Industrial hygiene and safety evaluations and a health assessment of lead (7439-92-1) exposure were conducted during the demolition of two tenement buildings in the Bronx, New York. The tenement buildings were five and six stories, including the basement, which had been previously abandoned, and all windows and doors were sealed with cement block. Construction was prewar including wood floors and joists supported by perimeter brick walls. Blood lead screening was conducted twice on two workers. One had an initial reading of 16 micrograms/deciliter (microg/dl) which increased slightly by 2 microg/dl. The second worker had an initial reading of 30microg/dl which decreased by 6microg/dl. Airborne lead monitoring of site one showed an 8 hour time weighted average ranging from 0.003 mg/m3 to 0.011 mg/m3. At site two, the exposures ranged from 0.06 to 0.032 mg/m3. Total dust exposure for demolition workers ranged from 4.27 to 11.6 mg/m3. One respirable dust sample was taken at each location, 3.39 and 1.31 mg/m3. At the second site roofing material contained about 5 percent chrysotile (12001-29-5) asbestos. No respiratory protection was provided at either site and no hygiene facilities were available. No fall protection equipment or site security was provided.
