Everything good is bad.  Is everything bad, good?  Compact flourescent bulbs are dangerous.  If you break one, don't panic.  Just follow these 11 simple steps:

1. Open a window and leave the room for 15 minutes or more.
2. Shut off the central forced-air heating/air conditioning system, if you have one.
3. 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.
4. Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder.
5. Wipe the area clean with damp paper towels or disposable wet wipes and place them in the glass jar or plastic bag.
6. Do not use a vacuum or broom to clean up the broken bulb on hard surfaces.
7. Immediately place all cleanup materials outside the building in a trash container or outdoor protected area for the next normal trash.
8. Wash your hands after disposing of the jars or plastic bags containing cleanup materials.
9. 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 lamps be taken to a recycling center.
10. For at least the next few times you vacuum, shut off the central forced-air heating/air conditioning system and open a window prior to vacuuming.
11. Keep the central heating/air conditioning system shut off and the window open for at least 15 minutes after vacuuming is completed.

Thanks, Hot Air.  I'm rocking in the corner.
