Breathing zone samples were analyzed for asbestos content. Concentration levels of fibers greater than 5 microns in length were shown to be 0.90 fibers per cubic centimeter to levels too high to analyze. These levels exceeded the OSHA standards of two fibers per cubic centimeter for fibers greater than 5 microns in length in all but two instances. The results show that an asbestos hazard does exist. The proper use of respirators and the education of employees about the dangers of asbestos exposure are recommended. Worker hygiene practices also are suggested.

The evaluation was requested by the production superintendent on behalf of about 45 employees. The employees were monitored with a dosimeter, and a noise classifier monitored the looms. Nine of the 13 loom operators monitored were potentially exposed to noise levels exceeding the OSHA standard of 90 decibels relative to the A-weighted scale (dBA) for an 8 hour exposure. Sound pressure measurement at loom platforms ranged from 93 to 101dBA. Personal dosimetry measurements ranged from 0.4 to 2.5 times the permissible limit. Earplugs provided to workers had sufficient attenuation capabilities based on a comparison of their mean attenuation to the octave band sound pressure levels generated by the looms. The investigators conclude that noise in the weaving department potentially could exceed permissible limits. They recommend reducing employee exposure to noise by engineering controls, using ear protectors until effective engineering controls are implemented and audiometric testing of personnel assigned to high noise areas. They also recommend environmental sampling to evaluate cotton dust and asbestos (1332214) exposure, if the weaving room ceiling is composed of asbestos.

(1979) Saint Elizabeth's Hospital, Washington, D.C. (Click to open report) A total of six area and breathing zone air samples were collected on March 19, 1979 at Saint Elizabeth's Hospital, (SIC-8062) Washington, D.C., to determine if dust emitted during the installation of fire alarms and smoke detectors could present an asbestos (1332214) exposure potential. Bulk samples of ceiling and wall boards also were collected for qualitative analysis. Sampling was prompted by a request from the safety manager at the hospital.

Bulk samples of ceiling and wall boards also were collected for qualitative analysis. Sampling was prompted by a request from the safety manager at the hospital. Air samples were analyzed using phase contrast microscopy, and bulk samples were analyzed using electron microscopy. All sample analyses resulted in fiber counts below detectable limits, and, consequently, less than OSHA standards (2.0 fibers greater than 5 microns in length per cubic centimeters of air). It is recommended that eye protection equipment be used to prevent injury from flying particles, chips, and other debris. Helmets should be used in situations in which workers are subjected to impact from falling or flying objects. The OSHA noise standard should be adhered to when using power drills and pneumatic drills. NIOSH approved respiratory protection also should be provided when this equipment is used.

The evaluation request came from the institution to evaluate the effectiveness of control efforts that were instituted following a previous evaluation. Sampling equipment was placed at various sites throughout the buildings and phase contrast microscopy was used to analyze the samples. Rainfall provided a disturbed condition. All 20 samples taken were below the analytical limit of detection (0.01 fibers per cubic centimeter), and below the OSHA standard of 2 fibers per cubic centimeter for an 8 hour time weighted average. Although the insulation material contained up to 75 percent asbestos, masonite panel covers were effective in controlling airborne asbestos fibers. The author's general recommendations include regular vacuuming, sampling when environmental conditions change, and using sealants. Special recommendations for the Fine Arts Building include air sampling in the attic during maintenance procedures, the use of respirator protective equipment, and regular clearing of asbestos from the ventilation system. In unoccupied buildings, insulation material should be removed when possible and surveillance should continue when removal is not feasible. Dropped ceilings or paneled enclosures are acceptable means of control. Development of the Smithsonian health, safety, and hygiene program should be continued.

An unidentified individual requested the evaluation for approximately 120 affected workers. Bulk and personal area air samples were analyzed. Airborne concentrations of isopropanol, toluene, mineral spirits, and n-butyl-acetate were well below the environmental criteria of 948, 375, 350, and 710 milligrams per cubic meter (mg/m3), respectively. t-butyl-4-ethyl-phenol (96708) and 2,6,di-t-butyl-4- ethyl-phenol (4130421) were detected in trace amounts. Carbon- monoxide exposures were reduced below the OSHA standard of 57mg/m3 following tuning and maintenance of propane powered forklift trucks. One personal sample of total nuisance particulates (11mg/m3) exceeded the environmental criteria of 10mg/m3. An absenteeism epidemic began with symptoms consistent with toluene intoxication, but subsequent outbreaks could not be related to any special exposure. The authors conclude that after the initial illnesses, stress and anxiety were probably responsible for the epidemic. Recommendations resulting from the evaluation include implementation of a safety and hazard education program, review of engineering controls, improved communication between management and workers, better housekeeping, and modification of the respiratory protection program.

(1979) Tammsco, Incorporated, Tamms, Illinois. (Click to open report) A study was conducted of current and ex-workers at a silica (7631869) mining facility (SIC-1446), Tammsco, Incorporated, located in Tamms, Illinois in order to determine whether workers were being exposed to hazardous levels of silica dust and what the prevalence of silicosis was among current and former employees. The silica dust in question was approximately 100% alpha-quartz (14808607). Mean particle size from air samples in the facility was 5.2 micrometers. Of 34 samples taken, 28 exceeded t...

The silica dust in question was approximately 100% alpha-quartz (14808607). Mean particle size from air samples in the facility was 5.2 micrometers. Of 34 samples taken, 28 exceeded the NIOSH recommended standard of 0.05mg/m3. One individual sample was several hundred times this level. Of the 30 current workers, 25 participated in the study along with 11 of 31 eligible former workers. No evidence of silicosis on radiographic exam was found in workers with less than one year of exposure. Three of 15 current workers with one or more years of exposure and 4 of 11 exworkers had radiographic changes indicative of silicosis. NIOSH concluded that a hazardous situation existed at this site and that continued exposure at these levels would result in shortened life times for the exposed workers. Recommendations called for the immediate implementation of workplace improvements including the following: installation of a high efficiency vacuum system to vacuum work clothes prior to removal; intensification of general housekeeping to prevent dust accumulation; elimination of dry sweeping or blowing with compressed air; and institution of engineering controls to protect the bagger. Other recommendations include periodic environmental monitoring, personal respiratory protection, comprehensive medical examinations for exposed workers, and job transfers for workers with evidence of silicosis.

An evaluation request came from the United Steelworkers of America, Local Number 1123, on behalf of the pithand workers engaged in mold cleanout and preparation activities at the stripper building. The quartz (14808607) concentrations of free silica in the air ranged from 123 to 286 micrograms per cubic meter which exceeded the OSHA respirable dust permissible exposure limit of 10 milligrams per cubic meter (mg/m3) of air divided by the percentage of quartz plus 2. The bulk refractory material used in the operation did not contain asbestos (1332214) or fibrous glass, but did contain a mineral wool fiber of monocalcium-silicate (37323903), which was identified as the probable cause of skin irritation reported in 12 confidential employee interviews. Analysis of the powdered CTPV indicated concentrations of benzene extractables of 0.03 to 0.118mg/m3, which were below the OSHA standard of 0.2mg/m3. The author concludes that at the survey time, pithand employees were exposed to hazardous concentrations of free silica, an inadequate respiratory protection program was in effect, and the CTPV mixture contained known and suspected carcinogens. They recommend implementation of engineering and administrative controls to reduce employee exposures to hazardous materials, particularly the installation of a negative pressure vacuum system for mold cleanout.

The evaluation was prompted by a request from an authorized representative of approximately 35 employees to investigate a complaint of irritations from exposure to what was described as gray fuzz from the heating and cooling vents. Air samples were analyzed for total and respirable particulates, and fibrous-glass (14808607) content. Concentrations of total dust (0.05 milligrams per cubic meter of air (mg/cu M)), respirable dust (0.03 mg/cu m), and fibrous glass (not detectable) were all below OSHA limits (15 mg/cu m, 5 mg/cu m, and 0.01 fibers per cubic centimeter of air, respectively). It is concluded that there was no health hazard present and that the worker who completed the questionnaire had experienced an individual sensitivity to the gray fuzz. Observations are presented concerning potential worker discomfort due to fibrous-glass exposure.

The evaluation request was received from an authorized representative of Local 1936, International Brotherhood of Electrical Workers, and was prompted by worker complaints of eye and throat irritations, headaches, nausea, and concern over long term effects of asbestos (1332214) exposure. Measured concentrations of asbestos ranged from undetectable to 0.41 fibers per cubic centimeter of air. The concentrations were less than the OSHA standard of 2 fibers per cubic centimeter of air, greater than 5 microns in length, but did exceed OSHA policy requiring medical examinations for employees exposed to over 0.1 fibers per cubic centimeter of air. ventilation measurements reveal that air flow in the section generally was inadequate. Improvements of the ventilation system, and annual medical examinations for employees exposed to asbestos are recommended.
