If there is a gas odor detected in a commercial building, what is the first step that should be taken?

When there is a detectable gas odor in a commercial building, calling 911 is the most appropriate first step because it immediately alerts emergency responders who are trained to handle gas leaks and related emergencies. Fire departments and other emergency services have the expertise to assess the situation safely and take necessary actions to protect occupants.

The priority is to ensure the safety of everyone in the building, and while evacuating occupants is also critical, it should be done under the guidance of emergency personnel to mitigate the risk of ignition from improper evacuation procedures. Utility services may need to be contacted afterward, but the safety protocols dictated by emergency services should come first. Conducting an inspection of the facility may occur after emergency responders have assessed and controlled the situation, but the initial focus must be on immediate safety measures.
