Compact Fluorescent Bulbs have Mercury?!?

Mr. Laser Beam

I know these bulbs have mercury in them. It's one of the reasons I haven't bought any yet. My question is this: Do they have *enough* mercury to be dangerous?

Meaning, if you have one of these CFLs, you drop it on the floor and it breaks, what could happen? Will you get sick? How should you clean it up?
 
Re: Compact Flourescent Bulbs and Mercury

They contain a miniscule amount of mercury - less than 5 milligrams - so do not pose a health hazard. You can read the EPA's guidelines on safe disposal. But if you happen to break one, just open a window to let the area clear, then carefully scoop the fragments into a sealed plastic bag. But really, how often do you break light bulbs? :)

Also, it's best to recycle them once they've burned out, and your area probably has facilities for that. Things like drop boxes at the post office or whatnot - it will depend on what is set up where you live.

Re: Compact Flourescent Bulbs and Mercury

I visited that link. I am very skittish about buying any product where you have to leave the room for 15 minutes if it breaks... :eek: :eek:

I mean, I realize these things save electricity on all that. But I would much rather pay a higher electric bill than die of mercury poisoning!
 
Note: This post is completely biased; almost all of the bulbs in my house are CFLs. ;) The mercury content of CFLs is an understandable concern, and one that others have asked me as well. I asked my father about it before I started buying CFLs (he deals with hazardous waste management for a living, so he knows his stuff). My old man told me that the mercury is definitely not something you should be worried about--if you drop the bulb and break it, you merely carefully clean it up, just like you carefully clean up broken glass from a regular bulb. Mercury is dangerous, but it's not going to magically disappear right when you drop the bulb and spread throughout your house. If dropped, carefully clean up any parts and put them in a plastic bag (damp paper towels and duct tape can be useful to pick up glass particles and errant mercury powder); do not use a vacuum cleaner unless you have to (e.g. you've dropped it on carpet and you've gotten up whatever you can with a brush and tape). Then take the bag to your nearest hazardous waste collection center. Really, no big.

Getting sick is certainly not a concern unless you stick your nose in the pile of mercury and take a nice big whiff. ;) (If you do, I reserve the right to say, "I told you so!") Also, keep in mind that 1.) you only need to change CFLs once ever 5-8 years, in my experience, and 2.) you'll probably be extra careful when you change them b/c you know they have mercury in them. Also, all CFLs that are under 25 watts (and you'll almost never use one over that strength in your house; usually 17 or less is sufficient) have 5 mg or less of mercury (that's roughly 1/6 of an ounce). (See [1], third paragraph.) For further info, the EPA has a nice page on CFL cleanup. (See [2].)

What about the woman in Maine who became concerned about a CFL breaking in her home, then was told by a toxicologist - a toxicologist - that it would take TWO GRAND to clean up the mess?

Look at the part where they determined the various levels of mercury in the home. Specifically, the site where the impact occurred (on the carpet). The Maine Department of Environmental Protection (as said on that link) recommended calling in the professionals to clean up any level that's over about 300 ng/m3. The mercury levels at the impact site were over 1900! :eek:
 
Re: Compact Flourescent Bulbs and Mercury

Even if you took an entire case of bulbs, cracked them open, and took a deep whiff of the fumes you wouldn't come close to dying of mercury poisoning. The disposal procedure is just hyper-cautious. Also, using compact fluorescents actually cuts down on your overall mercury exposure because they reduce mercury emissions from coal-burning power plants.

But that's spread out over the entire Earth. I don't want any mercury anywhere in my home, because that would be much more dangerous immediately. Isn't safeguarding my own personal health, a reasonable goal? I shouldn't have to deliberately expose myself to mercury just to save the planet.

I do care about saving money and protecting the environment. I just think that 1) mercury is much too dangerous a substance to ever allow in my home (I don't have any thermometers or anything like that, either), and 2) there is insufficient infrastructure in place to recycle used CFLs.

I guess you somehow missed the Snopes article saying that the whole story was rather overblown and that the Maine DEP didn't know what it was talking about?

I don't think anyone was recommending you deliberately expose yourself.

If you don't want to use them, don't use them. It's that simple.
 
Re: Compact Flourescent Bulbs and Mercury

But owning CFL bulbs does not expose yourself to mercury. Honestly, can you even remember the last time you broke a light bulb? So I'm wondering why you even asked the question here when you were already aware of, yet ignored, the evidence for their safety.

Re: Compact Flourescent Bulbs and Mercury

I've broken light bulbs before, yes. Both at home and at work (I work in a grocery store). I'm not exactly a klutz, but it has happened to me.

And just to put things in perspective: I *am* a complete and total hypochondriac. :(

Although I have found a site that's reasonably close to here, where they accept things like this for recycling. That's something, anyway.

Who knows how much longer we will still have the option of not using them?

I have also heard of a movement to completely BAN standard incandescent lamps. linky I think that's premature.

I'm aware of efforts to mandate CFL usage by some governments (Australia and Canada, for starters). However, 1.) that isn't happening here, and 2.) focusing on it is merely deflecting the real issue that I raised. The fact of the matter is that you have a choice. Plix and I have both given you our opinions as well as some links. All you have to do is decide what you will do. This isn't a decision that is going to have drastic effects on the rest of your life (at best you'll save a few hundred on energy bills), so try not to over-think it too much. CFLs are not harmful to your health and they can easily be cleaned up (by you, for free). All you have to decide is which bulb you'll pick out the next time you go to the store. :)
 
Re: Compact Flourescent Bulbs and Mercury

I've dropped them before, and had no major health problems that I know of.
 
Re: Compact Flourescent Bulbs and Mercury

At the very least, the packaging for CFLs should mention that they contain mercury (however insignificant the levels are). As I understand it, they do not. There is absolutely no mention of mercury on the label of any CFL sold that I'm aware of (and as I said, I work in a store, so I see this every day).

Would a bit of truth in labeling be too much to ask?

How many years went by before we found out about mercury in immunizations? If they're not going to put a disclaimer on poisons they're putting into infants they're not going to worry about light bulbs. Of course thermometers were a huge threat and they did replace the mercury there.
 
Re: Compact Flourescent Bulbs and Mercury

You kiddies haven't learned yet what wussies you are.... in the 60's we had HANDFULLS of mercury in every science class and regularly got to play with it.

Sure, you were careful and didn't play with it if you had a cut in your hand.... but you didn't run from the room screaming in terror.

Good luck trying to raise any future scientists when you can't even learn to handle chemicals properly!

In the 70's we didn't but in the 60's my dad had a small baby food jar filled with mercury. I can remember him dropping some on the workbench to show me how it broke apart and rolled away like beads. Of course I found where he kept it and pretty soon it was half gone.
 
Re: Compact Flourescent Bulbs and Mercury

I once accidentally ripped out a bank of 4 8-foot floro tubes with a forklift. The tubes were directly overhead and I was showered in glass and crap. Though I wouldn't want to repeat the experience I didn't get sick from that, and I can't see how a CFL popping open would be any real hazard.
The other cool thing about CFL's is they have a full spectrum, a much more natural light than incandescents.

You know, I was just about to post the same thing. I can't believe that people freak out over simple exposure to it (i.e. being in the same room). It's not radioactive or something for God's sake.

And it is a lot of fun to play with. :)
 
Re: Compact Flourescent Bulbs and Mercury

The one drawback to mercury is that exposure is cumulative. Once it's in you, it pretty much dosen't leave.

However the amounts in a CF are quite trivial.
