In smoky cabin conditions, which equipment should crew don for breathing protection?

In smoky cabin conditions the priority is a source of breathable air that isn’t contaminated by the smoke. Protective Breathing Equipment provides that: a hooded, self-contained air supply that delivers clean air to the wearer and creates a slight positive pressure to help keep smoke out. This lets crew move through the smoke, locate the source of the fire, and assist passengers while evacuating. The other items don’t address breathing protection—a life vest is for flotation, goggles protect eyes, and earplugs protect hearing—so they don’t provide the necessary air supply.
