No WHY

I know I have posted this before but......99.62% survival with HW smoke and co....rockets to 99.87 when you add sprinklers....If you really want to save lives, mandate HW interconnected smoke and CO at some reasonably low threshold in all new and existing homes. Don't just save the people in the new homes, the fires are not nearly as frequent there (at least around here).

I would like to get a copy of the study or report in you photo. Do you have a web link or pdf?

I believe you'll find that the 99.62% survival rate is where HW smokes and CO detectors operated, not where they were installed. The significant difference is that FD's daily see a significant number of detectors disabled due to false alarms or failed to operate due to age. Your link didn't reveal the study, but I'll look for it, as I'm interested to know the actual numbers of fires that stat is based on. Sadly, even HW detection requires some human interaction and are easily disabled, unlike sprinklers that for the most part require no occupant interaction.

Except that water valve that magically gets turned off.
