Asbestos health certificate

The harm of asbestos is pollution: about 95% of the asbestos used in the world is chrysotile, and its fibers can be split into very fine filaments. For every 65,438+0 tons of asbestos consumed in industry, about 65,438+00 grams of asbestos fibers are released into the environment. 1 kg asbestos contains about 1 10,000 fibers. Metafibers are generally 0.5 microns in diameter and less than 5 microns in length, which can be suspended in the atmosphere and water for weeks and months, causing continuous pollution.

The harm of asbestos rope is carcinogenic: the harm of asbestos rope is that asbestos itself is not toxic, but it has a strong stimulating and carcinogenic effect on human body. The biggest harm comes from its fibers, very fine fibers. When these tiny fibers are inhaled into the human body, they will attach and deposit in the lungs, causing lung diseases, such as asbestosis, pleural and peritoneal mesothelioma.

These lung diseases often have a long incubation period and can cause lung cancer in severe cases. Therefore, it is necessary to dispose of the waste asbestos rope reasonably and avoid throwing it away at will.

Extended data:

In 2006, the World Health Organization (WHO) proposed that the most effective measure to eliminate asbestos-related diseases is to stop using all kinds of asbestos products. In the same year, the resolution of the International Labour Organization (ILO) on asbestos also called for the prohibition of the use of asbestos and the effective identification and management of asbestos. ILO believes that this is the most effective way to protect workers from asbestos hazards and prevent asbestos-related diseases and deaths.

However, the International Agency for Research on Cancer (IARC, 20 12) has sufficient evidence that chrysotile can cause malignant tumors in lung, pleura and peritoneum, so it is not appropriate to ban only amphibole asbestos, but also chrysotile asbestos.

Asbestos has been banned in 52 countries, as well as in the European Union, Japan and South Korea.
