You hear a vehicle engine running in your neighbor’s garage. When you open the door, you see your neighbor lying on the floor. What should you do first?

Explanation

Exhaust fumes from an engine running in a closed garage contain carbon monoxide and are poisonous to both the victim and the rescuer. So first open the doors wide, turn off the engine and, if possible, move the victim out into fresh air. Checking for injuries or positioning the victim comes only after the exposure to the gas has been stopped.
