What is one critical inspection point before turning on gas service?

Ensuring that all connections are tight and secure is a critical inspection point before turning on gas service because it directly impacts safety and functionality. Loose or improper connections can lead to gas leaks, which pose significant hazards including fire risks and health dangers from inhalation of gas. Maintaining a secure connection ensures that the gas is delivered efficiently and safely to the appliance, thus preventing any potential accidents or malfunctions.

While checking for a strong odor of gas is important, it is typically a sign of a leak rather than a preventive measure. Waiting for approval from local authorities is a procedural step that may not be necessary in all cases, depending on local regulations and the specific project. Visual confirmation of appliance condition is also relevant, but ensuring the integrity of connections takes precedence as it is fundamental to safely initiating gas flow to any appliances.
