1. When entering the construction site, you must first comply with the safety operation regulations and relevant rules and regulations.
2. All distribution boxes and switch boxes on the construction site should be inspected and repaired once a month. Workers must wear insulation when working, and must use electrician insulation tools.
3. When overhauling the distribution box and switch box, the relevant power supply must be disconnected or grounded, and the power failure sign must be hung, and live operation is strictly prohibited.
4. Sundries are not allowed to be placed in various electrical ideas.
5. When the fuse in various electrical boxes is replaced, it is strictly forbidden to replace it with melt that does not meet the relevant specifications. This will make the fuse not work well and cannot play a protective role.
6. Keep a sufficient safety distance between the wire and the ground and various facilities. <>
Pay attention to the connection between the electrical equipment and the protection zero line, in the early stage of many construction sites, many temporary power systems in the initial erection process are not arranged in accordance with the requirements of the zero line connection, the phenomenon of zero line connection is not tired, so that the equipment shell is electrified, so that workers are prone to electric shock accidents when working.
Pay attention to the leakage protector, the leakage protector is the most important protection and the last protection for electricity. There are still many workers at the construction site who are lucky and do not check the leakage protection as required. In this way, the leakage protection that produces the fault can not be found in time, and the leakage protector that produces the fault cannot play the role of safety protection.
Fire prevention measures for electricity on the construction site:
1. Correctly select the cross-section of the wire to prevent the overload of the line. Fundamentally prevent electrical fire.
2. Workers are easy to be tired in summer, and leaders such as contract foremen should carry out safety warnings and reminders in a timely manner, and ensure that all construction personnel pay attention to rest.
3. Keep a certain safety distance between the lamp and the flammable material at the construction site, and the light with too much power is not allowed to be used indoors, especially the bedside lamp is strictly prohibited, the bedside lamp is spotted, and it is easy to ignite the flammable items under the lamp. <>

Anonymous users2024-02-14First of all, the power should be turned off in time, and the power supply should be placed far away from the water, and secondly, a notice board should be set up in the place where the power supply is used, so as not to accidentally touch and cause electric shock.

Anonymous users2024-02-12Workers must wear safety helmets when entering the construction site, and they must wear insulated shoes when working electrically.
The power supply of electrical equipment should be erected and installed in accordance with the relevant regulations, and the construction should be "one machine, one gate, one box, and one leakage protection", and the electrical equipment must have good grounding and zero, and be equipped with reliable electric shock protection devices.
The on-site line must be neatly arranged according to the regulations, and it is not allowed to be dragged on the ground to prevent crushing; Signs are installed when buried underground. After the joint is bandaged according to the standard, it must be overhead or set up with a joint box and have waterproof measures, and all wires on the pile frame and chassis are strictly forbidden to have joints.
The distribution box shall be installed with a leakage protection switch, and there shall be rainproof measures, and the door shall be installed and locked.
The wiring of the power line and the electrical box is accurate, the insulation is reliable, the grounding is firm, the electric shock protector is sensitive and effective, and the power supply capacity and wire cross-section meet the requirements of the safety electricity specification.
The electrical box on the drilling rig is in good condition, the motor is grounded and connected to zero firmly and reliably, and the electric shock protector is sensitive. It is forbidden to start the motor with load, and it is strictly forbidden to operate it with your feet.
The cables used in the drilling rig should be checked regularly, and the joints must be tied firmly to ensure that they are impermeable, leakage-free and overhead.
The electrician can not operate with electricity when wiring, and should hang a warning sign of "strictly forbidden closing" at the closing place when dismantling and repairing, and send a special person to take care of it.
The power supply lines in the construction site should be overhead or trenched and buried, and the insulation of the electrical lines should meet the safety requirements.

Anonymous users2024-02-111. The metal shell of electrical equipment should be protected by grounding or zeroing.
2. Install an automatic power-off device with leakage protection function.
3. Use safe voltage as much as possible.
4. Ensure that the electrical equipment has good insulation performance.
5. Adopt electrical safety appliances.
6. Set up a screen protection device.
7. Ensure the safe distance between people or objects and charged bodies.
8. Regularly inspect electrical equipment.
Safety technical measures for electrical circuits:
1. All electrical circuits at the construction site are powered by the "three-phase five-wire system" (TN-S system) special protection zero (PE line) system.
2. The overhead line at the construction site adopts insulated copper wire.
3. Overhead lines are set up on special poles, and it is strictly forbidden to erect them on trees and scaffolding.
4. Keep a sufficient safety distance between the wire and the ground. The minimum vertical distance between the wire and the ground: the construction site should not be less than 4m; The motorway should not be less than 6m; The railway track should not be less than.
5. If the specified electrical safety distance cannot be guaranteed, protective measures must be taken.
1. Ignoring safety and grasping production is to take a chestnut from the fire, and seeking benefits from safety is like fishing for the moon in water. >>>More

At the construction site, you still have a lot of opportunities, but one thing is very necessary, you must be able to bear hardships and learn well, know how to persevere, just enter the construction site must start from a small worker, this is also the most bitter time, you must learn to be sweet and diligent, follow the master to learn technology, when you learn the master's technology, don't feel that the master is useless, the construction site is very important is the network, because everyone is familiar with each other to introduce the live, then you can exchange learning technology with another master, When there is a very important point, do not change the major, when you do the technology in this profession after learning, you will learn to learn the pre-settlement, first of all, you must learn to calculate the materials required for the project, the basic materials can be calculated accurately after the amount of engineering, find a training class to train the valuation, you don't need to be too shrewd, but you can't let others cheat on it, when you complete these accumulation, you can take a few workers to start a small job to be a small boss, slowly accumulate experience funds, In the end, you can become a real boss, this time is relatively long, at least more than 5 years, remember to embark on the road of the boss can not be inflated, or do not have to die on this road, must be pragmatic, do not listen to the exaggeration of others, especially the blind planning of the theoretical school.
Annoying, hard, no hope.
1. Annoying. The people working on the construction site are basically migrant workers at the bottom of the society, these people have low cultural quality, the accommodation conditions are very poor, and the dormitory of about 10 people is particularly crowded. Roommates come from all over the world, everyone's experience is different, their personalities are different, and their living habits are different, so there will be a lot of contradictions, and quarrels are inevitable. >>>More
