  1. Like all mercury-containing fluorescent lights, CFLs should be properly stored, transported and recycled to prevent these fragile bulbs from breaking and emitting hazardous mercury vapor. However, as this article states, if bulbs are broken they need to be sufficiently cleaned up. Furthermore, they cannot be thrown away in the trash, but should be taken to a recycling center or disposed of by using a proven recycling box. As CFLs and fluorescent bulbs are steadily replacing incandescents, it is important for consumers to understand the importance of properly recycling them. A recent study conducted by the University of Minnesota tested the effectiveness of various packages in containing mercury vapor emitted from broken fluorescent lamps. The study found that many packages do not sufficiently contain mercury vapor, such as single-layer cardboard boxes (representing the original manufacturer’s box or container) as well as single layer boxes with a sealed plastic bag. Just one configuration—consisting of a zip-closure plastic-foil laminate bag layered between two cardboard boxes—minimized exposure levels below acceptable occupational limits, as defined by state and federal regulations and guidelines.
