Production management
1. [Selection] Lifting operation is being carried out in a construction site, which is equipped with safety warning signs, and no unrelated personnel are allowed to enter. In the process of lifting operation, staff A broke the lifting rope, and the falling of the lifting weight happened to break into the irrelevant personnel B without authorization. After analysis, the breakage of the lifting rope was caused by the aging of the rope. The occurrence of the accident reflects the () in the accident-causing theory.

Main Viewpoints of System Security Theory
(1) Measures to avoid accidents have changed. From focusing only on the unsafe behavior of operators to improving the system reliability of objects to improve the security of complex systems. (2) There are risk factors in everything, and nothing is absolutely safe. Generally speaking, safety or danger is a subjective judgment. Hazard source refers to the potential risk factors that can cause accidents. Hazard refers to the possibility of personnel or material damage caused by a hazard source. (3) It is impossible to eradicate all hazards and hazards, which can reduce the risks from existing hazards. Compared with eliminating individual specific hazards, it is better to reduce the overall risk. (4) Because of the limited cognitive ability of human beings, they can not fully understand the hazards and their risks, and will produce new hazards. It is not possible to eradicate all sources of danger, but to transform them into acceptable ones as far as possible.
3. [Single election] Accident prevention should start with the elimination of minor injuries and non-injuries. This view is based on () in the following options.
A. System Security Theory
B. Theory of accidental release of energy
C. Heine's Principle of Theory
D. Casual chain theory of accidents

[Reference Answer] C [Answer Analysis] Heinrich's Law concludes that the proportion of casualties, minor injuries and no injuries in mechanical accidents is 1:29:300. There are a lot of minor injuries and non-injuries. Behind these minor injuries and non-injuries, there are the same causes as those causing serious injuries. Therefore, the prevention of accidents should start with the elimination of minor injuries and harmless accidents.
Laws and regulations
1. [Single election] The following statement about the level of effectiveness of safety production laws and regulations in China is correct ().
A. The Safety Production Law and Regulations on Safety Production Management of Construction Projects belong to the same level of legal effect in the legal system of safety production.
B. Safety production regulations can be divided into administrative regulations, departmental regulations and local administrative regulations of the State Council.
C. The legal status of safety production laws and regulations in special economic zones is higher than that of local safety production laws and regulations.
D. The Mine Safety Law is a comprehensive law in the field of mine safety production and a separate law in the whole field of mine safety production.

[Reference Answer]D
[Answer Analysis] The law is the superior law in the legal system of production safety, which occupies the highest level of the whole system. Its legal status and effectiveness are higher than those of the lower laws such as administrative regulations, local regulations, departmental regulations and local government regulations.
Safety production laws and regulations are divided into administrative regulations and local regulations.
The legal status and effectiveness of the safety production laws and regulations of special economic zones and those of national autonomous regions are the same as those of local safety production laws and regulations.
2. [Selection] The legal system of safety in production includes the Safety in Production Law, separate laws on safety in production, laws related to safety in production, administrative regulations on safety in production, departmental rules and regulations, etc. The following statements on the effectiveness of the law are correct ().
A. Departmental and local government regulations have the same effect
B. Administrative regulations and local laws are now equally effective
C. Local regulations and local government regulations have the same effect
D. Constitution and law have the highest legal effect

Article 89 The effectiveness of local laws and regulations is higher than that of local governments at the corresponding and lower levels. C error;
Article 91 Departmental rules shall have the same effect as those of local governments and shall be implemented within their respective jurisdictions. A Right.
3. The scope of application of the Safety Production Law has been clearly stipulated. The following statement about the scope of application of the Safety Production Law is correct.
A. If the relevant laws and administrative regulations have other provisions on the safety of offshore oil exploitation, the Safety Production Law shall not apply.
B. If the relevant laws and administrative regulations have other provisions on the safety of dangerous chemicals and mines, the Safety Production Law shall not apply.
C. Where relevant laws and administrative regulations provide otherwise for nuclear and radiation safety and the safety of special equipment, their provisions shall apply.

Where there are other provisions on aviation safety, nuclear and radiation safety and the safety of special equipment, their provisions shall apply.
Production Technology
1. [Selection] In a hot forging plant, facilities that do not need to be added are ().
Dust-proof facilities
B. Sound insulation facilities
C. Heating facilities
D. Cooling Facilities
Scroll to see the answer
_
[Reference Answer]C
In the forging process, there is high temperature, so heating facilities are not needed to increase the heating capacity.
2. [Radio] The following statement about electric shock is correct ().
A. When electric shocks are severe, they may cause life-threatening injuries.
B. The degree of electric shock damage to human body is only related to the type and size of electric current.
C. When the current flowing through the human body is 50 mA, it will cause ventricular fibrillation current.
D. Men are more sensitive to electricity than women
Scroll to see the answer
_
According to item A and item B, the degree of harm caused by electric current to human body is related to the size, type, duration, route and condition of human body. C term, ventricular fibrillation current and current duration are closely related. When the duration of the current exceeds the cardiac cycle, the ventricular fibrillation current is only about 50 mA; in terms of D, the average (probability 50%) is about 16 mA for men; in terms of 10.5 mA for women; in terms of the minimum (probability 99.5%), it is about 9 mA for men; and in terms of 6 mA for women.
3. [Selection] The following dielectrics belong to liquid insulating materials are ().
