Final Answer:
The correct answer is B) Twice. Pulling the life jacket toggle twice ensures proper inflation and is a crucial step in the safety demonstration for air travelers. Thus the correct answer is B) Twice.
Step-by-step explanation:
During a safety demo on an aircraft, the standard procedure for pulling the life jacket toggle involves doing it twice. This action is crucial for inflating the life jacket, ensuring its proper deployment and readiness in the event of an emergency. The two pulls activate the inflation mechanism and allow the wearer to have a fully functional and buoyant life jacket.
The double pull is designed to provide redundancy and reliability. In emergency situations, having a fail-safe mechanism is essential, and the two-step process of pulling the toggle helps ensure that the life jacket inflates as intended. This redundancy is a safety feature, reducing the risk of a single-point failure.
Passengers are typically instructed to pull the toggle once, wait for inflation, and then, if needed, pull it a second time to ensure the life jacket is fully inflated and operational. This attention to detail in the safety demonstration contributes to the overall safety and preparedness of passengers in the event of a water landing or emergency evacuation involving the use of life jackets.
