Selection of dust mask

Selection of dust mask

Anti-dust masks

Dust mask is a kind of protective equipment for workers engaged in dust operation and touching dust. There are many kinds of masks on the market, and their uses vary greatly. There are paper masks, cotton gauze masks, activated carbon masks, antibacterial masks for food processing, white gauze masks for doctors, welding and dust-proof masks for welders, dust-proof masks for dust operations, self-priming filter respirators for particulate matters, toxic and harmful gas masks, etc. Therefore, when choosing masks, we need to satisfy the needs of workers in different working environments. Improper selection will lead to waste, and even damage workers' health and occupational diseases.
Mask

In order to save cost, some units bought some low-quality dust masks that did not meet the requirements, and even used some white cotton masks or other ordinary masks as dust masks to distribute them to workers. If workers wear these masks for a long time, they may suffer from pneumoconiosis. Therefore, workers engaged in and touching dust need to understand relevant knowledge, strengthen protection and prevent occupational diseases.

Anti-dust masks

In addition to installing ventilation and exhaust equipment, keeping the working environment ventilated, using wet operation, dust isolation and other methods, operators should also be equipped with standard dust masks. The replacement of masks depends on the actual situation. If it is damaged or respiratory resistance is added, it should be replaced.
The operator shall wear the dust mask as required, and the nose and mouth shall be completely close to the inner wall of the mask without any gap, so as to prevent the dust from entering the lung through the nose and mouth. Some workers are not used to wearing masks at first, but they are used to wearing masks every day. It's very difficult to wear a mask in hot weather. You can ask to replace the self-priming filter dust-proof mask, leaving a lot of space for your nose and mouth. You feel much more comfortable when breathing. Dust masks should be kept clean, especially when touching nose and mouth. Because the filter element of dust mask and disposable mask cannot be cleaned with water, if it is dirty, it should be replaced.
