Upon firefighters arrival, white smoke was showing from the building. The fire was contained to the vaccuum unit, which suffered major damage. The building itself was undamaged.
Firemen received the call at around 8:33 am informing them workers were evacuating the building. They were on scene for about an hour and a half.
