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.

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.

Risk Management Program (RMP) Reporting Center

The Center can answer any questions you have about the RMP*eSubmit reporting software, or EPCRA Tier2 Submit software.

Underground Transport Restoration (UTR) Operational Technology Demonstration (OTD)

This full-scale study focused on gathering sampling, decontamination (decon), waste management, and cost analysis information for the remediation of a subway system after contamination with a Bacillus anthracis (Ba) surrogate.

RMP*Comp

You can use this free software program to complete the Off-site Consequence Analyses (both worst case scenarios and alternative scenarios) required under the Risk Management Program rule, so that you don't have to do calculations by hand.
