NIOSH Health Hazard Evaluation Report: HETA No. 2000-0308-2981, Ikens Hardwood Floor Services, Madison, Wisconsin, September 2005

摘要

In May 2000, the National Institute for Occupational Safety and Health received a health hazard evaluation (HHE) request from management at Ikens Hardwood Floor Services, Madison, Wisconsin. The request concerned potential lead and wood dust exposures during wood floor refinishing. The floor service company had previously evaluated 41various floor finishes for lead content; among these, 15% exceeded the federal action level for lead-based paint (0.5% lead by weight). NIOSH investigators conducted a site visit in June 2000 at a single-family home in Madison, Wisconsin, where Ikens Hardwood Floor Services was refinishing hardwood floors. General area and personal breathing-zone (PBZ) air samples were collected for lead and wood dust during floor refinishing, and settled dust samples were measured for lead content. Four in situ (in place) surface measurements were taken to measure the lead content in the varnish on floors.
