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.

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.

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.

From April 29 to May 1, 1975 a follow up sampling was conducted for respirable particulates in the stockhouse and cast floor areas. The evaluation was requested by an authorized representative of an unspecified number of employees. Personal and area air samples were collected by 10 millimeter nylon and 0.5 inch steel cyclones, respectively, and these were analyzed using the x-ray diffraction technique. Total dust samples of iron-oxide and free silica were obtained using closed faced three piece cassettes with filters which were measured gravimetrically for weight gain. The 1974 free silica personal air samples contained three exposures in the blast furnace area 4 times over the OSHA standard of 100 micrograms per cubic meter and 2 exposures in the stockhouse were 21 and 28 times over the federal standards. One crane operator was exposed to a nontoxic level of iron-oxide. Area samples were negative and carbon-monoxide, sulfur- dioxide (7446095), and iron-oxide were below detectable limits. The 1975 study for free silica in area sampling was negative in the cast floor and stockhouse. Exposures of 7 of 36 cast floor workers and 1 of 17 stockhouse workers were equal to air in excess of the NIOSH recommended free silica standard of 50 micrograms per cubic meter. Over half of all the samples were in excess of this NIOSH standard for exposure to free silica. The author concludes that both factory areas may expose workers to potentially toxic concentrations of respirable free silica. The author recommends medical screening of potential employees, medical examinations every 3 years, safety training, posting exposure areas, personal respirators, hygienic practices, and air monitoring.

(1975) Anaconda Company, Anaconda, Montana. (Click to open report) Significant health hazards from the fume or dust of copper (7440508), lead (7439921), zinc (7440666), and cadmium (7440439) are not found for most workers in the converter department of a copper smelter, but a potential hazard is cited for ore handlers and skull breakers from airborne lead. Airborne arsenic (7440382) concentrations may indicate a potential for arsenic-induced cancers. Eye and respiratory tract irritation may be the result of sulfur- dioxide (7446095).

The potential for worker exposures to vinyl-chloride monomer is demonstrated for operators throughout the process, although all levels are found to be less than the existing OSHA standard of 1.0 ppm for vinyl- chloride (75014). Levels of toxic particulates including heavy metals and free silica are found to be below hazardous levels. Recommendations include improved enclosures, increased ventilation, and regular maintenance of local exhaust systems at material dump stations; approved respiratory protection for exposure to asbestos and vinyl-chloride, and periodic environmental and medical monitoring of operations and employees.
