August 18, 2022, at 3:00 p.m., an employee entered an empty liquid propane gas (LPG) tank for servicing at an industrial equipment wholesaler facility. Earlier in the day, the employee approached a supervisor and said he wanted to enter the tank to spray Torq CB III penetrating oil product on an internal valve to loosen it overnight so it could be worked on the next day. The supervisor told the employee to wait until the next morning when the tank could be vented.
