On Tuesday (30) at 10.24am one crew from Huntingdon and one crew from Thrapston, (Northamptonshire Fire and Rescue Service) were called to a house fire on Loop Road, Keyston.
Wearing breathing apparatus, firefighters used a hose reel to extinguish the fire, before using a positive pressure ventilation fan to clear the smoke.
Both crews returned to their stations by 1pm.
A fire service spokesman said: “The fire was started by incense sticks that had been left unattended.
“Incense and candles can be dangerous if left unattended so always ensure they are placed in a draught-free area, well away from curtains, furniture or other flammable surfaces.
"Make sure you leave plenty of space around the area and ensure that the surface is flat and stable.”
