Fluorescent Lamp and CFL Disposal

Disposing of mercury-containing products, including fluorescent lamps and CFLs, is an important issue. It is important for consumers to realize that CFLs and fluorescent bulbs require special handling and disposal. 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. 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.

However, taking them to a recycling center may not always be the most efficient solution. Consumers can use a recycling box to ship bulbs instead. If consumers choose this option, it is important to select a packaging configuration that effectively contains mercury vapor. 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.

Why Should You Make the Switch?

Fluorescent lamps and CFLs are four to six times more efficient than their incandescent counterparts and emit about the same amount of visible light, all while offering longer working life and saving significant energy costs. Further, energy-efficient lighting is one of the lowest-cost ways for the nation to reduce electricity use and greenhouse gases. Although incandescent light bulbs may seem like the cheaper option at the counter, consumers will actually save money on CFLs in the long run. While a CFL may cost about $2.00 per bulb, compared to about $0.50 cents for an incandescent bulb, a CFL lasts an estimated 8 to 15 times as long as an incandescent.

However, CFLs and fluorescent lamps also contain hazardous mercury vapor, which is emitted when these fragile bulbs break. If not carefully handled and disposed of, mercury vapor can cause significant health and safety issues, as well as environmental concerns. It is important to always recycle used or broken bulbs.

Mercury and Fluorescent Lamps

While the amount of mercury used in an individual fluorescent bulb has decreased over the past years, one broken 4-foot fluorescent lamp in a small room or vehicle can release enough mercury vapor to exceed the OSHA mercury exposure 8-hour limit—posing a significant occupational health risk. Plus, mercury vapor can be emitted for weeks after a single bulb is broken.

In their lifetime, fragile fluorescent lamps are handled by manufacturers, transporters, distributors, retailers, consumers and installers, as well as recycling or waste handlers. Although the lamps could break anywhere down this line and expose workers and the environment to hazardous mercury vapors, there are no universally enforced packaging standards designed to protect these people. Currently, only one package design, which includes a vapor resistant and zip seal bag, has proven effective in containing mercury vapor.

Mercury Permissible Exposure Limit: How Much is Too Much?

The Federal Occupational Health and Safety Administration (OSHA) set a mercury permissible exposure limit (PEL) of 0.1 mg/m3 (8-hr time-weighted average [TWA]).1 Some state OSHA programs regulate a stricter mercury vapor limit of 0.05 mg/m3 (8-hr TWA). Additionally, the American Conference of Governmental Industrial Hygienists (ACGIH) recommends an a guideline of 0.025 mg/m3; this is the same value regulated by California OSHA.2

One broken 48-inch fluorescent lamp in a small room or vehicle can release enough mercury vapor to exceed the Federal OSHA PEL. Mercury vapor concentrations could exceed occupational exposure levels when working with or near broken bulbs, especially when multiple bulbs are stored or shipped in bulk to recycling facilities. Based on measurements of mercury vapor from single broken fluorescent bulbs, there is a need for additional research to quantify emissions from various types of packaging. The results indicate that emissions from packages not designed to contain mercury vapor represent a real health and safety concern to those involved in its storage, transport and disposal, as well as a legal hazard for any businesses that do not adhere to these stipulations.
