Nitrogen leaks at Temple University engineering building
PHILADELPHIA (AP) — Philadelphia hazardous materials crews were called when nitrogen was found leaking from a tank in Temple University's engineering building.
School spokesman Brandon Lausch says housekeeping personnel heard the tank leaking about 4:20 a.m. and notified authorities.
Philadelphia fire department, hazmat and environmental health officials responded.
They tested the air quality, and determined there was no hazard, so the building opened normally later Wednesday morning.
Nobody was hurt.
Lausch says the tank was emptied of whatever nitrogen it contained. It wasn't immediately clear why it leaked.
