How do sculptors prevent pneumoconiosis?

Sculptors, especially stone carvers, have high dust concentration and contain a lot of silicon dioxide, which is easy to cause pneumoconiosis.

Pneumoconiosis has the characteristics of long onset time, gradual deterioration and incurable medical treatment. As practitioners, the prevention of pneumoconiosis should start with individual protection and scientifically choose dust masks.

Dust masks, as special labor protection articles, must pass GB2626-2006 certification.

1 Therefore, the choice of masks should also be made according to the national standard. In the national standard, for dust and oily particles, protective masks are divided into oil-proof (oil fume, oil mist, dust, smoke, fog and microorganisms, denoted by KP) and dustproof (dust, smoke, fog and microorganisms). For dustproof, the protection levels are KN 100, KN95 and KN90. They represent the protection rates of ultrafine dust ≥99.97%, > 95% and > 90% respectively.

2. Masks are divided into disposable, replaceable cotton filter-type half masks and full masks. For long-term occupational protection, especially in the environment with high dust concentration and heavy smoke, it is recommended to use a replaceable cotton half mask. Disposable masks are mostly high-grade regardless of size.

3. The mask material is silica gel, plastic, etc. Silicone material is soft and comfortable, with low facial pressure.

It is particularly important that the mask is sized according to the national standards. Many masks vary in size, and the effect will vary from person to person.

5. There are two kinds of masks, one is to cover the mouth and nose, and the other is to cover the mouth, nose and jaw. The second contact mask is large, with good sealing and low pressure sensitivity.

6, choose low respiratory resistance, is conducive to improve work comfort and improve work efficiency.

Don't neglect respiratory protection, use fake, fake, gauze, towels, etc. As a mask, it is easy to cause lung diseases. In the stone carving industry, the incidence of pneumoconiosis is very high without respiratory protection. N 100 half mask should be selected for protection.

At present, some common dust masks with N 100 grade can ensure the protective effect and breathe smoothly, and the cost is about one yuan a day, which can be borne by enterprises and individuals at their own expense. At present, N 100 dust masks such as 3M8233 and Baoshun 'an 320 1 are used in many harsh environments in China.
