During a preliminary survey, CO, formaldehyde, and chlorine were measured. Dust samples were collected and data was gathered on workplace practices, materials, controls, and ventilation. During a follow up evaluation, personal breathing zone and environmental samples were taken in the cast house, rolling mill, and finishing and maintenance departments. Employee interviews were conducted and air flow measurements were made. Four of five welders examined during working hours showed concentrations of nickel in their breathing zone which exceeded the recommended standard of 0.015 milligrams per cubic meter with the highest being more than 5 times that concentration. CO measurements in two working areas exceeded the 35 parts per million recommended standard by 15 to 30 percent. Values for all other substances were below all standard criteria. TDA exposure was judged to be below toxic concentrations, although no standard had been established for this substance. Responses during the interview of 43 employees indicated few job related complaints except occasional overexposure to irritant vapors (ten cases). Other intermittent symptoms included shortness of breath in two cases and one each of facial dermatitis, dizziness, dermatitis, chest pains, and headache. Air velocities from 600 to 1200 flow per minute were recorded in the furnace and rolling mill areas due to open doors and windows. The author concludes that environmental concentrations of most contaminants were below NIOSH evaluation criteria. Engineering modifications are recommended to cope with the ventilation of certain areas, especially during seasons when the doors and window must be kept closed.

The distribution room measured 12 feet in all dimensions and was enclosed on three sides. Methadone had previously been received in prepackaged doses, but more recently the nurses had to count the contents of each 100 count bottle of methadone-hydrochloride (1095905) and separate tablets or diskets into individual doses. A small amount of pink orange dust, due to chipping and breakage of pills, was noted during the on site visit, on the countertops where the drug was counted. Nurses involved in dispensing the medication reported intermittent sleepiness, itching of the face, nose, and eyes, and dryness of skin on the hands and face. Urine studies indicated no detectable methadone or methadone metabolites at a limit of 1 microgram per milliliter. The authors conclude that there is no evidence of methadone absorption; however, they recommend that skin contact with the tablets and diskets be kept to a minimum by use of instruments for moving the pills on the counting tray, frequent clean up of dust, and periodic hand washing.

An unidentified individual requested the evaluation on behalf of an unspecified number of workers, work processes and hygienic practices were reviewed. The chemicals were used in powder form and were manually scoped from the bag with a tin can and poured into a mixing basin through a plastic funnel. No protective equipment was used. The author concludes that the exposure was intermittent and minimal and that polyacrylamide pose little or no health problems to the normal individual, and consequently no health hazard from exposure to these polyacrylamides existed at this facility. She recommends the installation of an automatic dry or liquid chemical feeder to minimize worker contact with the chemicals, and the use of the chemicals in a liquid, rather than solid form, to eliminate dust generation.

(1978) General American Transportation Corporation, Masury, Ohio. (Click to open report) Environmental and medical surveys were conducted on April 4 to 7, 1977, and June 7 to 9, 1977, to determine employee exposures to dust fumes, smoke and gases from welding and plasma arc cutting, isocyanate (661201) vapors and x-ray radiation at the General American Transportation Corporation (SIC-3743) in Masury, Ohio. Authorized representatives of United Steelworkers of America, Local 1534 and 2318, requested the evaluation on behalf of approximately 1000 affected workers. Twenty four of 52 emp...

Authorized representatives of United Steelworkers of America, Local 1534 and 2318, requested the evaluation on behalf of approximately 1000 affected workers. Twenty four of 52 employees were exposed to concentrations of fluoride (16984488), copper (7440508), iron-oxide (1309371), nickel (7440020), chromium-VI (7440473), vanadium (7440622) and total particulates in excess of OSHA standards. Concentrations of carbon-monoxide (630080), formaldehyde (50000) and polymethylene-polyphenyl-isocyanate (9016879) also exceeded current OSHA exposure limits. No abnormalities other than abrasions and burns associated with welding and heavy metal handling were found. The author concludes that excessive contaminant emissions are produced from welding, air arc repairing, chipping and gouging, bank cleaning and grinding. Local ventilation should be instituted to control excessive emissions, respiratory protection should be used, fibrous glass insulation treated with resin materials and used to seal annealing furnace doors should be substituted with a safer material, undue exposure to isocyanates should be avoided when handling urethane foams, and continuous surveillance should be maintained on all radiography equipment.

Bricklayers and helpers, and occasionally laborers, during the installation of Fiberfrax in heat treat furnaces complained of coughing spasms, sore throats, and skin irritation. Because Fiberfrax was being used as a thermal barrier during welding repair of die blocks, the evaluation was expanded to include this operation. The potential exposures to silica (7631869) and total and respirable particulate by bricklayers were evaluated. Additionally, exposure to iron-oxide (1317619) fume by welders during repair of a cracked die block was evaluated. Personal breathing zone samples were collected to evaluate the bricklayers' and helpers' exposures to quartz (1317799) and cristobalite and respirable and total dust. Health questionnaires were completed on six workers (four bricklayers and two welders). This constituted 100 percent of the total workers (six males) exposed. The bricklayers and workers are experiencing short term toxicity characterized by irritation of exposed skin areas, and less frequent symptoms of mucous membrane irritation. Health effects data concerning long term exposure to airborne Fiberfrax was not available. Bricklayers were exposed to airborne quartz levels exceeding the federal standard and to excessive levels of total particulate during replacement of two gas burners in the heat treat furnace. The welders were not exposed to toxic concentrations of metallic oxide fume during repair of a cracked die block.

Materials involved in fabrication of these products are felt, asphalt (petroleum), colored granules, limestone (1317653), talc (8030840), and mica (12001262). Medical evaluation was conducted by use of a medical questionnaire at the beginning and end of a day's shift. Questions concerned the employees' perception of irritated eyes, nose and throat or skin itching. Environmental sampling was designed to include all job descriptions in either breathing zone or general area samples. The data reveal that in certain work areas there were concentrations of total dust and free silica (7631869) in excess of evaluation criteria based on breathing zone concentrations. The saturator man's exposure to asphalt fumes at most times is not considered to be toxic. Excessive concentrations of total dust and asphalt fumes were present in the area above the coater. Employees' exposure to benzo(a)pyrene (50328), other polynuclear-aromatic-hydrocarbons, beta-naphthylamine (91598), aliphatic and aromatic-hydrocarbons were not toxic at concentrations found. There were no indications of eye, nose, throat or skin irritations.

The area of concern was in the pouring stand of the Pit section of the basic oxygen furnace shop. Atmospheric samples for lead were collected on Millipore filters Type AA (mixed cellulose ester) with breathing zone using a battery powered vacuum pump. Area samples were collected with the same equipment along the pouring stand. The medical evaluation included interviews, physical examinations, and blood chemical analysis. It has been determined that a potential hazard to the health of the workers exposed to lead dust and fumes exists. Ten of thirteen personal samples for inorganic lead exceeded the proposed 100 micrograms of lead per cubic meter of air (microgram/M3). Eight personal samples exceeded the current lead standard of 200 micrograms/M3. These concentrations ranged from 25 to 2600 micrograms/M3 of lead. Of the 16 blood lead analyses, three were in excess of 60 micrograms of lead per 100 milliliters of whole blood (60 micrograms/100ml), five were in the range of 40 to 60 micrograms/100ml, and eight were less than 40 micrograms/100ml. It is recommended that a blood lead level of 60 micrograms/100ml or less be allowed as a safe concentration.

(SIC- 2819) which produces a variety of chemical substances, many of which serve as feedstock to produce the final products. The majority of the substances are produced and handled in closed reactor systems and distillation units. The final products are loaded into tank cars, trucks and drums. General area and personal samples for organic vapors were obtained. Private interviews with employees selected at random were conducted and nondirected medical questionnaires were compiled. The first aid facilities and medical programs were also reviewed along with selected blood lead (7439921) data. A hazard to the health of laboratory workers did not exist at the time of the surveys as indicated by air sampling results. A potential health hazard existed for workers assigned to the refinery gas feedstock unit, due to benzene (71432) vapor exposures as indicated by air sampling results. A health hazard was not indicated for employees of the ethanolamine (141435) production unit based on the results of the type of air samples obtained. A health hazard was not indicated for employees of the phenol (108952) processing unit based on the results of the type air samples obtained. A determination of potential health hazards was not possible for the Cell Renewal Area due to the operation not being on line at the time of the surveys. A potential health hazard existed for employees of the DDM production unit based on work practice observations and spent catalyst dust analysis. The spent catalyst contained approximately 0.6 percent aniline (62533) and 9 percent diaminodiphenyl-methane (DDM) isomers by weight. The workers were not adequately protected for the catalyst dumping operation.
