Where must a shutoff be installed if the gas system serves more than one building?

Placing a shutoff valve outside at each building is essential for safety and accessibility. In scenarios where a gas system serves multiple buildings, having external shutoff valves allows for quick access in case of emergencies, such as a gas leak or fire. It ensures that each building can be independently shut off without needing to enter the premises, which may not be feasible or safe during an emergency situation.

Additionally, this setup conforms with safety standards and regulations that prioritize the protection of life and property. By having an easily accessible shutoff at each building, responders can act swiftly to mitigate any hazards, providing added assurance for occupants and emergency personnel alike.

While a shutoff at the meter location or at the main gas line entry could serve some functions, it may not provide the same level of accessibility or effectiveness for emergencies involving individual buildings. Having shutoff capabilities outside each building simplifies the process, ensuring safety measures are in place.
