Air and dust samples were collected and analyzed for trace metal content, temperature, relative humidity, and carbon-dioxide levels; the presence of EMFs and ionizing radiation was evaluated as well. In addition employees were given medical evaluations. All EMF measurements were within the American Conference of Governmental Industrial Hygienists occupational exposure standards. Adequate ventilation and very low levels of chemical exposures were seen. Humidity exceeded recommended levels in several areas. Radioactive vacuum tubes had previously been in widespread use at this facility. The authors conclude that exposures to trace levels of chemical contaminants should not be in excess of occupational standards. Electrical shock potential existed. Electric and magnetic fields did not exceed occupational standards. The role of ionizing radiation from vacuum tubes previously in use must be considered in any study of cancer among telephone company central office employees.

A private physician had reported that one of his patients seemed to have severe pneumoconiosis, probably silicosis. This patient had been a railroad maintenance of way employee for the company for about 20 years as a track laborer. Environmental sampling was conducted during track maintenance activities by Timber and Surfacing Gangs at three sites. Of the 50 personal breathing zone and 21 area samples collected for respirable dust and crystalline silica, 27 of the personal and ten of the area samples equalled or exceeded the NIOSH recommended limit for respirable quartz of 0.05mg/m3. A medical survey of 32 track maintenance workers found no evidence of pneumoconiosis or adverse respiratory health effects. The overall prevalence of chronic cough was 31% and for chronic phlegm and shortness of breath, 25% each. The authors conclude that Timber and Surfacing Gang workers were being overexposed to crystalline silica. There was a potential for excessive crystalline silica exposure for track maintenance workers. The authors recommend measures to reduce exposure and for medical surveillance.

The pilot program involved testing the three methods in unoccupied buildings contaminated with deteriorated lead (7439921) based paint. A visit was made to the site to observe work practices, and conduct air, surface, and bulk sampling for lead. The three cleaning methods included dry scraping followed by broom sweeping, wet scraping followed by high efficiency particulate air (HEPA) filtered vacuuming, and wet scraping followed by HEPA vacuuming with a HEPA filtered air filtration device placed in the room to exhaust room air to the outside. Six workers cleaned 18 rooms in 1 day. Sampling for lead was conducted before, during and after cleaning. The authors conclude that workers were potentially overexposed to lead during the three methods. The wet HEPA method was the best for controlling lead exposures. Even using this method, lead exposures during cleaning reached 50 micrograms/cubic meter. The cleaning effectiveness of the three methods was not significantly different. The authors recommend that the contractor furnish workers with NIOSH approved HEPA filter respirators, protective clothing, a clean change area, handwashing facilities, and job specific hazard training.

The request concerned exposure to chemicals and starch dust used at the site, and respiratory symptoms experienced by the workers. The company manufactured printed cartons for consumer goods, employing about 200 persons over three shifts. Workers reported symptoms including dry or irritated eyes, stuffy nose, sinus congestion, dry or irritated throat, cough and dry skin. Air sampling indicated that individual chemical concentrations were significantly below the allowed limits. However, there was the potential for over exposure to organic solvents in the rotogravure department on days when the press persons spent a major portion of the workshift in this room. Several safety hazards were identified, including inadequate eye and skin protection, and failure to meet the OSHA requirements for respiratory protection and hazard communication programs. The authors conclude that workers were exposed to potentially hazardous concentrations of organic solvents in the rotogravure department. The authors recommend specific measures to reduce worker exposures.

The Department employed a staff of approximately 17 officers. Each month the firing range was used by four or five officers for 1 to 2 hours. The firing range occupied 2,500 square feet of the lower level of the building. The personal breathing zone (PBZ) measurements for lead exposure ranged from 36 to 48 micrograms of lead per cubic meter (microg/m3), based on the actual sampling time of 72 minutes. PBZ measurements for three officers ranged from 5 to 7microg/m3. All tests indicated the lead exposure levels were below the permissible limits. Thirteen general area air samples ranged from none detected to 845microg/m3. Peak sound pressure levels measured were as high as 160 decibels (dB), which did exceed the OSHA peak exposure criteria of 140dB. The authors conclude that there were no overexposures to airborne lead at the time of the evaluation. The authors recommend that personal hygiene practices be improved, that the firing range be properly maintained, and that hearing protection devices be maintained in good working order.

Handicapped individuals were employed at the woodshop manufacturing wood surveyor's stakes. Short term wood dust exposures ranged from 0.2 to 4.1mg/m3. The calculated time weighted average exposures were all below the OSHA and NIOSH exposure limits. The highest exposures from normal operations were seen from workers on the two table saws. The highest consistent task samples were found during clean up operations. Workers used brooms to dry sweep the floors and brush off machine surfaces. Personal noise dosimetry equipment indicated that average exposures over several time periods ranged from 79.8 to 93 decibels-A. The table saw operators had the highest general exposures, with equivalent exposures in the 85 to 93 decibel-A range. A partial hearing conservation program was in effect. The author concludes that a potential health hazard existed from overexposure to noise. The author recommends that a complete hearing conservation program be established.

The facility was a gray and ductile iron foundry. An electric induction and two holding furnaces were used to produce molten iron. No local exhaust hoods or air pollution control devices for the induction furnaces were in place. Four coremaking processes were used: hot shell, oil baked, cold box, and no bake. An industrial hygiene survey was conducted and included personal breathing zone and area air sampling, work practice evaluation, engineering control measures, and noise exposure assessment. The author concludes that workers were overexposed to respirable silica (14808607), lead (7439921) and noise. Carbon- monoxide (630080), chrysotile (12001295) and benzene (71432) exposures constituted a potential health hazard to employees in the coremaking, molding, pouring, cleaning and shakeout areas. The author recommended measures for reducing exposures and improving the use of respiratory protective devices.

Personal breathing zone air concentrations of respirable silica (14808607) ranged from 163 to 19,870 micrograms per cubic meter (microg/m3). All the 24 samples taken exceeded the NIOSH Recommended Exposure Limit (REL) of 50microg/m3. Twenty one samples contained cristobalite (14464461). Of the 16 iron exposures measured for the chipper/grinders, 12 exceeded the REL of 5,000microg/m3. Several nickel (7440020) concentrations exceeded the REL of 15microg/m3. Grinders were overexposed to noise. A paint dip tank area sample exceeded the 100 parts per million OSHA standard for xylene (1330207). Exposures to benzene (71432), ethyl-benzene (100414), toluene (108883) aluminum (7429905), chromium (7440473), copper (7440508), lead (7439921), magnesium (7439954), manganese (7439965) and zinc (7440666) did not exceed recommended limits. The authors conclude that workers were overexposed to respirable silica, cristobalite, iron, nickel, and noise; there was a potential health hazard from xylene. The authors recommend that engineering controls, use of personal protective equipment, and work practices be improved.

Complaints included breathing problems, itching, headaches, coughing, congestion, fiberglass from ceiling panels, and paper dust. The site was formerly a warehouse which was converted to office space. Five general area, full shift air samples were collected for total dust concentrations. The eight hour time weighted average results ranged from not detectable to 0.21mg/m3. Ozone (10028156) concentrations were equal to or greater than the NIOSH Recommended Exposure Limit (REL) of 0.1 parts per million (ppm) at microfiche reader printer exhaust ports. Carbon-dioxide (124389) levels in the building ranged from 425ppm to 875ppm. Temperature ranged from 72.0 to 80.0 degrees-F. Relative humidity indoors ranged from 48.4 to 64.4%. The most common symptoms reported by the workers were mucous membrane irritation, fatigue or sleepiness, and headache. The authors conclude that clear evidence was not found to explain all of the symptoms reported. Respiratory symptoms may be explained by ozone levels near the microfilm reader printers. Psychosocial conditions may have been contributory. The authors recommend that maintenance of the air handling system be improved.

The product was a freeze dried preparation of an endotoxin producing Gram negative bacteria, Pseudomonas-syringae. Snowmaking was done at the Red River Ski Area only during the night, and never when skiers were present. Samples were collected over 3 days to assess occupational exposures to airborne dusts, viable Gram negative bacteria, and endotoxins. Viable P-syringae were not identified in any air, snow or water samples. Endotoxins were detected in snow samples, samples of snowmaking water, and in airborne dust samples. Personal exposures to endotoxins among workers directly involved in snowmaking ranged from 1 endotoxin unit (EU) per cubic meter (m3) to 92EU/m3. There were no occupational standards for endotoxin exposure. The author concludes that workers were exposed to endotoxins during snowmaking. The mean exposures in the high exposure category were below estimated human threshold levels. No significant respiratory problems were reported by the workers filling out a questionnaire.
