Slim Jim Explosion: How Harmful is Ammonia?
June 10th, 2009. By admin
This week’s explosion at Con-Agra’s Garner, NC Slim Jim plant has ammonia in the spotlight—it’s used in their meat refrigeration process. As reports continue to show rescue workers suiting up in protective gear given the risks associated with ammonia exposure, it’s worth taking a look at just what is ammonia and how much of a risk does it pose when used commercially?
According to the Agency for Toxic Substances and Disease Registry (ATSDR), which is part of the U.S. Department of Health and Human Services, ammonia is a clear gas at room temperature—and it’s characterized by that powerfully pungent odor you’re familiar with from household cleaners (and that you know in an instant cannot be good for you). Under pressure, anhydrous ammonia becomes a liquid. Of note, the ammonia you find in household cleaners is typically at a concentration of about 5% to 10% (weight:volume) compared to as much as 25% or more for commercial use.

- The Department of Transport does not classify ammonia as a flammable substance, however, the ATSDR, OSHA and NIOSH all say that it should be treated as one.
