What is the recommended method for guarding holes while working?

Using a truck to protect the work area is a practical method for guarding holes while working. This approach provides a physical barrier that can help prevent accidents by clearly delineating the work area and protecting workers from falling into a hole that is not immediately visible. Trucks can be positioned around the hole to divert foot traffic and ensure that others are aware of the potential hazard. Furthermore, this method can also serve as a reminder for the safety protocols that should be followed in the vicinity of the hole.

In contrast, simply warning about the hole with a sign does not provide a physical barrier or sufficient prevention against accidents. Not working on high wind days does not address the specific hazard of the hole itself. Filling the hole with dirt may temporarily eliminate the hazard but does not allow for ongoing work and inspections, which could present a new issue if the hole was intended for a specific purpose such as utility work. Therefore, using a truck as a protective measure is a robust and proactive strategy to ensure safety on the job site.
