Main measures for dust prevention and control

Dust means solid particles that can be suspended in the air. The dust produced in industrial production is called industrial dust. If industrial dust is not controlled, it will damage the working environment, endanger the health of workers and damage the machinery and equipment, and pollute the atmosphere.

At present, the harmful effects of dust on humans, especially pneumoconiosis, have not been specifically treated. Therefore, prevention of production dust prevention focuses on prevention, and it is very important to strengthen labor protection management on dust operations. Labor protection management of dust operations should adopt the three-level protection principle:

The primary measures for primary prevention include: Integrated dust protection, ie, reform of production processes, production equipment, and the conversion of manual operations into mechanized, automated, closed, and remote control operations; use materials that contain no or low free silica, if possible. Instead of containing high silica free materials; use wet process as much as possible under the conditions required by the process; use personal dust-proof equipment for personal protection.

Regular testing means that the dust concentration of the operating environment is regularly tested so that the dust concentration of the operating environment is within the allowable range specified by the national standard.

The health examination is based on the relevant regulations of the state, and the workers shall be subject to a pre-employment health examination. The occupational contraindications, minors, and female employees shall not be allowed to work in taboos.

Promote the basic knowledge of education and dust prevention.

Strengthen maintenance The dust removal system must be maintained and managed so that the dust removal system is in good condition.

The measures for secondary prevention include the establishment of a dust-relief agency responsible for personnel, the formulation of dust-prevention plans and various rules and regulations; the employees who are newly engaged in dust operations must carry out health inspections; and the workers engaged in dust operations must perform health regularly. Check and found that employees who are not suitable for dust control work should be promptly transferred.

The main measures for tertiary prevention are: For employees who have been diagnosed with pneumoconiosis, they should be promptly transferred from their original job positions, arrange reasonable treatment or convalescence, and the social insurance treatment of patients should be handled in accordance with relevant state regulations.
