Abstract
The immediately dangerous to life or health (IDLH) air concentration values have been recommended by the US National Institute for Occupational Safety and Health (NIOSH) as respirator selection criteria. The current NIOSH definition for an IDLH condition is a situation "that poses a threat of exposure to airborne contaminants when that exposure is likely to cause death or immediate or delayed permanent adverse health effects or prevent escape from such an environment." NIOSH's stated purpose for establishing IDLH values is to "ensure that the worker can escape from a given contaminated environment in the event of failure of the respiratory protection equipment." The complete introduction and documentations to the 398 existing IDLH values can be read or downloaded at the NIOSH Internet website. At the time of writing, NIOSH is reconsidering several aspects of the IDLH definition and the criteria used in developing IDLH values.
