A Houston-bound British Airways plane was forced to land at O'Hare International Airport Sunday afternoon after the pilot reported a situation onboard. The landing prompted a Hazardous Materials response by the Chicago Fire Department.

An EMS Plan 1 and Level 1 HazMat was called on an O'Hare runway at 2 p.m. as an electrical precautionary measure, according to Fire Media Affairs Cmdr. Will Knight, who said all passengers from the plane were cleared and there were no injuries.

British Airways Flight #195, which originated in London and was headed to Houston, was diverted to O'Hare after the pilot reported a "situation" onboard, according to Dept. of Aviation spokesman Gregg Cunningham.

The Dept. initially received word from the pilot about the diversion at 1:20 p.m. and the plane landed safely at about 1:45 p.m., Cunningham said.

All passengers were de-planed onto the tarmac and taken onto buses to Terminal 5, Cunningham said.

Cunningham did not know the specifics of what situation prompted the diversion.

Fire crews were investigating a potential "flammable" in a cargo area of the plane, according to unconfirmed fire dispatch reports.

Crews remained at the scene at 2:30 p.m.
