How Do Incandescent Lights Result in More Mercury Pollution Than Fluorescents?

In addition to carefully recycling products that contain mercury, we can reduce mercury pollution by reducing our energy consumption. Because mercury is a byproduct of burning coal, coal-fired power plants are one of the largest sources of mercury pollution. Because incandescent bulbs use several times more electricity over their lifetimes, they require far more power generation and, ultimately, result in more mercury emission than fluorescents. With the coming “maximal achievable technology” clean air standards, it is fully expected that mercury emissions will have to be severely reduced in order to stop this proliferation. Fluorescent lights are four to six times more efficient than incandescent lamps, significantly reducing the power demand from local utilities. The reduced demand for electricity in turn reduces both greenhouse gas and mercury emissions.

Lighting the Workplace with Fluorescent Bulbs

Many businesses strive to keep management expenses low, ensure energy efficiency and provide a safe work environment for employees. When it comes to selecting lighting, all of these aspects must be factored in. Fluorescent lamps have long been the best lighting option for small to large businesses, due to their significant energy savings—providing four to six times higher efficiency than incandescent lights—and long working life. However, these lamps contain hazardous mercury and, from installation to disposal, they must be carefully handled, stored and transported.

While the amount of mercury used in an individual fluorescent bulb has decreased over the past years, one broken four-foot fluorescent lamp in a small room or vehicle can release enough mercury vapor to exceed the OSHA mercury exposure eight-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. Recent legislation has begun to address the issue of safe packaging for fluorescent lamps and other mercury-containing products, and facility managers must work to not only comply with these regulations, but also ensure the safety of all personnel in addition to protecting the environment.
