Light Bulbs (Halogen) Put in Garbage Air Out Room if Bulb Breaks Broken halogen 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. Don't Mix with Glass Recyclables The materials used to make halogen bulbs are non-toxic, so it’s okay to throw these bulbs in the trash. Although they are made of glass, don’t recycle them with glass. Broken glass can injure sanitation workers. Wrap Before Disposing Light bulbs are fragile and can break in the trash. Try wrapping them in newspaper and taping everything in place before disposing of the bulb. This extra step can prevent the bulb from breaking in the trash. Did You Know?
