To what height should wall openings be protected during demolition activities?

When addressing the protection of wall openings during demolition activities, the standard practice established by OSHA requires that these openings be protected at a height of at least 48 inches. This specification is designed to reduce the risk of falls and injuries to workers who may be operating near or around the openings created in walls.

The height of 48 inches has been identified as a critical threshold that serves to effectively guard against individuals accidentally falling through openings and helps ensure their safety during the hazardous task of demolition. Additionally, this height aligns with general safety practices that consider the average reach and height of workers, making it appropriate for providing protective measures that are both effective and accessible.

In contrast, other height options do not align with established safety regulations or practical safety standards for protection levels during demolition activities.
