Question: When inspecting a large articulated dump truck (ADT) during a pre-operational walkaround in Northern Alberta, you discover a significant crack in a main structural weld of the chassis. What is your immediate course of action according to provincial OHS regulations?

Answer options:

• Record the defect in the logbook and continue operations, scheduling repair for the next maintenance window.
• Attempt a temporary field repair with welding equipment if available on site to complete the shift. ✅ Immediately red tag the equipment, remove it from service, and report the defect to your supervisor.
• Reduce the load capacity for the workday and operate carefully until repairs can be arranged.

Correct answer: Immediately red tag the equipment, remove it from service, and report the defect to your supervisor.

Explanation: OHS regulations in Alberta (and other provinces) mandate that any defect affecting the safe operation or structural integrity of heavy equipment must result in the equipment being immediately red-tagged, removed from service, and reported. This prevents hazardous operation. (AB OHS Code, Part 2, Section 20)
