HHE Report No. HHE-78-104-102, Evaluation of Flocculant Agents, Lundale, West Virgina.
NIOSH 1978 Dec:2 pages
Worker exposures to the flocculant agents, Superfloc-204 and Superfloc-206 were evaluated at the Buffalo Mining Company's Preparation Facility (SIC-1111), in Lundale, West Virginia, on September 22, 1978. An unidentified individual requested the evaluation on behalf of an unspecified number of workers, work processes and hygienic practices were reviewed. The chemicals were used in powder form and were manually scoped from the bag with a tin can and poured into a mixing basin through a plastic funnel. No protective equipment was used. The author concludes that the exposure was intermittent and minimal and that polyacrylamide pose little or no health problems to the normal individual, and consequently no health hazard from exposure to these polyacrylamides existed at this facility. She recommends the installation of an automatic dry or liquid chemical feeder to minimize worker contact with the chemicals, and the use of the chemicals in a liquid, rather than solid form, to eliminate dust generation.
