The key to prevent pneumoconiosis is to prevent dust and prevent the inhalation of harmful dust to the maximum extent.
It can be summarized as the eight-character policy of "leather, water, density, wind, protection, management, teaching and inspection". "Reform" means reforming backward production technology and equipment and technical measures to fundamentally eliminate the harm of dust; "Water" refers to wet operation to prevent dust from flying; "Dense" means to prevent dust from entering the air through sealing; "Wind" is to strengthen the ventilation in the workplace, suck the dust away from the site, and reduce it to below the allowable concentration of national standards; "Protection" refers to strengthening personal protection and adopting dust masks and air supply helmets that meet national standards to protect workers; "Management" refers to strengthening management, establishing and improving effective management systems and necessary measures, and maintaining and repairing dust-proof equipment; "Teaching" is to provide necessary occupational health education and dust prevention education for workers; "Check" is to implement the system of pre-job and regular physical examination for dust workers.
The most important thing to prevent pneumoconiosis is the dust mask of workers. It is recommended to wear a dust mask with the highest national protection level KN 100.
