A driver is inspecting the air storage tanks and notices that one of the tanks has a small dent, but no visible air leak. According to regulations, what is the most appropriate action for the driver to take?
- AReport the damage and have the tank inspected by a qualified mechanic.
- BMonitor the dent for any changes during the trip.
- CImmediately drain the tank and continue the trip.
- DApply a temporary patch to the dent and proceed with caution.
Show answer & explanationAnswer & explanation
Correct answer: A. Report the damage and have the tank inspected by a qualified mechanic.
Air tanks are pressure vessels and are designed to very strict specifications. Any damage, even a small dent, can compromise the structural integrity of the tank under pressure and lead to catastrophic failure. Federal regulations (e.g., FMCSR 393.45) require that air tanks be free of damage that affects their safe operation. A qualified mechanic must inspect it.
Why the other options are wrong
- B. Monitoring is insufficient for a critical pressure vessel component.
- C. Draining the tank doesn't resolve the structural compromise; the tank still needs inspection.
- D. Temporary patches are not acceptable for high-pressure air tanks due to safety risks.
Air Storage Tank Integrity
Air storage tanks are critical pressure vessels whose structural integrity must be maintained. Any physical damage, such as dents or corrosion, requires professional inspection and repair/replacement.
- High-pressure vessels, critical safety component.
- Dents can compromise structural integrity.
- Requires inspection by qualified personnel.
