Almost any other system is either going to be very expensive or contain
another toxic substance that will cause other problems.  My suggestion is to
bite the bullet and do the RMP.  I worked with a brewer in Texas before and
it turns out that the RMP for a brewery is fairly simple and not terribly

Also, have your client look at installing monitors -- that is, prestationed
unmanned fire nozzles, with heavy misting capability, as a mitigating
measure.  They are not terribly expensive and can be very effective in
knocking down anhydrous ammonia.
