Anti slip measures shall be taken during construction.
Keep your body warm and pay attention to prevent frostbite.
Those used in the open air must be equipped with rain, snow and moisture proof facilities.
Skid strips or straw bags shall be nailed on the springboards with slopes, and the scaffold shall be checked for looseness and subsidence at any time.
Scaffolds and scaffold boards with ice and snow shall be cleaned before construction.
6、 To prevent traffic accidents, the weather is cold and freezing in winter, the road surface is wet and slippery, and there are many foggy days, so the site is prone to traffic accidents.
The personnel engaged in toxic operations and operations with asphyxiation risk must be educated on the safety knowledge of poison prevention and first aid, and the operation management must be strengthened.
4、 The explosion-proof air is dry in winter, which is easy to form potential explosion hazards such as static electricity accumulation.
The construction site shall be drained of accumulated water, and drainage measures shall be taken to prevent icing and other phenomena caused by on-site construction water.
When construction is carried out at the freezing place, it is necessary to lay anti-skid grass felt or wood plate with anti-skid strips, and wear safety rope to fix it on the firm fulcrum.
The post personnel shall operate in strict accordance with the equipment process parameters to prevent human error and ensure safe operation.
Power switches, control boxes and other facilities shall be arranged in a unified way, and locked for protection to prevent disorderly pulling of wires.
If concrete pouring is involved, pay attention to adding antifreeze.
Special personnel shall be assigned for management to prevent electric leakage and electric shock.
It is strictly prohibited to hang the safety belt on the template when installing the template.
Precautions and requirements for construction safety in rainy and snowy days 1.
All mechanical sheds on site shall be erected tightly to prevent rain leakage; Waterproof and flood prevention measures shall be taken for electromechanical equipment; After rain and snow, the power supply lines shall be checked to ensure the safety of electricity use.
3、 It is windy and dry in winter to prevent fire.
Regularly carry out special inspection on tower cranes, elevators and other equipment, focusing on equipment maintenance, wire ropes, rotating parts, etc.
It is necessary to strengthen the publicity and education of traffic safety for employees and educate them to pay attention to daily traffic safety.
In case of rainy and snowy weather, timely clean the snow and frozen ice.
4.
Strengthen the maintenance and inspection of fire extinguishing facilities in the above parts to ensure that they are in use at any time.
Wires of frequently moved machines and tools shall not be dragged on the ground or intruded into the water.
5.
Due to cold weather and slippery snow, operators shall not take risks or work against rules, and shall wear safety helmets as required.
Strictly implement the three-level patrol inspection system, strengthen the inspection of fire emergency equipment, pipe network facilities and electrical circuits, timely rectify problems found, put an end to “leakage”, and eliminate hidden dangers in the bud.
They shall be well insulated overhead.
7、 Since there are many cases of self heating in winter to prevent poisoning and suffocation, the staff should be educated to pay attention to the protective measures of self heating to prevent gas poisoning.
3.
We should take the initiative to prevent snow disasters, wind disasters and other abnormal weather.
10.
For temporary electricity use, the approval system shall be strictly enforced and management shall be strengthened.
2.
9.
Special personnel shall be assigned for management to prevent electric leakage and electric shock.
Climbing operators (structural construction support erection, foundation pit excavation steel support installation, etc.) must wear anti-skid shoes, protective gloves and other anti-skid and antifreeze facilities; The personnel working at heights must correctly fasten the safety belt as required, and must hang the safety belt hook on a safe and secure object.
After pouring, cover the membrane first and then cover the straw curtain for insulation.

Anti freezing 1.
8、 Prevention of abnormal weather In recent years, abnormal and disastrous weather occurs frequently.
The snow on the construction site shall not be stacked near the electromechanical equipment and component stacking site after cleaning.
Therefore, it is necessary to strengthen the inspection of the fire and explosion prevention areas, focusing on the inspection and management of the storage areas of inflammable and explosive materials; For the processing workshop with high dust concentration, the scattered and accumulated dust shall be cleaned in time.
