Workers at the facility produced lead alloys and lead tubing. The alloy shop and the oil press extrusion shop were located in separate areas of the facility. Personal protective equipment included respirators and work coveralls. A local physician provided blood analyses for lead exposure monitoring every 6 months or every month, depending on exposure levels. Personal breathing samples were collected for all the workers. Trace levels of several metals were found, but only lead levels exceeded allowable limits, ranging from 0.002 to weeks prior to the survey indicated levels ranging from 5 to 63 micrograms/10 grams whole blood. None of the workers experienced any health problems linked to lead exposure. Several areas which had been out of compliance with OSHA standards during an earlier investigation had been improved. The authors conclude that a potential health hazard existed from exposure to lead in the lead furnace areas. The authors recommend specific measures concerning air monitoring, respiratory protection, personal protective clothing, hygiene facilities and practices, medical monitoring, and ventilation.

The shop employees six workers involved in the cleaning and repairing of automobile and truck radiators. The 8 hour time weighted average lead (7439921) concentrations for the four mechanics were 220, 90, 50, and 30 micrograms per cubic meter (microg/m3). Three of these levels were at or above the OSHA 50microg/m3 permissible exposure limit. All six employees participated in a medical evaluation. The blood lead levels of the mechanics were 41, 33, 32, and 13 micrograms per deciliter (microg/dl). The blood lead levels of the two delivery personnel were 21 and 14microg/dl. One mechanic had a blood lead level over the 40microg/dl limit which requires that blood be tested every 2 months. None of the employees had elevated free erythrocyte protoporphyrin concentrations. None had any physical symptoms suggestive of lead intoxication. The authors conclude that a health hazard existed from overexposure to lead. The authors provide recommendations to prevent lead overexposures, and develop an environmental and medical program in compliance with the OSHA lead standard.

None of the employees had elevated free erythrocyte protoporphyrin concentrations or any physical symptoms suggestive of lead intoxication. The authors conclude that a potential health hazard existed from overexposures to lead. The authors recommend that activities required by the OSHA lead standard should be carried out to assist in eliminating this hazard. Local exhaust ventilation should be installed at the source of lead fume generation.

One mechanic had a blood lead level over the 40microg/dl limit requiring that blood tests be performed every 2 months and one had a level over 50microg/dl requiring his removal from the area where the airborne lead exceeded 30microg/m3. The two mechanics with elevated blood lead levels also had elevated free erythrocyte protoporphyrin levels (155 and 70microg/dl, respectively). None of the shop employees had any physical symptoms suggestive of lead intoxication. The authors conclude that a health hazard existed from overexposure to lead. The authors recommend that the provisions of the OSHA lead standard should be implemented to protect the workers.

Twenty workers had full shift air lead (7439921) levels ranging from less than 3 to 31 micrograms/cubic meter (microg/m3). All were below the OSHA action level of 30microg/m3 except one worker who was relining ladels with refractory material. Blood lead levels were below levels known to cause adverse health effects in adults. Levels for other metals were below allowable limits and no health hazard was found to exist. The authors conclude that a health hazard did not exist from exposure to lead. There was a potential cancer risk from exposure to components of welding fumes and melt shop dust. The authors recommend measures to reduce exposures to nickel (7440020), arsenic (7440382), and cadmium (7440439). These included periodic monitoring of airborne lead and the use of respiratory protective equipment.

The company manufactured glass panels and funnels used in the production of television picture tubes. The facility employed about 560 persons and operated 24 hours a day, 7 days a week, on a four shift schedule. Airborne concentrations of coal-tar-pitch volatiles (CTPV) ranged from nondetectable to 0.19mg/m3. Only one of the three general area air samples had a detectable concentration, recommended exposure limit of 0.1mg/m3 and one area sample exceeded the OSHA permissible exposure limit of 0.2mg/m3. Trace levels of four polynuclear aromatic hydrocarbons were detected. Lead (7439921) exposure was monitored for furnace operators, the ware handlers and the inspector/packers. The results ranged from nondetectable to 248 micrograms/cubic meter. Seven bulk settled dust samples were collected for asbestos (1332214) identification. The amounts of chrysotile (12001295) present ranged from 1 to 20%. The authors conclude that there was insufficient evidence to link the cancers and illnesses present in the work force with occupational exposures. Health hazards existed from exposure to coal-tar-pitch volatiles and lead among press operators and ware handlers, respectively. The chrysotile levels were high enough that abatement measures were warranted.

Each qualifying session of firing consisted of 60 rounds fired in 10 to 12 minutes. Personal breathing zone air samples were taken from three shooters and the range officer. Lead exposure concentrations measured were 2073, 1786, 172, and 142 micrograms of lead per cubic meter of air (microg/m3). Eight hour time weighted average concentrations were calculated to be 194, 167, 101, and 13microg/m3, respectively. The three shooters were therefore overexposed to lead. Bulk sampling of the sand from the bullet trap indicated it to be contaminated, containing 41% lead by weight. The authors concluded that a health hazard existed from exposure to lead. The authors recommended changes to improve the ventilation system. Following modification of the system, tests were again conducted and 11 of the 12 samples taken were below the limits of detection for the method used. The authors conclude that after modification, a hazard did not exist during qualifying sessions. The authors recommend specific measures to protect personnel from exposure to lead.

One stage in fire assay involved separating noble metals in ore samples from lead in a process called cupelation. An 8 hour time weighted average lead concentration of 170 micrograms/cubic meter of air (microg/m3) was noted for the personal breathing zone sample for the assayist, which exceeded the limit of 50microg/m3 recommended by OSHA. The actual exposure may have been less since the employee was wearing respiratory protection. The result of area air sample analysis indicated that no other metals were present in significant amounts when compared to their environmental criteria. A medical survey indicated that workers were experiencing increased frequencies and intensities of symptoms consistent with lead poisoning compared to nonassay laboratory workers. Blood lead levels were significantly higher in assay laboratory workers than in other workers; one of two assay laboratory workers had a blood lead level above 50 micrograms/deciliter. The authors conclude that a potential for lead exposure did exist at the time of the study and provide recommendations for lowering this exposure.

An 8 hour time weighted average (TWA) lead concentration of 850 micrograms/cubic meter of air (microg/m3) was noted in the personal breathing zone sample for the assayist, which was above the Mine Safety and Health Administration (MSHA) standard of 150microg/m3 at an 8 hour TWA. The employees in the assay laboratory reported an increased frequency and intensity of symptoms consistent with lead poisoning compared with nonassay laboratory employees. One of the four laboratory employees had a blood lead level of 50 micrograms/deciliter, which was above the OSHA action level of 30microg/m3. The mean free erythrocyte protoporphyrin levels were significantly higher among the assay laboratory employees compared to other employees. The authors conclude that a hazard did exist during the fire assay operations. Recommendations to management on measures to reduce this exposure are provided.
