What color indicates the MMR is at 1/3 air capacity?

The color that indicates the MMR (Manual Motion Indicator) is at 1/3 air capacity is red. In the context of the Scott Air-Pak X3 SCBA, the MMR uses a color-coded system to provide clear and immediate feedback to the user regarding the remaining air supply. Each color corresponds to a specific range of air capacity: green typically indicates a safe level of air, yellow signifies that caution is needed, and red alerts the user that the air supply is low and that immediate action is necessary. This system is designed to enhance situational awareness for firefighters, allowing them to effectively manage their air supply during emergencies.
