There are various types of dust masks, and the selection must be based on different job requirements and working conditions.As half masks, all dust masks are suitable for environments where the concentration of harmful substances does not exceed 10 times the occupational exposure limit, otherwise a full face mask or a higher protection level respirator should be used. If the particulate matter is highly toxic, carcinogenic and radioactive, the filter material with the highest filtration efficiency should be selected. If the particulate matter is oily, be sure to select a suitable filter material. If the particles are needle-like fibers, such as slag wool, asbestos, glass fibers, etc., since the dust mask cannot be washed with water, the mask with tiny fibers may cause facial irritation at the facial seal and is not suitable for use.
Although the structure of the dust mask is simple, it is not easy to use. For protection to really work, it must be used correctly. First of all, choosing a suitable and suitable mask is the first step in protection. Secondly, you need to wash your hands and nasal cavity before wearing it, wear it according to the instructions for use, and ensure the correct position (no leakage) every time you wear it. It is also necessary to insist on wearing it during dust exposure operations, find out the signs of failure of the mask in time, and replace it in time. Different dust concentrations are different in the environment, each person's use time is different, the dust holding capacity of various dust masks is different, and the use and maintenance methods are different. These will affect the service life of the mask, so there is no way to uniformly stipulate the specific replacement time. When any part of the dust mask is broken, broken and missing (such as nose clips, nose clip pads), and when there is a noticeable increase in breathing resistance, the entire mask should be discarded. In addition, the dust mask should be folded to avoid secondary pollution in the mask.
