What is the maximum internal pressure of a low pressure rail car?

The maximum internal pressure of a low pressure rail car is typically 25 psi. This designation is important within the context of hazardous materials transportation, as it indicates the structural integrity and design specifications for low pressure rail cars, which are utilized for transporting various liquids and gases, including some hazardous materials. The 25 psi limit ensures that the car is equipped to handle the pressures associated with the substances it carries while maintaining safety protocols during transit.

Understanding the significance of this pressure threshold also aids firefighters and first responders in determining the appropriate response protocols when dealing with incidents involving low pressure rail cars. The characteristics of these rail cars can significantly influence the strategies used for stabilization, containment, and remediation efforts in the event of a spill or leak.
