What marking is required for hoses designed for LP Gas transport?

Hoses designed for LP Gas transport are required to have markings indicating the working pressure at intervals. This is critical for safety, as it informs the user of the maximum pressure the hose can withstand during operation. Knowing the working pressure helps prevent accidents caused by over-pressurization, which can lead to hose failure, leaks, or even explosions.

The markings must be visible and clear, ensuring they can be easily read by personnel handling the equipment. This regulation is a key part of safety protocols in the handling and transportation of propane, contributing to the overall integrity of the system. Other types of markings, such as the type of gas or inspection dates, may be helpful but do not provide the same level of essential, operational knowledge as the working pressure markings do.
