Welded Repairs on Nurse Tanks

About this Document

Catastrophic results can occur when unauthorized repairs are performed on high pressure vessels transporting anhydrous ammonia (NH3). An improper weld on a nurse tank was a factor in a nurse tank failure that occurred on April 15, 2003 near Calamus, IA. resulting in one fatality and one serious injury. This is a stark reminder of the serious consequences that can occur as a result of a nurse tank failure.
