The smoke "was due to a malfunction of a heating unit in the library. Power to the unit was shut down and smoke was cleared from the library," said a statement posted at Hamlet Hub from Ridgefield High principal Stacey Gross.
The Ridgefield Fire Department checked the building and allowed students and staff to re-enter the building by 7:35 a.m., Hamlet Hub said.
