HOUSTON, July 25 (Xinhua) -- A shelter-in-place was ordered after a battery caught fire during a testing at NASA's Johnson Space Center Monday morning.

A battery was being tested inside a containment system when it got overheated and caught fire at about 9 a.m. local time, ABC quoted the Houston Fire Department (HFD) sources as reporting.

A shelter-in-place was issued for a few buildings because it's believed that one of the bi-products of the combustion could be dangerous, HFD said.

The fire was put out before 11:30 a.m.

A firefighter was injured when a hydrant cap blew off and struck him, according to ABC.
