According to the above hazard source analysis, the following safety accidents are easy to occur in winter construction: for the above prone accidents, vigilance should be raised for prevention during construction.
In addition, the dry climate in northern winter is easy to cause fire.
Fire protection management of the central material warehouse the person in charge of the material warehouse shall be fully responsible for the safety and fire prevention of the material warehouse.
What is winter construction? According to code for winter construction of building engineering (JGJ / t104-2011) stipulates that when the outdoor daily average temperature is stable below 5 ℃ for 5 consecutive days, winter construction will enter; when the outdoor daily average temperature is higher than 5 ℃ for 5 consecutive days, winter construction will be cancelled.
The electric tools shall be qualified by professional electricians.
6.
Strengthen the management of power consumption on the construction site to prevent electrical fire.
Therefore, in winter construction, measures to prevent falling from height must be in place, and the safety awareness of operators in the process of operation needs to be in place.
It is dry in winter.
In addition, bad weather also has a certain impact on power lines, so the safety of electricity must be borne in mind in winter construction.
Inflammables entering the material warehouse shall be stored by category, and warning signs and fire extinguishers shall be hung.
Winter is a high incidence period of mechanical injury and vehicle injury.
When using electric tools, check whether the power supply has leakage protector.
It is strictly prohibited to pull and connect lines without permission.
Special grounding line shall be set for electric welding operation.
2.
1.
Smoking in the dormitory area, using high-power electrical appliances and stacking flammable materials in the material warehouse are easy to cause fire due to careless management.
The hot work permit can only be used at the specified place and time.
3.
It is strictly prohibited to use bare wires.
8.
During open fire operation, there must be a hot work permit.
3.
Measure whether the insulation resistance meets the requirements.
The temperature in winter in the north is low, and the construction face and roads are easy to freeze and slip.
Under the influence of severe weather such as heavy fog and snow, the driver’s line of sight is hindered when the vehicle travels, so it is prone to traffic accidents.
1.
General knowledge of fire safety in winter construction （1） Fire safety in winter due to the low temperature in northern winter, many potential fire accidents are likely to occur during personnel heating and constant temperature in production.
3.
Cables with more than three broken skins shall not be put into use.
For power tools that are not used for a long time and are affected by moisture, professional electricians shall be allowed before use.
Wires, lamp sockets and electrical equipment The installation of spare parts must be carried out by a professional electrician.
（2） Electric shock accident in winter construction is one of the most common accidents in construction.
10.
Strengthen the power management of construction in winter.
5.
2.
Such accidents are often caused by people’s negligence and illegal operation.
More electricity is used in winter than usual.
During aerial welding, inflammables and explosives are strictly prohibited to be stacked below.
General safety knowledge of high-altitude operation in winter construction high-altitude operation is one of the major hazard sources in construction under normal circumstances.
Before leaving the site after the operation, the fire user shall confirm that the fire has been extinguished and there are no hidden dangers around.
When using electric tools, the original plug of electric tools shall not be removed or replaced, and it is strictly prohibited to directly insert the cable wire into the power socket without using the plug.
2.
They shall be stored 10m away from the open fire.
The storage distance between acetylene cylinders and oxygen cylinders shall not be less than 5m and shall not be placed upside down.
If the shell and handle of the electric tools are found to be broken, the power cord is damaged, and the plug is damaged, they shall not be used.
9.
The storage and use of inflammables and explosives shall be managed by a specially assigned person, and fire prevention measures shall be taken.
Implement anti-skid safety measures and timely clean the snow on the working face and construction road to prevent accidents caused by careless falls during operation or walking.
Special personnel must be assigned to watch the fire during open fire operation.
5.
In addition, the road is wet and slippery.
The fire-fighting facilities in the station shall be inspected on time, and the fire extinguisher shall be replaced immediately in case of failure.
1.
Open fire is not allowed to keep warm in the dormitory, and smoking in bed is strictly prohibited.
It is forbidden to hang wires and hang clothes on the electricity and lines.
4.
In addition, the wet and slippery construction surface in winter is more likely to induce high-altitude falling accidents.
After the use of electrical equipment, confirm that the power supply has been cut off.
