HOUSTON --A firefighter was injured after a fire and shelter-in-place at NASA Johnson Space Center. The Houston Fire Department says it was dispatched to a building fire with HazMat at JSC just after 9:30am Monday morning. HFD says a battery was being tested inside a containment system when it overheated and caught some of the insulation on fire. Initially, it was believed that one of the bi-products of combustion could be dangerous so NASA issued a shelter-in-place for the facility. HazMat conducted air monitoring and revised the shelter-in-place to include only the building of origin. HFD said the fire was extinguished just before 11:30am. One firefighter was injured when a hydrant cap blew off and struck him in the knee. There were no other reported injuries.
