According to CSA Z150-16 for mobile cranes, what is required if a crane is to be operated within the minimum approach distance of an energized power line?

Question: According to CSA Z150-16 for mobile cranes, what is required if a crane is to be operated within the minimum approach distance of an energized power line?

Answer options:

• The operator must be specially certified for high-voltage work. ✅ The power line must be de-energized, insulated, or the crane must be effectively grounded.
• A designated signal person is sufficient to ensure safety.
• The crane must be equipped with specific voltage-sensing devices only.

Correct answer: The power line must be de-energized, insulated, or the crane must be effectively grounded.

Explanation: CSA Z150-16 states that if operating within the minimum approach distance to an energized power line, the line must be de-energized and grounded, or insulated, or other equally effective protective measures must be implemented. Mere voltage-sensing devices or signal persons are not sufficient on their own.
