The main occupational health hazards of rubber are in rubber mixing, calendering and vulcanization. The possible main hazard in rubber mixing is carbon black dust. In the calendering process, the possible main hazards are benzene, toluene and xylene. The possible hazard of vulcanization is also triphenyl. The degree of harm also depends on the MSDS of raw materials and additives. The harm of new additives is relatively low.
There is a little dust pollution in the open mill, and the internal mixer used for tires has less dust, which is basically harmless. The raw materials have no health hazard except that some anti-aging agents have skin contamination and itching, and there is no harm in the production process without adding powder.
If the fumes in the vulcanization process are pure raw rubber, there is no harm. If it is mixed with reclaimed rubber, the fumes are mainly the smell of pine tar, but it is a little unpleasant, and the harm to health is very small. It can be said that the harm to health in the rubber industry is lower than that of electronics. industry and other chemical industries. Slightly heavier than the machining industry.
Dust pollution may lead to silicosis. But the industry rarely sees serious ones. Because the contact time is not very long. The inhalation is mainly carbon black and light calcium powder, a small amount of sulfur and accelerators, antioxidants. Do rubber work, wash your face more, drink more water, drink milk, and eat pig blood for prevention.
