What are the potential dangers of temporary fences?

The totally enclosed temporary fence set up by outdoor high-voltage testers must adopt upper and lower layers of enclosure, and the height of the upper layer of enclosure should not exceed 1.2m, and only the testers are allowed to stay in the enclosure during the test. Temporary power supply for maintenance and test on the job site shall be connected to the job site before the fence is closed.

for the infrastructure construction operation of the switching yard in the substation for more than 1 days, the work area must strictly require the construction unit to install fixed fences around the work place, such as dry wood, rubber or other insulating materials, protective nets, etc., and its entrances and exits should be surrounded by adjacent roads.

when setting up temporary barriers and fences on site, it is necessary to fully consider whether there are live equipment around and above the operation interval, and the barriers and fences should be installed as far away from live equipment as possible. The installation of temporary fences and fences should be analyzed for safety risks, and clearly reflected in standardized work instructions and work tickets.

The correct installation of temporary fences and signboards on the construction site can effectively avoid the operation risks and erect a safe barrier for the construction workers.
