The request came from an employee representative to determine if there was a health hazard from asbestos (1332214) exposure during the reconditioning of truck brakes and clutches. Airborne concentrations of asbestos, sodium-hydroxide (1310732), total welding fumes, nickel (7440020), manganese (7439965), copper (7440508), and noise levels were determined. Of two personal and three area samples taken for asbestos, one was above the NIOSH criteria of 0.10 fibers per cubic centimeter greater than 5 microns in length. Samples of all other chemicals and measures of noise levels were below NIOSH criteria values. An exhaust system was developed to remove the major source of asbestos exposure during the tear down process by adapting a vacuum exhaust hose to the deriveting machine. The system was very effective in exhausting the dust generated by the operation. The authors conclude that a potential health hazard existed from asbestos exposure to one employee. The exhaust ventilation program should be maintained and continued to further reduce overall asbestos exposures.

Particular attention was given to the use of various substances during ceramics, metal casting, and other special class activities. The art department was located in the basement of the school; the rooms were supplied with general ventilation through the central heating and cooling system of the school. Local exhaust ventilation is also provided at individual machines and in the kiln room. The 8 hour time weighted average concentration of respirable crystalline silica (7631869) as quartz (14808607) was 42 micrograms/cubic meter (microg/m3) in the personal breathing zone air sample and 69microg/m3 in the area air sample. The respirable particulate concentration was 2.8 milligrams per cubic meter (mg/m3) in personal samples and 2.4mg/m3 in area samples. The quartz content of a bulk clay sample was 19 percent. During bisque firing, the total particulate concentration in the area air sample was 0.1mg/m3. Concentrations of carbon-monoxide, sulfur-dioxide, nitrogen-dioxide, hydrochloric-acid or trace metals during ceramic firing were not significant. Analysis of a bulk sample of the lining of the kiln indicated no asbestos was present. The author concludes that no health hazard existed at the school; a potential hazard may exist if exposures are not properly controlled. The author recommends specific changes in procedures to reduced exposures from art processes.

The evaluation was requested by the superintendant of schools of the county on behalf of the pupils and staff of the school on suspicion of an asbestos hazard in an area where damaged pipe insulation was being replaced. Fibers with an aspect ratio of 3:1 or larger and a minimum length of 5 microns were counted using phase contrast microscopy. Analysis of bulk and settled dust samples confirmed the presence of chrysotile (12001295) asbestos. The majority of the fibers counted, however, were found to be fiberglass (not asbestos) and had a concentration of less than masks used by two maintenance workers had concentrations of 0.18 and current NIOSH standard for asbestos fibers, 5 microns or longer, is minute period. The author concludes that there was no asbestos health hazard present at the school.

Request for the survey was made on behalf of the workers in Area-W because of concern about worker complaints of respiratory problems, sore throats, chronic coughs, skin rashes, nosebleeds, metal taste and green color inside the mouth. All symptoms subsided when away from Area-W. Airborne concentrations of vanadium and asbestos were measured. Pulmonary function tests were performed. Urine samples were analyzed for vanadium. Airborne vanadium concentrations ranged from 0.10 to 0.13 milligrams per cubic meter, which was above NIOSH standards but below OSHA standards. Airborne asbestos ranged from 0.01 to 0.53 fibers per cubic centimeter. One sample was above NIOSH standards but below OSHA standards. Vanadium concentrations in urine were higher in Area-W workers than in workers in other areas, about 21 micrograms per liter compared to about 3 micrograms per liter. Pulmonary function tests were normal. The authors conclude that hazards exist from vanadium dust and asbestos fiber exposures. Improved ventilation is recommended.

The evaluation was requested by Senator Paul Sarbanes on beh lf of about 2200 building residents, to determine the extent to which asbestos had been used, any potential hazards, and necessary abatement measures. Air, settled dust, and bulk fireproofing material samples were collected and analyzed for the presence of asbestos fibers. Air fiber concentrations were below the 0.01 fiber per cubic centimeter limit of detection, and no asbestos fibers were found by transmission electron microscopy. Polarized light microscopic examination of settled dust samples also failed to reveal any asbestos fibers. The bulk samples of the fireproofing material contained 5 to 20 percent crysotile asbestos. The author concludes that no asbestos exposure hazard existed at the time of this survey. He recommends covering an encapsulation of any areas of exposed asbestos, use of accepted control measures during any renovation or maintenance activities, implementation of a respiratory program, periodic inspection and monitoring of the building for the presence of free asbestos fibers, and removal of the fireproofing materials if future monitoring reveals the presence of asbestos fibers in normal work areas.

The survey was requested by the Oil, Chemical and Atomic Workers International Union Local 4/23 on behalf of 165 employees because of reported cases of anthracosis and anthrasilicosis. Air samples were examined for total and respirable particulates, crystalline silica, sulfates, sulfites and polynuclear aromatics. Bulk samples of calcined petroleum coke were analyzed for polynuclear aromatic content. Respiratory examinations were performed. Total particulates ranged from 1.2 to 6.1 milligrams per cubic meter (mg/m3). Respirable particulates ranged from 0.17 to crystalline silica, sulfates, or sulfites were detected. Concentrations of polynuclear aromatics ranged from 0.10 to 36 micrograms/m3. Ten percent of the workers had abnormal pulmonary function test results. Abnormal tests were associated with work in the mobile equipment department. X-rays revealed no job related abnormalities. The authors conclude that a hazard from overexposure to petroleum coke dusts containing polynuclear aromatics exists. More effective methods of dust control are recommended.

The study was conducted at Ideal Cement (SIC-3273) in La Porte, Colorado on June 1 and 2 and July 29, 1982. The evaluation was requested by Ideal Basic Industries on behalf of an unspecified number of workers. Wet Globe Bulb Temperatures in the work area were 84 to 97 degrees-F. NIOSH criteria were calculated to be 79 degrees-F for this type of work. NIOSH criteria for sulfur-dioxide is 5 milligrams per cubic meter (mg/m3); exposures were 25 percent greater than standards for sulfur-dioxide and sulfates. Cyclohexane could not be detected. Respirable particulates exceed the NIOSH criteria of 5mg/m3 by 33 percent. Workers experienced dizziness, eye, nose, and throat irritation, and nosebleeds when cleaning the cyclone equipment. The authors conclude that there is a hazard from overexposures to sulfur-dioxide and respirable particulates, and a heat stress problem when cleaning cyclones. They recommend monitoring sulfur-dioxide and particulates and using a vacuum system for cleanup. Workers should be trained to handle heat stress and an area should be provided to cool off at 20 minute intervals while cleaning cyclones. Work practices for hot cleanouts should be established.

The evaluation was requested in response to employee complaints of dry nose and mouth, and eye irritations associated with the use of a clay like substance during the coating and curing of continuous casting troughs of the blast furnace. The concentrations of formaldehyde and phenol were below relevant federal standards. Samples collected for crystalline silica showed no detectable amounts of quartz or cristobalite. The authors conclude that a health hazard does not exist at the facility due to exposure to airborne formaldehyde, phenol, or crystalline silica. It is recommended that empty sacks of clay be properly disposed of and not be placed in troughs for burning; continuous casting troughs should be allowed to cool prior to stripping and coating; and eating, drinking, and smoking should be prohibited in the work area and allowed only in designated areas.

A representative of the United Steel Workers of America, Local 1011 requested the survey on behalf of 70 production and 7 supervisory personnel. Concentrations of iron-oxide (1309371) ranged from 0.17 to 9.2 milligrams per cubic meter (mg/m3) compared with the OSHA standard for an 8 hour time weighted average of 15mg/m3. Respiratory symptoms included shortness of breath, wheezing, coughing, and phlegm production; the majority of symptoms were reported by cigarette smokers. Pulmonary function evaluations were all within normal limits. The authors conclude that a potential health hazard exists from iron-oxide and particulates, but no mortality or morbidity above that expected for this age group from cancer or heart disease was found. They recommend reduction of dust exposures and limitation of employee exposures by the use of engineering controls such as ventilation. Respirators should be worn by exposed employees workers should be screened for ability and equipment use prior to assignment.

The survey was requested by United Steel Workers of America, Local 1271 on behalf of 750 employees because of the reported high incidence of cancer among workers. A retrospective study of mortality experience was conducted. Quartz (14808607) was the only polymorph of crystalline silica detected above the lower limit of quantitation. Breathing zone samples showed quartz concentrations ranging from 0.04 to 1.24 milligrams per cubic meter (mg/m3), below OSHA standards of 5.0mg/m3. One sample contained iron at a concentration that was 24 percent of the OSHA limit. Manganese and nickel were present at 33 percent or less of OSHA and NIOSH standards. Settled dust was 42 to 72 percent quartz. Unexplained excess risk of cardiovascular renal disease in electric furnace workers and arteriosclerotic heart disease in mechanical maintenance workers was revealed. The authors conclude that a potential hazard exists from respirable crystalline silica. Masons are at risk for work related nonmalignant respiratory disease. Further investigation of silica exposures is recommended.
