It can be summarized as the eight-character policy of "leather, water, density, wind, protection, management, education, and investigation". “Gege” refers to the reform of backward production process equipment and technical measures to fundamentally eliminate the hazards of dust; “water” refers to the use of wet operations to prevent dust from flying; to prevent dust from entering the air; “wind” refers to strengthening ventilation in the workplace to Dust is extracted from the site to reduce the concentration below the allowable concentration of national standards; "protection" means strengthening personal protection, using dust masks, air supply helmets, etc. that meet national standards to protect workers; "management" means strengthening management and establishing a complete and effective The management system and necessary measures as well as the maintenance and repair system of dust-proof equipment; "teaching" means providing necessary occupational health education and dust-proof education to workers; "checking" means implementing the pre-employment and regular physical examination system for workers working in dust operations.
How to clean dust: The protective effect of protective masks depends on two aspects. One is the filtration efficiency of the filter cotton. The second is the tightness of the combination of the mask and the face.
Scientific selection of protective masks certified by the GB2626-2006 standard can help prevent lung damage.
1. Choose the duplex half mask type. Disposable masks are not suitable for long-term protection due to their high air leakage rate.
2. Choose KP100 grade filter cotton. Low protection rates will result in physical harm.
3. It is more comfortable to choose silicone material. Suitable for long-term wear and unlikely to cause allergic reactions. Masks with high hardness can easily cause facial indentations.
4. Masks are divided into large and small sizes, which is extremely important. Don’t buy those so-called universal masks. Easy to leak.
5. There are two types of masks: covering the mouth and nose, and covering the mouth, nose, and chin. It is recommended to use the latter, which is relatively more comfortable.
6. It is recommended to choose a smooth breathing mask. Some masks are designed with double filter cotton, and the filter cotton has two sides. Such masks make breathing relatively smooth.
