Origins of the Phrase “Mad As a Hatter”

Mercury has long been known to be toxic. The phrase "mad as a hatter" refers to the 19th-century occupational disease that resulted from prolonged contact with the mercury used in the manufacture of felt hats. Along with felt hats, mercury has been taken out of many manufacturing processes and products—as the dangers of mercury exposure become more well known.

Most mercury pesticides have been withdrawn from the U.S. market, and many countries banned ocean dumping of mercury and other pollutants in 1972. Production of mercury-containing interior and exterior paints in the United States was phased out in 1991. Mercury, which has been used in medicines for hundreds of years, continues to be used in various folk remedies that can cause mercury exposures. The use of mercury in dental amalgam for tooth fillings has stirred escalating controversy in recent years. Most other medical uses have been banned or are being phased out.

Despite these changes, some workers today, especially laboratory technicians, nurses, and machine operators, continue to be exposed to mercury on the job. Elemental mercury (the silver liquid familiar in thermometers) is a common occupational source of exposure. Fragile fluorescent lamps and compact fluorescent lamps if broken represent another mercury exposure risk as they are handled by manufacturers, transporters, distributors, retailers, consumers and installers, as well as recycling or waste handlers. There are currently no universally enforced packaging standards designed to protect these people. There now exists a proven packaging design with a vapor resistant and zip seal bag that should be mandated to protect people who work with or near fluorescent lamps, as well as for protecting the surrounding environment.

Which States Are 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.

Why is it Important to Recycle Used Fluorescent Lamps?

According to EPA estimates, only 20% to 25% of used fluorescent lamps are recycled, These lamps are commonly sent to a recycler in bulk or in pre-paid shipping recycling boxes. The 75% to 80% of fluorescent lamps that are not recycled usually end up in dumpsters or trash containers and, ultimately, in landfills. One study indicates dumpsters that contain broken fluorescent lamps “strongly and persistently” emit mercury.(1) Another study on mercury release from broken fluorescent lamps found that between 17% to 40% of the mercury in broken low-mercury fluorescent lamps is released to the air during the two-week period after breakage.(2) Of this mercury, one-third of the release takes place during the first eight hours following breakage, potentially exposing personnel in the vicinity to unsafe levels of mercury vapor. Using this estimated release rate and an estimated 620 million lamps discarded annually in the United States, broken used fluorescent lamps release approximately two to four tons of mercury each year into the environment.

Used fluorescent lamps need to be properly handled during shipping and recycling. Safe packaging reduces the threat of mercury vapor emitted from broken lamps.

What Mercury?

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.

While some steps have been taken to encourage safe recycling and disposal of fluorescent lamps, this fact remains: although a variety of containers are marketed for transportation of fluorescent lamps, many don't provide necessary levels of protection against mercury vapor in the occurrence of breakage. Using a proven packaging design with a vapor resistant lining is vital to ensuring the safety of persons who work with or near fluorescent bulbs, as well as for protecting the surrounding environment, especially as fluorescent lighting continues to grow in popularity and practicality. Currently, only one package design, which includes a vapor resistant and zip seal bag, has proven effective in containing mercury vapor.

How To Minimize Health & Safety Risks of Used Fluorescent Lamps: Storage

One broken 48-inch fluorescent lamp in a small room or vehicle can release enough mercury vapor to exceed the Federal Occupational Health and Safety Administration (OSHA) permissible exposure limit (PEL). This means that 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.

Often, maintenance workers at small to large facilities store used lamps for a period of time until numerous lamps are collected for transportation to recycling facilities. Stored lamps may be bumped around and broken, so maintenance workers should package used lamps in a configuration proven to contain mercury vapor emissions. A recent study from the University of Minnesota indicates that three layers of packaging are necessary to provide sufficient containment of mercury vapor. An outer cardboard layer provides structure to the configuration and protects contents from outside elements. A bag positioned between two cardboard layers should feature a suitable material and tight seal—such as a unique zip closure foil-plastic laminate bag—to contain the mercury vapor. Finally, an inner layer of cardboard prevents broken glass from piercing the bag.

The First Waste Container

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.

Layers of Packaging: How Many Are Really Needed?

A study conducted at the University of Minnesota by a team of researchers found that common cardboard packages for fluorescent lamps do not contain mercury vapor below permissible workplace exposure levels, as defined by state and federal authorities.

The study tested packaging configurations that enhance this single cardboard layer with a plastic bag, as well as packages that add a second layer of cardboard to the design—with the bags positioned between the two cardboard layers. The latter group contained two package varieties: a double-box with a thicker, tape-sealed plastic bag, and a double box with a foil-plastic laminate bag containing a zip closure. Both of these packages performed better than the other configurations. Yet, only the double box with the foil-plastic laminate bag delivered the necessary levels of protection.

This study indicates that all three layers of the last packaging configuration are critical in the effective containment of mercury vapor. The first cardboard layer provides structure to the configuration and protects contents from outside elements. The bag—which should feature a suitable material and tight seal—contains the mercury vapor, and the inner layer of cardboard prevents broken glass from puncturing the bag and rendering it ineffective.

Packaging Used or Broken Fluorescent Bulbs

How do you effectively package used or broken fluorescent bulbs to prevent hazardous mercury vapor from emitting into your home or office? Is there a right or wrong way? Before you think about simply throwing that old bulb in the trash, read this post!

According to research studies, three layers of packaging are needed to sufficiently contain mercury vapor found in fluorescent lamps. The first is a cardboard layer, which provides structure to the configuration and protects contents from outside elements. The second layer consists of a bag—which should feature a suitable material and tight seal—which is used to contain the mercury vapor. The last, inner layer is also cardboard, which prevents broken glass from puncturing the bag and rendering it ineffective.

Next time you have a broken or burned out fluorescent bulb, use the above method to ensure you aren’t harming yourself or others with mercury vapor.

Incandescent Light Bulbs Gone for Good?

Store shelves containing primarily incandescent light bulbs are a rare sight these days, due to the 2007 energy conservation measure passed by Congress. This measure set standards to essentially ban incandescent lights by 2013, requiring households to make the switch to more energy efficient lights. With incandescents out, fluorescent lamps and CFLs continue to grow in popularity, providing energy and greenhouse gas emission savings.

However, even though fluorescent lamps and CFLs have proven their energy savings, many consumers are worried about their mercury levels and the potential health, safety and environmental issues caused by mercury vapor emitted from broken lamps. With proper storage, transportation and disposal, fluorescent lights can be a green and safe lighting solution. Learn more about safe packaging, and get ready to make the switch.

When is Mercury Vapor Considered Unsafe?

We all know by now that mercury vapor can be a potential health and safety threat if it gets into our homes. But, at what point is mercury vapor considered unsafe?

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. Recent research has shown that only one current package design which includes a vapor resistant and zip seal bag has proven effective in containing mercury vapor.

Benefit From Energy-Efficient Fluorescent Lamps While Preventing Against Health & Safety Hazards

Fluorescent lamps have increased in popularity, due to rising energy costs and environmental concerns. Fluorescent lamps are four to six times more efficient than incandescent lamps, which in turn reduces the power demand from local utilities. Since most power stations use coal as a source for electrical generation, they are large emitters of both greenhouse gas and mercury, which is naturally occurring in most coal that is used today. The reduced demand for electricity in turn reduces both greenhouse gas and mercury emissions.

However, fluorescent lamps are fragile and, upon breaking, these lamps 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.

While a variety of containers are marketed for transportation of fluorescent lamps, many don't provide sufficient protection against mercury vapor emitted from broken lamps. Using a proven packaging design is vital to ensuring the safety of people who handle these lamps, as well as maintaining their green benefits.

Fluorescent Lamp Transportation Regulation

The U.S. Department of Transportation (DOT) provides packaging standards for the transportation of fluorescent lamps (referred to in the regulations as “mercury vapor tubes”). Those regulations require that shipments of lamps be contained in packaging that prevents the escape of mercury.

However, those DOT packaging requirements will rarely, if ever, apply to packages of used mercury-containing lamps. Based on the rules and the mercury content of used lamps, the DOT standards only apply to packages containing more than 250 typical CFLs or low mercury fluorescent lamps or 100–200 other types of fluorescent lamps. Most used lamps are transported in far smaller containers. Yet even a single broken lamp can emit mercury vapor beyond permissible exposure levels.

One broken 48-inch fluorescent lamp in a small room or vehicle can release enough mercury vapor to exceed the Federal OSHA PEL. This 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.

Researchers Confirm Fluorescent Bulb Packaging Requires Three Layers

A recent study conducted at the University of Minnesota suggests that most containers used for storage and transportation of used fluorescent lamps to recycling centers do not sufficiently prevent the release of mercury vapor from broken lamps.

This study measured the performance of five different packages in three categories of commercially available containers employed for storage and transport of used fluorescent lamps. The first configuration was a single cardboard box, much like the packages new fluorescent lamps are sold in that are often reused as disposal packages. The second category included single boxes paired with a plastic bag—with one box from this group featuring an unsealed, thin plastic liner and the other a tape-sealed plastic bag. The third group of boxes consisted of a double-box design with a bag positioned between the two cardboard layers. One of these double-box designs used a thicker, tape-sealed plastic bag, and the second featured a foil-plastic laminate bag with a zip closure.

Each test package was loaded with 40 used fluorescent lamps , which were then broken by dropping and shaking the package inside a test chamber. Researchers then measured the level of mercury vapor inside the chamber for a six-hour period. Researchers concluded that each of the three layers performs a specific function. The inner cardboard layer prevents the broken glass from puncturing the bag, which contains the vapor. The outer box serves as a protective layer for all contents and also provides structure to the configuration.

EPA Packaging Regulations

Shipping, packaging, and handling of fluorescent lamps is a major concern because of the harmful mercury vapor emitted when the lamps are broken, which commonly occurs during shipment. To lessen the health and environmental risks associated with mercury vapor, national laws--sometimes supplemented by more rigorous state laws--exist to encourage proper recycling of fluorescent lamps. EPA encourages recycling of these lamps by allowing common carrier shipment to recycling facilities. To protect people who handle fluorescent lamps, EPA instructs that packaging should be designed to protect against breakage. While the rules mandate that lamps be packaged in structurally sound packages, the federal laws don't explicitly address mercury vapor release.

State and Federal Packaging Rules and Regulations

Federal regulations do not currently mandate the use of packaging designed to prevent the loss of mercury vapor. However, this may not continue to be the case. As the awareness of the dangers of mercury vapor increases, so have the federal and state rules that regulate its disposal.

In 1999, the Environmental Protection Agency (EPA) established environmental and transportation regulations, including packaging requirements for fluorescent lamps. They require lamps to be managed in containers designed to prevent breakage. However, they do not require the container to be designed to prevent the loss of mercury vapor. In 2005, the EPA added a requirement mandating that packaging be designed to prevent mercury from escaping into the environment.

The state of Washington recently signed Senate Bill 5543, making this state the first to address the dangers of unsafe packaging and transportation of used fluorescent lamps, as well as other mercury containing devices. Due to the ineffective nature of most packaging configurations utilized for shipping used fluorescent lamps, the new law mandates that these devices are packaged and shipped in material that will minimize the release of mercury into the environment. The law additionally requires packages to include mercury vapor barrier materials if lamps are transported by the United States postal service, a common carrier, or collected via curbside programs and mail-back businesses. Washington has set the precursor for additional states to follow. Read more about additional state regulations regarding safe packaging of used fluorescent lamps.

Minimize Safety, Health and Environmental Risks of Used Fluorescent Lamps: Transport

Fluorescent lamps release an estimated one ton of mercury into the air each year in the US alone, and transportation of used lamps may be a significant source of emissions. According to estimates derived from modeling, four percent of mercury air emissions from all products were from fluorescent lamps in 2005—with higher mercury emissions taking place during waste lamp transport than during disposal processes. (1) Measurements of mercury emissions from dumpsters and from transfer station activities support the evidence that transportation of used lamps results in significant mercury vapor emissions. (2)

According to these findings, many used lamps are broken en route to recycling facilities, negating environmental efforts before the lamps even arrive at their final destination. To prevent the release of mercury vapor during the often-rough treks to recycling facilities, lamps should also be transported in packages proven to contain mercury vapor.

Three Layers For a Safe Package

According to a recent study conducted at the University of Minnesota's School of Public Health, most containers used for storage and transportation of used fluorescent lamps to recycling centers do not sufficiently prevent the release of mercury vapor from broken lamps.(1) The results show that a double-box design with a foil-plastic laminate bag with a zip closure bag positioned between the two cardboard layers minimized airborne mercury vapor levels below all current federal and state workplace exposure regulations and guidelines.

Researchers concluded that each of the three layers performs a specific function. The inner cardboard layer prevents the broken glass from puncturing the bag, which contains the vapor. The outer box serves as a protective layer for all contents and also provides structure to the configuration. Packages must contain all three of the layers described above to effectively contain harmful mercury vapor emissions.
