What is the first step a technician should take when identifying a gas leak?

When identifying a gas leak, the primary concern is safety. The first step a technician should take is to evacuate the area. This action ensures that individuals are kept at a safe distance from potential exposure to gas, which can be dangerous and poses a risk of explosion or fire. The technician's responsibility is to prioritize human safety above all else, and evacuating the area allows for an immediate response to ensure that no one is harmed while the leak is being assessed.

After ensuring that the area is safe and individuals are evacuated, the technician can then proceed to investigate the source of the gas leak through various methods, such as checking the gas meter, conducting a smell test, or inspecting gas appliances. However, all those steps must follow the fundamental principle of first ensuring that all personnel are safely away from the potential hazard.
