On a vibratory roller, during your pre-operation inspection, you notice a segment of hydraulic hose showing severe chafing where it rubs against a metal frame. The abrasion has worn through the outer cover but has not yet reached the reinforcement layers. What is the safest course of action?

Question: On a vibratory roller, during your pre-operation inspection, you notice a segment of hydraulic hose showing severe chafing where it rubs against a metal frame. The abrasion has worn through the outer cover but has not yet reached the reinforcement layers. What is the safest course of action?

Answer options:

• Wrap the chafed area with electrical tape and monitor it closely for the shift.
• Install a protective sleeve over the chafed area and continue operation. ✅ Tag the machine out for immediate hose replacement.
• Apply a strong adhesive or epoxy to reinforce the worn section.

Correct answer: Tag the machine out for immediate hose replacement.

Explanation: Hose chafing can quickly lead to complete hose failure under pressure, creating a high-pressure fluid injection hazard (which can cause severe injury) and equipment downtime. CCOHS and IUOE emphasize that any compromised hydraulic hose should be replaced immediately, not temporarily patched.
