How long before exit can jumpers remove their mask/cannula/oxygen?

• A. 15 seconds prior to exit
• B. 30 seconds prior to exit
• C. 45 seconds prior to exit
• D. 60 seconds prior to exit

Answer: (B)

Jumpers can remove their mask, cannula, or oxygen 30 seconds prior to exit. This timing is critical to ensure that jumpers have adequate oxygen levels for their descent but can also prepare effectively for the jump. Removing the equipment too far in advance could lead to reduced oxygen levels, which could impair performance. Conversely, waiting too close to the exit may not provide sufficient time for jumpers to adjust and ensure a successful and safe jump. Therefore, the 30-second mark strikes an optimal balance, allowing jumpers to maintain necessary oxygenation and complete pre-jump checks efficiently while preparing for the actual jump.
