Mainly amber, timely, crystal and other materials are processed into jewelry, watch accessories, jewelry and other products. Due to the technological characteristics of jewelry processing, stones weighing several kilograms are cut into small pieces and then carved into exquisite carvings. During the processing, not only the dust concentration is high, but also the noise is not small. At the same time, cyanide, benzene series (benzene, toluene and dimethyl), methanol and other chemicals are used. These occupational hazards are easy to cause harm to human body and cause occupational diseases.

Dust hazard:

Silicosis is caused by long-term inhalation of dust containing free silica.

How to prevent:

In order to prevent dust from entering the lungs, you must wear a dust mask. The choice of dust mask is also very important. Generally, simple masks are simple to make, light in weight and low in cost, but they have dust-proof rate, easy wetting of filter materials and increased resistance. The finer the dust in the workplace, the worse the protective effect.

After testing, when the dust concentration of 8- 12 gauze mask is below 7mg/m3, the dustproof rate is only 60-80%, and the anti-radioactive aerosol rate is 6- 10%. The invention has the advantages of simple structure, high dustproof, low resistance, light weight, no influence on vision, reusability, low cost, wide application range, convenient use and the like. The dust-proof effect on silicon dust and other dust is ideal, and the dust-proof rate reaches 95%.
