At 3 PPM, what action should be taken according to precautions for HFP?

Explanation:
When a hazardous substance like HFP is present at a low concentration, the first priority is to limit inhalation by using appropriate respiratory protection. Donning a mask immediately reduces the amount of toxic fumes you breathe in, which is the most effective quick action at this level. Evacuation or seeking shelter would be more appropriate if the concentration were higher or if the release was ongoing and could escalate, while calling for decon is a step taken after exposure to remove contaminants from the skin and clothing. So at this level, putting on the mask is the correct protective step.
