 |  |  |  | Air-handling UV hazard
< on 8/20/2010 2:53 PM >
|  | | | A few other threads establish that it's largely a bad idea to wander in air ducts. If you really have to, watch for UV germicidal sources. At full power, the high-output lamps cause painful sunburn and cataract damage in about twenty minutes. The output is mostly in the UV-A and UV-B ranges.
You're not likely to stick around that long, but I figured that I'd spread the word. Short doses aren't too bad, but cumulative exposure will damage your vision. I mostly see fluorescent tubes to make the UV. While the cabinet's closed you're probably fine. If your eyes itch, leave. If you see light tubes in a vent, that's iffy. If your socks glow, you're exposed. I don't know of a way to measure exposure to UV before sunburn or that fuzzy eye feeling.

| | | | A note, if you do have to get through an area like this, there are sunglasses specially designed to protect the eyes from both UV-A and UV-B exposures, and sun screen lotions/clothing that are designed for the same reason. As AppleSnail mentioned, it is probably a bad idea in general, but if you have to, and you know ahead of time, plan accordingly and protect your skin and eyes.
P.S. Welding visors/goggles block light from both ranges if you can deal with barely being able to see.

| | | | UV lamps look like clear fluorescent bulbs and they give off invisible UV as well as visible sky blue light.

| | | | glow in the dark paint!
they even make those annoying silly-bands glow in the dark;
it'll start glowing under a blacklight, so I guess it's a much better indicator than your socks. or get some of these http://www.ripnroll.com/knight2.htm

| | | | Indicators are not necessary. They look like this.
Clear fluorescent lamp that glows sky blue. UV is invisible, but the incidental visible light is quite visible.

These are meant for the beach or the pool, but they might work for this purpose too. Maybe? They're relatively inexpensive and lightweight, compared to a meter or something like that, if you're just looking to know if you're exposed or not.

I have to wonder how long it would take the band to cycle around to GTFO against that sort of output, though.

| | | | well if white cotton socks will fluoresce under UV light, tie a strip of a cotton hanky to your wrist.
IF cotton fluoresces under UV light, I'm just going by your glowing socks suggestion

| | | | They are not black lights.... There's no way you'll miss a clear looking fluorescent lamp glowing sky blue.
Blacklights make UVA, germicidal lamps make UVC
