Takeaways
The UL 217 standard governs the manufacturing of smoke alarms in the United States.
The standards process involves a committee with representatives from manufacturers, academia, and the public.
Manufacturers can block changes to the standard, which has hindered progress in improving smoke alarm technology.
The current standard allows for both ionization and photoelectric smoke alarms, but there is a push for greater adoption of photoelectric alarms.
Changes to the standard can be delayed, leading to a delay in the implementation of improved smoke alarm technology.
Advocacy and education are crucial in promoting the use of photoelectric smoke alarms and improving consumer safety. Ionization smoke alarms have flaws and are prone to nuisance tripping.
Photoelectric smoke alarms are more effective in detecting slow-moving, large particles in real fires.
There is ongoing debate and resistance from manufacturers in updating the UL standards for smoke alarms.
Lawsuits against companies like KIDDA and First Alert are pressuring them to improve their products.
Using photoelectric smoke alarms is crucial for better fire safety.
