What should be done as part of the smoke fire fumes memory items?

Donning supplemental oxygen is critical during a smoke, fire, or fumes scenario because smoke inhalation can be extremely dangerous and can impair the ability to think clearly and function effectively. By using oxygen, pilots can help maintain cognitive function and physical performance even in compromised environments. This action is aimed at preserving the crew and passenger's ability to handle the emergency effectively.

The situation typically mandates a rapid response to ensure that those on board can breathe adequately and remain oriented to manage the situation. The administration of oxygen is a fundamental step in mitigating the immediate dangers associated with smoke or fumes in the aircraft, allowing the crew to focus on subsequent procedures necessary for dealing with the emergency.

In the context of aviation safety protocols, addressing cabin air quality is paramount before taking further steps, such as activating fire suppression systems or notifying ground control.
