Question $1$

$5$ pts

$-$ A $30-$year$-$old male electrical technician was helping a company service representative test the voltage$-$regulating unit on a new rolling mill. The input power line was $480$ V $.$

$-$ While the electrical technician went to get the equipment service manual, the service representative opened the panel cover of the voltage regulator's control cabinet in preparation to trace the low$-$voltage $(120$ V $)$ wiring in question $($the wiring was not colorcoded$).$

$-$ The service representative was not using PPE, the electrical technician was wearing the company issued $\backslash (8\backslash$mathrm$\{$cal$\}/\backslash$mathrm$\{$cm$\}^\{2\}\backslash )$ arc$-$resistant uniform, hard hat, working boots, ear inserts, and safety glasses.

$-$ The service representative climbed onto a nearby cabinet $4$ feet away from the voltage regulator's control cabinet in order to view the wires.

$-$ The technician returned and began working inside the control cabinet, near exposed, energized electrical conductors.

$-$ The technician tugged at the low$-$voltage wires while the service representative tried to identify them from above.

$-$ Suddenly, the representative heard the victim making a gurgling sound and looked down to see the victim shaking as though he were being shocked.

$-$ Cardiopulmonary resuscitation $($CPR$)$ was administered to the victim about $10$ minutes later. He was pronounced dead almost $2$ hours later as a result of his contact with an energized electrical conductor.

The representative was working inside the restricted boundary without protection.

No arc$-$flash risks were considered.

The job should have been done under an electrically safe work condition.

The technician was working inside the restricted boundary without shock protection.

The job should have been preceeded by an energized electrical work permit.
