Officials are downplaying the risk of radiation from Japan reaching the U.S. so, as a replacement concern, here are the EPA instructions for cleaning up a broken CFL (Curley Federal Lightbulb).

Before Cleanup

• Have people and pets leave the room, and avoid the breakage area on the way out.
• Open a window or door to the outdoors and leave the room for 5-10 minutes.
• Shut off the central forced-air heating/air conditioning (H&AC) system, if you have one.
• Collect materials you will need to clean up the broken bulb:
  • Stiff paper or cardboard
  • Sticky tape (e.g., duct tape)
  • Damp paper towels or disposable wet wipes (for hard surfaces)
  • Glass jar with a metal lid (such as a canning jar) or a sealable plastic bag(s)

Cleanup Steps for Hard Surfaces

• Carefully scoop up glass fragments and powder using stiff paper or cardboard and place debris and paper/cardboard in a glass jar with a metal lid. If a glass jar is not available, use a sealable plastic bag. (NOTE: Since a plastic bag will not prevent the mercury vapor from escaping, remove the plastic bag(s) from the home after cleanup.)
• Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder. Place the used tape in the glass jar or plastic bag.
• Wipe the area clean with damp paper towels or disposable wet wipes. Place the towels in the glass jar or plastic bag.
• Vacuuming of hard surfaces during cleanup is not recommended unless broken glass remains after all other cleanup steps have been taken. [NOTE: It is possible that vacuuming could spread mercury-containing powder or mercury vapor, although available information on this problem is limited.] If vacuuming is needed to ensure removal of all broken glass, keep the following tips in mind:
  • Keep a window or door to the outdoors open;
  • Vacuum the area where the bulb was broken using the vacuum hose, if available; and
  • Remove the vacuum bag (or empty and wipe the canister) and seal the bag/vacuum debris, and any materials used to clean the vacuum, in a plastic bag.
• Promptly place all bulb debris and cleanup materials, including vacuum cleaner bags, outdoors in a trash container or protected area until materials can be disposed of properly.
  • Check with your local or state government about disposal requirements in your area. Some states and communities require fluorescent bulbs (broken or unbroken) be taken to a local recycling center.
• Wash your hands with soap and water after disposing of the jars or plastic bags containing bulb debris and cleanup materials.
• Continue to air out the room where the bulb was broken and leave the H&AC system shut off, as practical, for several hours.

Cleanup Steps for Carpeting or Rugs

• Carefully scoop up glass fragments and powder using stiff paper or cardboard and place debris and paper/cardboard in a glass jar with a metal lid. If a glass jar is not available, use a sealable plastic bag. (NOTE: Since a plastic bag will not prevent the mercury vapor from escaping, remove the plastic bag(s) from the home after cleanup.)
• Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder. Place the used tape in the glass jar or plastic bag.
