Personal protective equipment belongs to the first level of prevention in the comprehensive measures to prevent occupational hazards. When working conditions cannot be improved from protective equipment, it is still the main protective measure. However, there are several misunderstandings in the use of personal protective equipment by many corporate managers and workers:
1: personal protective equipment can be worn or not
Experts pointed out that personal protective equipment can eliminate or reduce the impact of occupational disease hazards on workers' health. The Occupational Disease Prevention Act stipulates that employers must provide workers with protective equipment that meets the requirements, and that workers are obliged to wear protective equipment.
2: No odor in the workshop, you can not wear personal protective equipment
Experts pointed out that many of the harmful gases are colorless, odorless, tasteless, and do not have any alertness and do not feel it. Even if it is odorous, there are limitations and individual differences in the sensory organs' perception of the outside world. Therefore, excessive belief in feelings may lead to occupational poisoning.
3: Gauze mask can be used to prevent dust
Ordinary gauze masks cannot be used as dust masks . The gauze masks we use today are cheap, sweat-absorbent in the summer, and warm in the winter. However, such masks (even if they are 16 layers thick) cannot protect against the hazards of respiratory dust from pneumoconiosis. Special dust masks are required for dust protection.
4: Medical masks are used to prevent poison
Medical masks can prevent disease from spreading through droplets, but they cannot filter toxic gases. For different poisons, use different respirator masks . General volatile organic gases can use activated carbon respirator .
5: Dust mask washing and reuse
Dust mask filter material can not be washed. The high-efficiency filters used in dust masks are usually non-woven materials, and some rely on electrostatic charges on fibers to filter respiratory dust. After washing, the microstructure of the filter material is impaired, cracks and holes that are invisible to the naked eye occur, electrostatic charges are also greatly lost, and the filtration performance is severely degraded.
Protective equipment is a passive protective measure. In any case, it should first adopt advanced production technology, do a good job of engineering protection facilities to actively prevent occupational diseases, and consider it as a protection facility if it cannot completely eliminate the occupational hazards. Workers are equipped with appropriate personal protective equipment. It is worth noting that personal protective equipment is not a panacea, and any personal protective equipment has its applicability, and it has limitations. It needs to consider the use of the environment and the scope of application of protective equipment.
Enterprises that have toxic and hazardous substances in their workplaces, if they do not have effective protective facilities or laborers do not use personal protection, can easily cause occupational poisoning and other serious accidents. For example, the electronic components cleaning and printing industries cause peripheral nerve damage due to the use of white hexane oil. Shoe and luggage manufacturing industries as well as spraying and adhesive production processes will use some organic solvents containing benzene and benzene series, which can cause damage to the blood system. Commonly there are leukemia, aplastic anemia and so on. Some physically sensitive workers may cause systemic skin damage due to exposure to trichloroethylene during the degreasing of hardware. Blasting, construction, sandblasting, and processing of gemstones caused silicosis due to exposure to higher dust containing free silica. Other occupational diseases may also be exposed to different occupational hazards, such as high temperatures in sanitation workers' operating environment, harmful gases and noise in automobile exhaust gas; professional drivers and gas station workers may be exposed to organic solvents in gasoline; white-collar workers working in office buildings There are electromagnetic radiation, ozone and other harmful factors in the workplace of the administrative personnel; there are pressures and occupational tensions in the banking and securities industry staff; the ultra-clean workshop workers are prone to change in tension, depression, anxiety, paranoia and other emotional changes.
Occupational disease prevention and control has become a hot issue in the society in recent years, and occupational hazards are everywhere. Only by raising awareness of the entire society, adopting comprehensive prevention and control measures, and improving the working environment can we effectively prevent and treat occupational diseases. In addition to the support and attention of the employer, the government and the competent authorities should also be more concerned about the laborers, strengthen supervision and law enforcement, ensure the safety of life and health of workers, and create a development-oriented, harmonious and innovative society. Make due contributions.

Check valve, clack valve, non-return valve, reflux valve, retention valve or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.
Check valves have a poppet design for reliable, leak-free operation. they are in-line mounted. Ports are "/12" for SAE or G-pipe threads. This new series has a higher pressure rating. J3 corrosion protection is now included(240 hour salt spray test according to EN ISO 9227).
l Sizes 08 to 30
l Leak-free isolation in one direction
l In-line connection
