How can oxygen masks be manually deployed?

Manually deploying oxygen masks is best accomplished through the use of a switch or by inserting an object into the compartment designed for that purpose. This method is specifically intended to activate the release mechanism and ensure that the oxygen masks are available for use in an emergency situation.

The design of the compartment often includes features that require deliberate action to deploy, which ensures that the masks are securely stored until they are actually needed. Implementing a mechanism like a switch provides clarity and ease of use, especially under stressful conditions, which is crucial for the safety of passengers and crew.

The other deployment methods, such as shaking or pulling a lever, are not reliable or consistent with standard safety protocols, as they may not activate the deployment system effectively. Thus, utilizing a switch or functionally inserting an object reflects the best practices and safety standards in aviation safety measures.
