Question: An operator identifies an active hydraulic leak from the main boom extend cylinder during a pre-shift inspection. Alberta OHS Code Part 21 requires what specific action?

Answer options: ✅ The operator must immediately notify a supervisor and clearly tag the crane 'Out of Service' or 'Do Not Operate'.

• The operator should attempt to tighten the leaking fitting with tools available in the cab.
• The crane can be used for non-critical lifts until maintenance arrives later in the day.

Correct answer: The operator must immediately notify a supervisor and clearly tag the crane 'Out of Service' or 'Do Not Operate'.

Explanation: Alberta OHS Code Part 21 states that if a defect is found that may compromise safe operation, the crane must be removed from service immediately. This involves notifying a supervisor and clearly tagging the equipment to prevent its use until repaired.
