How to wear a dust face mask
Although the dust face mask has a simple structure, it is not easy to use. Choosing a suitable and suitable mask is only the first step of protection. If the protection is to be effective, it must be used correctly. This includes not only wearing according to the instruction manual, ensuring that each wearing position is correct (not leaking), but also in dust collection operations. Always wear it in time, find the signs of failure of the mask in time, and replace it in time.
Different dust collection environments have different dust concentrations, different usage times for each person, different dust holding capacity of different dust masks, and different maintenance methods. These will affect the life of the mask, so there is no way to uniformly specify the specific replacement time. . When any part of the dust mask is damaged, broken and lost (such as nose clips, nose clip pads), and the respiratory resistance is obviously increased, the entire mask should be discarded.
Whether it is anti-virus or dust-proof, any filter element should not be washed, otherwise it will damage the filter element. If you feel other discomfort during use, such as too tight headband, high resistance, etc., you are not allowed to change the length of the headband or loosen the nose clip. You should consider choosing a more comfortable mask or other type of respirator. Not only is the respirator suitable for users, it should also have a certain degree of comfort and durability, which is reflected in the slow increase in breathing resistance (large dust capacity), the light mask, the headband is not easy to loose, the mask is not easy to collapse, the nose clip or head The strap is firmly fixed, the material is selected without odor, and it is not irritating to the skin. This is usually only those workers who have used dust masks for a long time and have the most experience and right to speak.
