When the whistle sounds whilst using a SCABA set approx 30 minutes of time left for escape?
Direct Answer
Option B: False
The low-pressure warning whistle on a Self-Contained Breathing Apparatus (SCABA) typically activates when the cylinder pressure drops to a reserve level, usually providing only 5 to 10 minutes of air. This is intended for immediate withdrawal and escape, not a 30-minute duration, which would exceed the remaining air capacity.
