Light Bulbs (Fluorescent / CFL) Illegal in Garbage & Drains Hazardous Waste Never Throw in the Trash Fluorescent light bulbs contain mercury, which is a hazard for your health and the environment. Never throw them away. Store them outside in a sealed container, and dispose of them as Household Hazardous Waste. Air Out Room if Bulb Breaks Broken CFL bulbs can release mercury vapor. If one breaks, clear people and pets out of the room, and then air it out for five to ten minutes. To stop the vapor from spreading, also shut off the heat, ventilation and air-conditioning. Avoid Vacuuming if Possible Don’t use a vacuum to clean up because this can spread the mercury powder from a broken CFL bulb. Instead, sweep up broken pieces with cardboard or paper. If there are any leftover shards of glass, use a piece of tape to pick them up.
