Question: 1 / 165

Which device is essential for preventing gas flow during a pull-away incident?

Manual switch

Gas leak detector

Break-away protection

A break-away protection device is designed to prevent gas flow during a pull-away incident by providing a method to disconnect the fuel line safely. This device ensures that if the connection between the fuel tank and the vehicle is compromised due to excessive force or movement, it will separate in a way that minimizes the risk of gas leakage. This is crucial for safety, as it reduces the chance of a gas leak that could lead to a fire or explosion if an incident occurs while refueling or during transit.

Other devices, such as a manual switch or a gas leak detector, have different functions. A manual switch would allow an operator to stop gas flow, but it is not automatically triggered in an emergency situation. A gas leak detector helps identify leaks but does not prevent them from happening during an incident. A pressure relief valve is vital for maintaining safe pressure within the storage system, but it does not specifically address the risk associated with pull-away incidents. Thus, break-away protection is the essential device for managing gas flow effectively during such situations.
