Safety apparatus for protecting living creatures from the effects of accumulated combustion products (such as carbon monoxide and/or smoke) in an enclosed or confined space comprising a combustion product detector (4), a combustion product extractor (6), and an audio or visual alarm (8). The extractor (6) may be an extracts on fan, which is activated in response to detection of combustion products by the detector, and which moves the combustion products from the space within which the combustion products have been detected to the external atmosphere so that the combustion products may disperse. The extractor, when actuated, may operate for a predetermined period of time, for example thirty minutes, or it may operate until the detector no longer detects the combustion products.
