Compact Fluorescent bulb broke on my desk... how do I clean up properly?

Question

I heard these bulbs contain mercury... but how much? It was like two weeks ago when it happened... the glass is gone obviously but should I scrub my desk down to be safe?

Answer 1

How should I clean up a broken fluorescent bulb?
The following steps can be performed by the general public:
1.
Open a window and leave the room for 15 minutes or more.
2.
Carefully scoop up the fragments and powder with stiff paper or cardboard and place them in a sealed plastic bag.
ƒ
Use disposable rubber gloves, if available (i.e., do not use bare hands). Wipe the area clean with damp paper towels or disposable wet wipes and place them in the plastic bag.
ƒ
Do not use a vacuum or broom to clean up the broken bulb on hard surfaces.
3.
Place all cleanup materials in a second sealed plastic bag.
ƒ
Place the first bag in a second sealed plastic bag and put it in the outdoor trash container or in another outdoor protected area for the next normal trash disposal.
o Note: some states prohibit such trash disposal and require that broken and unbroken lamps be taken to a local recycling center.
ƒ
Wash your hands after disposing of the bag.
4.
If a fluorescent bulb breaks on a rug or carpet:
ƒ
First, remove all materials you can without using a vacuum cleaner, following the steps above. Sticky tape (such as duct tape) can be used to pick up small pieces and powder.
ƒ
If vacuuming is needed after all visible materials are removed, vacuum the area where the bulb was broken, remove the vacuum bag (or empty and wipe the canister) and put the bag or vacuum debris in two sealed plastic bags in the outdoor trash or protected outdoor location for normal disposal.
What is mercury?
Mercury is an element (Hg on the periodic table) found naturally in the environment. Mercury emissions in the air can come from both natural and man-made sources. Coal-fired power plants are the largest man-made source because mercury that naturally exists in coal is released into the air when coal is burned to make electricity. Coal-fired power generation accounts for roughly 40 percent of the mercury emissions in the U.S.
EPA is implementing policies to reduce airborne mercury emissions. Under regulations EPA issued in 2005, mercury emissions from coal-fired power plants will drop by nearly 70 percent by 2018.
The use of CFLs reduces power demand, which helps reduce mercury emissions from power plants.

Frequently Asked Questions
Information on Compact Fluorescent Light Bulbs (CFLs) and Mercury
August 2007
Why should people use CFLs?
Switching from traditional light bulbs to CFLs is an effective, accessible change every American can make right now to reduce energy use at home and prevent greenhouse gas emissions that contribute to global climate change. Lighting accounts for close to 20 percent of the average home’s electric bill. ENERGY STAR qualified CFLs use up to 75 percent less energy than incandescent light bulbs, last up to 10 times longer, cost little up front, and provide a quick return on investment.
If every home in America replaced just one incandescent light bulb with an ENERGY STAR qualified CFL, in one year it would save enough energy to light more than 3 million homes and prevent greenhouse gas emissions equivalent to those of more than 800,000 cars.
Do CFLs contain mercury?
CFLs contain a very small amount of mercury sealed within the glass tubing – an average of 5 milligrams – about the amount that would cover the tip of a ball-point pen. By comparison, older thermometers contain about 500 milligrams of mercury. It would take 100 CFLs to equal that amount.
Mercury currently is an essential component of CFLs and is what allows the bulb to be an efficient light source. No mercury is released when the bulbs are intact or in use. Many manufacturers have taken significant steps to reduce mercury used in their fluorescent lighting products. In fact, the average amount of mercury in a CFL is anticipated to drop by the end of 2007 thanks to technology advances and a commitment from members of the National Electrical Manufacturers Association.
What precautions should I take when using CFLs in my home?
CFLs are made of glass and can break if dropped or roughly handled. Be careful when removing the bulb from its packaging, installing it, or replacing it. Always screw and unscrew the lamp by its base (not the glass), and never forcefully twist the CFL into a light socket. If a CFL breaks in your home, follow the clean-up recommendations below. Used CFLs should be disposed of properly (see below).
What should I do with a CFL when it burns out?
EPA recommends that consumers take advantage of available local recycling options for compact fluorescent light bulbs. EPA is working with CFL manufacturers and major U.S. retailers to expand recycling and disposal options. Consumers can contact their local municipal solid waste agency directly, or go to epa.gov/bulbrecycling or earth911.org to identify local recycling options.
If your state permits you to put used or broken CFLs in the garbage, seal the bulb in two plastic bags and put it into the outside trash, or other protected outside location, for the next normal trash collection. CFLs should not be disposed of in an incinerator.
ENERGY STAR qualified CFLs have a warranty. If the bulb has failed within the warranty period, return it to your retailer.
How should

Answer 2

Yes.
The bulb did indeed contain mercury vapor, but that's long gone
and the amount was small in any event.
This hysteria about small amounts of mercury
is a bit amusing.
I'd worry more about the rare earth phosphors.
Some of those might be far more toxic than the mercury ever could be.
I'd at least wipe down the desk with a damp cloth, and discard the cloth.

Answer 3

Sweep it up into garbage sack with a hand broom then wipe down the desk with some pappertowels and rubbing alcohol. Wear rubber gloves while doing that incase there is any broken glass still on the desk. I would vacum up the carpet too if you suspect any class may have fallen off your desk.

Answer 4

This replaced into revealed 7 years in the previous so your approximately 21-22 now. The rules have of path replaced because of the certainty then and that i'm turning 15 in some months and a few of my buddies have jobs yet i do no longer understand techniques i flow approximately getting a activity as we communicate. i ought to extremely appreciate if somebody ought to grant an up subsequently some distance checklist of jobs and the thank you to get a activity create a CV and so on. thank you forward to everybody whose type adequate to help :)

Answer 5

mercury? Not! They would not recommend the bulbs as they would be a hazard when they are tossed in the landfill.
