The United Auto Workers requested an investigation be made of respiratory system complaints at Orbitron Products (SIC-3714), Delphos, Ohio. Industrial, home, and automotive products were manufactured at the facility by approximately 80 employees. Ethyl- cyanoacrylate (7085850) was the primary chemical to which exposure was possible, but there was also concern about methyl-ethyl-ketone (78933) (MEK) exposure. Airborne exposure to MEK ranged from 17 to 430mg/m3. The NIOSH recommended exposure limit for this substance is 590mg/m3 for up to a 10 hour work day for a 40 hour work week. Ethyl-cyanoacrylate vapors were vented through exhaust hoods once the items glued with the substance were placed on boards to dry. Vapors given off during application of the adhesive were not subject to control and ranged in concentration from nondetectable to 1.6mg/m3. Workers sometimes ran out of space on the drying boards and left freshly glued items to dry outside the reach of the exhaust hoods. The low dilutions of ethyl-cyanoacrylate found were primarily due to the powerful floor fans used for cooling the workplace. A questionnaire was completed by 73 workers, of whom 19 reported wheezing or whistling breath, 16 reported episodes of shortness of breath and 15 reported chest tightness. Eight workers were considered to have occupational asthma. The authors conclude that it is not possible to determine whether exposures to ethyl- cyanoacrylate resulted in occupational asthma in the workers. The authors recommend that exposures to ethyl-cyanoacrylate be reduced.
