Oxygen masks are crucial safety devices found on every flight and are recommended for use during emergencies. However, many people are curious about how these masks work and how long they can deliver the necessary oxygen. The answer is provided in the article below.
Before every flight, airline attendants give passengers a briefing on how to use the oxygen mask and when to use them. These masks are typically located above each passenger's seat and will deploy automatically if there is a sudden change in the cabin pressure.
When learning about the mechanism behind these oxygen masks, many people are often surprised. The oxygen masks on airplanes are not connected to any oxygen supply or compressed air source. They work based on a smart principle that ensures they serve their emergency function in case of an aircraft malfunction.
Scientists explain that these oxygen masks are connected to a chemical compound which, when ignited, produces oxygen gas. This compound typically consists of a mix of barium peroxide (BaO2 – a powder used in fireworks), sodium chlorate (NaClO3 – a component in herbicides), and potassium chlorate (KClO3 – reacts vigorously with sugar).
Therefore, during the safety briefing, flight attendants always emphasize that passengers should pull the mask firmly. This is because the chemical reaction that ignites the substances in the bag attached to the mask is triggered by this strong pull.
With the calculations and designs of scientists, the oxygen mask on an airplane can supply enough oxygen for one person for approximately 12-20 minutes, with an average duration of around 15 minutes.
Many might feel concerned upon hearing this time frame and assume that 15 minutes is too short for using the mask. However, there’s no need to worry, as experts confirm that this duration is enough for the pilot to bring the plane to a safe altitude, where oxygen masks are no longer necessary.
Additionally, aviation experts advise that you could be in danger if you lack oxygen for more than 30 seconds. Without oxygen in the cabin, passengers could experience headaches, dizziness, and even risk losing consciousness, making it essential to put the mask on quickly. Therefore, as soon as the oxygen mask deploys above you, it is crucial to use it promptly and correctly to ensure your safety.
Another important thing to keep in mind is that you should remain calm and focus on putting your oxygen mask on first, before assisting others, even if they are family members. You need to be alert and healthy in order to help others effectively.
Passengers do not need to wear the oxygen mask for the entire flight. Once the plane has descended to a safe altitude, the crew will announce that it's safe to remove the masks, and you can take them off.
