Where there’s smoke …
Stand-alone smoke alarms do two things: they detect smoke, and alert the occupants to the danger of fire.
They are called stand-alone because they run off batteries rather than being powered by mains electricity.
These alarms must meet ENNS Standard 14604, weighing in at less than 200 grams. The plastics they are made of, usually ABS and polypropylene, account for between 55 and 60% of their weight.
In France, Executive Order 2011-36 of 10 January 2011 published in the Official Gazette of 11 January 2011 requires all residential premises to be fitted with stand-alone smoke alarms from 08 March 2015. At present, only 2% of homes have them, compared to 98% in Norway and 89% in England.
In the U.S., where 96% of homes are fitted with at least one stand-alone smoke alarm, it is estimated that 63% of house fire deaths occurred in homes not fitted with smoke detectors (2007 figures), and that for all homes to be fitted with stand-alone smoke alarms would save 898 lives each year.
In the Republic of Ireland, 66% of house fire deaths occurred in homes which had no (or not-working) stand-alone smoke alarms (Fire Service Statistics 2007).
