Associate Safety Professional Practice Exam

The maximum burst pressure required for LPG hoses is established to ensure safety and reliability during handling and transportation of liquefied petroleum gas. The correct answer of 1250 psig (pounds per square inch gauge) meets industry standards designed to handle the pressures associated with LPG usage.

LPG hoses are subject to high pressures, especially during transfer processes, and must be designed to withstand significant stress without failure. The established burst pressure ensures that under normal operating conditions and even under extreme circumstances, the hose will not rupture, thereby minimizing the risk of leaks, which could lead to fire hazards or other dangerous scenarios.

This safety measure is critical in preventing catastrophic failures in environments where LPG is used, contributing to overall workplace safety. The other options, while they may seem like plausible burst pressures, do not align with the current industry standards set for LPG hoses, which specifically mandate a minimum burst pressure of 1250 psig to maintain safety factors and reliability.
