Well this isnt military... but here are a few rules I learned...

1) NEVER refer to your laser as "The yellow beam of death"

2) Never refer to the areas you can shine your laser as a "kill zone" (That got me a talking to...)

3) never refer to co workers as "target practice" for the laser...

4) While announcing "Firing photon torpedoes" may be accurate and cute when opening the laser shutter, it isnt appropriate during a safety review...

5) If co-workers try to wear two sets of laser goggles and as a result are walking into walls you have either:
a) been cavalier about laser safety, and they dont trust you...
b) posted too many first hand accounts of people who have been blinded by lasers on the door to the lab... Including a pair of laser goggles that had been blasted by a 500 watt beam for a second...

(I was guilty of b)
5) Not everyone appreciates a foot long lightning bolt that deafens...
