Chemical Emergency Preparedness and Prevention Advisory: Ammonia

This advisory recommends ways Local Emergency Planning Committees (LEPCs) and chemical facilities can minimize risks from this extremely hazardous substance, especially when present in excess of its 500 pounds threshold planning quantity.

Technical Background for Offsite Consequence Analysis for Anhydrous Ammonia, Aqueous Ammonia, Chlorine, and Sulfur Dioxide

Presents the methodology and assumptions used to develop the chemical-specific tables for accidental releases of these toxic vapors, as required by the Risk Management Program.

Chemical Safety Alert: Anhydrous Ammonia Theft

This extremely hazardous substance is largely used as an agricultural fertilizer, but is also a key ingredient in the illegal production of methamphetamines. It is stored as a liquid under pressure, but becomes a toxic gas when released.
