Fire crews were called to a carbon dioxide leak on Thursday in Milton Keynes
Fire crews were called to an address on Eaton Avenue, Bletchley at around 6:36pm on 27th January.
Two appliances and crews from West Ashland attended, along with an officer.
The firefighters used two sets of breathing apparatus, a gas monitor and they isolated the gas supply, ventilated the property and provided advice.
Bucks Fire and Rescue said: "Carbon Monoxide is a poisonous gas that has no smell or taste, as a result some refer to it as the silent killer.

Carbon monoxide poisoning occurs when a fuel burning appliance such as a boiler, gas or open fire has not been properly installed, maintained or ventilated. 200 people are hospitalised in the UK every year with carbon monoxide poisoning.
