The evaluation was requested by a vice president of the company. The factory employed about 160 workers. Ten to 16 workers were assigned to the compounding area where raw materials were batched, mixed, milled, and calendered. Total dust particulates ranged from 0.03 to 6.9 milligrams per cubic meter (mg/CuM), one lead sample was 9.7 micrograms per cubic meter as an 8-hour time weighted average (TWA), antimony concentrations ranged from 0.01 to 0.15mg/CuM and carbon- black concentrations ranged from 0.11 to 2.59mg/CuM. Dust particulates, lead, antimony and carbon-black OSHA criteria standards were 10mg/CuM, 30 micrograms/CuM meter for an 8 hour (TWA), 0.5mg/CuM and 3.5mg/CuM for an 8 hour TWA, respectively. The author concludes that there were no hazardous exposures to dust containing carbon-black, lead or antimony under existing conditions. He recommends that work practices be closely monitored to minimize exposure to lead and antimony and that their suggestions for further reducing exposures be implemented.

(SIC-3523) in Fargo, North Dakota on May 15 to 17, 1979. The survey was requested by the International Association of Machinists' and Aerospace Workers Local 2525 on behalf of an unspecified number of workers. Atmospheric samples were collected and analyzed, and day shift workers were given medical studies consisting of questionnaires on general health and specific symptoms, blood sample collection and pulmonary function testing. Atmospheric concentrations of lead, ferric-oxide, manganese, chromium and copper ranged from none detected (ND) to 1.90, ND to 27.7, ND to 1.52, ND to 0.34, and ND to 0.01 milligrams per cubic meter (mg/CuM) respectively. Corresponding OSHA, NIOSH, or American Conference of Governmental Industrial Hygienists (ACGIH) 8 hour time weighted permissible exposure limits (PEL) are 0.05, 5.0, 1.0, 0.025, and 0.2 mg/CuM, respectively. Atmospheric concentrations of xylene, toluene, MEK, and 1,1,1-trichloroethylene ranged from ND to 72, ND to 103, ND, and ND to 342mg/CuM, respectively, compared with OSHA, NIOSH, or ACGIH PELs of 435, 375, 590 and 1900mg/CuM, respectively. The author concludes that overexposure to lead, ferric-oxide, and manganese did exist at this facility and recommends better hygiene practices, improved ventilation, and regular medical testing.

A representative of the Oil Chemical Atomic Workers, Local Union 2-230, requested the evaluation on behalf of six workers in the welding shop. Iron-oxide concentrations ranged from 0.1 to 1.3 milligram per cubic meter (mg/cu m compared with the recommended threshold limit value (TLV) of 5.0 mg/cu m recommend by the American Conference of Government Industrial Hygienists (ACGIH). Manganese ranged from less than detectable to 0.05 mg/cu m compared with the ACGIH permissible exposure limit of 5.0 mg/cu m. Aluminum ranged from less than detectable to 0.04mg/cu m, well below the ACGIH permissible exposure limit of 5.0mg/cu m). Copper ranged from less than detectable to 0.01mg/cu m, below the OSHA standard 0.1mg/cu m). Nickel ranged from less than detectable to 0.01mg/cu m; the OSHA standard is 1.0mg/cu m. Lead and fluoride were less than detectable. The medical questionnaire failed to identify any work- related employee health problems. The author concludes that no exposure hazards exist at this facility, but recommends that all mechanical exhaust systems be well maintained, and that good personal hygiene and work practices be followed by all employees.

As this facility had been closed almost 2 years earlier, sampling for lead (7439921) concentrations was not possible. The evaluation was needed so that the facility could be reopened for handgun qualifying of U.S. Marshals. The range was 108 feet long, 12 feet wide and 9 feet high with three firing booths. The ventilation system supplied about 1300 cubic feet of air per minute (cfm) and exhausted 3700cfm. Air entered through 12 ceiling diffusers and exited through three ceiling diffusers, one above each shooting station. The range was under negative pressure with regard to the rest of the building. Ventilation was acceptable at the shooting stations, but the air became stagnant further down range. The air supply to the range officer needed to be redesigned to avoid drafts and to increase the efficiency of lead dust removal. The author recommends modifications which would render this facility operational. The sand pit at the end of the range used to trap spent bullets should be replaced with a water trap. The author recommends that reflecting walls be covered with high efficiency sound absorbing material and that the back sides of the trap plates be covered with an epoxy resin to reduce noise levels.

Personal and general area air samples were collected during two qualifications firing periods. A total of 640 and 60 rounds were fired from handguns and from a shotgun, respectively. Four shooters and a Rangemaster participated. Samples were analyzed using atomic absorption spectrophotometry. Air velocity was measured to determine the adequacy of the ventilation. Average Pb concentrations for handgun firing ranged from 390 to 902 micrograms per cubic meter, with an 8 hour time weighted average (TWA) of 57 to 115 micrograms per cubic meter. All personal air samples, except the Rangemaster's, were in excess of the recommended OSHA exposure limit of 50 micrograms per cubic meter. No Pb was detected from shotgun firing. Average air flow through the shooting stalls ranged from 5 to 30 feet per minute (FPM), as compared to the recommended 50FPM. The authors recommend that 20 to 40 percent of the air be exhausted from ceiling height 10 to 20 feet down range of the stalls, and 60 to 80 percent be exhausted at the end of the range behind the bullet trap. Exhaust air should exceed supply air to create a negative pressure system and avoid contamination of neighboring areas.

The evaluation request was by the United Steelworkers of America, Local 2697 on behalf of 34 welders to evaluate a high rate of cardiovascular disease among workers. Concentrations of total chromium, hexavalent chromium and particulate fluoride were 0.02, 0.006, and 0.003 milligrams per cubic meter (mg/CuM), respectively; and their corresponding OSHA permissible exposure concentrations were 1.0, 1.0 and 2.5mg/CuM. Concentrations of iron-oxide, manganese, lead, and welding fumes ranged from 0.1 to 2.9, 0.004 to 0.19, 0.01 to 0.57 and 0.59 to 9.6mg/CuM, respectively, and their corresponding OSHA permissible exposure concentrations were 10.0, 5.0, 0.05, and 5.0mg/CuM. Gaseous fluorides, nickel, molybdenum and vanadium were not detected. Concentrations of carbon-monoxide ranged from less than 2 to 73.8 parts per million (ppm), exceeding the OSHA standard of 50ppm. The medical survey indicated an excess incidence of cardiovascular disease and increased respiratory symptoms. Blood lead and free erythrocyte protoporphyrin results were normal. The authors conclude that a health hazard due to overexposure to lead, carbon-monoxide and welding fumes and an excess of cardiovascular disease and respiratory symptoms exists. They recommend measures for the protection of workers and the reduction of hazards.

(SIC-3361), in Englewood, Colorado. The evaluation request to identify any potentially toxic workplace exposures for approximately 50 employees came from an employer representative. Concentration of inorganic lead (7439921) ranged from 0.03 to 3.2 milligrams per cubic meter (mg/cum) and exceeded the OSHA standard of 0.05mg/cum in 44 percent of the samples. Crystalline silica (14808607) concentrations exceeded the OSHA standard of 0.29mg/cum in 77 percent of the samples. All other sample concentrations were below criteria. Blood lead concentrations exceeded the OSHA standard of 40 micrograms per 100 grams of whole blood in 81 percent of the workers, and 72 percent had free erythrocyte protoporphyrin determinations above the normal range of 356 to 662 micrograms per liter of red blood cells. The investigator concludes that workers were exposed to hazardous concentrations of inorganic lead and crystalline silica, and other toxic exposures could occur if production conditions change without corresponding ventilation improvements. The use of respirators, protective hearing devices and clothing; improvements of workplace hygiene and ventilation systems; and periodic medical surveillance until all exposures are below criteria are recommended.

The evaluation was requested by the Oil, Chemical, and Atomic Workers International Union Local 8-621, for the 15 potentially exposed employees. The benzene (71432) soluble fraction of polycyclic aromatic hydrocarbons (PPAH) measured 0.43 milligrams per cubic meter (mg/cu m) and exceeded the OSHA recommended exposure limit of 0.20mg/cu m in one of four sampling periods. Total dust particulates ranged from 1.1 to 8.5mg/cu m, lead (7439921) was undetectable, and sulfur dioxide (7446095) gas measured 3.1 micrograms/cu m. All were below their respective recommended limits of 15mg/cu m, 50 mg/cu m, and 13mg/cu m. Medical reports of acute, intermittent irritation of the eyes and mucous membranes of the upper respiratory tract, dry skin, occasional headache, sinus congestion, and wheezing with exertion were associated with increased heat and with the burning of certain products that probably contained sulfur dioxide. The authors recommend periodic vacuum cleaning of the burner house, periodic maintenance of the burner and ducts to seal leaks; a program of environmental sampling, preplacement and periodic medical examinations for exposed workers, maintaining medical records on all employees exposed for 1 or more years to sulfur dioxide, and a review of the value of the current preemployment practice of routinely recording lower back radiographs.

The survey was requested by the Office of Administration, Department of Transportation, Government of the District of Columbia, to evaluate exposures of approximately 18 inspectors during routine vehicle inspections. All asbestos, hydrogen-sulfide, and sulfur-dioxide concentrations were below detectable limits. Carbon-monoxide and lead concentrations were below the OSHA standards of 50 parts per million and 20 milligrams per cubic meter, respectively, for an 8 hour time weighted average (TWA) at both facilities. Exposures were affected by weather conditions and the number of vehicles tested daily. The investigator concludes that fluctuating concentrations hampered the evaluation of long term health effects. There was a potential for high exposures to lead and carbon monoxide, especially at the busier Southwest station. Local and increased ventilation at the first and last inspection stops, preemployment cardiovascular medical examinations, personnel rotation, air conditioned squad rooms, vehicle number limitations, daily vacuuming, use of gloves, hand washing, scheduled inspections, and education concerning the hazards of smoking are recommended by the author.

An authorized representative of approximately 80 employees from Local Number 13, International Printing and Graphic Communication Union and Newspaper Printing and Graphic Communication requested the evaluation to determine worker exposures to paper dust, oil mist, and inorganic lead (7439921) in the press and reelroom. Forty three employees completed medical questionnaires and 18 received blood lead tests. All blood samples for lead were in the normal range (40 micrograms of lead per 100 grams of blood). All environmental samples were at or below the OSHA standard for lead of 0.05 milligrams per cubic meter (mg/cum), oil mist (5mg/cum), and total particulates (15mg/cum). Noise levels were between 100 and 105 decibels throughout the pressroom. The authors conclude that a health hazard did not exist at the time of the survey, but there is evidence of a potential noise hazard. Recommendations resulting from the survey include institution of a lead monitoring program, installation of sound absorbing and baffling devices in the pressroom, provision of audiometric testing and preemployment physical examinations, and development of health and safety programs. Ventilation systems should be serviced regularly, and worker and workplace hygiene practices should be improved.
