What must be done to drill holes that are large enough to constitute a hazard?

When drilling holes that could pose a hazard, it is essential to ensure that they are covered or guarded to prevent accidents and injuries. This measure is a crucial safety protocol in mining and construction environments, where open holes can lead to falls, equipment damage, or unintended access to dangerous areas.

Covering or guarding the holes serves multiple purposes. It physically prevents individuals from accidentally stepping into or falling through the holes, which could have severe consequences. Additionally, guarding these areas can also provide clear visibility, helping workers remain aware of their environment and the potential hazards present. Proper guarding or covering techniques could include utilizing physical barriers or protective materials that create a safe environment for personnel working in the vicinity.

While marking the holes with flags or filling them with rubble might seem like safety considerations, they do not effectively eliminate the danger associated with open holes. Marking might help alert workers to the presence of a hazard but does not provide physical protection. Similarly, filling holes with rubble might not guarantee they remain stable or safe for work conditions. Therefore, covering or guarding is the most effective means to mitigate the risk associated with large drilled holes.
