Question: You are performing a pre-shift inspection on a grader. You notice the FOPS (Falling Object Protective Structure) on the cab has a circular indentation of about 3 cm in diameter, and 5 mm deep, with no visible cracks. This damage is located on the flat top surface. What should be your next step?

Answer options:

• Document the indentation in the logbook and continue operation, as it appears minor. ✅ Report the indentation to your supervisor to determine if it affects the structure's integrity and tag out if unsure.
• Consult the machine's maintenance manual for specific damage limits on the FOPS.
• Smooth out the indentation with a grinder to prevent further stress concentration.

Correct answer: Report the indentation to your supervisor to determine if it affects the structure's integrity and tag out if unsure.

Explanation: Even minor damage to a FOPS can compromise its ability to protect the operator, especially from higher-energy impacts. As per provincial OHS regulations, the integrity of protective structures must be verified. If there is any doubt about the safety or structural integrity, equipment must be taken out of service until assessed by a competent person.
