The 8 hour time weighted average (TWA) CO levels ranged from 64 to 74 parts per million (ppm); the OSHA 8 hour TWA permissible exposure limit is 50ppm. The CO levels resulted from the use of six propane forklift trucks and an inadequate distribution of airflow. Airborne CO concentrations behind the forklifts were as high as 350ppm. After tuning the trucks, the CO level was significantly reduced. Airborne lead concentrations for four personal and three area samples were less than 2 micrograms/cubic meter. Five of six employees interviewed reported headache, and eye and throat irritation, attributed to fumes from the propane forklift trucks. The four employees on the tin and lead line reported no health problems related to the job. The authors conclude that overexposure to CO occurred in the shipping and warehouse area. A health hazard from exposure to lead did not exist at the time of the evaluation. Recommendations include modifying the ventilation system; increasing the air supply system to balance air flow in the building; direct supply air at points of heavy forklift use; install overhead air circulating fans; and use direct reading monitoring equipment to measure CO.

Medical surveys were conducted and environmental air samples collected. Additional specific substances investigated included titanium (7440326), nickel (7440020), chromium (7440473), iron oxide (1332372), cobalt (7440484), vanadium (7440622), aluminum (7429905), cutting fluids, and 1,1,1-trichloroethane (71556). No evidence of excess respiratory disease was found among 45 grinders. A substantial number of employees complained of irritant symptoms attributed to brief exposures to high concentrations of the grinding dust. No evidence of skin problems related to coolant exposures was noted. Concentrations of total particulates were below the OSHA standard of 15 milligrams per cubic meter (mg/m3) as an 8 hour time weighted average (TWA). Nickel was detected in five of six personal samples at TWA concentrations ranging from 0.002 to 0.056 mg/m3. The authors conclude that instances involving the grinding of large forgings and forgings containing nickel present a potential health hazard if not properly controlled. It is recommended that nickel exposure be reduced to the lowest feasible level. Employees should position their work so that dust generated is effectively captured by the grinding hood, in some cases using a moveable hood, or periodically repositioning a part.

The environmental evaluation consisted of measuring breathing zone and general room air concentrations of lead, copper (7440508), and antimony (7440360). Copper and antimony were present in trace quantities and did not pose a health hazard. Four of the eight lead samples exceeded the NIOSH recommended exposure limit of 0.05 micrograms/cubic meter (mg/m3). The average of all eight samples was 0.12 mg/m3. Lead exposure levels ranged from 0.02 to 0.38 mg/m3. Medical monitoring and evaluation consisted of blood lead and free erythrocyte protoporphryin (FEP) determinations in all four radiator shop workers and the weekend janitor. Of the five workers tested, two were within the normal unexposed range. The other three had elevated FEP's and two had blood lead levels over 40 micrograms/deciliter (microg/dl). The author concludes that a health hazard existed from overexposure to lead during the cleaning and repair of radiators. The author recommends measures to reduce exposure to lead, including: installation of local exhaust ventilation; frequent blood lead analysis for all workers; and removal of workers with a blood lead concentration of 50 microg/dl or more from further lead exposure until the blood lead concentration is below 40 microg/dl.

The evaluation was requested by the management because of concern for the workers' health. Medical questionnaires were administered to eight workers in the leaded crystal grinding room. Blood lead and free erythrocyte protoporphyrin (FEP) concentrations were measured in the grinding room workers and in three comparisons. All exposures were below the relevant standards except for lead. Five of six air samples exceeded the OSHA standard of 0.005 milligram per cubic meter (mg/m3) for lead. The lead concentrations ranged from 0.3 to 0.08mg/m3. The mean blood lead concentration in grinding room workers was 29.1 micrograms per deciliter (microg/dl); values in comparisons averaged 7.2microg/dl. No excessive lead concentrations (over 40microg/dl) were found. No evidence of lead toxicity was found. FEP concentrations averaged 31.4microg/dl in the exposed workers and 21.6microg/dl in the comparisons. The authors conclude that a health hazard due to overexposure to lead exists in the grinding department. Recommendations include improving work practices, prohibiting dry grinding or polishing of leaded glass, and installing down draft ventilation.

The surveys were requested by the union local because of irritative symptoms and respiratory problems reported by employees exposed to epoxy resin compounds and impregnated materials. Medical questionnaires were administered to 51 employees in the hand taping and pole winding departments and 57 comparisons. Formaldehyde, acetaldehyde, and lead were the only contaminants detected. All concentrations were below their OSHA standards. Skin rash and irritation, eye irritation, and throat irritation were the most frequently reported symptoms. Fifty six percent of the exposed workers had evidence of carpal tunnel syndrome versus 7 percent of the comparisons. The authors conclude that mucous membrane irritation and dermatitis are common among workers exposed to epoxy resins. A high prevalence of carpal tunnel syndrome was also found. Recommendations include reducing formaldehyde concentrations, using personal protective equipment and barrier creams, and maintaining proper work practices and good personal hygiene to minimize contact with epoxy resin materials.

The evaluation was requested because of two arsenic poisoning cases that occurred in department 48. All department 48 employees were surveyed by questionnaire. Urine arsenic concentrations were measured. Only 1 of 68 air samples contained arsenic, 3.3 micrograms per cubic meter (microg/m3). The OSHA standard for arsenic is 10microg/m3. Arsenic was not detected in any bulk samples. Nickel (7440020) and barium (7440393) were detected at concentrations of 17.7 to 1,280 and 502 to 678microg/m3, respectively. The OSHA standard for either metal is 500microg/m3. One copper (7440508) sample, 5,700microg/m3, exceeded the OSHA standard of 1,000microg/m3. Carbon-monoxide and arsine concentrations were below their relevant standards. No workers had symptoms of arsenic poisoning. Urine arsenic concentrations were within normal limits. The authors conclude that employees are not being exposed to detectable amounts of arsenic. The source of the arsenic poisoning cannot be determined. Employees are overexposed to nickel, barium, and copper. Recommendations include improving employee training and education regarding respiratory protection and reducing employee exposures to nickel and barium.

The evaluation was requested by the union to assess exposures to lead (7439921) and other substances. Concern was expressed about apparent physiological discrepancies between blood lead and zinc- protoporphyrin (ZPP) concentrations in certain workers. Company lead monitoring and blood lead/ZPP data was reviewed. Urine samples were obtained from 49 workers and analyzed for arsenic. The company respirator program was reviewed. Eleven percent of 675 lead breathing zone samples exceeded the OSHA standard of 50 micrograms per cubic meter. Highest exposures were among janitor and maintenance workers. Arsenic, stibine, and antimony exposures were below the OSHA standards. Sulfuric-acid was not detected. No pattern of medically unexplained discrepancies between blood lead and ZPP concentrations was detected. Urine arsenic concentrations were within the normal range. Improper use of respirators was observed. The authors conclude that there is no definite pattern in the company blood lead/ZPP data. Maintenance and janitorial personnel have the greatest potential for lead exposure. Recommendations include keeping worker blood ZPP concentrations from rising excessively and improving the respirator program.

The survey was requested by the local union to evaluate potential hazards at the facility. Biological monitoring for blood lead, free erythrocyte protoporphyrin, and zinc-protoporphyrin in five lead exposed individuals was conducted. Medical questionnaires were given to 16 ECA and five lead exposed workers. ECA at a concentration of 4.6 milligrams per cubic meter was found in the work areas. There is no Federal standard for ECA. Concentrations of the other substances were below the limits of detection. All biological monitoring results were within normal limits. ECA exposed workers had a higher incidence of upper respiratory symptoms such as stuffy nose and irritated or sore throat than lead exposed workers. Lead workers had a higher incidence of skin rashes than ECA exposed workers. The authors note that the use of ECA has been discontinued at the facility. The data suggest that exposure to ECA causes sensitization and allergic reactions. Improved local exhaust ventilation is recommended.

The evaluation was requested by the facility to assess lead exposures during cutting and rivetting operations aboard a lead painted, iron hulled ship. Blood lead and erythrocyte protoporphyrin (EP) concentrations were determined in 10 shipfitters. Noise exposure measurements were made. Breathing zone lead concentrations averaged 257 micrograms per cubic meter (microg/m3). The OSHA standard for lead is 50microg/m3. Two short term samples taken while the exhaust ventilation was temporarily disconnected contained 375 and 718microg/m3 lead. Blood lead concentrations averaged 37.8microg/deciliter (dl). Smoking shipfitters had higher blood lead concentrations than nonsmokers, 47microg/dl versus 32microg/dl, respectively. Four shipfitters had EP concentrations above the adult normal upper limit of 50microg/dl. No cases of symptomatic lead poisoning were noted. Noise levels adjacent to the rivetting averaged 121 A-weighted decibels (dBA). The OSHA standard for noise is 90dBA. The authors conclude that shipfitters working aboard ship are overexposed to lead and noise. Recommendations include substituting lead based paint with less toxic materials if feasible, avoiding the use of lead/based putty, and establishing a hearing conservation program.
