Key points of resumption safety inspection: 1
.
Define the scope of safety responsibilities of management personnel at all levels, and the safety responsibilities of enterprise principals, project managers, heads of relevant functional departments, team leaders and front-line production workers, so as to ensure that special personnel are full-time
.
After the typhoon, many construction sites in a hurry to return to work
.
2
.
Check the potential safety hazards such as falling from the edge of the building, entrance, climbing operation, falling from the operation platform, lax protection of the construction basket and construction elevator, and prevent falling accidents from height

.
3
.
Focus on the safe operation of maintenance personnel to prevent accidents
.
For the common unsafe behaviors in violation of operating procedures in construction, carefully analyze the causes, put forward safety precautions, and eliminate the safety production accidents caused by unsafe behaviors of employees
.
Here’s a reminder: please conduct safety inspection before returning to work, so as to eliminate the occurrence of secondary disasters and safety accidents
.
Strictly implement the on duty system for safety managers at all levels, require managers to go deep into the front line and command ahead, and ensure that all safety production rules and regulations are not verbal, but effectively implemented in each production post and in the whole production process of employees
.
The second pass: personnel training
.
After the rain, the pit, groove, ditch slope and fixed wall support structure shall be inspected in time, and special personnel shall be assigned to measure the deep foundation pit and observe the slope
.
If there are dangerous signs such as cracks, looseness, broken support structure and walking on the slope, measures shall be taken immediately
.
Check the effectiveness of tower crane bolts, attached walls and safety limit devices, timely drain the accumulated water in the foundation, and put into use after passing the test run
. 
Before returning to work, carry out safety training for all employees, learn national laws and regulations on safety production, and learn various safety operation specifications, procedures and safety management systems
.
Strengthen the monitoring around the foundation pit, especially the projects adjacent to inland rivers or rivers and lakes shall be equipped with sufficient submersible pumps and other drainage facilities to ensure timely drainage and prevent foundation pit collapse
.
The damaged and deformed parts shall be reinforced or replaced in time, and can be put into use only after passing the re acceptance
.
Check the operation links and dangerous parts of the construction site, such as earthwork excavation works, underground excavation works and other high-risk operations that are prone to major accidents such as mass deaths and injuries
.
Pay attention to the safety of temporary power supply during pumping and drainage, configure switch box and assign special personnel to be on duty
.
It is necessary to improve the safety production responsibility awareness of managers, establish the concept that irresponsible safety managers are dereliction of duty and illegal command is a crime, drive the majority of employees to consciously pay attention to safety, always pay attention to safety, seriously abide by various safety production rules and regulations, consciously eliminate illegal operations and eliminate various unsafe behaviors through the conscious actions of managers, Resist illegal command and reduce the occurrence of various safety production accidents
.
4
.
Employees shall be educated to strictly abide by various rules and regulations of safety production, operation procedures of safety production, labor discipline, resolutely refuse command against rules, stop unsafe behaviors of others in time, and reduce safety production accidents caused by human misoperation
.
5
.
6
.
Timely drain the accumulated water on site
.
It is strictly prohibited to undertake the installation and disassembly of construction hoisting machinery without safety production license, qualification certificate or beyond the scope of qualification business; Personnel without special equipment operation certificates are not allowed to work; The construction hoisting machinery and climbing scaffold with serious potential safety hazards shall be stopped, and the responsible unit shall rectify them to eliminate the potential safety hazards in time and prevent the lifting injury caused by crane overturning and other accidents
. 
Temporary facilities such as dormitories and offices shall be comprehensively inspected and re accepted
.
In case of inclination, sinking, loosening of wall connecting parts, node connection displacement, falling off of safety net, rope opening and other phenomena, they shall be handled in time
.
The third level: hidden danger investigation
.
“Four safety passes” for resumption of work: the first pass: responsibility implementation, further implement the main responsibility of safety production, and improve the safety production responsibility system
. 
Before returning to work on the construction site, check the tower crane, construction elevator, well frame and other large equipment, focusing on whether the torque limiter fails, whether the overload operation is carried out, whether the crane wire rope is firm, whether the anti decoupling device fails, whether the disassembly scheme is formulated, and whether the inspection and acceptance procedures are performed, Whether the on-site disassembly and use meet the safety requirements
.
