It is too useful to check the hidden troubles in the workshop from these 14 aspects.

1 Is there any “three violations” at the production site?


"Three violations" refers to violations of regulations, illegal operations, and violation of labor discipline.
Focus on the on-site operation of employees to operate and wear labor protection products in accordance with safe operating procedures. There are different regulations for the staffing and use of labor insurance products in different industries. For example, construction workers should equip and use helmets, overalls, work shoes, gloves, etc. The crushers should focus on the use and use of dust masks, fitters, machine tools, and Use protective leather shoes, protective glasses, etc.


2 Whether the workshop and warehouse environment are neat and tidy, and whether the materials are stacked in order


       For example, oxygen cylinders and acetylene bottles cannot be exposed to the sun and inverted. The two cylinders cannot be placed in the same stock (small places with good ventilation, which can be stacked 5 meters apart).


3 Whether the management of dangerous goods is regulated


       For example, whether the management of drugs and explosives is “five pairs”, whether hazardous chemicals are placed in stock, whether hazardous chemicals have safety technical specifications and safety labels.


4 Whether the key projects, key equipment and facilities are equipped with safety devices and safety warning signs



5 Whether the use of hot fire has been approved and effective protective measures are taken


       If the fire does comply with the "six bans", "five no fire", "ten not burn" and so on.


6 Whether there are safety precautions for dangerous operations such as high-altitude suspension and limited space operations


       For example, if the construction plan and safety operation procedures are formulated, safety precautions should be taken, and the safety area of ​​the operation site should be set up; the units and professionals with corresponding qualifications should be constructed; the special person should be assigned to conduct on-site unified command; and the safety production management personnel should conduct on-site supervision.

7 Whether the setting of workshop, warehouse and staff dormitory meets the safety requirements




8Whether the workshops and staff quarters set up safe exits and evacuation passages according to regulations, and whether the fire-fighting equipment facilities are set according to regulations


       1. The safety exit of the plant should generally be no less than 2; but one of the following requirements can be set:
(1) The construction area of ​​each floor of Class A plant shall not exceed 100m2, and the number of production at the same time shall not exceed 5 persons.
(2) The construction area of ​​each floor of Class B plant shall not exceed 150m2, and the number of production at the same time shall not exceed 10 persons.
(3) The construction area of ​​each floor of Class C plant shall not exceed 250m2, and the number of production at the same time shall not exceed 20 persons.
(4) The construction area of ​​each floor of Ding and E plant shall not exceed 400m2, and the number of production at the same time shall not exceed 30.
       2. Factory evacuation passages include stairs, walkways and doors:
The width of the evacuation stairs is not less than 1.1m, the width of the walkway is not less than 1.4m, the width of the evacuation door is not less than 0.9m and the door is to be opened outwards (when the number of people is less than 50, it can be appropriately reduced, but the width of the door Not less than 0.8m). Emergency lighting and evacuation lights should be installed on stairs and walkways.
       3. Fire equipment:
The main reason is to check the fire extinguisher according to the hazard level of the enterprise. When configuring the fire extinguisher, it should be selected according to the production nature of the enterprise. For example, the petrochemical site should be equipped with foam or ABC dry powder fire extinguisher. The precision instrument should be equipped with gas (carbon dioxide, halogenated alkane) fire extinguisher. Other places should be equipped with ABC dry powder fire extinguisher.
The fire extinguisher configuration standards are as follows:
Place name Site classification Square meter Number of configurations
Factory building Class A 25 1
Class B 25 1
Class C 30 1
Ding 50 1
Class E 50 1
Treasury Class A 30 1
Class B 30 1
Class C 50 1
Ding 50 1
Class E 50 1
Power distribution room 10 1


9 Whether ventilation and dust removal meet the requirements


       In the production process, there are workshops that generate trace amounts of heat, steam, smoke, and dust. Are there any natural ventilation and ventilation through doors and windows; whether the workshops with more serious use mechanical ventilation to eliminate harmful substances.

10 Electrical equipment and installation comply with industry standards and safety conditions, electrical equipment including power generation, transformation, transmission or electricity


       1. Transmission and distribution lines: Class A plant, warehouse, the latest horizontal distance between Class A and B liquid and gas storage tanks and power overhead lines is not less than 1.5 times the height of poles, and Class C liquid storage tanks are not less than 1.2 times the height of poles. . The wires in the factory building cannot be connected indiscriminately, and the wire and copper wire cannot be used instead of the fuse.
       2. When the length of the power distribution room is greater than 7m and the building area is greater than 60m, two exits shall be provided; the doors of the power distribution room shall be opened outward; the windows of the power distribution room shall adopt measures to prevent the entry of rain, snow and small animals.
       3. Electrical equipment should be grounded.
       4. Electrical equipment such as switches and lighting for the production and storage of dangerous goods should be equipped with explosion-proof devices. The wires should be protected by non-combustible pipes. The incandescent lamps in the warehouse should be below 60w (normal fluorescent lamps are strictly prohibited).

11 Does the special equipment have an effective safety certificate?


       The use of special equipment such as boilers, pressure vessels, elevators, lifting machinery, etc. must pass the registration, inspection and inspection of the quality and technical supervision department, and obtain the use certificate.


12 Whether there are effective monitoring measures for major hazards


13 Whether the safety rules and regulations and safety operating procedures are in place


14 other aspects that need to be checked


       1. Whether the construction project has undergone a “three simultaneous” review of safe production.
According to the regulations, the construction projects that require safe production of “three simultaneous” examinations include: first, mine construction projects, second, construction projects for the production and storage of dangerous goods, and third, construction projects using high-risk industries such as hazardous chemicals. It is a construction project within the scope of supervision and management of major hazard sources. The fifth is a construction project with fire and explosion hazard, the sixth is a construction project that has a great impact on the national and regional economy, and the seventh is a construction project otherwise stipulated by the state and industry. It is another construction project with more danger or higher degree of safety confirmed by the safety production supervision and management department. The steps of the review are divided into a preliminary design review and a completion acceptance review.
       2. Whether the high-risk enterprises have conducted safety assessments in accordance with regulations.
Refers to the production, storage and production, storage, operation and use of dangerous chemicals, high-risk enterprises such as mines, fireworks and firecrackers, as well as enterprises with major hazards, which must be evaluated in accordance with national regulations.
       3. Does the employee have overtime work?
       4. Whether it has carried out some targeted key inspections and rectification work according to the production characteristics of the industry, such as the safety status of the tannery of the tannery enterprise, and whether anti-static devices and lightning protection devices are installed in high-risk enterprises.
       5. Whether the company's responsible person, safety management personnel, and special operations personnel have been certified to work, and whether the employees have passed the “three-level training”.
