sickness" was first recorded in 1841. The symptoms of decompression sickness were skin rash, collapse, joint pain, visual disturbance, balance disorder, dyspnea, fatigue, paralysis, paralysis, unconsciousness, and death.
Chen Zhuo, executive deputy general manager of China Railway Second Bureau, described the situation at that time: For the tool changer, they created a 1.7 atmosphere pressure zone underground to prevent the underground from collapsing and sinking. Then let the operator enter the “barrier bunker†and slowly increase the pressure of the brake chamber by 1.7 atmospheres. Only under the same pressure condition, the personnel in the “people bunker†can open the door to enter the earth bunker operation. However, the staff only took one hour to decompress before leaving the warehouse.
The reporter sent a report on the scene, and many witnesses thought that it was gas poisoning. They did not know what "low-pressure illness" was. They were still operating the project and thought that the body was fatigued as a kind of collapse performance.
Summer is a season of high accidents for electrical and mechanical workers. Except for high-temperature heat stroke, burns, and other common diseases, similar to the “low-pressure illness†in the “subway accidentâ€, it is also a labor-intensive industry that must be vigilant.
In particular, the hardware and electromechanical industry, including many high-risk nature of the work content, the field operations, for example, on-site medical diagnosis and treatment is incomplete, will allow hardware and electronic and mechanical staff life hanging safety rope.
Careful readers can find that walking on the urban avenue, you can see a large number of electrician masters, without any security measures, climbing up the ladder to carry out operations, the summer decoration season, it is to see a large number of decoration of mechanical and electrical workers, often in On the spot, throwing cigarette butt heads, empty hand touch electrical equipment.
What is the working status of the domestic electromechanical workers? The author consulted relevant association experts.
Industry insiders believe that with the economic development, the hardware and electronic machinery industry has derived a large number of branches. In the national oilfield development and other national projects, the operation specifications are very detailed and standardized, but the general engineering is still due to the lack of adequate pre-job training. A lot of operational accidents.
The author also learned from some electromechanical companies that many times, some electromechanical employees will be in trouble, neglecting training, and there will always be opportunistic psychology in practical operations, often in order to increase efficiency, or even skip some steps, which is also their own lives. Irresponsible performance.
It is understood that with the advent of summer, the country is about to enter the main flood season, and persistent high temperatures, heavy rain, and thunderstorms will cause adverse effects on the safe production of buildings. In the course of construction, mechanical and electrical workers must be safe for themselves and their families. headed by.
