Why must only certain pipes and steam traps be guarded, specifically those within 7 feet of a walking surface?

The rationale for guarding only certain pipes and steam traps that are within 7 feet of a walking surface primarily relates to the prevention of incidental contact with hot surfaces. When pipes and steam traps are heated, they can pose a significant hazard to individuals in proximity, particularly if they are within a height that is easily accessible or encountered by workers.

By focusing on this specific height, organizations can effectively mitigate the risk of burns or other injuries that could occur if a person accidentally brushed against these hot elements while walking. Guarding these areas serves as a safety measure to alert and protect workers, enforcing a standard of safety in the workspace. This practice also underscores the importance of maintaining a safe environment, as unguarded hot surfaces can lead to serious injuries, compromising worker safety and well-being.
