Immediately Dangerous to Life or Health. An environmental condition which would immediately place a worker in jeopardy. Usually used to describe a condition existing where self-contained breathing apparatus must be used.
A concentration of airborne contaminants, normally expressed in parts per million (ppm) or milligrams per cubic meter, which represents the maximum level from which one could escape within 30 minutes without any escape-impairing symptoms or irreversible health effects. This level is established by the National Institute of Occupational Safety and Health (NIOSH).

Immediately Dangerous to Life or Health. A term used to describe an environment which is very hazardous due to a high concentration of toxic chemicals or insufficient oxygen or both.
Immediately Dangerous to Life and Health The maximum level to which a healthy individual can be exposed to a chemical for 30 minutes and escape without suffering irreversible health effects or impairing symptoms. Used as a "level of concern.".
Immediately dangerous to life or health concentrations represent the maximum concentration from which one could escape within 30 minutes without a respirator and without experiencing any escape-impairing (e.g., severe eye irritation) or irreversible health effects.
Immediately dangerous to life and health. Any condition that poses an immediate or delayed threat to life or that would cause irreversible adverse health effects or that would interfere with an individual's ability to escape from the dangerous condition (OSHA 29 CFR 1910.146).
Immediately Dangerous to Life and Health. Maximum Concentration from which one could escape within 30 minutes without any escape-impairing symptoms or any irreversible health effects.
Immediately Dangerous for Life or Health .
Immediately dangerous to life or health. A term used to describe certain very hazardous environments, usually with high concentrations of toxic chemicals, insufficient oxygen, or both.
Immediately Dangerous to Life and Health, the airborne concentration below which a person can escape without respiratory protection and exposure up to 30 minutes, and not suffer debilitation or irreversible health effects. Established by NIOSH.
Immediately Dangerous to Life and Health (set by the U.S. National Institute of Occupational Safety and Health, NIOSH), the maximum concentration of airborne contaminants, normally expressed as parts per million (ppm), from which one could escape within 30 minutes without a respirator and without experi- encing any escape impairing (e.g., severe eye irritation) or irre- versible health effects
The Immediately Dangerous to Life or Health air concentration values, developed by the National Institute for Occupational Safety and Health (NIOSH), are intended to describe situations "that pose 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."
Immediately dangerous to life and health. Note: Choose a respirator for toxic vapors that allows 30 minutes to escape maximum concentrations without escape-impairing symptoms or irreversible health effects.
Immediately Dangerous to Life and Health - The maximum concentration of gas (in PPM) from which a worker could escape within 30 minutes without experiencing any escape-impairing or irreversible health effects.
Any situation deemed Immediately Dangerous to Life and Health. More narrowly defined by OSHA. See main IDLH article. An area of maximum danger to firefighters.
Concentrations immediately dangerous to life and health. An atmospheric concentration of any toxic, corrosive or asphyxiant that poses an immediate threat to life or would cause irreversible or delayed adverse health effects or would interfere with an individual's ability to escape from a dangerous atmosphere. (29 CFR 1910.120)
An IDLH is a situation Immediately Dangerous to Life and Health, defined by the NIOSH as follows: "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." Examples include smoke or other poisonous gases.
