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 revised IDLH for dichloromonofluoromethane is 5,000 ppm based on acute inhalation toxicity data in animals

May 10, 2019 · IDLH values are established (1) to ensure that the worker can escape from a given contaminated environment in the event of failure of the respiratory protection equipment and (2) to indicate a maximum level above which only a highly reliable breathing apparatus, providing maximum worker protection, is permitted.

Ingestion : Immediately flush eyes with plenty of water, occasionally lifting the upper and lower eyelids. Check for and remove any contact lenses. Continue to rinse for at least 10 minutes.

Rapidly or completely vaporizes at atmospheric pressure and normal ambient temperature. Normally stable, even under fire conditions. Methane is a colorless odorless gas. It is also known as marsh gas or methyl hydride. It is easily ignited. The vapors are lighter than air.

GHS02. GHS04 Signal Word (GHS-US/CA) : Danger Hazard Statements (GHS-US/CA) : H220 - Extremely flammable gas. H280 - Contains gas under pressure; may explode if heated. May displace oxygen and cause rapid suffocation.

Apr 25, 2022 · 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?

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 ...
