What gas masks are used to prevent dust? Silica is best used
Silica dust protection, according to dust classification, belong to inorganic dust, long-term in this environment, not effective protection, easily lead to silicosis (pneumoconiosis is one of the most dangerous). Because of pneumoconiosis can not be healed, so now a lot of silica sand factory attaches great importance to the prevention of respiratory protection.
If respiratory protection is not carried out, pneumoconiosis can be easily induced. It has been reported in China that it is easy to cause mass pneumoconiosis.1, masks must be LA certification, access to GB2626-2006 "self absorption filter particulate respirator" certification level.2, due to silica dust easily lead to pneumoconiosis, it is recommended to buy KN100 grade for protection (protection rate of ultrafine dust more than 99.97%).3, it is recommended to buy size distinction mask.4, recommend buying silicone material, double half mask type. Compared with the disposable mask, the leakage rate of the face mask is low, and the effect is good.In this way, buy dust masks, effective prevention of pneumoconiosis. Now, the domestic KN100 grade protective mask costs only about 30 yuan per month, breathing smoothly.Gas masks are mainly protective against toxic and harmful gases. Although there are protective masks against dust and gas, they are not products used for dust protection.
In accordance with the prevention and control measures for occupational diseases, silica dust should be protected against dust masks (self absorption filters, particulate respirators).
