Compact Fluorescent Lamp - Breakage Danger
Maine Compact Fluorescent Lamp Breakage Study Report
February 2008
Executive Summary
Forty five (45) experimental trials where compact fluorescent lamps (CFLs) were broken in a small/ moderate sized room were conducted in May through September of 2007. Eighteen (18) trials, three trials each of six differing scenarios, were originally planned for this study; however, additional trials were added to attempt to more fully address potential cleanup concerns. Broken lamps were either not cleaned up, cleaned up using Maine Department of Environmental Protection (DEP) pre-study cleanup guidance, vacuumed, or cleaned up using variations of the pre-study cleanup guidance. The mercury concentrations at the five foot height (adult breathing zone) and one foot height (infant/toddler breathing zone)1 above the study room floor were continuously monitored. The most notable finding of the study was how variable the results can be depending on the type of lamp, level of ventilation and cleanup method.
The pre-study cleanup guidance was generally found to be sound, including the advice to not vacuum as part of the cleanup. However as a result of this study, the cleanup guidance was modified. The new cleanup guidance can be seen in Appendix E.
