Just hours after a blast at the Redstone Arsenal in Alabama, the refinery in San Antonio exploded. The San Antonio refinery fire was started when a nearby 18 wheeler pickup truck blew up. The18 wheeler was filling up with fuel when its blast began a chain response of explosions that lasted for more than 45 minutes. The fire is still burning up and most nearby firefighters are at the scene to try and put out the fire. This specific refinery was sited 13 times in 2007 by OSHA for safety violations, it nearly makes you question what caused the truck to blow up in the first location.
