Question: A crane operator is required to operate within a reduced clearance from a power line because it's technically infeasible to maintain the standard exclusion zone. According to provincial OHS regulations and CSA Z150, which of the following is an absolute requirement for such an operation?

Answer options:

• The operator must be equipped with rubber insulating gloves. ✅ The power company must de-energize the line or provide an assurance of safe clearance in writing.
• A dedicated signal person must be positioned at the maximum swing radius.
• The ground must be completely dry before beginning the lift.

Correct answer: The power company must de-energize the line or provide an assurance of safe clearance in writing.

Explanation: If the standard exclusion zone from power lines cannot be maintained, provincial OHS regulations and CSA Z150 require that the power line either be de-energized and grounded, or that the power utility provides a written assurance of safe clearance (e.g., through physical barriers or insulation) before any work can proceed.
