What action should be taken if leakage is indicated during a test?

When leakage is indicated during a test, shutting off the gas supply is the necessary action to ensure safety. This step is critical because a gas leak poses immediate health risks, including fire hazards and potential exposure to harmful gases. By stopping the flow of gas, you minimize the chances of an explosion or fire occurring, providing a secure environment for further assessment and repairs.

Once the gas supply is shut off, appropriate measures can be taken to either locate the source of the leak and perform repairs, or conduct further testing to evaluate the extent of leakage. This action prioritizes safety and compliance with regulations governing propane systems, ensuring that all necessary precautions are taken before any subsequent actions can be pursued.
