Dangers of Mercury Vapor

Mercury vapor can be detrimental to consumers’ and handlers’ health—from those involved with handling new fluorescent bulbs to people involved with storing, packaging and shipping used and broken lamps. Vapor released from shattered lamps can be contained in specifically designed mercury storage packages, but concentrations inside this packaging can remain dangerously high, creating a risk if the package is opened or perforated. The vapors can be captured within mercury-safe packages with the inclusion of a new, patent-pending adsorbent technology that effectively reduces vapor levels over periods of time.

A Study by NUCON International, Inc., a world-wide leader in providing gas, vapor and liquid phase adsorption solutions, found the adsorbent showed an immediate reduction of mercury vapors by nearly 60 percent after 15 minutes. After 12 hours, the reduction can reach more than 95 percent. This technology, recently announced at the Air & Waste Management Association’s Conference & Exhibition, provides consumers and transporters who come into contact with used CFLs a safe way to handle them. With the vapor contained and captured in safe packaging, consumers’ and handlers’ risks of vapor leaks or seepage are greatly reduced. Also, a small consumer-size recycling bag, available soon, will feature this technology and allow people to safely store three to four used lamps at home before taking them to a retailer or municipality that accepts CFLs for recycling.

What Are Permissible Mercury Vapor Exposure Limits?

We all know that mercury vapor can be detrimental to the health and safety of not only ourselves, but also to the environment. But 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]). 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.

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.

Would Your Office Benefit from 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 businesses must work to not only comply with these regulations, but also ensure the safety of all personnel in addition to protecting the environment.

Clean-Up Guide for CFLs and Fluorescent Bulbs

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.
