(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. Seventy-one percent of all roofers examined gave a history of apparent skin photosensitivity attributed to pitch dust exposures during this ...

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.

(1976) Wheeling Pittsburgh Steel Corporation, Steubenville, Ohio. (Click to open report) Exposures to coal-tar-pitch, iron-oxide (1345251), carbon- monoxide (630080), silica (7631869), graphite (7782425), manganese (7439965), calcium-oxide (1305788), and dust were investigated in various work areas of the Wheeling Pittsburgh Steel Corporation (SIC- 3325) in Steubenville, Ohio on April 25, 1974. 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 representativ...

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).

(1975) Armstrong Cork Company, Jackson, Mississippi. (Click to open report) Exposure to airborne chrysotile asbestos in excess of the proposed OSHA standard of 0.5 fiber per cubic centimeter is found in a section of the Armstrong Cork Company (SIC-2499), Jackson, Mississippi, manufacturers of vinyl asbestos tiles. 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).

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.

(1975) Beltx Corporation, Antonia, Missouri. (Click to open report) Lint and other dust, generated during sewing and similar operations utilizing nylon stretch knit or lace, nylon non-run, and acetate non-run tricot textile fabrics are cited as not toxic at concentrations measured in the panty department. Lint or other nuisance dust may occasionally aggravate certain pre-existing medical conditions such as sinusitis or atopic dermatitis, and contribute to the discomfort of these conditions.

(Click to open report) Environmental and medical evaluation of methyl-methacrylate (80626) exposure during mixing of liquid resin and when machining hardened resin reveals that present levels are not toxic. Evidence of past toxic exposure is evidenced by dermatitis and facial swelling. Recommendation is made for providing makeup air when the laboratory hood fan is operating.

(1975) Converse Rubber Company, Malden, Massachusetts. (Click to open report) Environmental surveys and employee interviews conducted at the Converse Rubber Company (SIC-3021) indicate that compounders in the doubling room are exposed to excessive concentrations of airborne particulates and that brief periodic exposures to higher concentrations of zinc (7440666) stearate may produce irritation of the upper respiratory tract. Ammonia (7664417) concentrations measured are also determined to be capable of producing sensory irritation.

(1975) Dunlop Tire and Rubber Company, Huntsville, Alabama. (Click to open report) Environmental and medical evaluations of a plant manufacturing automotive tires reveal levels of zinc-oxide (1314132), manganese (7439965), and copper (7440508) are non-toxic; however, a high concentration of particulate dusts of unknown toxicity is determined to present a potential hazard. Recommendations are presented for control of particulate dust and for the prevention of possible contact dermatitis.
