This guy appears to be doing a lot of demos, perhaps you can get him.here is a sample of his work.

If either of you - Ted and The Other Brian - or anyone else can put together either presentation they'd both be great for Compliance 101. Any takers?? Only one comment in that there's no ketchup on Chicago style hot dogs!!

(I recommend not using Chicago style dogs <https://en.wikipedia.org/wiki/Chicago-style_hot_dog#/media/File:Chicago-sty le_hot_dog_2.jpg> . The ketchup and mustard are bad enough, but that neon green relish makes a real mess during testing.) But seriously, raw hotdogs work for showing how different situations could cut the skin on a finger. Another potential demonstration is to show how the K factor of a fan relates to injury. My hypothetical test would be to use a set fans with varying K factors. You could use the aforementioned hotdog or people who have signed a waiver. I wouldn't recommend allowing participants to test any fan with a K factor more than 25% of the finger safe limit. That should be sufficient to give an idea of what the K factor means. It may be interesting to take a fan with a K factor just within the finger-safe limit and stick a hotdog in it to show what happens. More than a decade ago, I took an HBSE course from UL that included leakage current video. It appeared to be from the 1950s and it started with a notice that the video was in the public domain. However, I've never been able to find a copy on the web. In the video, the person giving the demonstration cuts the ground plug off of a metal power drill and holds it in his hand. (This was long before double insulated power tools.) The person than put a metal cuff around their forearm just below the elbow. An assistant adjusted the current flowing through the presenters arm from the cuff to the drill. increasing it in steps to 8 mA with the presenter explaining what he feels. At 8 mA, the presenter was losing control of the musculature of the forearm, but he was still able to stand up and clearly describe the situation. I don't know if UL still has this video. If so, it is another question whether they would present it again or share it. Personally, I would rather not create a modernized version. I've experienced 3.5 mA between two fingers on one hand and that is more than enough of a test for me. The opinions expressed are my own and do not necessarily reflect those of my employer. Do not try this at home, and consult your corporate attorney before even considering any demonstrations using humanb subjects. I am proposing hypotheitical demonstrations and I am not specifically endorsing the use of human subjects.

What protective measure can be use in different cases to "lower the risk to an accessible level"? How bad of boo boo are you willing to let your Users have access too? At some point, someone is going to have to stick their finger in there and see how bad it hurts. I'm thinking about using one of those pain charts they use at the hospital. I'd go to a demonstration like that.

I did the Electric Shock for Dummies pitch last year and had a great group attending. I'm willing to do it again this year, building on last years session with some improvements. :>) br, Pete Peter E Perkins, PE Principal Product Safety Engineer PO Box 23427 Tigard, ORe 97281-3427 503/452-1201 fone/fax [email protected] <mailto:[email protected]> From: John Allen [mailto:[email protected]] Sent: Sunday, August 23, 2015 4:40 PM To: [email protected] <mailto:[email protected]> Subject: [PSES] PSES Symposium 2016 - Compliance 101 Track Hi guys, I'm heading up the Compliance 101 Track for the 2016 Symposium in Anaheim, CA. The Track was very well received last year and I'm hoping to do it again this year with 6 or 7 presentations on high level compliance issues, tips and teachings. The audience for the Track are those new to compliance and designers who don't have the time to get their hands around compliance. Believe it or not, some people that attended the Track last year still thought UL was a government agency. I believe we have a huge opportunity to grow the Symposium, and membership in the PSES by teaching newbies and designers how to do what we do. For the consultants out there I know this sounds like you're giving away free consulting, and you are, but as one of you I can say it is worth it - a knowledgeable client is our best client!! The Symposium is not until May 16-18, 2016 but we need to get organized as the TPC is already meeting monthly. Please consider doing a presentation and reach out to me if your interested. If you'd like to see the Compliance 101 presentations to get a flavor for what they looked like let me know. Not 100% sure if I can pass them on if you didn't attend the symposium, but can certainly pass along something similar to the one I did.
