Analysis of the replacement method of asbestos type brake pads
Asbestos accounts for 40-60% of the composition of asbestos-type brake pads, but people have now discovered that most asbestos is potentially harmful. Asbestos has been confirmed by the medical community to be a carcinogen, and its needle-like fibers can easily enter the lungs and cause If it stays, causing irritation, it can eventually lead to the occurrence of lung cancer. However, the incubation period of this disease can be as long as 15-30 years, so people often do not realize the harm caused by asbestos.
As long as asbestos fibers are fixed by the friction material itself, they will not cause harm to the health of workers. However, when asbestos fibers are emitted along with braking friction to form brake dust, they may become the source of a series of health effects.
According to tests conducted by the U.S. Occupational Safety and Health Association (OSHA), every time a routine friction test is performed, the brake pads will produce millions of asbestos fibers into the air, and these fibers are far smaller than a human body. Hair is invisible to the naked eye, so thousands of asbestos fibers may be inhaled in one breath without people noticing. Similarly, if you use an air pipe to blow away the brake dust from the brake drum or brake parts, you can also blow countless asbestos fibers into the air, and these dust will not only affect the health of the working technician, but also affect anyone. Damage to the health of other persons present. Even simple operations such as tapping the brake drum with a hammer to loosen it and release the internal brake dust can produce a large amount of asbestos fibers into the air. What’s even more worrying is that once the fibers float in the air they will remain in the air for several hours and then they will stick to clothes, desktops, tools, and any other surface you can think of. Any time they encounter agitation (such as air currents when cleaning, walking, or using pneumatic tools), they will float back into the air. Typically, once this material enters a work environment, it will remain there for months or even years, causing potential health effects to the people working there and even customers.
