When entering the construction site, the safety helmet must be worn, and the safety belt must be worn when working above 2 meters; "Four noes" means not going to work after drinking, not smoking, not urinating anywhere, not shirtless, barefoot, and wearing slippers to work; "Care" refers to the care for the safety facilities and daily facilities in the construction site and living area.

2, special operations personnel, mechanical operators must undergo training, assessment, show certificates.

3, mechanical and electrical equipment operators must abide by the operating rules, it is forbidden to illegal operation and sit and rest on the machine.

4. The "Three Don't Hurts" on the construction site means: don't hurt yourself, don't hurt others, don't hurt others.

5, pay attention to self-protection in the process of construction, it is forbidden to take risks, illegal operation.

Second, the civilized construction

When entering the construction site, you must wear a safety helmet and fasten your hat belt. Smoking, defecation, etc. It is strictly forbidden to appear on the construction site. After work, the construction site must be cleaned up, and building materials and garbage should be cleaned up in time. Materials must be stacked in the specified location and neatly stacked. Ensure the civilized construction image of the construction site.

Three. sanitation

During the construction period, all construction team members should always take a bath and wash clothes and clean the dormitory every day. Garbage should be piled up in the designated place to establish a good construction and living environment.

Fourth, public security and fire prevention.

1, public security. Fighting and stealing are strictly prohibited on the construction site. Once such incidents are discovered, the parties or their teams will be severely punished or directly quit. Pay more attention to emotions and think twice before you act.

2. Fire prevention. Smoking is strictly prohibited on the construction site. Once found, it will be punished according to the project safety management reward and punishment regulations, especially in scaffolding, wooden sheds and other places prone to fire. No smoking in bed; Electricity, gas welding, cutting or other operations that use naked flame on the construction site can only be carried out after the hot work certificate is obtained from the Ministry of Security.

Five, electrician operation matters needing attention

1 Electrical work must undergo professional safety technical training and pass the examination. Non-electricians are strictly forbidden to engage in electrical work.

2 electrician operations, must wear insulated shoes, gloves, drunk are not allowed to operate.

3 All insulation and test tools shall be properly kept, prohibited from being used, and shall be inspected and calibrated regularly. Ensure correct and reliable grounding or zero connection. All grounding or zero points must ensure reliable electrical connection. PE protecting zero line must adopt green/yellow double-color line, strictly distinguish phase line from working zero line, and do not mix them.

4 The installation, installation, protection, use and maintenance of electrical equipment must meet the requirements of Technical Specification for Temporary Electricity Use on Construction Site (JGJ46-2005).

5. In the power system with neutral point directly grounded on the construction site, 1N-S zero protection must be adopted.

6 The uncharged metal shell, frame, components, pipes, metal console and metal pillar of the mobile iodine tungsten lamp of electrical equipment shall be protected and connected to zero.

7 Regularly and irregularly inspect and maintain the grounding, equipment insulation and leakage protection switches of temporary power utilization projects, eliminate hidden dangers in time when found, and establish inspection and maintenance records.

Six, welder operation considerations

1, strictly abide by the "ten don't burn" rule.

2. Before operation, check whether all tools, welding machines, power switches and lines are in good condition, the metal shell should be grounded safely and reliably, the inlet and outlet shields are complete, and the inlet and outlet ends should be welded with copper joints.

3, each welder should have a dedicated power control switch. The fuse capacity of the switch should be 0.5 times that of the 65438+ machine.

4, welding arc spark point must be with oxygen cylinders, calcium carbide barrels, acetylene bottles, wood, oil and other dangerous goods distance not less than 10 meters. The distance from the explosive is not less than 20 meters.

5. Acetylene bottles and oxygen cylinders should be equipped with safety backfire preventers, and rubber pipe joints must be fixed with rolling heads.

6, oxygen cylinders, beware of grease, the power cord should be tied overhead.

10, fire prevention measures should be taken around and below the welding cutting point, and special personnel should be appointed for fire prevention monitoring.

Seven, water and electricity installation work matters needing attention

1, according to the requirements of the construction scheme;

2. When drilling, the sledgehammer shall not be loose, the shovel shall be free of curling and cracking, and the operators must wear protective glasses. When drilling holes in floor slab and brick wall, no one can be near under the slab or behind the wall;

3. When using the hand-held electric drill, the electric drill must be reliably connected to protect the zero line and repeatedly grounded, and the power cord must pass through the electric shock protector, which is sensitive and effective. Do not touch or press the power cord on the ladder;

4. When the pipe passes through the belt line, it is not allowed to make a phone call or blow on the nozzle to prevent the elastic hook with the belt line. Cooperate with each other when threading to prevent squeezing hands;

5, pipeline embedded position must be accurate, binding is firm;

6, the installation of lighting lines are not allowed to be directly on the slatted ceiling or sound insulation board or stacked materials. When it is necessary to pass, scaffolding should be laid on the wooden Fang;

7. The elbow of the manpower pipe bender should be selected in an appropriate place to prevent slipping and falling, and avoid the inside of the operation. When the pipe is heated, no one is allowed to stand or pass in front of the nozzle;

8. It is forbidden to connect or disconnect power with load on the line, and live working is prohibited;

9. Before the equipment is effectively grounded, power-on trial operation is not allowed.
