A bulk sample of Zorb-All, a drying agent used to remove moisture and liquids from the dock floor of the Commercial Lovelace Company (SIC-4463) freight terminal in Dayton, Ohio was collected on March 7, 1979. The sampling was prompted by a request from an authorized representative of the Teamsters Union to determine the potential toxic effects of the agent. X-ray analysis of the approximately 6 percent amount of free crystalline-silica (quartz) (14808607) contained in the sample shows that silica (7631869), potassium (7440097), calcium (7440702), titanium (7440326), iron (7439896), and aluminum (7429905) were the major constituents of this substance. It is concluded that Zorb-All is not hazardous to dock workers at the terminal because of its low content of toxic material and large particle size. It is recommended that the agent be cleaned up after its use before a dry powder residue is formed, which might become airborne and cause irritation of the eyes, nose, or throat.
