Measures: (1) Organizational measures: In accordance with the regulations, not only local authorities, but also the competent departments in charge of enterprises and institutions, as well as the leaders of factories and mines, should attach great importance to the prevention and control of pneumoconiosis. Organizational leadership for this work is necessary, and it should be integrated into economic development plans; moreover, dedicated personnel should be assigned to carry out this work. The persons in charge of enterprises and institutions bear direct responsibility for the prevention and control of pneumoconiosis in their respective organizations. They should take measures to ensure that dust concentrations in the work areas meet **health standards**, and they must establish comprehensive systems for dust monitoring, safety inspections, and regular health checks. Additionally, they need to improve the handling of patients with pneumoconiosis, as well as efforts related to their rehabilitation and education. (II) Technical measures: Adopting comprehensive measures such as leather protection, water control, sealing, wind prevention, and protection to carry out dust suppression is the most fundamental preventive measure against pneumoconiosis. 1. Reforming the technological process and upgrading production equipment, that is, \"reform,\" is the fundamental way to eliminate dust hazards. Methods such as remote control, computer-based control, and compartmental monitoring are used to avoid contact with dust ； Use wind transportation and negative pressure sand suction to reduce dust emission ； Another example is using limestone with low quartz content to replace quartz sand as the molding material, in order to reduce the hazards of dust. 2. Wet methods of work are an economical, simple, and practical dust control measure. If wet grinding of quartz and refractory material raw materials is used ； Operations such as wet drilling in mines, mist spraying for underground transportation, and high-pressure water injection into coal seams can basically prevent dust from rising and reduce environmental dust concentrations. 3. Sealing, ventilation, and dust removal. For areas where wet methods cannot be used, enclosed ventilation and dust removal methods should be employed. If a combination of enclosed dust drying and local exhaust ventilation is used, it prevents dust from escaping. The dust-laden air drawn in is further treated by a dust removal device before being released into the atmosphere. (III) Health care measures 1. Health examinations for workers exposed to dust: In accordance with the \"Regulations on Medical Prevention Measures for Workers in Dusty Environments,\" workers engaged in dust-related work must undergo pre-employment and regular health examinations; some of them also need to have examinations to assess their exposure to dust. (1) Pre-employment examination ； Workers who are about to engage in dust-exposed work (including those preparing for a shift to such work) must undergo a pre-employment examination. The items to be checked include occupational history ； Subjective symptoms and past medical history ； History of exposure to tuberculosis ； General clinical examination ； Take chest X-rays and any other necessary tests. Those under 18 years of age and those suffering from the following diseases are not allowed to engage in dust-exposed work: ① Active tuberculosis ； ②Severe chronic upper respiratory and bronchial diseases, such as atrophic rhinitis, nasal tumors, bronchial asthma, bronchiectasis, and chronic bronchitis ； ③Thoracic diseases that significantly affect lung function, such as diffuse pulmonary fibrosis, emphysema, severe pleural thickening and adhesions, and thoracic deformities ； ④Severe cardiovascular diseases. (2) Regular examinations: The purpose is to detect patients with pneumoconiosis in a timely manner and monitor changes in their condition. The inspection interval is determined by the local health authorities depending on the specific circumstances. As a general rule, those with high levels of exposure are inspected every 1–2 years, those with lower levels of exposure are inspected every 2–3 years, and in some cases inspections can be carried out every 3–5 years. For employees who are no longer exposed to dust, the inspection interval can be determined based on the specific characteristics of the dust they were exposed to ； Patients with pneumoconiosis generally undergo follow-up examinations once a year; this interval may be shortened or extended as appropriate depending on the progression of the disease ； Those diagnosed as O+ should have a follow-up examination once a year. The physical examination should include a work history, subjective symptoms, and a frontal chest X-ray. Workers found to have diseases that make it unsuitable for them to continue working in dust-exposed environments should be transferred from such roles promptly. Dust removal operation inspection. Employees who are transferred away from dust-exposed jobs for any reason should, before leaving such jobs, undergo a health examination as much as possible, have their occupational history recorded, and have chest X-rays taken. Its purpose is not only to understand the health status during dust exposure but also to maintain records for future follow-up to determine whether late-onset pneumoconiosis occurs. Standards: GB/T5817-2009 \"Classification of Hazard Levels in Dusty Workplaces\", \"Hygienic Standards for Industrial Enterprise Design\" (TJ36-79)

1. Add mist spray； 2. Provide employees with appropriate dust protection equipment; not very familiar with the relevant standards

First, there must be dust removal facilities, and then there is the provision of personal protective equipment for employees...

Employees should wear dust masks, respirators (and gas masks as well for certain toxic dusts); properly don protective clothing (some also require coveralls with hoods), helmets (as the head is an area with a high concentration of sweat glands, sebaceous glands, and hair follicles), glasses, etc. Thirdly, eating, smoking, drinking water, etc. is prohibited in areas where dust is present.

In the workplace, workers should take protective measures in strict accordance with the given instructions and warnings, and wear dust masks in areas where dust is present. Occupational Health Management System and Job-Specific Operational Procedures (Revised Edition 2016), Article 74: The Safety Supervision Department is responsible for supervising and inspecting the protective measures in place for workers in areas where occupational disease hazards exist; workers shall provide support and cooperation in this regard, and must not refuse or obstruct such efforts. Article 75 Workers shall receive training on the regulations regarding notification and warnings about occupational disease hazards in the workplace, so as to understand and identify the meaning of warning signs and the appropriate response measures. Article 76: In workplaces where there are occupational hazards such as dust, radioactive substances, and other toxic and harmful substances, corresponding warning signs must be installed. Article 77: 1. Prohibition signs: Graphic and textual symbols that prevent unsafe behaviors ； 2. Warning signs: Graphic and textual symbols that alert people to the surrounding environment in order to avoid potential hazards ； 3. Instruction symbol: Graphic or textual symbols indicating that a certain action must be taken or protective measures must be applied ； 4. Indicator symbols: Graphic and textual symbols that provide certain information (such as indicating safety facilities or locations, etc.) ； 5. Warning lines: Strips used to indicate control areas, supervision areas in the workplace, or zones designated for rescue operations at accident sites. Article 78: Basic forms of warning signs. Warning signs are divided into prohibition signs, warning signs, instruction signs, guidance signs, and alerts. 1. The basic form of a prohibition sign is a red circle with a slash ； 2.

Article 79 Signs and Markings ； 1. In workplaces where dust that can cause pneumoconiosis is present, install warning signs stating “Be careful of dust” ； 25 In workplaces with occupational disease hazards, warning signs shall be installed in prominent locations in accordance with the following provisions. 2.
