High dust practitioners, scientific selection of dust masks can effectively prevent the occurrence of pneumoconiosis.
Now the common dust mask itself is divided into high school and low protection level. High-quality dust masks are made of silicone. The breathing is smooth, the protective effect is good, and generally not stuffy. Currently there are domestic KN100 level masks on the use of double-sided, double-piece multi-layer filtration technology, good protective effect, and not hot and stuffy, smooth breathing. You can take a look at the e-commerce platform.
The way to clear the dust: in order to effectively prevent the occurrence of pneumoconiosis, coal mines and other dusty work environments, it is recommended to wear masks that meet the GB2626-2006 standard. These masks are generally labeled with a grade. According to the different protective effects, there are three grades: KN100, KN95 and KN90. The numbers represent the percentage of protection against ultra-fine dust.
1, the protective effect of the dust mask depends on the mask and the face of the closeness of the filter cotton protection level. If you work in a high dust environment, it is recommended to wear a KN100 grade dust mask.
2, it is recommended to wear a mask of size. Easy to enhance the protective effect. Currently, silicone material is common and relatively comfortable.
3, long-term wear, large physical expenditure of the environment, it is recommended to choose a smooth breathing mask. Some masks use double-piece, double-sided design, breathing is very smooth.
4, most of the disposable masks are not divided into size, in the national standard for its maximum air leakage rate allowable limit of 10%. Therefore, the compound half mask type dust mask is more suitable for occupational protection.
Scientific selection of dust masks can effectively prevent pneumoconiosis. At present, KN100 grade dust masks cost about 360 yuan per person per year for protection, and the enterprise has smooth breathing, good protection effect and low protection cost.
