A flash fire at the Sinclair oil refinery injured four employees, including three in critical condition at a Colorado hospital.
The flash fire occurred about 10:20 a.m. inside a gas recovery unit on the east side of the oil refinery, said local Sinclair spokesman.
Three of the four injured were flown to the burn center in Greeley, and one was treated and released locally.
This incident at the refinery brings up the age-old debate about safety in a refinery.
An investigation is being launched to better understand why the fire occurred in the first place.
This incident is being investigated to understand what happened and come up with corrective actions to prevent it from occurring again. Two investigators from Occupational and Safety and Health Administration (OSHA) were sent to the scene to investigate the incident.
