Health hazard evaluation report: HETA-91-0354-2532, South Dade Disposal Site, Goulds, Florida.
NIOSH 1995 Sep; :1-40
In response to a request from the American Federation of State, County, and Municipal Employees, an investigation was begun into possible workplace exposures related to waste shredding operations at the South Dade Disposal Site (SIC-4953), Goulds, Florida. Employees had reported rashes, eye problems, and respiratory difficulty. Eight months after the initial request and visit, an additional request for a study was initiated. During this second investigation at the site, Hurricane Andrew destroyed much of the facility and the surrounding community, thus limiting the study. Personal breathing zone samples ranged from 0.33 to 22.1mg/m3 for total welding fume. Personal chromium (7440473) exposures ranged from 1 to 81microg/m3. In ten of 15 samples, nickel (7440020) was detected on both welders and support personnel. Personal exposure to nickel ranged up to 16microg/m3. One carbon-monoxide (630080) sample taken exceeded the suggested limits. In 11 of 18 samples, sulfur-dioxide (7446095) was detected on both welders and support personnel; in 17 of 18 samples, nitrogen-dioxide (10102440) was detected. The authors conclude that welders had the greatest potential to be overexposed to total welding fume, chromium, and nickel. They noted also that the lack of engineering controls contributed greatly to these over exposures.
