Disposal

P501: Dispose of contents and empty containers in accordance with local, regional and federal regulations. Emergency overview Immediate concerns AS SOLD the product is a plastic molding compound A plastic resin (polyester polymer) intimately mixed and compounded with one or more of a variety of organic and/or inorganic filling materials. When fully “cured” or reacted, the plastic resin is insoluble, infusible and binds the well- dispersed, embedded filling materials. Some particles of molding compound may be present in a size that constitutes a respirable dust. This respirable dust may contain one or more of the following materials: fibrous glass, mineral fillers that may contain small amounts of crystalline silica, wood flour and/or other organic fibers. Chronic inhalation of each of the above has been associated with fibrotic lung disease and may increase the risk of lung cancer, especially among smokers. AS USED during polymerization (e.g., curing of the product during normal processing) or decomposition, no significant gaseous byproducts are expected be evolved. Grinding or machining of cured molded material may create a dust that poses a respiratory hazard if inhaled (see above). Comments: Refer to Section 5 for additional information on combustible dust hazards and Section 11 for detailed information on health effects and symptoms.
