The Immediately dangerous to life or health air concentration values (IDLH values) developed by the National Institute for Occupational Safety and Health (NIOSH) characterize these high-risk exposure concentrations and conditions and are used as a component of respirator selection criteria first developed in the mid-1970s.

Until this occurs, this list contains IDLH values based on both the 1994 revised criteria and CIB 66 [NIOSH 2014-100]. It is important to note which criteria was applied to develop a specific IDLH value.

The term immediately dangerous to life or health (IDLH) is defined by the US National Institute for Occupational Safety and Health (NIOSH) as exposure to airborne contaminants that 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 ...

2022年4月25日 · Immediately Dangerous to Life and Health limits (IDLHs) are workplace exposure limits that are meant to protect workers when they are exposed to a toxic chemical in the course of their work. What are IDLHs?

2017年3月21日 · The Documentation for Immediately Dangerous to Life or Health (IDLH) Concentrations is a compilation of the rationale and sources of information used by NIOSH during the original determination of 387 SCP IDLH values.

2019年2月5日 · An IDLH value determines the concentration at which exposure to a chemical without a respirator would cause permanent or escape-impairing health effects.

IDLH is an acronym for Immediately Dangerous to Life or Health, and is defined by the US National Institute for Occupational Safety and Health as exposure to airborne contaminants that is "likely to cause death or immediate or delayed permanent adverse health effects or prevent escape from such an environment."

In determining IDLHs, the ability of a worker to escape without loss of life or irreversible health effects was considered along with severe eye or respiratory irritation and other deleterious effects (e.g., disorientation or incoordination) that could prevent escape.

2019年9月2日 · “Immediately Dangerous to Life or Health” (IDLH) is a term used to describe hazards in which an acute exposure to the hazard poses a severe risk of immediate health damage, injury, or death.

The primary objective of this Current Intelligence Bulletin (CIB) is to present a methodology, based on the modern principles of risk assessment and toxicology, for the derivation of IDLH values, which characterize the health risks of occupational exposures to high concentrations of airborne contaminants.
