This week’s video is a bit dated, but it is an EXCELLENT video for those who work around Anhydrous Ammonia (NH3). It contains video showing just how hard it is to ignite NH3 outside, although there are flaws with their “testing methods”. And it also contains scenes that may be upsetting to some, as it has live news footage from the 1984 Shreveport, LA FD fatality involving the ignition of NH3 vapors. Anhydrous Ammonia WILL BURN – it takes (depending on who’s document you are reading) 150,000-160,000 ppm (15%-16%) to burn, but it WILL BURN.
