Immediately dangerous to life or health (IDLH)
An IDLH level represents the maximum airborne concentration of a substance to which a healthy worker can be exposed for as long as 30 min and still be able to escape without loss of life or irreversible organ system damage. IDLH values also take into consideration acute toxic reactions, such as severe eye irritation, that could prevent escape.
