Broken Fluorescent Lights

If you accidentally break a light, follow the steps below to make sure that the bulbs are cleaned up safely. Keep in mind that in California fluorescent bulbs and tubes are prohibited from trash disposal. You’ll need to take the broken bulbs to one of the collection centers listed on our Fluorescent Tube or Compact Fluorescent Light (CFL) pages.

Before Clean-Up: Air Out the Room

  • Evacuate all people and pets and make sure no one walks through the breakage area on the way out
  • Open all windows and leave the room for at least 15 minutes
  • Shut off the central forced-air heating and air conditioning systems

Hard Surface Clean-Up

  • Wearing gloves, carefully scoop up glass pieces and powder using stiff paper or cardboard and place them in a glass jar with a 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 the towels in the glass jar or plastic bag
  • Do not use a vacuum or broom to clean up the broken bulb on hard surfaces

Carpet or Rug Clean-Up

  • Wearing gloves, carefully scoop up glass pieces and powder using stiff paper or cardboard and place them in a glass jar with a 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 and vacuum debris in a sealed plastic bag

Clothing, Bedding or other Soft Material Clean Up

  • If clothing or bedding materials come in direct contact with the broken glass or mercury-containing powder from the inside of the bulb, the clothing or bedding should be thrown away because the mercury and glass may stick to the fabric. 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 Compact Fluorescent Light (CFL), such as the clothing you are wearing when you cleaned up the broken CFL. As long as that clothing has not come in into direct contact with the materials from the broken bulb, you should be fine.
  • If shoes come into direct contact with powder from the bulb, wipe them off with a damp paper towel or disposable wet wipes. Place the towels or wipes in a glass jar or plastic bag for disposal.

Disposing of Clean-Up Materials

  • Immediately place all clean-up materials outdoors in a protected area until you’re ready to bring them to a collection center
  • When ready, take these materials to one of the hazardous waste facilities listed on our Fluorescent Tube or Compact Fluorescent Light (CFL) pages

Future Cleaning of a Carpet or Rug

  • The next several times you vacuum, turn off any central forced-air heating and air conditioning systems and open a window before vacuuming
  • Keep the central heating and air conditioning system turned off and the window open for at least 15 minutes after you are done vacuuming

More Information

People use other products that contain mercury, not just fluorescent lights. In the event that any of these products break, certain steps need to be taken for safe clean-up and disposal. Check out the US Environmental Protection Agency’s website for more information on storing, transporting, and disposing of mercury.
