Which of the following is NOT a requirement for a cargo tank vehicle in LP Gas operations?

In the context of LP Gas operations, cargo tank vehicles must adhere to specific safety and operational requirements to ensure safe handling and transportation of propane. Among these requirements, fireproof storage compartments are not mandated for cargo tank vehicles.

The primary focus for LP Gas vehicles is on safety features that prevent overfilling, provide proper weight markings for transport regulations, and ensure stability during loading and unloading processes, which chock blocks facilitate by preventing the vehicle from moving unexpectedly. Overfilling prevention devices are critical to avoiding spills and ensuring safe transfer procedures.

In contrast, while fire resistance is essential in the broader context of flammable gases, the specific requirement for cargo tanks does not include having fireproof storage compartments. This distinction is important for understanding how transportation safety regulations are structured in relation to the physical characteristics of the vehicles used in LP Gas operations.
