What happens if the far left (red) light is flashing rapidly (10 times per second)?

When the far left (red) light is flashing rapidly at 10 times per second on the Scott Air-Pak X3, it indicates a critical warning related to the user's safety. This specific alert typically signifies that the air supply is dangerously low or that there is an imminent hazard in the environment that requires immediate action. In such situations, the appropriate response is to immediately leave the hazardous atmosphere.

This quick evacuation is essential to ensure safety, as remaining in a dangerous environment could lead to serious health risks or incapacitation. The other response options, although they may seem reasonable in different contexts, do not align with the urgency indicated by the rapid flashing light. Evacuating promptly allows for a safer approach to reassessing the situation from a secure location.
