"Hot" LED
A sensor at the end of ladder or pole extensions, that lights at contact with live power. | |
I'd like to see "HOT" LEDs on things like metal ladders, so you'd know not to climb on them at construction sites.
Smoke sensing on the extensions of ladders makes sense also, so you'd know the conditions in the upper space before you climb.

I think it'd be better if it could detect the presence of an electrical field before contact with the actual power source. |

This would be good for scaffolding as well. (if that's not what you mean by pole extensions). |

I worked on a fashion event staged in a circus tent many years ago. I was unimpressed to discover that the main supporting pole was live. This is a great concept that could do with some more research (a la Bristolz' suggestion). |

Ladders for electrical work or for working around electrical equipment are constructed from non-cunductive materials such as fiberglass or wood. These are redily available at your local home store and would be a better way to prevent electrocution. Fishbone for comming up with a way to keep stupid people from killing themselves. |

Shucks. I was so hoping that (a way to keep stupid people from killing themselves) wouldn't happen. Regardless, an O2 sensor might also be useful. |

Hells bells, I think I'll just reinvent this as the "21st Century Canary on a Stick". |

[ato_de], Even "haughty intellectuals" get tired & don't think clearly all of the time. |

Yep. (pulls tab) Too dark in here to flip the "watch you back" switch. Man, where's the light? sip. |
