1. Are there any instances of \"three violations\" at the production site? The \"three violations\" refer to giving illegal instructions, performing operations in violation of regulations, and breaking labor discipline. Pay special attention to whether employees follow the safety procedures during on-site operations and wear appropriate personal protective equipment. There are different regulations regarding the provision and use of personal protective equipment for workers in various industries. For example, construction workers need to be equipped with and use safety helmets, work uniforms, work shoes, gloves, etc.; those who work in crushing operations should primarily use dust and gas masks, while machinists and machine operators need to wear protective leather shoes and safety glasses. Are the environments in Workshop 2 and the warehouse tidy, and are the materials stored in an orderly manner? Oxygen cylinders and acetylene cylinders must not be exposed to direct sunlight or placed upside down; these two types of cylinders should not be stored together (in a well-ventilated and spacious area, they can be stored at a distance of 5 meters apart). 3. Is the management of hazardous materials proper? Is the handling of highly toxic substances and explosives carried out in accordance with the \"five doubles\" principle? Are hazardous chemicals stored in dedicated areas? Do they come equipped with safety data sheets and safety labels? 4. Whether safety devices and warning signs are installed on key projects and critical equipment and facilities. 5. Whether work involving open flames has been approved and whether effective protective measures have been taken; in particular, whether the “Six Prohibitions,” “Five Conditions Under Which Open Flames Are Not Permitted,” and “Ten Rules Against Burning” are being followed. 6 Have safety precautions been taken for hazardous tasks such as working at heights and in confined spaces? For example, have construction plans and safety operating procedures been established, safety measures implemented, and safe areas designated at the work site? ； To be carried out by qualified units and professionals ； Designate a specific person to provide unified on-site command ； There are safety management personnel to carry out on-site supervision, etc. 7. Are the facilities in the workshop, warehouse, and employee dormitories in compliance with safety requirements? 8. Do the workshop and employee dormitories have safety exits and evacuation routes as required, and are fire-fighting equipment and facilities installed in accordance with regulations? 1. A factory building should generally have no fewer than 2 safety exits ； However, one can be installed if the following conditions are met: (1) The floor area of Class A factories does not exceed 100 m², and the number of workers present at any given time does not exceed 5. (2) The floor area of Class B factories shall not exceed 150 m², and the number of workers present at any given time shall not exceed 10. (3) The floor area of Class C factories shall not exceed 250 m², and the number of workers present at any given time shall not exceed 20. (4) For Class D and Class E factories, the floor area per floor shall not exceed 400 m², and the number of workers present at any given time shall not exceed 30. 2. The evacuation routes in the factory building include stairs, corridors, and doors: the width of evacuation stairs should be at least 1.1 m, the width of corridors should be at least 1.4 m, and the width of evacuation doors should be at least 0.9 m; these doors must open outward. (When the number of people is less than 50, the requirements can be slightly reduced, but the door width must still be at least 0.8 m.) Emergency lighting and evacuation indicator lights should be installed on stairs and corridors. 3. Fire-fighting equipment: It is mainly necessary to ensure that fire extinguishers are provided in accordance with the risk level of the business premises. When selecting fire extinguishers, it is necessary to choose them based on the nature of the enterprise’s operations. For example, in petrochemical facilities, foam or ABC dry powder fire extinguishers should be used, while for precision instruments, gas-based fire extinguishers (such as carbon dioxide or halon-based ones) are appropriate; in other cases, ABC dry powder fire extinguishers are a good choice. The standards for fire extinguisher placement are as follows: Location name, Location category, Area in square meters, Number of extinguishers required. For factories: Category A – 25 square meters, 1 extinguisher; Category B – 25 square meters, 1 extinguisher; Category C – 30 square meters, 1 extinguisher; Category D – 50 square meters, 1 extinguisher; Category E – 50 square meters, 1 extinguisher. For warehouses: Category A – 30 square meters, 1 extinguisher; Category B – 30 square meters, 1 extinguisher; Category C – 50 square meters, 1 extinguisher; Category D – 50 square meters, 1 extinguisher; Category E – 50 square meters, 1 extinguisher. For power distribution rooms – 10 square meters, 1 extinguisher. 9. Is natural ventilation and dust removal sufficient? In workshops where minor amounts of heat, steam, smoke, or dust are generated during production, is natural ventilation achieved through doors and windows? ； In more serious workshops, is mechanical ventilation used to remove harmful substances? 10. Whether the electrical equipment and its installation comply with industry standards and safety requirements; electrical equipment includes devices for power generation, transformation, transmission, or consumption. 1. For power transmission and distribution lines: in Class A factories and warehouses, as well as for Class A and B liquid and gas storage tanks, the minimum horizontal distance from these structures to overhead power lines should be 1.5 times the height of the utility poles; for Class C liquid storage tanks, this distance should be at least 1.2 times the height of the utility poles. Wires in the factory building must not be connected haphazardly, and iron or copper wires cannot be used as fuses. 2. When the length of the power distribution room is greater than 7 m and its floor area is greater than 60 m, 2 exits should be provided ； The door of the power distribution room should open outward ； The windows of the power distribution room should be fitted with measures to prevent rain, snow, and small animals from entering. 3. Electrical equipment must be grounded. 4. Electrical equipment such as switches and lighting in places where hazardous materials are produced or stored should be equipped with explosion-proof devices; wires should be protected by non-flammable conduits, and incandescent lamps in warehouses should have a power rating of 60 watts or less (the use of ordinary fluorescent lamps is strictly prohibited). 11. Do special equipment items have valid safety operation certificates? The use of special equipment such as boilers, pressure vessels, elevators, and lifting machinery requires registration and inspection by the quality and technical supervision authorities, and a operation certificate must be obtained. 12. Are effective monitoring measures in place for the 12 major hazard sources? 13. Have the relevant safety regulations and standard operating procedures been properly implemented? 14. Other aspects that need to be checked. 1. Has the construction project undergone the “three simultaneities” review for work safety? According to the regulations, construction projects that require a review under the \"three simultaneities\" principle for safe production include: first, mining construction projects; second, construction projects used for the production or storage of hazardous materials; third, construction projects in high-risk industries that involve the use of hazardous chemicals; fourth, construction projects that fall within the scope of supervision and management of major hazard sources; fifth, construction projects with fire and explosion risks; sixth, construction projects that have a significant impact on the local economy; seventh, construction projects for which there are separate regulations in specific fields or industries; eighth, other construction projects identified by the safety production supervision and management authorities as having high levels of risk. The review steps are divided into preliminary design review and completion acceptance review. 2. Have high-risk enterprises conducted safety assessments in accordance with regulations? This refers to entities involved in the production and storage of hazardous materials, as well as those engaged in the production, storage, operation, and use of such chemicals; high-risk industries such as mines and fireworks manufacturers; and enterprises that possess major hazard sources. These entities are required to conduct safety assessments in accordance with **relevant regulations. 3. Are employees working overtime? 4. Have any targeted inspections and corrective actions been carried out based on the production characteristics of the industry, such as the safety conditions in the polishing workshops of tannery companies, and whether high-risk enterprises have installed anti-static and lightning protection devices? 5. Whether the enterprise’s management personnel, safety officers, and workers engaged in special operations hold relevant certificates, and whether employees have received “three-level training”.
