Health Hazard Evaluation Report HETA 96-0140-2606, Philadelphia School District,Franklin Learning Center, Philadelphia, Pennsylvania

摘要

In response to a request from the Philadelphia Federation of Teachers, aninvestigation was begun into possible exposure to lead (7439921) at the Franklin Learning Center (SIC-8211), Philadelphia, Pennsylvania. The building was about 85 years old. There were about 90 employees; blood lead tests and hand wipe sampling were performed on 45. Water sampling showed lead concentrations less than the 3 parts per billion (ppb). Surface wipe samples were collected from floors, desks, and window sills. Window sills in nonabated and abated areas were sampled. Dust lead loadings exceeded HUD guidelines on 26% of all window sills sampled. Floors in nonabated and abated areas were also sampled with HUD guidelines for lead on floors being exceeded in 17 of the nonabated and three of the abated areas. Dust lead loading on desktops ranged up to 230 micrograms/square foot. Wipe samples from hands of employees contained from 2 to 160 micrograms lead. All blood lead levels were low, ranging from 0.6 to 5.6 micrograms per deciliter. While severe peeling of lead based paint was found and significant dust lead loadings were present, the authors conclude that a hazard from lead exposure was not found at the school for the staff.
