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.

Appendix E: Supplemental Risk Management Program Guidance for Ammonia Refrigeration Facilities

Additional information for food processors, food distributors, refrigerated warehouses, and any other facility that has an ammonia refrigeration system. Includes details on exemption for farms, threshold quantity, and offsite consequence analysis.

Chemical Safety Alert: Hazards of Ammonia Releases at Ammonia Refrigeration Facilities

Anhydrous ammonia is used as a refrigerant in mechanical compression systems, often liquefied under pressure which increases exposure risk due to potential for rapid release into the air as a toxic gas.
