What is my country’s eight-character policy for dust prevention and reduction?

Eight-character policy. "Le, water, density, wind, protection, management, teaching, inspection"

Ge means technological innovation.

Reforming the process and production equipment so that no or less dust is generated during the production process and replacing high-toxic dust with low-toxic dust are fundamental measures to prevent dust hazards.

Specific measures are mainly reflected in the mechanization, piping, sealing, automation and remote operation of the production process in dust workplaces in various industries.

Water means wet operation.

Using wet operations to reduce the generation and spread of dust in the workplace is an economical and effective dust prevention measure. Measures such as rock drilling, water-type electric coal drills, coal seam water injection, blasting spray, loading rock slag with water, and rock flushing are promoted in mining enterprises.

Dense means sealing the source of dust. For places where wet operations cannot be carried out, closed ventilation and dust removal methods should be adopted. If a closed dust source is combined with a local exhaust fan to maintain a certain negative pressure in the closed system, it can effectively prevent dust from escaping.

Wind means ventilation and dust removal.

Ventilation and dust removal is a dust removal method that uses reasonable ventilation to dilute and discharge dust in the air in the workplace. In the mining system, although corresponding dust prevention and reduction measures have been adopted in each major dust-producing process, there is still a part of dust, especially respiratory dust, suspended in the air that is difficult to settle. In this case, ventilation and dust removal are very effective dust removal methods.

Protection means personal protection.

For situations where the dust concentration in the workplace cannot be reduced below the national health standards even after taking certain measures, or when dust-proof facilities fail, etc., wearing dust-proof masks for workers exposed to dust is still a good solution. . But currently, mining companies still have some problems in wearing dust masks for workers. First, some mining companies did not distribute dust masks to workers as required; second, although dust masks were distributed to workers, the quantity was insufficient; third, workers were unwilling to wear the dust masks distributed due to poor product quality. . In response to these situations, the author believes that for workplaces that do not meet the national dust hygiene standards, in addition to actively taking measures to control dust, dust-proof masks of qualified quality and sufficient quantity should also be equipped for dust-exposed personnel to reduce the harm of dust to workers' health. . Enterprises that produce and operate dust masks should provide users with high-quality and low-price products in accordance with national standards and specifications to meet the needs of the market. In addition, the product standards and product testing and inspection specifications for dust masks currently in use in our country are also relatively backward. New dust mask product standards and testing specifications should be revised and promulgated as soon as possible to meet the needs of my country's economic development and occupational disease prevention and control.

Management means strengthening management.

It is necessary to conscientiously implement laws and regulations such as the "Law on the Prevention and Control of Occupational Diseases" and the "Safety Production Law", establish and improve dust prevention rules and regulations, and regularly monitor the concentration of dust in the air in the workplace. The person in charge of the employer shall be directly responsible for the prevention and control of pneumoconiosis in the unit. Measures should be taken not only to make the dust concentration in the workplace of the unit meet the national health standards, but also to establish and improve the dust monitoring, safety inspection, and regular health monitoring systems; to strengthen the management of treatment, recuperation, and occupational health publicity and education for pneumoconiosis patients. .

Investigation means strengthening the health examination of workers exposed to dust, monitoring the dust concentration in the workplace, and supervising and inspecting the prevention and control of pneumoconiosis by regulatory departments and safety supervision agencies at all levels.

Recently, the state has adjusted the supervision and management responsibilities of occupational health in the workplace. The supervision and management of occupational health in the workplace has been changed from the Ministry of Health to the State Administration of Work Safety. The supervision and management of occupational health in coal mine workplaces are implemented by coal mine safety supervision agencies at all levels.

Teaching means publicity and education.

The enterprise's production safety management personnel and dust-exposed workers should be trained and educated on laws and regulations on occupational disease prevention and control, and understand the basic knowledge of production dust and pneumoconiosis prevention and control, so that workers can realize that pneumoconiosis is 100% Pneumoconiosis can be prevented, as long as dust prevention and dust reduction work are done well, pneumoconiosis can be eliminated.
