You want to see something SAD!?!?!?

I spoke here earlier about how a lot of smoke detectors now use a radioactive source that is potentially DEADLY! I don't know how new the technology is, but it is likely pretty new.

Well, I mused about ANOTHER way of detecting smoke, etc... It is 100% safe, NO RADIATION, etc... Again, I don't know how old it is, but it was around over 50 years ago, and guess who identified the basic theories behind it........ A guy by the name of Thomas Alva Edison! YEP, THAT guy! The guy that came up with the viable incandescent light, and tube.

GUESS WHICH ONE FAILS to save people! GUESS which one DOESN'T fail!

Aw what the hell. The copy buffer DIDN'T have the link. Anyway, they did a test, and found out that photoelectric detectors were better at detecting smouldering smoke before a person would be dead or simply unable to get out. The more common radioactive based ionization detectors took 37 minutes or more, which was over twice as long. If a person were still alive, they may find it hard to navigate to outside of the room..

  • I worked over 25 years in a manufacturing environment. All the smoke detectors I have personally seen in use are of the photoelectric type.

    Must be a reason...
  • i wounder how many people have died from a smoke detector

    • If it fell off the wall and hit you on the head in the right place it might.

  • OK, HERE is an article that explains what I am talking about:

    Photoelectric vs Ionization Smoke Alarms - Deadly Differences

    It says, in part:

    In other words, if you happen to be in a ROOM with a QUICK BURNING fire, an ionizing alarm might save you, MAYBE! In almost any other circumstance, a photoelectric is FAR more likely to save you. If it is a fast burning fire, elsewhere in the house, the PE one will likely go off in time to save you. If it is like what "The vast majority of residential fire fatalities are due" to, the PE one is likely to save you, and you will be a DEAD DUCK with the ionizing type!

  • I remember reading the included manufacturers warranty literature in a certain common brand of smoke detectors. Right there in print the manufacturer stated their smoke detector failed in 30% of fires...

    Let this be your first alert things are not always ideal.
