Firefighters gave first aid to an elderly man who collapsed after his home became smoke logged during a cooker fire.
Three fire crews from Tring, Berkhamsted and Hemel Hempstead rushed to the home in Friars Walk, Tring, just before 7pm on Tuesday.
Although the fire was already out when they arrived the property was heavily smoke logged so firefighters used ventilating equipment.
The ambulance service was called and the man was assessed but did not need hospital treatment.
Firefighters recorded the blaze as accidental and left just before 8pm.
