Does anyone *use* any eye protection (other that not looking at the light, turning off the light etc) -- I mean like protective goggles, etc, when doing simple things like adding/removing patch cables from an SMF patch panel.
There are osha requirements and ansi standards. ANSI Z136.1 - Safe Use of Lasers ANSI Z136.2 - Safe Use of Lasers in Optical Fiber Communication Systems Utilizing Laser Diode and LED Sources
I get that if you *know* the gear you are using has a Class 3 laser on it, you should be careful... but when you are patching it into a building's cable plant and some schmuck is patching the last leg in for you (or has pulled it accidentally, etc).. um, "don't look at it" is our community's BCP?
Actually that's pretty much the requirement for 3r, for 3b and 4 the requirements for eye protection and manual safety systems are much higher. All this high power stuff is rather rare (your cisco ons for example is a class 1 laser product), unless you terminate one end of a submarine system you'll likely never see a class 4 laser in this context. I tend to carry around extra dust protection boots in the tool bag to recover the exposed sc/st plugs that seem to accumulate in panels that people touch a lot, mostly, it protects the ends of the ferrules.
