What are the safety precautions for winter construction?

Winter construction safety precautions are very important. The precautions are formulated to better solve practical problems, and the handling of every detail is very critical. Zhongda Consulting would like to introduce to you the safety precautions for winter construction.

1. On-site fire prevention

1. Strictly implement the fire application management system. It is prohibited to use electric welding and open flames during cross-cutting operations. If they must be used, a special safety plan must be prepared and signed and approved by relevant personnel.

2. When electrical welding operations must be performed, operators must hold certificates. The working surface must be well protected, and a dedicated person should be assigned to look after it. After work is over, recheck whether there are residual fire spots such as welding slag before leaving.

3. The construction site must be equipped with sufficient fire-fighting equipment and fire-fighting sand boxes, and everyone must be able to use them. At the same time, the construction site must be equipped with stable and reliable fire water sources and interfaces.

4. It is forbidden to light fires or smoke in the construction site. "No Fireworks" warning signs should be posted in prominent places. Strengthen on-site safety inspections, especially the storage and use of flammable and explosive dangerous goods.

5. Construction workers are strictly prohibited from living in unfinished units.

2. Education

1. Strengthen winter construction education for construction workers and always remind them of the precautions for winter construction.

2. Insist on conducting safety briefings 10 minutes before work every day and inspections 5 minutes after work to avoid safety hazards and keep records.

3. Make a special winter construction safety plan and submit it to the supervision unit and construction unit for approval.

4. Before the official start of construction, the construction unit must conduct technical briefings for all employees to familiarize workers with the project characteristics and precautions.

3. Electricity prevention

1. Strictly implement the temporary power consumption system of "three-level power distribution, two-level protection" and do a good job in grounding protection of electrical boxes. The circuit components in the distribution box must meet the relevant requirements for temporary power safety.

2. Power cables should not be run around on the ground, nor should they be rolled over. They must be erected with wooden poles, and the height from the ground should not be less than 2 meters.

3. It is forbidden for power cables to pass through standing water. It is strictly forbidden for cables to directly contact non-insulating materials such as metal and components to avoid personal injury caused by leakage.

4. Maintenance electricians must be certified to work and strengthen on-site management. If the surface of electric cables is damaged, they should be replaced in time.

IV. Temporary security

1. The fire protection system must be posted in a conspicuous position in each room, and the alarm telephone number and the contact number of the 24-hour personnel on duty in the temporary area must be indicated.

2. The temporary area must be equipped with sufficient and qualified fire-fighting equipment.

3. The use of prohibited heating methods (electric stoves, coal stoves, electric mattresses, etc.) is strictly prohibited in the temporary area to prevent circuit fires and gas poisoning.

5. Curtain wall construction in winter

A. Fall prevention

1. Personnel working at heights must be equipped with adequate and qualified safety protective equipment. At the same time, all safety protective equipment certificates must be submitted to the supervision unit for inspection and archived, and personnel working at heights must be strictly supervised and inspected to see whether they wear them in compliance with regulations.

2. The construction work surface must be covered with springboards, and the springboards must be locked with the scaffolding.

3. Construction must be stopped on windy days of Level 6 and above. External wall scaffolding should be made of plastic sheeting to prevent wind, and thermal insulation curtains should be hung to ensure normal construction for high-altitude workers.

4. Work in snow should be avoided. After snow, the snow on outdoor scaffolding and construction work surfaces should be cleared before work.

5. Equipment used in winter construction must be maintained in winter and antifreeze added to ensure the safety and smooth operation of the equipment.

6. Winter interior decoration

A. Waterproofing

1. It is recommended that decoration materials be stacked at a height of 20-30cm. Detach it from the ground.

2. When leaving the factory, check whether the faucet is closed tightly.

3. Workers who do not understand pipeline construction shall not be allowed to engage in water supply and drainage construction.

4. When laying solid wood floors or composite floors, attention should be paid to the waterproofing of adjacent areas.

5. Clean the drainage holes regularly to avoid blockage and flooding accidents.

B. Hazard prevention

1. Decoration materials should be placed properly, and sharp-edged objects should be appropriately pre-protected to prevent collision injuries.

2. Small metal accessories should be placed properly, especially nails. If there are nails on the used wooden boards, they should be bent and flattened in time.

3. Safety measures must be taken when working at heights, and sufficient equipment for high-altitude operations must be equipped, and the materials and tools stacked on the movable scaffolding should not be excessive or too high.

4. When stabilizing ceiling projects, installing lighting fixtures, etc., be sure to install expansion screws, and install more expansion screws just in case.

5. Personnel who have received formal training should operate various construction machinery and take necessary safety measures. Be especially careful about the safe use of machinery such as electric saws and high-voltage nail guns.

C. Chemical protection

1. Carefully place various chemical materials and take certain isolation measures.

2. Indoor ventilation should be maintained during paint debugging and paint construction to avoid poisoning, explosion and other accidents caused by large amounts of toxic substances in the air.

3. When using chemical materials, wear protective measures such as rubber gloves.

4. For unknown objects or materials, remember not to touch them randomly.

5. Do not prepare chemical raw materials without expert guidance.

6. Safety protection must be strengthened for strong acids, strong alkali, and highly volatile materials.
