The bottom line on CFLs and mercury

Don't let reports of mercury in CFLs discourage you from using energy-efficient light bulbs. While it's true that the bulbs do contain tiny amounts of mercury, it's also important to remember that problems only arise when bulbs break at home (and elsewhere) or in a landfill.

Here's how to responsibly and effectively deal with both issues.

Disposal

Recycling is a cinch now that all Home Depot and Ikea stores offer free take-back programs. If you don't live near one of these retailers, search Earth 911's database for nearby recyclers.  

Clean Up

No need to panic if a bulb breaks. Just follow these strategies from the Environmental Protection Agency and a study conducted by Maine's Department of Environmental Protection.    

  • Air out the room. Open the windows and have everyone leave for 15 minutes. Be careful not to walk through the breakage on your way out. Close the door behind you. Turn off central air-conditioning/heating system if you have one.
  • Carefully gather glass pieces and powder with cardboard or other stiff paper such as index or playing cards. Use duct tape, or other sticky tape, to pick up remaining small glass and powder. Place everything in a glass jar with a metal lid or a sealed plastic bag. You might want to use disposable rubber gloves if you have them.
  • If you're cleaning up a floor or other hard surface, use damp paper towels or disposable wet wipes to wipe the area. Never vacuum or sweep with a broom because you run the risk of increasing mercury exposure.
  • The federal EPA says, if you're dealing with a carpet or rug and have to vacuum the area where the bulb broke, you should remove the bag when you're done and place it in a sealed plastic bag. Maine's EPA suggests throwing out area rugs or removing parts of carpet as an added precaution. If you keep rugs, then good ventilation is essential the next several times you vacuum. Open windows and turn off you're your central air-conditioning/heating system before and after vacuuming.
  • Throw away any clothing or bedding that came into direct contact with broken glass or powder. Washing may contaminate your machine and pollute sewage. You can wash clothing that was in the room, but not in direct contact with the broken bulb. Wipe down shoes with damp towels or wet wipes and put them in a sealed jar or bag.   
  • Immediately place all your clean-up materials outside. Wash your hands and face thoroughly. Check with your local government to see how to dispose of broken bulbs. In some cases you can dispose of it with your normal trash pick-up, but recycling is preferable.

    armellegloaguen, thank you for the intelligent comment. I have the same--a baggie for old batteries, a baggie for old bulbs, a baggie with two ancient cell phones I still have to recycle, too, but I will eventally. It's not THAT hard, people, just do it with common sense and a little grain of organization. I do agree also that while you have to be careful and use common sense, it really isn't going to KILL you if you are exposed to this a couple times in your life. Really.

    At one place I worked we would change the florescent tubes and what would we do with all the old ones (bunches of them) We would throw them in the dumpster from the loading dock just to watch them explode. That was 15 years ago, but I'm pretty sure the wind was blowing our way, and I still am alive! Can you believe it? Didn't all of our parents play with mercury in school? I read somewhere that the amount of mercury released into the air from coal to power a regular light bulb quadruples or more the amount contained in a CFL. I actually broke 2 and my wife broke one the other day by accident. Oops, I didn't replace my carpet.

    The amount of mercury released by a CFL bulb is far less than the amount of mercury released by burning coal to produce the electricity used during the life of an regular light bulb of equivalent luminosity. CFLs are not perfect, but they are a step in the right direction. LED lights are the future replacement for CFLs. They last much longer and contain no mercury and use miniscule amounts of power. Once they become cheaper and brighter they will be the bulb of choice.

    The author has a bad case of ill-informed chicken little syndrome. Probably is worried about cancer from cell phones, and the effects of electromagnetic waves from home appliances. Such attitudes are tolerable -- its a free country, after all -- but their editors should have a look at the technical validity of their writings. Cut out part of the carpet? Really??

    This artical is where all the consperecy nuts and germa-phodes get all their ammunition. Murcury IS bad for you, but the tiny amounts are of no concern to the general public. I mean, come on, we readily EAT chemicals that KILL insects on our foods and are afraid of a light bulb... get a grip!!!!

    These bulbs are NOT green PERIOD! Note how many times the article states "throw away" & what happens to all the tainted things (not to mention a simple burned out bulb) that get thrown out? They go to the landfill to create yet another environmental hazard! Why did we bother to eliminate mercury from batteries years ago if were going to replace it with that from so called "green" bulbs? I also wonder how much of an environmental problem is being created in China as close to if not 100% of these bulbs are made there? They dont have a very good record when it comes to the environment.

    Most people are just morons. If you could save money and the enviroment by switching to these lightbulbs you should. If all it takes is returning a lightbulb every coulple of years to Home Depot you should. Most of you conservative rednecks are there 5 times a week as it is. It's like the question;Would you give up your remote control to stop global warming?. Most idots reply,NO,global warming doesn't exist.

    Utterly absurd-glass shards will quickly and easily cut through the environmentally unsound, petroleum product of a plastic bag. The bag does not address the issue-it only becomes extra trash-another piece of plastic carelessly wasted and discarded in yet another landfill. And the air issue hasn't been dealt with at all. Wake up people!!

    The people who thought up this idea using these bulbs and letting the puplic use them are determind to only make money not help the general puplic with cost of energy or conservation..What happens when your three year old knocks over the lamp in a room in the back of the house where he/she is playing and it is minutes before he/she comes tells you what happened(if you are told at all)? Think about that for a moment..your child!

    All of this effort to be "green"? Too labor intensive for my tastes...What am I missing here? Can't afford to purchase them in the first place!!

    I agree that they should not be sold to the general public and I like the old incandescent s better however we have had one light with the CFL in it an kept it on 24/7, lasted six plus years.

    Yes such "easy and simple" steps! Talking about contamination, throwing away clothes, rugs etc. And what if it breaks on carpet? Are you supposed to cut off a piece of the carpet or something and have a big hole in the middle of the room? The "easy and simple" steps are ridiculous! I never want to buy one of these bulbs again! It's crazy and dangerous to have such a "tiny" substance which can cause so many problems. Bah!
