Bags containing asbestos were fed onto a conveyor system and subjected to a fluffing operation to agitate the fibers. After mixing, the fiber was encapsulated and little asbestos dust was generated. Personal breathing samples were collected near the breathing zone of employees likely exposed to airborne asbestos fibers. The asbestos bag opener, the control panel operator, the forklift driver, and a dispensing line worker were monitored. Total fiber counts on the five analyzable samples ranged from 0.08 to 0.37 fibers per cubic centimeter of air. The asbestos bag opener and the forklift operator were exposed to concentrations above the OSHA limit of 0.2 fibers per cubic centimeter. The author recommends that asbestos be replaced by a less toxic substance. Engineering controls such as isolation, enclosure, and ventilation should be used to control exposure to asbestos if a suitable substitute cannot be found. Industrial type vacuum equipment should be installed for cleaning purposes. Respirators should be used during non routine operations.

An additional concern was the incidence of fungal sinusitis and cancer at MEB. Questionnaires were obtained from 406 of 690 current MEB employees. Nearly 60 percent reported discomfort believed to be work related. Windows in the building did not open and the heating, ventilation and air conditioning system was the primary source of outside air supply. Measured levels of airborne dust, gas and vapor concentration were below permissible exposure limits and exposure guidelines. Only one case of fungal sinusitis was confirmed. Mean airborne fungal concentration was 75 colony forming units per cubic meter. The authors conclude that the symptoms experienced resulted from substandard ventilation in conjunction with low level indoor pollutants such as tobacco smoke. Neither an increased prevalence of cancer nor a building related cancer risk appeared to exist. The authors recommendations include readjustment of the ventilation system to operate according to design specifications, routine maintenance and surveillance of the ventilation system, adoption and enforcement of a no smoking policy, institution of a more formal medical surveillance system, and rolling/changing of roll filters in the ventilation system when the system is turned off.

At this location in the factory, three employees are charged with weighing and loading a large variety of fragrances, flavorings, starch, and 50 to 100 pound bags of flour into one of three mixers. Considerable dust is generated during the loading and mixing tasks. At times, this dust level has been measured at 20 milligrams per cubic meter. When material was added to the mixers, employees wore a supplied air respirator. Workers did not always use the respirator during clean up operations. Catastrophic fixed airway disease developed in two workers who had no known personal risk factors prior to employment at the factory. The disease is suggestive of bronchiolitis obliterans or emphysema. The workers demonstrated symptoms of the disease within 5 to 6 months of beginning employment. Two other workers in the mixing room were not affected. No specific etiology of the illnesses was identified. The authors conclude that a short term exposure to a specific mix may have triggered the reaction and initiated the disease in these individuals. They recommend that when a specific etiology for a disease cannot be found, all airborne dust exposures should be controlled in the mixing room. In cases where engineering or ventilation changes alone may not be sufficient, protective equipment in the form of a respirator should be worn. This report also contains the walk through survey report made at the facility to study control technology employed in the manual transfer of chemical powders.

(SIC-3999), Boulder, Colorado, an evaluation of exposures to lead (7439921) in the copper and lead glazing art studio was carried out. Three workers were involved at the time, and the possibility of hiring more workers prompted the request. Breathing zone and general air samples were analyzed by NIOSH Method P and CAM 173, blood lead was measured by voltammetry, and free erythrocyte protoporphyrin was measured photofluorometrically. Average airborne lead concentration was 0.08mg/m3, and five of seven samples equaled or exceeded the OSHA time weighted average limit of 0.05mg/m3. Blood lead concentrations were 7, 16, and 33 micrograms/deciliter (microg/dl), which were all below the OSHA limit of 40microg/dl for returning to a job involving lead exposure. One free erythrocyte protoporphyrin sample was 59microg/dl, which was above the normal limit of 50microg/dl. Ventilation was found to be inadequate for removing airborne lead resulting from use of lead dust and furnaces. The author concludes that the high environmental lead levels present a health hazard, and recommends improved exhaust ventilation, continued use of ultra filter respiratory protection, and education of new employees on clean work habits.

Simplot Company (SIC- 2874), Helm, California, total nuisance dust air concentrations were measured during fertilizer, ammonium-sulfate (7783202) and ammonium- phosphate (7783280, 7722761), bagging and bulk loading. Four samples showed nuisance dust concentrations ranging from a no dust concentration to 0.38 milligrams per cubic meter (mg/m3), none of which exceeded the CAL-OSHA standard of 10.0mg/m3. At a follow-up survey, six environmental air samples collected ranged from 2.55 to 11.1 mg/m3, one of which exceeded the CAL-OSHA nuisance dust standard. The author concluded that a potential health hazard exists due to nuisance dusts. The greatest potential for exposure occurs when the front end loader operator quickly dumps the fertilizer from the loader onto the floor grating, creating a dust cloud. It was recommended that the front end loader should be reminded to slowly dump the fertilizer onto the floor grating to help control dust generation; that a method be devised to remind the operator to turn off the wax atomizer spray system to control dust exposure when the conveyor line is turned on to do bulk loading of fertilizer; that workers close the screen doors after inspecting or cleaning the screens; and employees who wear disposable respirators be qualitatively fit tested to assure a good face to piece seal.

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 evaluations were conducted in response to two separate requests concerning employee exposure to formaldehyde (50000) and phenol (108952) vapors during the assembly of brake pads in the Subassembly Department, and exposure to dusts during the grinding, cutting and drilling of engine parts at the Cam Line. Personal breathing samples for formaldehyde were below the analytical limit of detection 2 milligrams per sample. General air samples showed trace levels of phenol, 0.025 parts per million (ppm) and 0.042ppm. OSHA permissible exposure limit for phenol is 5ppm. Personal samples at the Cam Line showed time weighted average concentrations for total and respirable particulates ranging from to 0.43mg/m3, respectively. OSHA permissible exposure limit for respirable particulate is 15.0mg/m3. The author concluded that no hazard exists at this time. It is recommended that curing and gluing oven temperatures be below 550 degrees-F, increased efforts be made to alleviate dermatitis problems should they arise, employees be encouraged to avoid skin contact with lubricating fluids, good personal hygiene be encouraged, and incidences of carpal tunnel syndrome and other ergonomic hazards be investigated.

Air samples were collected and analyzed for total fiber count. Samples were also analyzed by transmission electron microscopy for fiber identification, gravimetrically for respirable dust exposure, and using X-ray diffraction for quartz (14808607) content. Medical questionnaires were completed by 73 of 100 insulators. Respirable dust concentrations ranged from 8.7 to 30 micrograms per cubic meter (microg/m3). Concentrations of total fibers less than 5 microns in length ranged from 0.0017 to 0.005 fibers per cubic centimeter. Asbestos (1332214) concentrations did not differ significantly from zero. Symptoms most frequently reported were sneezing, experienced by 81 percent of respondents, followed by runny nose, frequent colds, and skin irritation. Sixty three percent reported having some nose bleeds, consisting of spotting when blowing the nose, with an average frequency of two per week. The author concludes that employee symptoms are probably caused by the irritating properties of magnesium-silicate, portland cement (65997151), and fibrous glass, as well as poor work practices which resulted in direct contact and transfer of the irritating dusts. Rigorous attention to personal hygiene is recommended.

French Company (SIC-2099), Springfield, Missouri requested an evaluation of worker exposure to ethylene-oxide (75218) and methyl-bromide (74839). The facility employs 375 workers and was established exclusively for spice handling and manufacturing. Thirteen personal air samples for ethylene-oxide ranged in concentration from .01 to 1.07 parts per million (ppm). The three samples which exceeded the OSHA standard of 1ppm were from workers unloading sacks of sterilized spices from inside trucks. Twelve environmental air samples for ethylene-oxide ranged from less than .01 to 15ppm, with the highest being obtained from inside the trucks during unloading operations. No methyl- bromide was detected in personal samples on the packaging line and the two area samples on top of the tote bins in the fumigation room showed 12.5 and 45ppm. The author concludes that uncontrolled conditions which exist may result in exposure to the compounds; during this survey, the levels to which workers were exposed would not represent a health hazard. It is recommended that a means be devised to ventilate the trucks carrying spices during the trip from the contract sterilizer. Trucks should be monitored during unloading to be certain that levels of ethylene-oxide are not rising. The ventilation system in the fumigation room should be reviewed. The manner in which totes are treated with methyl-bromide should also be reconsidered.

An environmental survey was conducted in the Polyurethane Department and the Spiral Wind Department, and 62 workers took part in a medical survey. In the Polyurethane Department, 20 personal breathing zone full shift air samples for toluene-diisocyanate (584849) (TDI) ranged from 1 to 30 micrograms/cubic meter (microg/m3). Methylene-chloride (75092) ranged from 11 to 180mg/m3. Bromochloropropane was below the limits of detection. Medical examination revealed that two nonsmoking workers in the Polyurethane Department had an obstructive pulmonary function test pattern, which may be indicative of overexposure to toluene-diisocyanate. In the Spiral Wind Department, airborne total dust concentrations ranged from less than 0.1mg/m3 to 0.3mg/m3. In this area, toluene (108883) exposure levels of 22 and 13mg/m3 were found. The authors conclude that there may have been a hazard from methylene-chloride exposure in the Polyurethane Department. Overexposures were not found in the Spiral Wind Department, although at the time of the study, the workforce in the Spiral Wind Department had been reduced from 21 to three workers. The authors recommend changes in engineering, medical, educational and personal protection practices to reduce exposures.
