What occupational hazards exist in the production of chemical pesticides how to protect

Pesticide production is one of the serious occupational hazards of the industry, due to the discontinuity of production and process equipment is relatively backward, exacerbated the situation. Accident statistics show that poisoning, fire, explosion, is its main hazards. Due to the pesticide category more varieties, the production process involved in the unit reaction process and unit operation process is very extensive. Where the chemical unit reaction such as chlorination, oxidation, reduction, nitrification, ammoniation, sulfonation, disproportionation and unit operations such as reaction operations, extraction, extraction, distillation, separation, condensation, drying, etc. are involved, both continuous production (such as phosgene production), but also intermittent production, coupled with pesticide production of raw materials used in the production of intermediates, most of which are toxic and flammable, so it has a high degree of risk.

Physical protection of the production process of flammable material leakage, especially gas and vapor leakage, can cause an explosion, such as yellow phosphorus ignition temperature is very low, in the air will be spontaneous combustion, carbon monoxide, methanol, ethanol, benzene, etc. can be formed with the air and explosive mixtures; intermediates synthesis and pesticide synthesis process is not properly controlled, will make the reaction go out of control or the formation of decomposition of explosive substances, triggered by chemical explosions, such as trichlorophosphorus production if chlorine is too high, the production of chlorinated phosphorus. Phosphorus chloride in the production of excess chlorine will generate extremely easy to decompose and explode phosphorus pentachloride, diphosphorus pentachloride, phosphorus trichloride, methyl or ethyl chloride, methyl or ethyl sulfide and other intermediates of the synthesis of the once out of control, but also will explode, alkyl chloride and sulfide itself is unstable, easy to decompose and explode.

Respiratory protection of all pesticide raw materials, intermediates and finished products are mostly toxic to varying degrees. In the production process, acute poisoning are caused by leakage, and some of them are caused by maintenance failure or improper personal protection. Poisoning types can be divided into: organophosphorus pesticide poisoning, carbamate pesticide poisoning, pyrethroid pesticide poisoning, yellow phosphorus poisoning, phosgene poisoning, methyl isocyanate poisoning, in order to prevent poisoning phenomenon, the operation of wearing anti-virus equipment is necessary.

Hand protection in terms of pesticides, it is very serious harm to the human body, pesticides are mainly by three ways to enter the body: one is accidental contact with a large number of people, such as accidental ingestion; the second is the long-term exposure to a certain amount of pesticides, such as pesticide factory workers and users of farmers; the third is the daily life of contact with the environment and the residual pesticides in the food, which can be seen by the long-term contact with pesticides or pesticides, pesticides can be made to continue to accumulate in the body, posing a potential health risk to the human body. Accumulation of pesticides, pose a potential threat to human health, must be insulated from pesticides to do a good job.
