Fill-in-the-blank questions 1. When using the analogy method for the preliminary assessment of occupational disease hazards, it is necessary to explain the comparability between the project under consideration and the analogous projects, including similarities in aspects such as natural environmental conditions, production processes, production equipment, occupational disease prevention measures, and management levels. 2. Employers exposed to occupational disease hazards shall entrust a vocational health technology service institution with the appropriate qualifications to conduct tests for occupational disease hazard factors at least once a year; employers facing severe occupational disease hazards shall, in addition to complying with the provisions of the preceding paragraph, also entrust such an institution to carry out assessments of the current status of those hazards at least once every three years. 3. Employers who carry out operations involving highly toxic substances shall conduct tests for occupational poisoning hazards in such workplaces at least once a month; they shall also evaluate the effectiveness of measures taken to control those hazards at least once every six months. 4. Harmful factors in the workplace include low oxygen levels or toxic gases; when their concentrations are high enough to be life-threatening, protective equipment such as isolated air respirators or oxygen respirators should be used. It is mentioned in the literature on the \"Standards for the Selection of Occupational Protective Equipment in Enterprises\". 5. For construction projects involving new construction, expansion, or renovation, as well as projects for technological upgrading or the introduction of new technologies, that may pose risks of occupational diseases, the project owner shall submit a pre-assessment report on such occupational disease risks to the department in charge of work safety supervision and management during the feasibility study phase. 6. The effectiveness of general ventilation depends on two factors: the volume of air exchange and the airflow pattern within the workshop. 7. The Maximum Allowable Concentration (MAC) is the highest permissible exposure limit established for chemical substances that have significant irritant, asphyxiating, or central nervous system depressant effects and can cause severe acute damage. 8. In general, harmful factors in the production process include chemical factors, physical factors, and biological factors. 9. For construction projects with serious occupational disease hazards, the pre-assessment report on such hazards must be submitted to the work safety supervision and management department for review; the design of the occupational disease prevention facilities must also be submitted to this department for examination. After the completion of the occupational disease prevention facilities, the work safety supervision and management department is responsible for organizing the acceptance process. 10. When the exposure concentration exceeds the PC-TWA and reaches the PC-STEL level, the continuous exposure time per session should not exceed 15 minutes, the number of exposures per workday should not exceed 4 times, and the interval between successive exposures should be no less than 60 minutes. 11. After a construction project is completed and requires trial operation, the occupational disease prevention facilities installed as part of it must be put into trial operation simultaneously with the main structure of the project. The trial operation period shall be no less than 30 days and shall not exceed 180 days, **except in industries where other regulations by relevant authorities or special requirements apply. . 12. The project owner is the entity responsible for the installation of occupational disease prevention facilities in construction projects; the project owner shall organize relevant experts to review the pre-evaluation report and be accountable for its accuracy and legality. 13. Role of occupational health technology service institutions: First, to provide technical support to **regulatory authorities; second, to offer technical services to employers; third, to provide health services to workers. 14. The occupational exposure limits for chemical hazards include three categories: time-weighted average permissible concentration, short-term exposure permissible concentration, and maximum permissible concentration. 15. Bag filters belong to the category of filter-type dust collectors. 16. The first level of the three-level prevention principle in occupational health is etiological prevention (eliminating and controlling occupational disease hazards at their root). 17. The costs associated with the installation of occupational disease prevention facilities for construction projects should be included in the project’s budget. Such facilities shall be designed simultaneously with the main structure of the project, constructed at the same time, and put into use once the project is completed. 18. Different occupational hazard factors cause varying degrees of harm to the human body. For example, dust can cause pneumoconiosis, chemical agents can lead to occupational poisoning, and noise can result in occupational deafness. 19. In the notes column for \"Permissible Concentrations of Chemical Substances in the Workplace,\" the terms \"Skin\" and \"G1\" are indicated. \"Skin\" refers to the possibility of systemic effects occurring through absorption across the intact skin as a result of direct contact with vapors, liquids, and solids via the skin, mucous membranes, and eyes. “\"G1\" refers to a substance confirmed to be a human carcinogen. 20. Production and business operations entities shall strengthen the prevention and control of occupational hazards in the workplace, provide employees with working environments and conditions that comply with laws, regulations, rules, as well as **standards and industry standards**, and take effective measures to ensure the occupational health of employees.
