What is a key requirement for pressure relief valves in a CNG system?

They must be manually operated.
They must not discharge gas towards occupied areas.
They must be positioned inside buildings.
They can only discharge gas during maintenance.

The correct answer is: They must not discharge gas towards occupied areas.

The requirement that pressure relief valves in a CNG system must not discharge gas towards occupied areas is crucial for safety. Pressure relief valves are designed to release excess pressure to prevent the risk of an explosion or system failure. If these valves were to discharge gas towards populated areas, it could pose significant safety hazards, including the potential for fire or exposure to high-pressure natural gas. By directing discharges away from populated areas, the design ensures that any released gas dissipates harmlessly into the atmosphere, reducing the risk of injury to people and damage to property. This requirement emphasizes the importance of protective measures in maintaining safety standards within natural gas systems. In contrast, the other options misunderstand the operational and safety protocols associated with pressure relief valves and their necessary positioning and function in a CNG system.
