What is required in the Gas Supply Line to a Boiler Room when the total input exceeds 2,000,000 BTUH?

When the total input of gas supply to a boiler room exceeds 2,000,000 BTUH, it is essential to have an identified accessible emergency manual shut-off valve in place. This valve plays a crucial role in ensuring safety by allowing quick manual intervention in the event of an emergency, such as a gas leak or fire. The accessibility of this valve is key, as it needs to be readily reachable by personnel in case of an emergency situation.

Having this shut-off valve established as a requirement helps mitigate risks associated with high-capacity gas systems. It ensures that operators can instantly stop the flow of gas when necessary, thereby minimizing potential hazards. This is especially important in boiler rooms, where the presence of significant amounts of gas can lead to dangerous situations if not managed correctly.

Other safety features, while important in their own right, do not specifically address the immediate need for manual gas shut-off in the context of high BTUH inputs. This makes the identified accessible emergency manual shut-off valve a fundamental necessity for safe operation in environments involving substantial gas consumption.
