PPE

There are several misunderstandings in the use of personal protective equipment

Misunderstanding 1: personal protective equipment can be worn or not

experts pointed out that 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

mistake 2: there is no peculiar smell in the workshop, so you don’t need to wear personal protective equipment.

experts point out that many harmful gases are colorless, odorless and tasteless, without any warning or feeling. 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 such a mask (even if it is 16 layers thick) can not protect against the hazards of respiratory dust, which is easy to cause pneumoconiosis. Special dust masks are needed for dust prevention

myth 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. General volatile organic gas can use activated carbon gas mask

mistake 5: the filter material of dust mask can not be washed by water. The high efficiency filter material used in the dust mask is usually non-woven material, and some rely on the electrostatic charge on the fiber to filter the respirable dust. After water 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

protective equipment is a kind of passive protective measures. 1n any case, we should first adopt advanced production technology and do a good job in engineering protective facilities, so as to actively prevent occupational diseases; Only when the protective facilities can not completely eliminate the occupational hazards can we consider to equip workers with appropriate personal protective equipment. 1t is worth noting that personal protective equipment is not omnipotent, any personal protective equipment has its applicability, there are limitations, need to consider the use of the environment and the scope of application of protective equipment
