The number 1 failure that causes releases of anhydrous ammonia in agricultural and bulk transports is hose failures! Without a doubt, at a fertilizer distribution center, loading and unloading DOT containers via transfer hoses pose the greatest risk for a catastrophic event. So special attention is deserving when it comes to the hose(s) we will use for these transfers and in my nearly 30 years of working with NH3 hoses I have seen some real “doosey” of hoses that I would not have used to water my lawn, much less use for transferring NH3! So what should we look for in a loading/unloading hose?
