What is the first step before setting personal protective grounds on a 15kV metal-clad system?

The first step before setting personal protective grounds on a 15kV metal-clad system is to complete the lockout/tagout procedure. This procedure ensures that all sources of energy are effectively isolated and cannot be inadvertently re-energized while work is being performed on the system. By properly executing the lockout/tagout procedure, personnel can effectively prevent electrical accidents that could lead to injuries or fatalities. This fundamental safety practice is crucial, as it establishes a secure working environment before any additional safety measures, such as personal protective grounding, are implemented.

The completion of the lockout/tagout procedure is a prerequisite to ensure that the system is safe for maintenance or work activities. Once this is done, other safety measures, such as measuring ground resistance or conducting insulation resistance testing, can be responsibly undertaken to further ensure safety.
