During a carbon monoxide investigation, what initial action should personnel take regarding the occupants?

The appropriate initial action during a carbon monoxide investigation is to assist the occupants in evacuating the area. Carbon monoxide is a colorless, odorless gas that can be deadly, and the primary concern in such situations is the immediate safety of all individuals present. It is important to remove them from the environment where they could be exposed to the gas.

Instructing occupants to evacuate helps to quickly minimize their risk of exposure and potential harm. Once the area is safe and the individuals have been removed, further actions such as medical assistance or first aid can be appropriately assessed and administered. Helping to ensure that occupants are safe and out of danger aligns with standard procedures in hazardous material incidents, prioritizing health and safety above all else.
