Table 5 summarizes the average concentrations for five Maine clean-up scenarios (S2–S6) that all utilized the same type of ‘‘Brand A’’ CFL. The five clean-up scenarios (S2–S6) involved different flooring materials, ventilations, and clean-up using Maine DEP existing clean-up guidance, vacuumed, or cleaned up using variations of the exiting clean-up guidance. Air was continuously sampled at 1-ft (0.3 m) and 5-ft (1.5 m) heights directly above the CFL breakage site. Results from Stahler et al. Scenarios S2–S6 are relevant to the second scenario of interest. All five of the Stahler et al. (2008) scenarios used the same brand and wattage (Brand A, 14 W) CFL, the same initial clean-up measures, and for each scenario a window was open.
