📕 THE HOME HAZARD FILES — 100 field notes on what actually starts house fires, and what each fix really costs: https://home-hazard-files.netlify.app The smoke alarm on your ceiling looks fine — but not every alarm works when it matters. Over the past several years, millions of smoke alarms have been recalled in the U.S. for one chilling reason: they can fail to sound during a real fire. Some are cheap online no-names; some are made by the most trusted brands (specific recalled models — not the brands themselves). Many are still on ceilings right now. This video counts down 7 smoke alarms you should never rely on — with exactly how to check the one over your head — and then the 3 things that make an alarm you can actually trust with your life. Go and check yours after watching. This is general safety information based on CPSC recalls and fire-safety guidance. If you find a recalled model, do not take the alarm apart — contact the manufacturer for a free replacement, and keep using it until the replacement is installed. Replace any alarm over 10 years old.
