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.

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. 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.

According to these findings, many used lamps are broken en route to recycling facilities, negating facility managers’ 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.

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.

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

Following the proper clean-up and disposal policies is necessary in ensuring the safety of people who handle fluorescent lamps, as well as those in close proximity to them. However, proper disposal of used lamps is not as simple as dropping them in a recycling bin. Lamps must be carefully removed and handled, as well as stored and transported in a package proven to contain mercury vapor. Specific precautions should be taken during each of the following steps: Handling, Storage, Transport, Recycling and Breakage.

Handling:

Mercury vapor—which can get into water, contaminating fish and entering the human food chain—can cause neurological damage to adults, children and fetuses. To avoid these issues, lamps should be carefully installed and uninstalled by maintenance professionals. Anyone handling a fluorescent bulb should take caution, as these lamps are fragile and can shatter easily.

Where do Fluorescent Lamps Go After They are Recycled?

Recycled lamps are sent to a recycling facility via truck, UPS or FedEx® in bulk or in pre-paid shipping recycling boxes, such as the Waste Management® LampTracker® system, which is specifically designed to accommodate various sized lamps and effectively contain mercury vapor emitted from broken lamps.

Once received, the recycler crushes the lamps, along with other contaminated products, devices and debris, to safely exhaust the mercury vapor and extract and reuse the resultant mercury—ensuring mercury is not released into the environment. The remaining debris is then placed in 55-gallon drums and sent to a retort facility—where the drums are heated to high temperatures to eliminate any remaining mercury. Any remaining glass and aluminum is furthered recycled and reused.

This process reduces the potential dangers of mercury vapor emitted from used fluorescent lamps—effectively reducing environmental liability and protecting both handlers and consumers from potential safety hazards and health risks.

What Happens When the Bulb Breaks?

When a fluorescent lamp breaks, it emits mercury vapor, which can cause severe health and safety risks. Mercury vapor, which can be absorbed through the skin or inhaled, can cause neurological damage to adults, children and fetuses. It is considered a persistent bioaccumulative toxic chemical, since it doesn't degrade in the environment. When mercury vapor gets into water, it is converted to methyl mercury and can enter the food chain through fish.

To avoid both health and environmental risks associated with mercury vapor emissions from broken fluorescent lamps, they should be packaged, stored and transported to recycling facilities in a configuration that is specifically designed to contain mercury vapor—and proven to be effective. To learn more about this configuration, read our Layers of protection: Packaging used fluorescent lamps post.

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.
