FDNY CoF – Use of LPG or CNG in Engine Fuel Systems (G-22) Practice Test

The control valve on an LPG or CNG container is located on the top of each container. This positioning is significant because it allows for efficient access and operation, enabling easy regulation of the gas flow when needed. Having the control valve at the top facilitates a safe and effective means of controlling the release of gas, as it can quickly be shut off if necessary.

Positioning the valve at the top also considers the design of the containers, ensuring that the liquid gas, which tends to be denser and accumulates at the bottom due to gravity, can be safely managed. This is particularly important in safety protocols and operational efficiency, as managing gas flow effectively can minimize the risks of leaks or pressure issues.
