Five mistakes in using personal protective equipment

Wearing appropriate protective equipment is the last line of defense to protect the life and health of workers in enterprises. The correct use of appropriate level of protective equipment can effectively prevent occupational poisoning and occupational diseases. However, in the enterprise inspection, it is found that many enterprise managers and workers have misunderstandings in the use of personal protective equipment, which is prominently reflected in the following five aspects: personal protective equipment can be worn or not, gauze mask can be used for dust prevention. The municipal Safety Supervision Bureau reminds that enterprises should attach great importance to it and take effective measures to eliminate the misunderstanding of the use of personal protective equipment< [misunderstanding 1] personal protective equipment can be worn or not. personal protective equipment can eliminate or reduce the impact of occupational hazards on workers’ health. According to the law on prevention and control of occupational diseases, employers must provide qualified protective equipment for workers, and workers are obliged to wear protective equipment [misunderstanding 2] there is no peculiar smell in the workshop, so it is not necessary to wear personal protective equipment many harmful gases are colorless, odorless and tasteless, without any warning and can not be felt. Even if there is flavor, there are limitations and individual differences in sensory organs’ perception of the outside world. Therefore, over believing in feelings may lead to occupational poisoning [mistake 3] gauze mask can be used to prevent dust ordinary gauze mask cannot be used as dust mask. Although the gauze mask we use now is cheap, it can absorb sweat in summer and keep warm in winter, but this kind of mask (16 layers thick) can not protect against the hazards of respiratory dust, which is easy to cause pneumoconiosis< [mistake 4] medical masks are used to prevent poison medical masks can prevent diseases from spreading through droplets, but they can’t filter toxic gases. For different poisons, it is necessary to use different filter effect of anti-virus masks. Anti general volatile organic gas can use activated carbon anti-virus mask [mistake 5] the filter material of dust mask can not be washed with water. The high-efficiency filter material used for dust masks is usually non-woven fabric, and some rely on the electrostatic charge on the fiber to filter respirable dust. After washing, the microstructure of the filter material will be damaged, with invisible cracks and holes, a large amount of electrostatic charge will be lost, and the filtration performance will be seriously reduced
