Inhaling too much metal dust is generally easy to cause metal deposition, and oxidized metal dust is easy to suffer from pneumoconiosis.
Pay attention to occupational health protection when working in the above places with high dust concentration. Mainly based on respiratory protection. You need to choose a dust mask correctly.
1, dust mask must pass the certification of GB2626-2006, which belongs to special labor protection.
2, dust mask N90, N95, N 100 three levels. Among them, the protection rate of N 100 is higher. N 100 should be selected to prevent pneumoconiosis.
3. According to national standards, dust masks come in three sizes: large, medium and small. Choose the appropriate size, and the sealing effect is good.
4. Try to choose breathable ones. At present, the mask adopts the principle of electrostatic adsorption, and the respiratory resistance will not be too great. Some manufacturers use double-sided and double-piece design, and basically do not feel respiratory resistance.
5. Try to choose a long-lasting cotton filter element. Long-term cotton filtration has low respiratory resistance, and some cotton filters can be used for nearly a month. The average daily cost is one yuan. Such masks are easily accepted by the public.
So for the happiness of yourself and your family, you must pay attention to occupational health protection in your environment.
