The purpose of this report is to document the evaluation of the public health effects of the air emissions from the Central Garden and Pet Supply Warehouse fire that was verbally provided during the response efforts to the fire event. The facility contained a variety of lawn and garden supplies including pesticides, herbicides, and pool maintenance chemicals. The fire also involved a portion of a pharmaceutical supply firm which contained medical supplies ranging from liquid and pill-form medicines to sterile syringes and other physical supplies.

The W.R. Grace facility in Phoenix, Arizona, received vermiculite concentrate from the Libby, Montana, vermiculite mine. W.R. Grace Company has owned and operated the Arizona site since 1964. In 1964 W.R. Grace purchased the company that had previously occupied the site and, following the relocation of its vermiculite exfoliation furnace from Glendale, Arizona, began processing vermiculite concentrate and marketing it under the Zonolite® brand. The objective of this health consultation is to evaluate exposure pathways and potential health effects in those persons who, between 1964 and 2002, may have been exposed to Libby asbestos as a result of vermiculite concentrate processing activities and waste materials from the W.R. Grace exfoliation facility in Phoenix.
