Where Does Mercury Vapor Find Us?


Today, mercury continues to be used in many products, primarily in fluorescent lamps and compact fluorescent lamps (CFLs) in offices, stores and homes. Because of its high density, it is also used in barometers and manometers. Due to its high rate of thermal expansion—which remains fairly constant over a wide temperature range—mercury is also used extensively in thermometers and thermostats. Mercury-vapor lamps, which emit light rich in ultraviolet radiation, are used for street lighting, in water treatment plants as a disinfectant, and in tanning beds. Mercury is used as an electrode in the production of chlorine and sodium hydroxide and in certain electric batteries. Mercury is important as an electrical contact for switches, and mercury conducts the charge in fluorescent lamps.

Exposure typically comes from inhaling mercury vapors. For most of us, fluorescent lamps present the single greatest risk of mercury exposure in the work place. A recent study of exposure to broken "low mercury" lamps by the New Jersey Department of Environmental Protection entitled "Release of Mercury from Broken Fluorescent Bulbs" demonstrated that "elevated airborne levels of mercury could exist in the vicinity of recently broken lamps, and "could exceed occupational exposure limits."

There is currently significant risk in transporting fluorescent lamps and CFLs, as there are no packaging standards and few regulations in place requiring proper packaging for storage and transportation. To protect against mercury vapor exposure from used fluorescent lamps and other mercury-containing devices, these products should be stored and transported in a packaging configuration proven to contain mercury vapor. One current design includes a vapor resistant and zip seal bag and is the only design that has proven effective in containing mercury vapor.

Raising Awareness of the Dangers of Mercury Vapor


As fluorescent lamps and CFLs increasingly become businesses and consumers’ primary lighting choice, more states are taking action to address the health and safety issues associated with their use. While fluorescent lamps are considered as a more energy-efficient bulb than traditional incandescent bulbs, these lamps are fragile and, upon breaking, release mercury vapor that can be detrimental to handlers' health—from those involved with handling new bulbs to people involved with storing, packaging and shipping used lamps.

To address the potential dangers of unsafe packaging and transportation of used fluorescent lamps and mercury containing devices, many states are taking a stand to increase awareness by enforcing their own legislation. In March 2010, Washington took the first step in creating a law that requires lights and other mercury-containing devices to be packaged and shipped in material that will minimize the release of mercury into the environment. The law also states that packages should include mercury vapor barrier materials if lamps are transported by the United States postal service or a common carrier or collected via curbside programs and mail-back businesses.

Additional states have addressed this health issue with their own, more specific regulations regarding lamp disposal, including Wisconsin, Minnesota, Massachusetts, California, Vermont, New York, Connecticut, Maine, New Hampshire, Florida and Rhode Island. To read about these laws and find out more information regarding state regulations, read our "Additional State Regulations" post.

Fluorescent Lamp Packaging: What is the Most Effective?


On average, CFLs and fluorescent lamps contain about 4 milligrams of mercury. Mercury is dangerous and can be a threat to our safety and health when exposed to it. It is important for consumers to take the necessary precautions when handling, storing or transporting used or broken lamps to protect themselves against any potential harm from released mercury vapor.

According to a study conducted by the University of Minnesota, there is only one proven packaging configuration that effectively contains mercury vapor from broken fluorescent lamps below permissible workplace exposure levels, as defined by state and federal authorities. This configuration consists of an outer cardboard layer, a bag to contain the mercury vapor and an inner layer of cardboard to prevent broken glass from puncturing the bag.

History of Universal Waste Containers


Universal waste containers that could be transported by common carrier were first introduced in 1998. The first containers were primarily used to ship fluorescent lighting. Initially, these containers were simple corrugated boxes, with some including a plastic bag inside the box. Since the contents were made of glass, they were designed primarily to contain the contents within the shipping container. However, since mercury begins to vaporize at 70 degrees F, packaging improvements were needed to address the issue of potential mercury vapor release in the event of breakage during accumulation and transport. Read more about packaging designed to contain mercury vapor.

Cleaning Up the Broken Bulb


As a result of a growing green movement and new government regulations—including an Act of Congress to cease the manufacture of incandescent lamps by 2013—the use of more energy efficient lights, such as CFLs, continues to increase. Like all fluorescent lights, CFLs contain hazardous mercury vapor, which is emitted when these fragile bulbs break and causes significant health and safety issues, as well as environmental concerns.

What should you do if a CFL breaks in your home? A Maine Compact Fluorescent Lamp Breakage Study found that mercury concentration in a room can exceed permissible exposure levels, even from the breakage of a single CFL.
