Environmental samples were collected for analysis, and employees were interviewed and given physical evidence of occupational asthma due to western and red cedar wood dust exposure; the average dust concentration in 85 breathing zone samples was 4.72 milligrams per cubic meter (mg/cu m). Among new planer workers, 3 of 58 had occupational asthma due to exposures to Douglas fir and hemlock wood dusts, and sodium pentachlorophenate (131522). Average dust exposure for these workers was 1.28 mg/cu m. For old planer, bark and pres-tock workers, hazardous exposures to Douglas fir and hemlock, Douglas fir and alder bark, and alder wood dusts, respectively, were identified. No toxic exposures were found for workers in the presto-log, plywood or resin areas. The author suggests that all workers receive preplacement and periodic medical evaluations including pulmonary function tests; individual medical records should be maintained for up to 30 years; and workers should be educated concerning the hazards, symptoms and proper safety precautions associated with wood dust exposure. Exposures to Western red cedar dust should not exceed 2.5mg/cu m, and exposures to alder, fir and hemlock dusts should be maintained below 50mg/cu m. Regular air sampling should be performed. Specific work practices should be established for Shake mill workers, and ventilation systems in all areas should be improved.

The survey was prompted by a request from an authorized representative of the about 200 affected employees regarding exposure to solvents. Environmental air samples, employee interviews, evaluation of ventilation systems and available toxicity information lead to the conclusion that exposures to monochlorobenzene (108907), isopropyl-alcohol (67630), methyl- ethyl-ketone (78933), toluene (108883), trichloroethylene (79016), sodium-hydroxide (1310732), phosgene (75445), zinc-oxide, cadmium (7440439), fluorides, hydrochloric-acid (7647010), and oil mist did not pose a health hazard at the concentrations measured at the time of evaluation. It is felt that the cause of the problems (such as nausea, dizziness, headaches, breathing difficulties, nose bleeds, etc.) at Airtex is a multifactorial one and involves an inefficient ventilation system which combines with the employees lack of information regarding the materials they use to cause fear and anxiety, and subsequent appearance of the types of problems reported.

An authorized employee representative requested the survey because the workers were complaining of headaches in certain areas of the facility. Environmental air sampling, confidential interview of seven of the 50 affected employees, evaluation of work procedures, and available toxicity information revealed that employee exposures at the burning table in the weld shop to total dust, iron-oxide (1317619), and manganese (7439965) did not constitute a health hazard, although during certain particular operations adequate ventilation should be provided. Employee exposure to total dust and n-butyl-glycidyl- ether (2426086) from an epoxy resin in the Bluecoat Spray Booth did not constitute a health hazard during the survey, although the workes should wear hand protective equipment to guard against dermatitis. In the Scotchcast Room of the Coil Department, ventilation was sufficient and employees wore skin protection, to the effect that a health hazard is not judged to exist there. For safety reasons, recommendations are made to modify the spray painting process.

An authorized representative of the employees requested the investigation in order to determine whether any substances normally found in the work areas had potentially toxic effects in the prevailing concentrations. The employee exposure to hexavalent chromium, as measured during the survey, did constitute a potential health hazard, both samples taken exceeding the OSHA ceiling standards of 100 micrograms of hexavalent chromium per cubic meter of air for chromic-acid (7738945) and chromates, as well as the NIOSH recommended ceiling of 50 micrograms per cubic meter for noncarcinogenic hexavalent chromium. Neither sample exceeded the recommended standard of 25 micrograms per cubic meter of breathing zone. The interview of one "affected" employee failed to reveal any health complaints. Recommended engineering controls to eliminate the potential health hazard include capture velocities of 100 to 200 feet per minute to control the dust release, a lateral local exhaust system around the rim of the material addition porthole, and improved respiratory protection program. A medical surveillance program that will allow the monitoring of chronic diseases, especially cancer, is also recommended.

The survey was prompted by a request from an authorized representative of the 6 affected employees regarding potential exposures associated to wood pattern making. Analysis of breathing zone air samples revealed that the concentrations of methyl-ethyl-ketone (78933), isopropanol (67630) and acetone (67641) were below the most recent evaluation criteria. The nonallergenic wood dust evaluation criteria was exceeded in 1 of 6 samples. One of the workers complained of nasal congestion and an allergic reaction to mahogany dust. Dermatitis was identified in another worker. The results show that a health hazard existed at the time of the survey. Recommendations are made for improved ventilation, use of respirators and barrier cream, and other safety and sanitary measures.

The evaluation was requested by the company owner on behalf of an unspecified number of workers. Samples were below OSHA standards of 50 parts per million (ppm) for cyclohexane (110827), 500ppm for petroleum naphthas, and 10ppm for benzene (71432). No PCBs were detected in the ink used by the printer, and atmospheric PCB concentrations were 0.1 milligrams per cubic meter (mg/cu m), well below the OSHA standards of 1.0 and evaluation criteria. Spray powder used in the facility contained 1 percent fibrous asbestos (1332214). About 10 percent of the powder contained minerals similar to asbestos. The author recommends that a local ventilation system be used on the offset printer to minimize the release of dust, or that a substitute powder without asbestos be used.

The evaluation was prompted by a request from an authorized employee representative regarding the exposure of approximately 50 affected employees to various toxic dusts and fumes. Environmental surveys revealed that employees working in and around the coater line for roofing shingles were exposed to excessive concentration of limestone (1317653) and other nuisance dusts, while those employed in the slate operation were exposed to potentially toxic concentrations of a dust which contain crystalline silica (7631869). Exposure to benzo(a)pyrene (50328) other polynuclear aromatics, alpha-naphthylamine (134327), beta-naphthylamine (91598), aliphatic hydrocarbons, benzene (71432) and other aromatic hydrocarbons were not toxic. Exposure to asphalt fumes could not be adequately determined with the current sampling and analytical methods. There were only signs of irritation from exposure to dust and fumes among the 18 employees interviewed.
