Useful Resources

I'll slowly add to the Useful Resources list on the right over the next few days, but the following are pretty good places to bookmark as a start.

NH3 Info - Air Liquide has an excellent page with all the basic Anhydrous Ammonia properties you will likely ever need.

Refrigeration Engineers NH3 forum - A good place to start for newcomers to ammonia equipment troubleshooting.

Refrigeration Engineers and Technicians Association (RETA) - If you have the opportunity to join your local RETA chapter, I would highly recommend it. They also have a fairly decent online training program for your maintenance personnel.

OSHA's PSM - Occupational Safety and Health Administration's PSM guidance

EPA's RMP - Environmental Protection Agency's RMP guidance.

DHS CSAT - Department of Homeland Security's Chemical Security Anti-Terrorism Standard guidance.
