Firefighters saved a central Whanganui villa from worse fire damage because the three people inside were alerted by a smoke alarm.
The fire started in the wall of the Bell St villa just before 11pm on August 14, acting station officer Geoff Moore said.
The family were in the bedroom when the smoke alarm went off and they went outside and rang Fire & Emergency NZ.
Another person sprayed water on the fire with a garden hose.
The prompt arrival of two appliances probably prevented the whole house going up, Moore said. Because the fire was in an outside wall it could also have spread to the house next door.
