A gas explosion at a laboratory run by the University of Texas for Advanced Technology in Leander, Texas injured one person last week. The researchers were studying high-velocity projectiles for the U.S. Army when their equipment failed.

The Austin-American Statesman reports that the equipment failure lead to gas being released from a pressurized line. No one inside was hurt, but flying shrapnel hit and injured a passing motorist. The side of the building and the roof sustained major damage.

Nearby businesses were temporarily evacuated as a precaution. UT’s Environmental Health and Safety department will investigate the explosion, the first of its kind for the laboratory since it began 20 years ago.
