A crane operator is required to perform a lift in a remote area where standard rescue services have a response time exceeding one hour. The lift itself involves personnel being hoisted in a man-basket. What additional safety measure, beyond the standard requirements for man-basket operations, is critically important here according to CSA Z150?

Question: A crane operator is required to perform a lift in a remote area where standard rescue services have a response time exceeding one hour. The lift itself involves personnel being hoisted in a man-basket. What additional safety measure, beyond the standard requirements for man-basket operations, is critically important here according to CSA Z150?

Answer options:

• Ensuring the man-basket is painted with high-visibility colours. ✅ Having a secondary, independent means of rescue immediately available.
• Only operating the crane at 50% of its rated capacity.
• Completing the lift within 30 minutes to reduce exposure.

Correct answer: Having a secondary, independent means of rescue immediately available.

Explanation: When hoisting personnel and rescue services are delayed, CSA Z150 (and OHS regulations) often mandate a secondary, independent means of rescue and retrieval be immediately available on site. This ensures personnel can be safely rescued from height in the event of a crane malfunction or emergency. High-visibility paint or reduced capacity alone would not address the rescue contingency.
