ERPG
Emergency Response Planning Guidelines (ERPG) are developed by the American Industrial Hygiene Association (AIHA).
- ERPG-1 (mild effects),
- ERPG-2 (serious effects), and
- ERPG-3 (life-threatening effects)
ERPGs are intended to protect “nearly all individuals” from each effect level. In establishing ERPGs, acute toxicity data as well as possible long-term effects from a single acute exposure are considered. Adjustments, based on informed judgment, can be made for the increased susceptibility of sensitive subgroups in the general population (EPA 1987, Appendix D).
