What is the proper method to inflate an adult life jacket?

The method for inflating an adult life jacket correctly involves two primary actions: pulling the red toggle and blowing into the tube. Pulling the red toggle initiates automatic inflation by releasing the gas stored within the jacket, which is designed for quick inflation in an emergency situation. Additionally, blowing into the tube provides an extra means to ensure that the jacket is adequately inflated to provide buoyancy.

This dual-method approach ensures that the life jacket is inflated promptly and allows for manual adjustment if needed. The ability to blow into the tube is especially useful in situations where the automatic inflation mechanism might fail or if immediate inflation is not possible.

In contrast, relying solely on pulling the yellow tab may not suffice for adults, as the tab typically activates a vest for child-sized jackets. Filling an adult life jacket with cabin air is neither standard nor safe, as it would not ensure proper buoyancy. Therefore, the method of using the red toggle combined with blowing into the tube covers all bases for effective and sufficient inflation of the life jacket in an emergency.
