Which of the following is NOT part of the preflight inspection of the escape slide on the ERJ 175?

The preflight inspection of the escape slide on the ERJ 175 includes several crucial checks to ensure that the slide is ready for emergency use. This inspection focuses specifically on the equipment directly related to the escape slide system.

Checking the pressure gauge and ensuring that the gauge needle is in the green zone are essential steps to confirm that the escape slide is properly inflated and ready for deployment. Visual checks for damage are also critical, as they allow the crew to identify any physical issues that could impair the functionality of the slide.

Inspecting oxygen masks, while an important safety procedure, does not pertain to the escape slide itself. Oxygen masks are part of a different emergency system within the aircraft, meant for individual passenger use rather than for the escape mechanism. Therefore, it is not included in the preflight checklist specifically for the escape slide.
