Two Chloroethane Shoemaking Enterprises Need Caution

This year, 39 workers in the bags and shoemaking factories in Guangzhou Baiyun District were poisoned after exposure to toxic glue. 3 of them died. It was diagnosed as "occupational two chloroethane serious poisoning". It is reported that the main reason for the poisoning is the illegal use of inferior glue containing 1, 2- two chloroethane and other toxic substances. The test showed that the highest content of 1, 2- two chloroethane in some samples was 58.99%. In addition to the cold weather, workers closed doors and windows, causing toxic substances to gather and exceeding the standard. In addition, the production technology of enterprises is backward, the consciousness of safety production is weak, the occupational health and safety management is neglected, the ventilation and detoxification facilities in workplace, and the lack or imperfection of labor protective equipment are also one of the main causes of poisoning.

" Two chloroethane "Why?"? Why did it cause workers to be poisoned? Experts from the Shenzhen chemical poisoning consultation center of the Shenzhen occupational disease prevention and treatment institute said that two chloroethane is a chemical product, similar to chloroform odour and sweet, colorless transparent oil like liquid. At present, it is mainly used as raw material for chemical synthesis, industrial solvents and adhesives such as ABS514 glue, 3434 glue, quick drying adhesive, etc. it is widely used in bags and bags. Shoemaking Toys, electronics, rubber products and other industries.

Two the two isomers of chloroethane often coexist in different proportions. Symmetrical bodies, such as (1,2 - two chloroethane), belong to highly toxic species. Asymmetrical bodies (such as 1,1 - two chloroethane) are micro toxic. It is absorbed by respiratory tract, digestive tract and skin, mainly absorbed by respiratory tract and rapidly distributed throughout the body after entering the human body. Poisoning is mainly acute or subacute poisoning, mainly manifested as excitement, headache, nausea, and severe central nervous system depression, confusion, vomiting, abdominal pain, diarrhea, liver and kidney damage, severe dyspnea, convulsion, coma, pupil dilatation, blood pressure drop, acidosis and muscle tone decrease, which can cause toxic brain edema. In the surrounding areas of Shenzhen, Dongguan and other places, two chloroethane poisoning occurred in workers in toy factories and electronic factories who contacted glue containing two chloroethane, which usually occurred in a poorly ventilated working environment. The mortality of the disease was high.

How to prevent occupational two chloroethane poisoning Professional defense experts point out that we should first search for low toxic substitutes without 1,2 - two chloroethane. Enterprises should have a good idea of the composition of the chemical glue used. When purchasing glue, the supplier should produce material safety information of the glue, and use the glue without two chloroethane to prevent poisoning. Secondly, we should strengthen the ventilation of work posts. If it is necessary to avoid two chloroethane in other glue due to other reasons, it is necessary to find ways to reduce the concentration of two chloroethane in the air. The most common way is to strengthen the ventilation of the work place, ensure that the fresh air enters, install the pumping and draining facilities, and drain the glue containing two chloroethane in the air, so that the concentration of two chloroethane in the work place is lower than the national hygienic standard. Besides, occupational health examination for employees should be done well. People suffering from nervous system organic diseases, mental illness, liver and kidney organic diseases and systemic skin diseases can not engage in the work of contacting two chloroethane.
