Light Bulbs (Halogen) Hazardous Waste Through the IWMA’s SLO Take Back Program, every retailer that sells Halogen lightbulbs in San Luis Obispo County must take those items back from the public for FREE. To be disposed of through this program, lightbulbs may not be broken. The SLO Take Back Program is funded by a grant from the California Integrated Waste Management Board. 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. Did You Know? Which Bulbs Are More Energy Efficient Than Incandescent Lamps?
