The Marshalltown Fire Department was called out to the 700 block of Union Street on Sunday to a fire in a second floor bedroom at that location.
Acting Fire Chief Scott Johnson says everyone in the residence got out safely.
He says the fire was contained to the bedroom area and the loss was estimated at 500 dollars.
Acting Chief Johnson says the fire was blamed on a discarded cigarette in a mattress.
He did say that one of the occupants did suffer burns to the hand and had to be treated at M-M-S-C.
