Toxic exposure to cleaning chemicals used at Associated Grocers, Inc. (SIC-5411), Seattle, Washington, was evaluated on February 22 and March 23, 1979 in response to a request from an authorized employee representative. Air samples were collected and analyzed for levels of sodium-hydroxide (1310732), isopropyl-alcohol (67630), and butyl cellosolve (111762). All were found to be within OSHA limits (2 milligrams per cubic meter of air, 400, and 50 parts per million parts of air, respectively). Toxic levels of sodium hydroxide were measured at a 500 gallon caustic solution tank (6.4 milligrams per cubic meters of air). A review of the medical records of four employees did not reveal any problems conclusively related to work. It is concluded that a hazard exists during use of the caustic solution tank, but not in relation to general environmental levels of chemicals. To reduce exposure to sodium hydroxide dust, it is recommended that a liquid concentrate, and granulated instead of powdered sodium-hydroxide be used. Also recommended is the use of protective clothing and gear, and the labeling of contents in the caustic tank.
