OT mercury
Locked
 
|
metallic mercury rolled around in your hand is not absorbed through the skin. I don't know, not about to try it, but I think it would just come out the other end if you ate it.
You know, "they" banned lead from paints. But the binder for latex paints is mercury. They have banned mercurial thermometers, course that's metallic mercury and won't be absorbed, BUT, there is mercury in flu shots, children's vaccines, latex paint, and amalgam tooth fillings. go figure! Where is mercury found? In rocks. (Specifically bauxite). so technically, it is a land fill to begin with. 72, Fred - kt5x _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

My Lady and I are hosts/docents at a lighthouse on the Oregon
coast and I've "been to sea" for a few years. This has created an awareness of lighthouse-related things and one of these is the legend that keepers sometimes went insane "from the isolation and loneliness of lighthouse duty". It's now generally attributed to handling the mercury used ... in large quantities ... as a lubricant in some light rotation mechanisms. The same applies to the "mad as a hatter" phrase. They used mercury in the hat manufacturing process. WAY off topic ... sorry. 73!

Not insane maybe, but 30 years tending a lighthouse, the light
and intermittent fog horn never bothered the old man keeper, until early one morning the fog horn failed to sound off... the old man woke up with a start and wondered "What was that?" de Joe, aa4nn > awareness of lighthouse-related things and one of these is the > legend that keepers sometimes went insane "from the isolation > and loneliness of lighthouse duty".

Fred, et.al.
I'll suggest this: <http://en.wikipedia.org/wiki/Mercury_poisoning> for a starter discusion of the ill effects of mercury upon. -- 73 Rod, Ai7NN On 4/15/07, Trail Fox <[hidden email]> wrote: > metallic mercury rolled around in your hand is not absorbed through the skin.

A few records need to be set straight here:

The Material Safety Data Sheet (MSDS) on mercury says "Skin absorption is a significant route of potential over-exposure to Mercury..." It's not the principle route of entry. Inhalation of mercury vapour, which is given off at room temperature, is the principle means. > I don't know, not about to try it, but I > think it would just come out the other end if you > ate it. Oral ingestion (according to the MSDS) is said not to be a significant route of occupational over-exposure, but if ingested it does cause severe gastro-intestinal damage as well as kidney damage. Glad you're not going to try eating any. > Where is mercury found? In rocks. (Specifically > bauxite). Bauxite is the principle ore of Aluminum. If there's any Mercury in Bauxite it's there in trace amounts as an impurity. Cinnabar is the principle ore of Mercury. Cinnabar's a mineral, Mercury Sulphide. 73 - Ken _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Biggest problem with spilled mercury is that it is nearly impossible to clean up, and will continue to evaporate and expose people to its poisonous vapors. > They have banned mercurial thermometers, course that's metallic > mercury and won't be absorbed, BUT, there is mercury in flu shots, > children's vaccines, latex paint, and amalgam tooth fillings. Mercury in these uses isn't likely to evaporate and be inhaled.

There was an article in the paper about CFL lamps ( those twisty energy
saving bulbs ) and they are supposedly dangerous. Drop one and it's, open the window and shut the doors on the room, call the EPA! http://www.epa.gov/mercury/spills/ I have the things all over the house and didn't even realize the danger.

Best learn how to deocontaminate the place before it happens...and don't call any gubmint agencies if you break one. THey will simply force you to engage the services of the certified folks who come in moon suits and not only remove the mercury, but also a significant part of your income. Wonder when the anti-CFL lobby will pass a law making the manufacturers of those devices liable for the damage?

I seldom break any bulb, in fact I can't remember the last time I did. I
can't see why I would break a CFL any more frequently. My main objection to the several I have installed in my house is that they take several minutes to come up to full output. Not terribly useful in a passageway. I've got several installed in the basement in place of the 100W bulbs I was using there to get sufficient light. Typical weenie builder only put one lighting circuit in the basement and also sourced the sump pump from it. Needless to say the breaker pops at the most inconvenient time leaving me stumbling around in the pitchblackness. The improved efficiency of the CFLs now gives me the needed light without rewiring the basement and without popping the breaker. Of course the same building codes that allow this sort of corner-cutting wiring also require a licensed electrician to do more than change a lightbulb in Baltimore county.

Different brands work better then others.
Some can pulse, some have to warm up, some don't work in the cold. The ones that home depot sells seem good, you can get spotlights, 3 way bulbs, little versions, yellow bug lamps, etc. Save your receipts, some blow out in short order, but if they work for 10 minutes, they usually last years. The last few years I have gone big-time into LED xmass lights. You can run thousands of those things all December for about 45 cents!

I just looked at them recently and noticed that some come with mercury and
some don't. It seems the more expensive lights do not have mercury in them. It just seems like anything that is healthy for you always costs more.

No need to worry much longer about "breaking" the
small flourescent bulbs, so popular now in Australia and WMart - there are about to be eclipsed by the new LOW WATTAGE LED BULBS. The LED technolgoy is already in use on sailboat mastheads, 18-wheeler tail\lights, and most updated red/green/yellow traffic lights. For home use - something like 4 watts, last forever.

Fred,
The LED traffic lights in FL must work better than the ones in my town. The LEDs appear to burn out in patches. Looks like a leaf that a bug has been dining on. On the positive side, the manufacturers will certainly get their act together in time. 72, Jim - W4BQP K2 #2268 ARES EC, Spartanburg Co., SC Fred (FL) wrote: > No need to worry much longer about "breaking" the > small flourescent bulbs, so popular now in Australia > and WMart - there are about to be eclipsed by the > new LOW WATTAGE LED BULBS.
