Leather means technological innovation.
The fundamental measure to prevent dust hazard is to reform the technological process and production equipment, so that no or less dust is produced in the production process, and low-toxic dust is used instead of high-toxic dust.
The specific measures are mainly reflected in the mechanization, assembly line, sealing, automation and remote operation of the production process in dust workplaces in various industries.
Water, that is, wet work.
Wet operation is an economical and effective dust prevention measure to reduce the generation and diffusion of dust in the workplace. In mining enterprises, measures such as rock drilling, water-type electric coal drilling, coal seam water injection, blasting spray, rock slag spraying and rock slope washing are promoted.
Dense, that is, sealed dust source. For places where wet operation cannot be carried out, closed ventilation and dust removal should be adopted. If the closed dust source is combined with the local exhaust fan to keep a certain negative pressure in the closed system, dust can be effectively prevented from escaping.
Wind is ventilation and dust removal.
Ventilation and dust removal is a dust removal method that dilutes and discharges the dust in the workplace air through reasonable ventilation. In the mine system, although the main dust-producing processes have taken corresponding dust-proof and dust-reduction measures, some dust, especially respirable dust, is still suspended in the air and difficult to settle. In view of this situation, ventilation and dust removal is a very effective dust removal method.
Protection is personal protection.
If the dust concentration in the workplace can't be reduced below the national health standard after taking certain measures or the dust-proof facilities fail, it is still a good solution to wear dust masks for workers who come into contact with dust. However, there are still some problems for workers in mining enterprises to wear dust masks. First, some mining enterprises failed to issue dust masks to workers as required; Second, although dust masks were distributed to workers, the number was insufficient; Third, dust masks are issued. Because of the poor quality of the products, workers are unwilling to wear them. In view of these situations, the author thinks that for workplaces that do not meet the national dust hygiene standards, in addition to actively taking measures to control dust, dust workers should also be equipped with qualified and sufficient dust masks to reduce the harm of dust to their health. Enterprises that produce and operate dust masks shall, in accordance with the requirements of national standards and norms, provide users with high quality and low price products to meet the market demand. In addition, the product standards and inspection specifications of dust masks currently used in China are relatively backward, so new product standards and inspection specifications of dust masks should be revised and promulgated as soon as possible to meet the needs of China's economic development and occupational disease prevention and control.
Management is to strengthen management.
We should conscientiously implement the Law on the Prevention and Control of Occupational Diseases, the Law on Safety in Production and other laws and regulations, establish and improve dust-proof rules and regulations, and regularly monitor the dust concentration in the air of workplaces. The person in charge of the employing unit is directly responsible for the prevention and treatment of pneumoconiosis in this unit. We should not only take measures to make the dust concentration in the workplace of our unit meet the national health standards, but also establish and improve the system of dust monitoring, safety inspection and regular health monitoring; Strengthen the treatment, recuperation management and occupational health publicity and education of pneumoconiosis patients.
Check, that is, strengthen the health examination of workers exposed to dust, monitor the dust concentration in the workplace, and supervision departments and safety supervision institutions at all levels supervise and inspect the prevention and control of pneumoconiosis.
Recently, the state has adjusted the duty of supervision and management of occupational health in the workplace, from the former Ministry of Health to state administration of work safety. The supervision and management of occupational health in coal mine workplaces shall be implemented by coal mine safety supervision institutions at all levels.
Teaching is publicity and education.
Conduct training and education on occupational disease prevention and control laws and regulations for enterprise safety production management personnel and workers exposed to dust, understand the basic knowledge of prevention and control of productive dust and pneumoconiosis, and let workers realize that pneumoconiosis is 100% preventable, and pneumoconiosis can be eliminated as long as dust prevention and dust reduction are done well.
