What to Do if a Fluorescent Light Bulb Breaks
Compact fluorescent lights (CFLs) are lighting more homes than ever before, and EPA is encouraging Americans to use and recycle them safely. Carefully recycling CFLs prevents the release of mercury into the environment and allows for the reuse of glass, metals and other materials that make up fluorescent lights.
Fluorescent light bulbs contain a very small amount of mercury sealed within the glass tubing. EPA recommends the following clean-up and disposal below. Please also read the information on this page about what never to do with a mercury spill.
Before Clean-up: Air Out 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.
Clean-Up Steps for Hard Surfaces
* Carefully scoop up glass pieces 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. Place towels in the glass jar or plastic bag.
* Do not use a vacuum or broom to clean up the broken bulb on hard surfaces.
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.
Clean-up Steps for Clothing, Bedding and Other Soft Materials
* 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 thrown away. 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 are 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.
Disposal of Clean-up Materials
* Immediately place all clean-up 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 do not allow such trash disposal. Instead, they require that broken and unbroken mercury-containing bulbs be taken to a local recycling center.
Future Cleaning of Carpeting or Rug: Air Out 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 before vacuuming.
* Keep the central heating/air conditioning system shut off and the window open for at least 15 minutes after vacuuming is completed.
Cleaning up a broken CFL by vacuuming up the smaller debris particles in an un-vented room can elevate mercury concentrations over the MAAG in the room and it can linger at these levels for hours. Vacuuming tends to mix the air within the room such that the one foot and five foot heights are similar immediately after vacuuming. A vacuum can become contaminated by mercury such that it cannot be easily decontaminated. Vacuuming a carpet where a lamp has broken and been visibly cleaned up, even weeks after the cleanup, can elevate the mercury readings over the MAAG in an un-vented room.
The decision on whether or not to remove carpet where there was a broken lamp may depend on a number of factors including the location of the carpet (e.g. where a child plays or where the carpet is frequently agitated), the occupants of the household, or possibly the type of lamp broken.
Finally, it is unclear what the exact health risks are from exposure to low levels of elemental mercury, especially for sensitive populations, so advising for the careful handling and thoughtful placement of CFLs may be important.
