On Tuesday (29) at 12.55pm, one crew from Huntingdon and two crews from St Neots were called to a flat fire on Park Lane, Godmanchester.
Crews arrived to find smoke issuing from a first floor window and a fire in the bedroom of the property.
Wearing breathing apparatus, firefighters used two hose reels to extinguish the fire, before dampening down the area.
One person was taken to hospital for smoke inhalation.
The flat was safely evacuated and all persons were accounted for.
All crews returned to their stations by 3.10pm.
The cause of the fire was accidental.
St Neots Watch Commander, Jon-Paul Jones who attended the fire commented:
"Thankfully the resident had a working smoke alarm which alerted them to the fire, and a neighbour quickly called the Fire Service.
"Without a working smoke alarm and the quick-thinking of a neighbour, this fire could have been much more serious.
“A smoke alarm is the single most important thing you need in your home - it will alert you to a fire and give you precious minutes to escape to safety.
"The crews did a fantastic job to tackle the fire and bring it under control so quickly.”
