Surrounding trenches with a high fence is a crucial safety measure at a job site because it provides a physical barrier that helps prevent unauthorized access and reduces the risk of accidental falls into the trench. This type of fencing can deter pedestrians and workers who might unknowingly approach the trench, thus protecting them from potential injuries.

While marking trenches with cones is a good practice for visibility, it may not provide the same level of safety as a high fence, which offers a more definitive separation between workers and the hazards of an open trench. Covering trenches with plastic sheeting does not address the risk of falls and may not be effective in preventing accidents due to visibility issues. Leaving trenches open for safety checks poses a significant risk, as it exposes workers to hazardous conditions. Thus, surrounding trenches with a high fence is recognized as a best practice in trench safety management.
