What measures should industrial enterprises take to prevent electric shock in production safety?

What measures should industrial enterprises take to prevent electric shock in production safety? First, strengthen the education of electrical safety technology for employees, improve the safety operation skills of full-time electrical personnel, strictly implement electrical safety regulations, and prevent misoperation; It is forbidden for part-time electrical personnel to stop or send electricity; Increase workers' common sense of power safety and enhance their ability to prevent accidents.

Two, strengthen the safe use and management of electrical equipment and devices. Install protective grounding device and zero connection device in power grid lines; Distribution transformer should adopt neutral point insulation system and install leakage protection device; Lighting, communication, signals, etc. Easy to cause electric shock danger, should use 127V or safe voltage power supply; Strengthen the isolation protection of * * * conductors and dangerous equipment; It is forbidden to overhaul or move equipment online. And regularly maintain electrical equipment and safety devices to make them in good condition.

Three, strengthen the safety management and inspection of electricity. The erection of power lines shall comply with electrical safety regulations, and high-voltage cables and wires shall not be scattered in muddy water. Cables, wire connectors and bare wires that do not meet the requirements should be rectified in time. It is strictly forbidden to use electricity illegally.

Four, strengthen the management of electrical safety technical preventive measures

Strengthening management and improving the safety skills of operators and strengthening the maintenance and inspection of equipment can reduce accidents, but can't put an end to electric shock accidents, because the damage and leakage of electrical equipment occur randomly. When the shell of electrical equipment is charged due to insulation damage, there is no sign of charging, so people will not have any premonition of the danger of electric shock. At this time, it is often prone to electric shock accidents, and it is difficult for operators to operate in full accordance with the rules. Strengthening technical prevention is a good way to reduce accidents, and many electric shock accidents can still be avoided.

1, protective grounding

Its function is that when the metal shell of electrical equipment is charged, if the human body touches the shell, because the resistance of the human body is much greater than that of the grounding body, most of the current flows into the earth through the grounding body, while the current flowing through the human body is very small. At this time, as long as the grounding resistance is well controlled, the occurrence of electric shock accidents can be reduced. However, in TT power supply system, the equipment shell voltage of this protection mode is still quite dangerous to human body. Therefore, this protection method is only applicable to the construction site of TT power supply system, and the grounding resistance is not more than 4Ω according to regulations.

2, protection by zero

Its function is that when the metal shell of electrical equipment is charged, the short-circuit current becomes a closed circuit through the zero line, making it a single-phase short-circuit fault. Because the neutral impedance is very small, the short-circuit current is very large, which is usually several times or even dozens of times larger than the rated current. Such a large single-phase short circuit will make the protection device act quickly and accurately, cut off the emergency power supply and ensure personal safety. Its power supply system is a zero protection system, namely TN system. Whether the protective zero line is separated from the working zero line, TN power supply system can be divided into TN-C, TN-S and TN-C-S.

No matter whether protective grounding or protective zero connection is adopted, it must be noted that in the same system, it is not allowed to ground some equipment and connect other equipment to zero. Because in the same system, if some equipment is grounded and some equipment is connected to zero, when the grounded equipment collides with the shell, the neutral potential will rise, which will bring dangerous voltage to all equipment shells connected to zero.

3, set the leakage protector

First, the main distribution box and switch box should be equipped with at least two levels of leakage protectors, and the rated leakage action current and rated leakage action time of the two levels of leakage protectors should be reasonably matched to make them have the function of classified protection; Second, the switch box must be equipped with a leakage protector, and all electrical equipment on the construction site must be installed at the head end of the equipment load line in addition to the protection connection; Three, the leakage protector should be installed on the load side of the distribution box power disconnector and the load side of the switch box power disconnector; Fourthly, the selection of leakage protector should meet the national standards.

4. safe voltage

In workplaces where safe voltage can be used, try to use safe voltage. When the electrical device uses more than 24V, protective measures must be taken to prevent direct contact with charged bodies.

Five, strengthen the professional management measures of electrical safety, can refer to the relevant national electrical safety organization measures and electrical safety technical measures related content requirements.

Emergency measures for safety production in chemical enterprises All enterprises have emergency plans, so you can refer to the emergency plans of this industry!

The drill corresponding to the emergency plan is the corresponding strategy for sudden and unexpected situations, as well as the deployment requirements of personnel and facilities.

What measures should be taken to avoid mistakes in enterprise safety production? The main measures to prevent safety accidents are as follows:

(1) Implement safety responsibility and responsibility management.

Establish and improve the leading organization of production safety with the project manager as the first responsible person, and assume the responsibility of organization and leadership of production safety; Establish the responsibility system for production safety of personnel at all levels, clarify the safety responsibilities of personnel at all levels, and pay attention to the implementation of responsibilities and systems. (2) Safety education and training

Management and operation personnel should have the basic conditions and quality of safe production; After safety education and training, only after passing the examination can they work at their posts; Personnel engaged in special operations (electrician operation, hoisting machinery operation, electric welding operation, climbing erection operation, etc.). ) Only after receiving special training, passing the examination and obtaining a special operation certificate can special operations be carried out independently.

(3) Safety inspection

Safety inspection is an important way to find hazards, eliminate hidden dangers of accidents, prevent accidents and improve working conditions.

(4) Work standardization

It is an effective measure to control people's unsafe behavior and prevent safety accidents to standardize the behavior of workers in various positions and types of work according to scientific operating standards.

(5) the unity of production technology and safety technology

The unity of production technology and safety technology embodies the management principle of "managing production and safety" and the implementation of the responsibility system for safety production on the same basic point of ensuring smooth production and realizing benefits.

(6) Civilized construction management on the construction site

Civilized construction management in the construction site is an important content to eliminate dangerous sources and prevent safety accidents. On-site civilized construction management includes four contents: on-site management (including on-site safety management), material management, environmental protection management and health management.

(7) Correctly treat the investigation and handling of accidents.

A safety accident is an unexpected event against people's will. Once a safety accident happens, we should protect the scene and rescue the wounded with a serious, earnest, scientific and positive attitude, then analyze the reasons and formulate measures to avoid similar accidents.
