The cost of the HEPA/vaccine plan includes $75/h for each Hazmat worker, who spends 4 h per 10-h shift vacuuming and the remaining 6 h resting, rehydrating, and handling protective gear; a $250 portable HEPA air cleaner for each 12x12x8-ft room; $25 for each environmental sample, which includes the costs for sampling, shipping, and laboratory testing; and $20 to vaccinate each person.
The mean remediation time ranges from 2.9 years to 39.3 years; since there are approximately 4 million rooms and vacuuming can be done at the total rate of 2,000 rooms/day, it would take 5.5 years to clean each room once.
In recent research conducted by the California Department of Health Services (CDHS) using several types of non-HEPA household vacuum cleaners (canisters, shop, and uprights), no detectable airborne lead levels (< 0.5 [micro]g/[m.sup.3]) were observed after vacuuming
vinyl floors in housing units with lead loadings up to 800 [micro]g/[ft.sup.2] (Wall S.
Spend more time and effort cleaning and vacuuming

During these observations, an employment specialist observed Jesse while he was vacuuming
and noted any interactions or assistance from Carole.
Bed samples were collected by vacuuming
an area of 2 [m.sup.2] (the approximate area of a single twin-size bed) for a total of 5 min as follows: 1 min on one side of the pillow (over the pillowcase, if present); 2 min divided equally among the layers of blankets, sheets, and pads; and 2 min on the mattress surface.
Artifacts featured in the showcase include a 1960s' Jetsons' comic book featuring Rosey the robotic maid doing the vacuuming

Deep, soil-extraction vacuuming
is the result of a patented, dual brush/vacuum intake construction, which features two counter-rotating 4[inches]-diameter brushes.
