What does one red light indicate on the SCBA night fighter system?

One red light on the SCBA night fighter system signifies a flashing air supply at 25%. This is an important safety indicator because it alerts the user that the air supply is critically low, and immediate action is needed to ensure the safety of the user. It serves as a warning that the user should begin to plan for exit or a refill to avoid running out of air during critical situations.

In emergency and hazardous environments, being aware of air supply levels is vital for maintaining operational safety, as low air supply can compromise the user’s ability to breathe and function effectively. The flashing aspect of the red light is crucial as it draws attention, prompting users to take necessary preventive measures to avoid potential danger.
