The Brenham Fire Department was called out four times on Tuesday. Around 7:45 a.m., units were dispatched to Stanpac USA, 801 Mangrum Street, for a fire alarm. Firefighters learned that the exhaust fan caught fire above the stove, causing a smell inside the home. At 2:45 p.m., units responded to a home in the 1500 block of Plymouth Lane for a smoke detector going off. They arrived to find a bad smoke detector and replaced it before clearing the call.
