Can an ambient air pump be used for confined space respiratory protection?
A. Those confined spaces deemed IDLH (Immediately Dangerous to Life and Health) environment require an SCBA or an airline respirator with an escape bottle. These model Escape bottles normally require a high-pressure/pressure-demand breathing system. An AABA (ambient air breathing apparatus) is a low-pressure, constant-flow product. Therefore, the high-pressure escape bottle and the low-pressure AABA will not work together.
