Health Hazard Evaluations (HHEs)

(1973) PPG Industries, Inc., Clarksburg, West Virginia. (Click to open report)
Air sampling and medical evaluation performed at a glass cutting and packaging operation reveals that salicylic dust, a component of Polytek glass used in the process, is toxic at the concentration used or found, causing acute irritation of the eyes, nose and throat of the workers exposed. Air concentration levels of 0.08 mg per cubic meter of salicylic-acid (69727) does not cause significant blood levels of the compound, but it does induce symptoms. Limited evaluation of the new Polytek dispens...

Air concentration levels of 0.08 mg per cubic meter of salicylic-acid (69727) does not cause significant blood levels of the compound, but it does induce symptoms. Limited evaluation of the new Polytek dispenser operation has shown a significant reduction in symptomatology. (Click to show less)

(1973) Reynolds Metals Company, Bauxite, Arkansas. (Click to open report)
Air sampling and medical investigations at an industry manufacturing alumina (1344281) from bauxite indicate that alumina dust and sinter dust are toxic at the concentrations found during the evaluation, while crystalline silica and fluorides in the cryolite area are not toxic in the concentrations measured. Workers in the alumina bagging area noted occasional burning of the nose and had a history of skin irritation, although dermatitis was well controlled by the use of protective creams.

(1973) Steel Tool and Engineering Company, Taylor, Michigan. (Click to open report)
Evaluation of hazards from exposure to dusts from grinding and sandblasting operations, heat, degreasing operations, solvent test operations, and "Acryloid" glue operations, in the manufacture of high temperature alloy components (SIC-349) for the gas turbine industry. Evaluation also covers exposure to dusts of chromium (7440473), cobalt (7440484), molybdenum (7439987), nickel (7440020), and iron (7439896). Solvents involved in the operations are ethylene-dichloride (107062), acetone, 1,1,1-tri...

Evaluation also covers exposure to dusts of chromium (7440473), cobalt (7440484), molybdenum (7439987), nickel (7440020), and iron (7439896). Solvents involved in the operations are ethylene-dichloride (107062), acetone, 1,1,1-trichloroethane (25323891) and trichloroethylene (79016). Data are given for the evaluation design and evaluation methods, 8-hour time weighted concentration, and pathological effects of various types of dusts. Toxic effects of the metals and chemicals include cancer of the lung, nose, and sinus, pneumonitis, mucosal irritation, ciderosis, irritation of the eyes and nose, narcosis, headaches, dizziness, vertigo, tremors, nausea, vomiting, insomnia, fatigue, liver damage and lightheadedness. Environmental survey results are given for grinding area, acryloid area, degreasing area, and furnace area with recommendations for each area based on medical survey results. (Click to show less)

(1973) The Budd Company, Automotive Division, Clinton, Michigan. (Click to open report)
Evaluation of the potential hazards associated with the use of cutting oil coolants utilized in drilling, milling, grinding, and other machining operations in the production of automobile and disc brakes in an automotive company. Eighty air samples are collected and 230 analytical determinations made to complete the survey. Eight hour time-weighted concentrations are given for oil mist, iron (7439896) as iron-oxide (1332372), total dust, 1,1,1-trichloroethane (25323891), tetrachloroethylene (127...

Eighty air samples are collected and 230 analytical determinations made to complete the survey. Eight hour time-weighted concentrations are given for oil mist, iron (7439896) as iron-oxide (1332372), total dust, 1,1,1-trichloroethane (25323891), tetrachloroethylene (127184), toluene (108883), xylene (95476), and ozone (10028156), as also the toxic effects of the substances. Hazards of physical agents are also given including the effects of noise over 90 decibels, and heat over 80 degrees-F. Recommendations include improvement of ventilation to reduce oil mists in the areas of highest concentrations and dermatitis incidence, wearing of long sleeved shirts with close fitting cuffs and clean uniforms, expansion of the hearing conservation program, audiometric examination, preemployment medical checkups, and elimination of noise at source through engineering controls.

(1973) Union Pacific Railroad, Pocatello, Idaho. (Click to open report)
Review of the toxic hazards of acrolein (107028), carbon-monoxide (630080), formaldehyde (50000), nitrogen-dioxide (10102440) and other oxides of nitrogen, sulfur-dioxide (7446095), and nuisance particulates. Topics include sampling methods and procedures, sample location and background information, medical evaluation through questionnaire, spirometry, and chest x-ray.

Topics include sampling methods and procedures, sample location and background information, medical evaluation through questionnaire, spirometry, and chest x-ray. Exposure to all the substances evaluated in the servicing division of the railroad company surveyed is found to be below OSHA standards. Eye irritation may occur for short periods depending on the condition of the units. Excessive chronic respiratory disease is considered unlikely. Recommendations include shutting off the engines whenever possible during the servicing period. (Click to show less)
