I accidentally dropped a CFL and the glass broke when it hit the floor, should I be worried?

As the use of CFLs continues to rise, many people are wondering what they should do after a compact fluorescent lamp breaks. There’s a lot of misinformation circulating about mercury and the dangers of being exposed to it, so it’s important to understand the facts. While CFLs do in fact contain small quantities of mercury, breaking one is nothing to get worried about. In fact, the solution is a simple clean-up procedure! You should feel good about your choice to use CFLs in your home, not only because they save money and energy but because they’re good for the environment.

From Energy Star: “CFLs contain a very small amount of mercury sealed within the glass tubing – an average of 4 milligrams – about the amount that would cover the tip of a ballpoint pen. By comparison, older thermometers contain about 500 milligrams of mercury – an amount equal to the mercury in 125 CFLs. Mercury is an essential part of CFLs; it allows the bulb to be an efficient light source. No mercury is released when the bulbs are intact (not broken) or in use.“

From NEMA: “Breaking one fever thermometer is unlikely to threaten the health of the consumer. Proper cleanup of spilled mercury and adequate ventilation can minimize the risks even further.” Keeping in mind that thermometer’s contain much more mercury than a CFL, they go on to say “…lamp breakage would appear to cause virtually no risk of harm.” For more information, click here.

For some perspective, many of the fish we eat contain quantities of mercury much larger then what is used in a single CFL bulb. What this means is that by consuming healthy and natural foods, you could consume more mercury in a year than you will be exposed to by one broken CFL lamp.

How should I clean up a broken compact fluorescent light bulb (CFL)? (from Energy Star)

1. Before Clean-up: Ventilate the Room

• Have people and pets leave the room, and don’t let anyone walk through the breakage area on their way out.
• Open a window and leave the room for 15 minutes or more.
• Shut off the central forced-air heating/air conditioning system, if you have one.

2. Clean-Up Steps for Hard Surfaces

• Carefully scoop up glass fragments and powder using stiff paper or cardboard and place them in a glass jar with metal lid (such as a canning jar) or in a sealed plastic bag.
• Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder.
• Wipe the area clean with damp paper towels or disposable wet wipes and place them in the glass jar or plastic bag.
• Do not use a vacuum or broom to clean up the broken bulb on hard surfaces.

3. Clean-up Steps for Carpeting or Rug:

• Carefully pick up glass fragments and place them in a glass jar with metal lid (such as a canning jar) or in a sealed plastic bag.
• Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder.
• 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 a sealed plastic bag.

4. Clean-up Steps for Clothing, Bedding, etc.:

• If clothing or bedding materials come in direct contact with broken glass or mercury-containing powder from inside the bulb that may stick to the fabric, the clothing or bedding should be discarded.  Do not wash such clothing or bedding because mercury fragments in the clothing may contaminate the machine and/or pollute sewage.
• You can, however, wash clothing or other materials that have been exposed to the mercury vapor from a broken CFL, such as the clothing you happened to be wearing when you cleaned up the broken CFL, as long as that clothing has not come into direct contact with the materials from the broken bulb.
• If shoes come into direct contact with broken glass or mercury-containing powder from the bulb, wipe them off with damp paper towels or disposable wet wipes.  Place the towels or wipes in a glass jar or plastic bag for disposal.

5. Disposal of Clean-up Materials

• Immediately place all cleanup materials outdoors in a trash container or protected area for the next normal trash pickup.
• Wash your hands after disposing of the jars or plastic bags containing clean-up materials.
• Check with your local or state government about disposal requirements in your specific area.  Some states prohibit such trash disposal and require that broken and unbroken mercury-containing bulbs be taken to a local recycling center.

6. Future Cleaning of Carpeting or Rug: Ventilate the Room During and After Vacuuming

• The next several times you vacuum, shut off the central forced-air heating/air conditioning system and open a window prior to vacuuming.
• Keep the central heating/air conditioning system shut off and the window open for at least 15 minutes after vacuuming is completed.
