What action starts the flow of oxygen in a PBE?

Explanation:
The action starts the flow of oxygen when you actively activate the device by pulling the “Pull to Actuate” ring in the indicated direction. This ring acts as the safety trigger for the chemical oxygen generator inside the PBE; pulling it initiates the chemical reaction that produces oxygen and opens the flow to the hood. Other steps like opening the storage case, tearing a red pull strip, or adjusting the hood are preparatory or sealing actions and do not start oxygen production. Once the ring is pulled, oxygen begins to flow immediately and continues for the PBE’s rated duration.
