What is the recommended action for a healthcare worker if someone is on fire?

Wrapping the person in a blanket to extinguish the flames is the appropriate action in this scenario. A blanket can smother the fire by cutting off the oxygen supply, which is essential for combustion to continue. It helps to cool the flames and protect the person from further burns. This technique is commonly taught in emergency response training and can be vital in effectively controlling the situation until professional help arrives.

Using water might seem intuitive, but it can sometimes cause flames to spread or lead to serious injuries if the fire is fueled by flammable liquids. Running away from the scene would not provide any assistance to the person in danger and would not help to mitigate the fire. While calling for help is important, it must be accompanied by immediate action to put out the fire, rather than just screaming. This makes wrapping the individual in a blanket the most effective and recommended response.
