The survey was prompted by a request from the employer regarding the presence of potentially toxic concentrations of any of the substances found in the place of employment. Based on environmental sampling, ventilation measurements, observation of work practices and medical questionnaires administered to the 27 affected employees it was established that with one exception, all welders in the production welding area were exposed to toxic concentrations of welding fumes and gases. No health hazards were identified in the plating room, heat treatment operation and grinding, sanding and abrasive cutoff area. Recommendations are made for improving the exhaust system to effectively remove welding fumes and gases.

The survey was prompted by a request from the employer regarding employee exposure to a variety of dusts, fumes and vapors. Measurements of workplace concentrations of airborne chemicals, evaluation of process operations and control measures, medical interviews, and a review of the pertinent literature led to the conclusion that exposures of employees to ammonia (7664417), beryllium (7440417), chromic-acid (7738945), lead (7439921), methyl- ethyl-ketone (78933), fumes, nitric-acid (7697372), nuisance dusts, oil mist, sodium-hydroxide (1310732), toluene-diisocyanate (1321386), 1,1,1-trichloroethane (71556), 1,1,2-trichloro-1,2,2- trifluoroethane (354585), welding fumes, mahogany wood dust and wood dust, and operations in the print shop, dark room and lapping were not toxic to employees. Employee exposure to free silica (7631869) at the vacu-blast operation was potentially toxic. Recommendations are made to reduce the dermatitis experienced by employees in some departments.

The request for the evaluation came from the Assistant Director of Concessions, United States Department of Interior, National Park Service, on behalf of an unspecified number of park rangers exposed to automobile exhaust emissions at the two entrance stations. The time weighted average (TWA) concentration of CO at the Front Royal Station was 29.28 parts per million (ppm), and 26.54ppm at the Panorama Station, compared with the OSHA standard of 50ppm. Breath analysis of rangers for CO and corresponding carboxyhemoglobin, revealed carboxyhemoglobin concentrations ranging from 1.9 to 6.1 percent, compared with the five percent limit recommended by NIOSH. SO2 concentrations ranged from 0.11 to 0.83 milligrams per cubic meter (mg/CuM), compared with the OSHA standard of 5mg/CuM. H2SO4 concentrations were in the range of 0.18 to 1.14mg/CuM, compared with the OSHA standard of 1mg/CuM. Lead exposures ranged from 1.81 to 5.62 micrograms per cubic meter, lower than the proposed OSHA standard of 0.1mg/CuM. The authors recommend positive pressure ventilation systems for the stations and shorter working hours in the stations for the rangers.

Specifically, possible exposures to sulfur-dioxide (7446095), lead (7439921), and carbon- monoxide (630080) emitted from cars being assisted at the entrance stations, which resemble toll booths, were to be evaluated. Of 11 analyses taken, five exceeded or were very near the 5 percent limit of carboxyhemoglobin recommended by NIOSH; five also ranged from half to over the recommended level of 1mg/m3 for sulfuric-acid (7664939). Sulfur-dioxide and lead exposures were all nonsignificant. All the rangers suffered excessive exposures to carbon-monoxide. The authors recommend that changes be made to reduce these exposures. The rangers could work in the booths for a shorter portion of the day, alternating with park rangers who perform other duties. Both booths could be operated at each station, thus reducing the amount to which each ranger was exposed. The installation of positive pressure ventilation should be the main approach and is likely to be the only one which will significantly alleviate the problem.

Primary products were caulking and roofing compounds. Possible exposures included benzene (71432), chlorobenzene (108907), dichlorobenzene (25321226), and vinyl-chloride (75014). Samples were analyzed for these chemicals along with total airborne particulate and lead (7439921) concentrations. A retrospective mortality study was made for the 12 year period starting in 1963. There was no evidence of exposure to potentially toxic levels of benzene or chlorobenzene when equipment was operating properly. However, at a time when equipment was malfunctioning, additive effects of benzene and chlorobenzene exceeded the permissible level determined by the American Conference of Governmental Industrial Hygienists additive effect method. No excessive exposures to vinyl- chloride or lead were detected. Mortality data for 39 current and exworkers showed no evidence of health hazards. The authors conclude that there is a potential for hazardous exposure during equipment malfunction. They recommend employee education in proper use of respiratory protective equipment, establishment of a proper decontamination method for air quality control, establishment of a maintenance program for machinery and ventilation systems, and use of local exhaust at the point of contaminant generation in the molding compound area.

Breathing zone samples were analyzed for iron-oxide (1309371) fumes, lead (7439921), and cadmium (7440439). Medical questionnaires were distributed. Blood and urine samples were randomly collected. The concentrations of toluene in the painting rooms ranged from 1 to 391 parts per million (ppm) which exceeded the OSHA criteria of 100ppm during an 8 hour exposure. Lead and cadmium samples were below detection limits. Iron-oxide fumes ranged from 0.2 to 13.3 milligrams per cubic meter (mg/m3); two out of ten samples grossly exceeded the American Conference of Governmental Industrial Hygienists criteria of 5.0mg/m3. Environmental values for isopropanol, MEK, lead, and iron-oxide fumes were below the criteria when measured 1 year later. Urine tests were in the normal range and only one worker had a blood lead content that was high. Complaints indicated burning, itching, or tearing of the eyes as the most common symptoms of exposure. Medical findings were consistent with overexposure due to toluene, MEK, and MIBK. Recommendations include proper use of spray paint booths, use of respirators in poorly ventilated paint facilities, preplacement and periodic medical examinations of all workers, a log of work performed on a shift basis, and engineering changes to eliminate the practice of hand dipping metal parts in solvents.

Fabrications operations include cutting, stamping, welding and surface coating prior to assembly. The survey was prompted by a request from the 19 affected employees of the company to evaluate exposure to arsenic (7440382) throughout the plant after one worker was treated for arsenic poisoning. Environmental sampling, review of biological tests obtained from one employee, and a review of the pertinent literature lead to the conclusion that the exposure of pressmen, die setters, utility men, welders, platers, painters and maintenance men to arsenic, lead (7439921), mercury (7439976), and bismuth (7440699) was not toxic at the concentrations measured. No jugement could be made as to the cause of localized skin pigmentation observed in one worker; however, it does not appear to be related to arsenic exposure at the work place. A potential problem was noted in conjunction with eating habits of some workers and the composition of the paint used on heavy equipment throughout the plant.

The concentrations of formaldehyde (50000) do not exceed the evaluation criteria, although evidence exists that irritant toxicity to this agent is present in the exposed workers. The levels of toluene (108883) encountered cannot account for infrequent nose and throat soreness elicited by 2 workers. Bronze alloy furnace tenders and pourers are frequently exposed to lead levels in excess of the recommended standards; the same is valid for casting chipping and grinding personnel, who also undergo excessive copper (7440508) dust exposure.
