You have finished digging a hole for a hydraulic (hydro) system, and the jack is not on site. What must the hole have on it before you leave?

A sign stating "Hole under construction"
A temporary barrier
A welded cover
An orange traffic cone

The correct answer is: A welded cover

The correct answer emphasizes the importance of safety and ensuring that the hole remains secured and safe until the jack is installed. A welded cover provides a strong, durable layer that prevents anyone from accidentally falling into the hole and protects the construction site from debris or other hazards. This is crucial in construction environments, where open holes can pose serious risks. While other options like a sign or traffic cone may enhance visibility and indicate that construction work is ongoing, they do not offer the same level of physical protection as a welded cover. A temporary barrier could also offer some protection, but it may not be as robust or secure as a welded cover, which acts as a definitive safeguard against accidents. Therefore, the welded cover is the most effective choice to ensure safety at an unfinished hydraulic system site.
