Current through Register Vol. 48, No. 12, March 22, 2024
a) Nitrogen fertilizer solutions are divided into subcategories as follows:
b) In the interest of safety, personnel storing and handling nitrogen fertilizer solutions should be knowledgeable in the safe control and handling of these solutions. The Department conducts a training program in nitrogen safety procedures.
c) Ammonia vapor has a pungent odor which serves as its own warning agent. Ammonia vapor is lighter than air. Out-of-doors handling and adequate ventilation are best means of preventing accumulation. The flammable limits to free ammonia are from 16 to 25 percent by volume in air. Experience has shown that ammonia is extremely hard to ignite in spite of these theoretical limits and is generally considered to be a non-flammable gas. Ammonium nitrate starts to decompose at temperatures above 410 degrees F. Welding should not be attempted on any system which has contained nitrogen fertilizer solutions without proper preparation (see 8 Ill. Adm. Code Section 215.Table D).
