What action must be taken with eeds before performing an electrical continuity electrical repair or resistance check on an explosive facility?

Before performing an electrical continuity or resistance check in an explosive facility, all electrical equipment and circuits must be de-energized and properly isolated to prevent accidental activation. Additionally, the area should be assessed for any potential explosive atmospheres, and appropriate safety measures, such as grounding or bonding, should be implemented to mitigate risks. It is also crucial to follow facility-specific safety protocols and guidelines to ensure compliance with regulations.
