Explosion Occurs after an Analyzer Is Repaired

The instrument mechanic replaced the fluid in the bubbler with glycerin. Unfortunately, the glycerin reacted with the gas, turned into nitroglycerin, and detonated. The explosion seriously and permanently injured the employee. This dangerous accident resulted from an undetected one-minute process change of less than a quart (1 I.) ol lluid. It appears that a lack of proper training led to this accident.
