A driver is inspecting a portable tank before loading a hazardous material. Which of the following conditions would immediately render the tank unsuitable for transport?
- AA missing data plate from the tank's frame.
- BA slightly discolored placard on one side of the tank.
- CSurface rust covering less than 5% of the tank's surface.
- DMinor paint scratches on the tank exterior.
Show answer & explanationAnswer & explanation
Correct answer: A. A missing data plate from the tank's frame.
The data plate contains critical information about the tank's design, construction, and certification, which are essential for verifying its suitability for hazardous materials. A missing data plate means the tank's compliance cannot be readily confirmed, making it unsuitable for transport.
Why the other options are wrong
- B. A discolored placard would need replacement for visibility but doesn't render the tank itself unsuitable for transport.
- C. Surface rust, if not deep or compromising structural integrity, is usually not an immediate disqualifier.
- D. Minor cosmetic damage like paint scratches typically does not affect structural integrity or regulatory compliance.
Portable Tank Pre-Trip Inspection
A thorough examination of a portable tank before loading hazardous materials to ensure it meets safety and regulatory requirements.
- Includes checking for structural integrity, leaks, and proper markings.
- Data plate presence and legibility are critical.
- Ensures the tank is fit for continued safe service.
Memory trick: Inspect the tank, find the flaw, follow the hazmat law!
