Experts explain the mistakes in the use of labor protection articles

in the production process, workers will inevitably be exposed to dust, harmful gases, noise and other occupational hazards, such as the lack of ventilation, dust prevention and other engineering protection facilities in the workplace, which is easy to lead to occupational poisoning and occupational diseases. Experts from Shenzhen occupational disease prevention and control hospital suggest that workers should wear appropriate protective equipment as the last line of defense to protect their lives and health. Correct selection of appropriate level of protective equipment can effectively prevent occupational poisoning and occupational diseases

experts of occupational disease prevention and control pointed out that personal protective equipment is the first level of prevention in the comprehensive measures to prevent occupational hazards. When the working conditions can not be improved from the protective equipment, it is still the main means of protection. Personal protective articles include protective clothing, protective shoes and hats, protective gloves, protective masks and glasses, ear protectors, respiratory protectors and skin protectants, etc. The purpose of protection can be achieved by using their functions of shielding, absorption and filtration. 1n the selection of personal protective equipment, we should not only pay attention to the protection effect, but also consider whether it meets the physiological requirements. 1n order to achieve the protection effect, we need to strengthen the management and inspection and maintenance< Experts pointed out that there are several misunderstandings in the use of personal protective equipment by many enterprise managers and workers: misunderstandings 1. Can 1 wear personal protective equipment or not? experts pointed out that personal protective equipment can eliminate or reduce the impact of occupational hazards on workers’ health, The employing unit must provide the workers with protective articles that meet the requirements, and the workers have the obligation to wear protective articles< The experts pointed 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< 3. Gauze mask can be used to prevent dust experts pointed out that ordinary gauze mask can not 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< Medical masks are used for anti-virus.experts point out that 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< The experts pointed out that the filter material of the dust mask can not be washed with 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 experts pointed out that 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
