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.

(SIC-3264), Hoboken, New Jersey, on April 18 and 19, 1979. 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.

The evaluation was requested by the management on behalf of an unspecified number of employees. Atmospheric samples for metals were collected on membrane filters, and nickel-carbonyl (13463393) samples were collected through activated charcoal. Atmospheric samples for amines, mercury (7439976) and organics were collected through silica gel tubes, iodine impregnated charcoal and activated charcoal, respectively. Airborne contaminant concentrations all were well below OSHA standards of 1.0 milligram per cubic meter (mg/Cu m) for copper (7440508) dust and 0.1mg/Cu m for copper fumes, 0.01mg/Cu m for mercury, 0.007mg/Cu m for nickel-carbonyl, 750mg/Cu m for toluene (108883), and 435mg/Cu m for xylene (1330207). Fourteen different metals were found on used air conditioning filters. One of two brands of paint used to paint walls shortly before the survey contained mercury. Smoke bomb tests showed that contaminated air from roof exhaust outlets could reenter the facility. The investigators conclude that employees are not exposed to toxic concentrations of airborne contaminants and the odor problems probably are caused by contaminant reentry into the center. They recommend a comprehensive ventilation study, and monitoring and use of ventilation when toxic materials are handled.

The evaluation was requested by the employer on behalf of approximately 80 affected employees. Styrene (100425) concentrations during the initial survey ranged from 200 to 400 parts per million (ppm), exceeding the 100 ppm OSHA standard. Reported employee symptoms were consistent with symptoms caused by styrene overexposure. Methylethyl ketone peroxide (MEKO) concentrations ranged from none detected to 13 milligrams per cubic meter (mg/m3), exceeding the 1.5mg/m3 American Conference of Governmental Industrial Hygienists Threshold Limit Value as measured during spray up fabrication. Peak levels of styrene exceeded the 600ppm OSHA standard for peak measurements in two instances. The 200ppm OSHA ceiling for 5 minute exposure was equalled in one sample. The author concludes that workers were exposed to potentially toxic concentrations of MEKO and styrene vapor and less significant concentrations of acetone vapors. The author recommends that one of the ventilation systems be improved, that the practice of removing dust using compressed air be discontinued and replaced with a vacuum system, and that two work stations be relocated so as to be directly in front of the exhaust hoods.

Samples analyzed for zinc-oxide (1314132), aluminum (7429905), iron-oxide (1309371), cadmium (7440439), xylene (1330207), acetone (67641), and beryllium (7440417) were below evaluation criteria. Copper (7440508) fume concentrations ranged from 0.1 to 1.5 milligrams per cubic meter (mg/m3), exceeding the OSHA standard of 0.1mg/m3, and total dust concentrations ranged from 12.4 to 18.2mg/m3, exceeding the OSHA standard of 15mg/m3. Ozone concentrations ranged from 0.005 to 1.0 parts per million (ppm) during welding, exceeding the OSHA standard of 0.1ppm. Interviewed workers reported work associated symptoms, with worse symptoms when the welding process involved galvanized steel. The authors conclude that a health hazard exists for the welders, and spray painters may have been exposed to excessive solvent vapors when painting in poorly ventilated areas. They recommend that local exhaust ventilation be installed in all welding locations and that welding curtains be installed to protect other workers from flash burns.

The evaluation was requested by the Business Representative for the Chicago Web Pressmans Union Number 7 on behalf of 350 pressmen, Junior Pressmen, and Apprentice Pressmen working in the pressroom. Many of the complaints and health problems reported by employees were not associated with ink mist exposure. One personal sample exceeded the OSHA standard of 5 milligrams per cubic meter (mg/m3) for ink mist. Oil mist combined with ink mist during roller lubrication generated excessive mist exposure for the pressman. Airborne trace metals were below hazardous concentrations. Atmospheric sampling and analysis of black ink did not reveal the presence of polynuclear aromatic hydrocarbons. Benzidine (92875) and 3,3'-dichlorobenzidine (91941) were not detected in the atmospheric yellow ink mist samples. The concentration and composition of the airborne paper dust was not considered hazardous. The author concludes that inhalation of ink mist and paper dust at the concentrations found in the pressroom did not pose a health hazard at the time of the surveys. Precautions should be taken to minimize exposure of the pressmen to ink mist generated by operating presses, pressmen should wear the disposable single use mist masks when servicing operating printing units, that pressmen who come in contact with inks should be instructed to wash their hands before smoking or eating, kerosene should be stored in fire resistant safety containers with self closing lids, and cleanup personnel should be provided with protective clothing.
