What is the maximum pressure allowed in a cylinder of propane?

The maximum pressure allowed in a cylinder of propane is based on safety standards and the physical properties of propane as a gas. Propane is stored in pressurized cylinders as a liquid, and when the cylinder is filled, it maintains a specific pressure that should not be exceeded to ensure safe usage and prevent hazards like ruptures or explosions.

The correct answer indicates that 375 PSIG is the upper limit for the pressure in a standard propane cylinder. This figure is widely accepted within the industry, ensuring that cylinders can safely contain and deliver propane for various applications. Understanding these pressure limits is crucial for technicians to safely handle propane, maintaining equipment and storage systems in accordance with regulatory guidelines.

Lower maximum pressure options would not be consistent with the proper operational capacities of propane cylinders, as these would potentially lead to inefficiencies in usage or reduced performance when delivering propane to appliances. Therefore, 375 PSIG represents a balance of safety and operational effectiveness in propane storage and handling.
