| | | | 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. http://www.tuopeek.com/images/uvc2.JPG

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. http://www.uvsunsense.com/uvss/ 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
