What must be checked immediately after turning on the gas in a new system?

Checking the piping system for leakage immediately after turning on the gas in a new system is crucial for several reasons. First and foremost, safety is the primary concern. Gas leaks can lead to serious hazards, including fire, explosions, and health risks due to inhalation of gas.

Once gas is turned on, it is essential to confirm that all joints and connections within the piping system are secure and free from leaks. This typically involves using a leak detection solution or a similar method to verify that no gas is escaping. Identifying a leak at this stage prevents potential disasters and creates a safer environment for both the technicians and occupants of the building.

Other considerations, such as appliance operation and gas pressure regulation, are important but come after ensuring the integrity of the gas piping system. If a leak is present, adjustments or operations of appliances or the pressure in the system could lead to further complications or dangers. Therefore, ensuring the piping system is leak-free must take precedence after gas activation.
