The Charleston Fire Department was called 11:29 a.m. Tuesday to Old Main because of a steam pipe issue in the basement mechanical room.

Captain James Calvert said some steam pipes in the basement mechanical room increased the heat faster than what the fire detector would allow, triggering the fire alarm.

The fire department silenced reset the alarm and Environmental Control was going to Old Main to take care of the steam pipe issue and investigate why there was a higher than normal temperature.

Calvert said there was no danger to anyone or any damage done to the building.

He said the thermal imaging cameras registered a heat in the room of about 200 degrees.

The alarms reactivated around noon after CFD units left Old Main, prompting their return.
