Environmental exposures to what was identified as VM-and-P-naphtha (8030306), and perchloroethylene (127184), acetic-acid (64197), and hydrogen-cyanide (74908) in the Printing Branch (SIC-2711) of the Federal Communications Commission in Washington, D.C. were evaluated on January 16 and 17, 1979. The evaluation was recommended following an inspection by the Federal Safety and Health Agency. VM- and-P-naphtha, perchloroethylene mixture, and acetic-acid samples were analyzed using a gas chromatograph with a flame ionization detector. Cyanide samples were analyzed using a cellulose membrane filter connected in series with an impinger. Airborne exposure evaluations show that VM-and-P-naphtha, perchloroethylene, hydrogen cyanide, and acetic-acid concentrations (58 to 242, 18 to 67, 3, and less than 0.2 milligrams of substance per cubic meter of air sampled, respectively) were less than OSHA standards (2950, 670, 11, and 25 milligrams of substance per cubic meter of air sampled, respectively). The supplying of impervious gloves to Printing Branch employees for roll cleaning and electrostatic solution mixing and application is recommended, along with the labeling of all containers in accordance with a proposed OSHA labeling standard.
