(1976) Storage Technology Corporation, Inc., Louisville and Broomfield, Colorado. (Click to open report) Exposure to N-methyldicyclohexylamine (7560830) (MCHA) was investigated at the Storage Technology Corporation (SIC-3573), Incorporated in Louisville and Broomfield, Colorado on October 13 and 14, 1975.

Requests for the survey were made by company management from both facilities. Personal and area air samples were collected and analyzed for various metallic dusts and pyrolysis products, in addition to MCHA and methylene-bisphenyl-isocyanate (101688) (MDI). The employees provided medical histories and any symptomatic workers were given physical examinations and clinical tests. Employees were exposed to toxic concentrations of MCHA as evidenced by common symptoms of nausea, dizziness, coughs, dry mouths and lips, headaches, and eye watering. Unpleasant odors and residual tastes and eye, throat, and chest irritations also were reported by workers at the polyurethane foam operation. Some of the symptoms were not verifiable by medical examination. There were no abnormal blood counts or blood samples. All environmental samples for MDI were below the evaluation criteria of 0.2 milligrams per cubic meter. MCHA was not detected; no exposure standard exists for this compound. The author concludes that no hazard exists at these facilities. Recommendations are made to improve ventilation at vapor exhaust sites, to provide respirators, and to medically monitor employees involved with polyurethane processes.

(1976) Syntex Fabrics, Inc., Williamsport, Pennsylvania. (Click to open report) A combined environmental medical evaluation conducted at the Syntex Fabrics (SIC-2241), Incorporated, Williamsport, Pennsylvania shows that a potential health hazard from exposure to dust containing cotton may exist to workers exposed in Area One of the Weaving Department. Although no case of byssinosis has occurred during eight weeks' operation of the weaving process, there is evidence that upper respiratory irritation is present to a greater degree in workers from Area One than in the surround...

Although no case of byssinosis has occurred during eight weeks' operation of the weaving process, there is evidence that upper respiratory irritation is present to a greater degree in workers from Area One than in the surrounding areas. Recommendations include the adoption of recommendations in the NIOSH Criteria Document for cotton dust by Syntex Fabrics, and audiometric testing and X-ray of the chest as part of pre-employment examination.

The survey was prompted by a request from a representative of the 53 affected employees regarding exposure to fiberglass dust during the manufacture of a fibrous glass reinforced, resin construction- insulation board. Visual observation of the manufacturing operation and medical interviews with the employees revealed that no health hazard existed from airborne fibrous glass. In view of the fact that no workers reported skin irritations and observations in-plant indicated very little contamination from fibrous glass, and for the most part, adequate ventilation, no health hazard was judged to exist as the product was used or found. Recommendations are made for improved exhaust ventilation.

(1976) TRW Incorporated, Philadelphia, Pennsylvania. (Click to open report) Environmental and medical health evaluation surveys were performed at the TRW electrical resistor manufacturing facility (SIC-3622) located in Philadelphia, Pa., via employee interviews, evaluation of ventilation systems, evaluation of work procedures and available toxicity information. The results obtained indicate that employee exposures to butyl-cellosolve (111762), ethyl-alcohol (64175), and xylene in the filament-draw department did not pose a health hazard at the concentrations measured du...

The results obtained indicate that employee exposures to butyl-cellosolve (111762), ethyl-alcohol (64175), and xylene in the filament-draw department did not pose a health hazard at the concentrations measured during this evaluation. Employees may, however, be exposed to potentially toxic concentrations of mercury (7439976). Exposures to trichloroethylene (79016) in the lead-heading room do not constitute a health hazard. Workers in the mold department were not exposed to toxic concentrations of phenol (108952) or nuisance dust. Employees exposures to xylene (1330207), 1,1,1-trichloroethane (71556), methyl-ethyl-ketone (78933) and toluene (108883) in the sub-assembly area did not constitute a health hazard. The plating room operator was not exposed to toxic levels of lead (7439921) or fluorides. The medical program at this TRW facility appears to be adequate. The program adheres to the medical criteria as recommended by NIOSH criteria documents. Appropriate biological monitoring and medical surveillance are being done. Medical interviews with workers revealed no work related health complaints. A review of company medical records also produced no significant findings.

(1976) U.S. Post Office, Chicago, Illinois. (Click to open report) A health hazard evaluation determination performed by NIOSH personnel at the main U.S. Post Office (SIC-4311) in Chicago revealed that no health hazard exists from dust as found in the work room air of mail bag handling areas. Air samples indicated a maximum personal exposure of less than 10 percent of the evaluation criteria for nuisance dust. Recommendations are made for the use of a sweeping compound during clean up operations.

(1976) W. R. Case and Sons Cutlery Company, Bradford, Pennsylvania. (Click to open report) A health hazard evaluation determination performed at a cutlery manufacturing plant (SIC-3421) revealed that employees at the hafting operation are exposed to concentrations of wood, cowhide and aluminum (1344281) oxide dusts in excess of the recommended levels of nuisance dust. The suspected relationship of wood dust and leather dust to excess nasal cancer mandates reduction of exposure to minimal or zero levels.

The survey was prompted by a request from an authorized representative of the approximately 25 affected employees regarding exposure to inhalation of dust during injection molding (SIC-3079) of epoxy resins. Environmental sampling, medical interviews, and examination of the skin of some of the workers revealed that although airborne concentrations of epoxy resin dust were not excessive in the work atmosphere, there is evidence of dermatitis in a few individuals which is probably job related. The causative agent is a black or grey epoxy resin purchased under different trade names. Information received from the management disclosed that no asbestos (1332214) was present. However, minute amounts of fibrous glass were incorporated in one of the resins. Concentrations of air contaminants were not excessive.

(1976) Western Roofing Company, Sellers and Marquis Roofing Company, A. J. Shirk Roofing Company, and the Quality Roofing Company, Kansas City, Missouri. (Click to open report) The results of a medical-environmental evaluation indicates that employees were exposed to toxic concentrations of particulate polycyclic organic matter during roofing operations involving the tear-off of a 7 acre roof (SIC-1761). The particulate polycyclic organic matter includes polynuclear aromatic hydrocarbons, benzo(a)pyrene (50328) and benzo(e)pyrene.

The particulate polycyclic organic matter includes polynuclear aromatic hydrocarbons, benzo(a)pyrene (50328) and benzo(e)pyrene. Seventy-one percent of all roofers examined gave a history of apparent skin photosensitivity attributed to pitch dust exposures during this project. Ninety-two percent of the examined Caucasian roofers working on this project gave a history of apparent skin photosensitivity attributed to pitch dust exposures occurring during this project. Sixty-five percent of the examined roofers working on this project were observed to have conjunctivitis attributed to pitch dust exposures occurring during this project. These symptoms included lacrimation, chemosis, blepharospasm, lid swelling and blepharitis and conjunctival erythema. There was a statistically significant association between the absence of conjunctivitis in workers exposed to concentrations of 0.11 milligrams per cubic meter of particulate or less and the presence of conjunctivitis in workers exposed to particulate concentrations of 0.18 milligrams per cubic meter or greater. At least 9 employees were exposed to particulate concentrations exceeding the recommended threshold limit values. It appears that the benzpyrene concentrations also exceeded the recommended levels.
