Health Hazard Evaluation Report HETA 84-172-1573, Philadelphia Limerick Power Plant, Pottstown, Pennsylvania

Environmental and breathing-zone samples were analyzed for formaldehyde and particulates at the Philadelphia Electric Limerick power facility construction site, Pottstown, Pennsylvania in April, 1980. The survey was requested by the union to evaluate exposure to an insulating material containing ammonium-phosphate, fiberglass, and long chain hydrocarbons, because of complaints of respiratory irritation. The authors conclude that a health hazard does not exist at the site. This insulation may be associated with symptoms of mucosal and airway irritation when used in confined spaces. Recommendations include using portable exhaust systems and developing joint management/union education programs dealing with workplace contaminants.
