When must a flexible connector on a cargo tank vehicle be inspected?

A flexible connector on a cargo tank vehicle must be inspected before the first delivery each day to ensure safe operation and compliance with safety regulations. This inspection is crucial because flexible connectors are critical components that can be subject to wear and tear, which may lead to leaks or failures. By conducting this inspection daily before the first delivery, potential issues can be identified and addressed, thereby reducing the risk of accidents, leaks, and environmental hazards during transportation of liquefied petroleum gas.

The practice of daily inspections before the first delivery aligns with the principle of proactive safety management, which is emphasized in NFPA guidelines. Regular checks help maintain the integrity of the cargo system and ensure that the vehicle is in optimal condition for safe operation throughout the day.
