Exiting the IDLH environment

摘要

We feel compelled to respond to comments by Battalion Chief (Ret.) Chuck Smeby in Letters to the Editor (Fire Engineering, March 2009). Smeby was responding to a letter from Assistant Chief (Ret.) Gary P. Morris relating to air management. Smeby seems to advocate that firefighters operate in the hazard area until their low-air warning alarm activates, whereas Morris advocates firefighters follow the basic premise of air management that they should be out of the hazard area before the low-air warning alarm activates.
