A report in 2017 by the National Fire Protection Association (NFPA) recorded a likely average annual death rate for home fires involving oxygen administration equipment of 70 people (or 3% or all home fire deaths), based upon figures between 2011 and 2015. The NFPA also reports that US hospital emergency rooms deal with an average 1,190 cases of burns each year as a result of home oxygen fires and that these fires or burns are becoming more common. It also notes that these figures are “likely underestimates”.

However, the issue isn’t about the level of risk anymore, firebreaks are now a standard requirement.
