Question: You are inspecting a compact excavator with an enclosed cab. You notice that the Plexiglas window in the front of the cab, which is part of the FOPS structure's integrity, has a significant crack spanning 15 cm. What is the appropriate response?

Answer options:

• Continue operation, as it's just a window and not a critical structure.
• Patch the crack with clear tape and monitor it. ✅ Tag out the machine and report the damage, as the FOPS's integrity is compromised.
• Operate the machine with extra caution.

Correct answer: Tag out the machine and report the damage, as the FOPS's integrity is compromised.

Explanation: Even though it's a window, if it's integrated into the FOPS structure and significantly cracked, its ability to protect the operator from falling objects is compromised. The machine must be tagged out and repaired by qualified personnel. (CSA B352)
