Emergency Response and First Aid Flashcards

What is the correct treatment for a second-degree thermal burn covering the forearm of an operator?

The EAP allows supervisors to conduct headcounts and ensure all personnel are safely evacuated.

A worker inhales chlorine gas and is coughing severely. After removing them from exposure, what is the next priority?
