Legal analysis: Dust prevention measures are technical measures, organizational measures and medical preventive measures to prevent the harm of productive dust. Our comprehensive measures to prevent sand and reduce dust can be summarized as the eight-character policy of "skin, water, density, wind, protection, management, education and inspection", which has guiding significance for controlling dust hazards.

1, leather, that is, process reform and technological innovation, which is the fundamental way to eliminate dust hazards, often take the following objectives as the focus of reform. (1) Reduce the silicon content in raw materials, or replace them with materials without silicon. (2) Mechanization, continuity and automation of production to reduce dust sources. Create conditions for closed dust sources to adopt ventilation and dust removal measures. (3) Reduce manual labor and dust flying. (4) Reduce the contact between workers and powder.

2. Water, that is, wet operation, can prevent dust from flying and reduce the environmental dust concentration.

3, wind, strengthen ventilation and exhaust measures, on the basis of closed and semi-closed dust sources, use local extraction mechanical ventilation to extract the dusty air from the working face, and at the same time use local conveying mechanical ventilation to send fresh air to the working face.

4. Dense, seal the dust source, seal the equipment that produces dust in the ventilation hood as much as possible, combine with exhaust, and then discharge it into the atmosphere after dust removal.

5, protection, personal protection, is a supplement to the prevention and dust reduction measures, especially where technical measures failed to achieve. If wearing a dust mask, a dust helmet, an isolated compressed air respirator and a dust suit, use skin cream and skin cleaning liquid; Do not eat or smoke in the workplace, pay attention to personal hygiene; Put on work clothes and wash them thoroughly before going home. Be sure to wash your hands before eating food

6, tube, regular maintenance management.

7, teaching and educating people, strengthen publicity and education.

8, check, regularly check the dust in the ambient air and regular physical examination of contacts.

Legal basis: Article 21 of the Law of People's Republic of China (PRC) on the Prevention and Control of Occupational Diseases, the employer shall take the following measures for the prevention and control of occupational diseases:

(a) to set up or designate an occupational health management institution or organization, with full-time or part-time occupational health management personnel to be responsible for the prevention and control of occupational diseases in the unit;

(2) Formulating occupational disease prevention and control plans and implementation plans;

(three) to establish and improve the occupational health management system and operating procedures;

(four) to establish and improve the occupational health files and workers' health monitoring files;

(five) to establish and improve the monitoring and evaluation system of occupational hazard factors in the workplace;

(six) to establish and improve the emergency rescue plan for occupational disease hazards.
