Health Hazard Evaluation Determination Report No. 77-125-547, Amphenol Cadre, Longmont, Colorado

摘要

Breathing zone concentrations of methyl ethyl ketone (CAS 78-93-3) (MEK), toluene (CAS 108-88-3), an xylene (CAS 1330-20-7), and general room air concentration of 4,4'-methylene bis (2-chloroaniline) (CAS 101-14-4) (MOCA) and toluene-2,4-diisocyanate (CAS 26471-62-5) (TDI) were measured at amphenol Cadre (SIC-3694) in Longmont, Colorado on March 2 and April 20, 1978. An evaluation request was received from an authorized representative of the employees to evaluate the potential exposure of 20 employees to solvents and paint sprays used in the facility. TDI, MOCA, toluene and xylene concentrations were below laboratory limits of detection. Only one MEK sample exceeded the OSHA standard of 590 milligrams per cubic meter for an 8 hour time weighed average exposure. The authors conclude that a potential health hazard exists from exposurer to MEK. They recommend that solvents be placed in safety dispensing cans, eating in the work area be prohibited, and appropriate warnings be placed in the area where MOCA is used.
