Small Laser / Indoor User Safety Certificate
0-500 mW take simple test and 4 math problems. no practicum, maybe set in on 4 hour class. Very Basic, covers things leading to help getting variance/HSE etc permits.Stuff you want to know anyways. When is my laser a hazard, and what can I do about it? Covers club and Dj users who average less then 500 mW, most hobbyists, and the pointer guys. Mentions little things like safety cables for bounce mirrors and what should be in a preshow checklist. How much goggle OD do I need, whats a master shutter, laser classifications, emission indicators, Is DMX safe for pyro etc. Basic stuff that gets asked again and again here at PL. Groundwork for getting hired either as self employed weekend warrier, or a start for the big laser company. You'll be happy after you take this test and a lot more comfortable if CDRH/HSE/DIN/WHATEVER comes for a visit. Be your own LSO and not sweat it.
comes with a bunch of PDF study guides, maybe a youtube vid or two.
Large Laser / Outdoor User Safety Certificate
500 mW and UP, Outdoors, Q switched, Pulsed, Or Audience Scanning where allowed. Lasers in Airspace. Big Iron. Lasers that need to be on forklifts, Some safety Classroom time required More math, more practical experience in show setup required. Prep for say NYS CLASS B and on the path to being a touring Show-OP or Outdoor Show Aircraft Spotter. You can skip straight to this if you wish, ie take both tests at once. More involved things like 3 Phase hookup and cable, ANSI z.136, OSHA, and a splitting headache after you take the test.
Reason for the split : At not much above 500 mw, scattered radiation is becoming a hazard and you need more training and math. That is why the IIIB /IV split occurs in the rules. IE Your not doing outdoor shows with 500 mW. Also, from a educational standpoint, its best to progress in stages. After all who wants to set for one huge exam at once?, So a split to two levels makes it easier for those who are not full time laserists. More involved things like 3 Phase hookup and cable .
Many of you hate math, I hate math, by splitting the "tickets" I can reduce the math to tolerable levels.
That should reduce the politics.
