Multiple Choice

There are ____ accepted methods of protection for a lineworker to keep from becoming energized.

Protecting a lineworker from becoming energized relies on three protective approaches: distance, guarding, and insulation. Distance means keeping a safe clearance from exposed energized parts so contact or an arc cannot reach the worker. Guarding uses physical barriers like covers or shields to prevent contact with energized parts. Insulation involves using non-conductive materials and insulating tools to prevent current from flowing if contact occurs. These three categories cover the main ways electricity could reach a worker and are the accepted methods when de-energizing isn’t possible, which is why the correct fill-in is three. Two would miss one of the essential categories, and four or five aren’t recognized as distinct standard methods.
