Compact Fluorescent Light (CFL) Safety Information

Compact Fluorescent Light Bulb
Did you know?

ENERGY STAR® qualified compact fluorescent light bulbs use up to 75 percent less energy than standard incandescent bulbs. One CFL can save up to $30 in energy costs over its lifetime. CFLs last up to ten times longer than standard incandescent bulbs. CFLs contain a small amount of mercury encased in the base of the bulb, but pose no harm to consumers because they do not emit mercury when they are intact, in use, properly stored or handled.

How should I clean up a broken CFL?

Because CFLs contain a small amount of mercury, the Environmental Protection Agency recommends the following clean-up and disposal guidelines:

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 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 pieces 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, 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 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 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.
