The replacement method of asbestos brake pads is analyzed
In the proportion of asbestos brake pads, asbestos accounts for 40-60%, but people now find that most asbestos has potential harm, asbestos has been confirmed by the medical community is a carcinogen, its needle-like fibers are easy to enter the lungs and stay, causing stimulation, and ultimately can lead to lung cancer, but the incubation period of this disease can be as long as 15-30 years, So people are often unaware of the dangers caused by asbestos.
As long as the asbestos fiber is fixed by the friction material itself, it will not cause harm to the health of the staff, but when the asbestos fiber is emitted along with the brake friction to form brake dust, it may become a series of health effects.
According to the tests made by the American Occupational Safety and Health Association (OSHA), each routine friction test, brake pads will produce millions of asbestos fibers distributed into the air, and this fiber is far smaller than human hair, can not be observed by the naked eye, so a breath may suck thousands of asbestos fibers and people are unaware. Similarly, if the brake dust in the brake drum or brake components is blown away with an air tube, countless asbestos fibers can also be blown into the air, and these dust will not only affect the health of the working technician, but also cause health damage to any other personnel present. Even some simple operations such as hitting the brake drum with a hammer to loosen it and let the internal brake dust out can produce large amounts of asbestos fibers that float into the air. Even more worrying: Once the fibers float in the air for hours, they stick to clothes, tables, tools -- you name it. Any time there is a disturbance (such as air flow when cleaning, walking, or using air tools), they will all float back into the air. Often, once this material gets into the work environment, it stays there for months or even years, causing potential health effects for people working there and even customers.
