What does OSHA require regarding temporary protective grounds?

OSHA requires temporary protective grounds to prevent employees from being exposed to hazardous potential differences. This is crucial because, during maintenance or repair work on electrical systems, it is essential to ensure worker safety by minimizing the risk of electric shock or arc flash.

Using temporary protective grounds effectively creates a path for fault currents to safely dissipate, thereby neutralizing hazardous voltages that might otherwise pose a risk to workers. This approach aligns with OSHA's overarching goal of ensuring a safe working environment and mitigating electrical hazards in potentially dangerous situations.

In this context, the necessity for grounding to effectively interrupt hazardous conditions underlies the critical need for such measures whenever temporary conditions arise. While other options touch on aspects of grounding practices, they do not specifically address the primary safety goal that OSHA emphasizes regarding potential electrical hazards.
