HHE determination report no. HHE-78-40-558, Landolite Inc., Fort Collins, Colorado.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HHE 78-40-558, 1979 Jan; :1-7
Environmental surveys were conducted on May 4, and August 15, 1978, to evaluate potential exposures associated with solvents, paints, and glues used throughout the Landolite, Incorporated (SIC-3069) facility in Fort Collins, Colorado. The evaluation was requested by the owner on behalf of three affected employees. Methyl ethyl ketone (78933) (MEK) concentrations ranged from 784 to 1,953 milligrams per cubic meter (mg/cu m) on the May 4 visit, exceeding the 590mg/cu m OSHA standard. MEK sample concentrations were below OSHA standards on the August 15 visit. Methyl isobutyl ketone (108101) (MIBK) and toluene (108883) concentrations were below OSHA standards on both visits. The author concludes that workers were overexposed to MEK on May 4, 1978, that worker reported symptoms were consistent with overexposure to MEK, MIBK, and toluene, and the extremely high concentrations that were found did pose a health hazard even for short time exposures. A health hazard did not exist on August 15, 1978, when the ventilation system was working properly. The author recommends that solvents be placed in safety dispensing cans, eating be prohibited in the work area, and local exhaust ventilation be placed more directly in line with the glueing and painting operations.
