At 5.43am four fire trucks, a support vehicle and a specialist appliance rushed to the scene of a well-involved blaze at a two-storey residential property on Girrahween Dr in Totara Vale, Albany.
Hato Hone St John responded with two ambulances and two rapid-response vehicles.

“This is a two-storey house and the top floor of the house is well-involved.”
