Air sampling revealed potential dust exposures as high as 50mg/m3 of total dust while using a powered disc grinder to sculpt. The sculpting process involved grinding with a 6 inch electric disc grinder or using such hand tools as files and chisels. The sculptor used primarily limestone, marble, talc, and onyx, working about 6 hours per day. The talc (14807966) sculpting stone showed the presence of asbestos (1332214) on bulk analysis. The sculptor wore safety glasses with side shields and an appropriate, approved respirator. An industrial vacuum cleaner was used for dust cleanup. The author recommends that the sculptor continue to use the NIOSH approved respirator and that, if possible, the disc grinder not be used on potential asbestos sources such as serpentine (50555) and talc. Wet working of the stone would reduce the dust levels significantly. Several precautionary measures are listed from a publication dealing the health risks associated with common art and hobby materials.

No basic steel is produced at this plant. Raw material in the form of hot rolled coils is received from other plants. The product is directed into one of three channels according to its intended use: 1) tin plate and tin free steel, 2) galvanized (SIC- 3312), or 3) cold rolled products (SIC-3316). The survey included over fifteen different areas or processes. Results of the personal and area samples were used to evaluate employee exposures. The personal samples were attached near the breathing zone of the employees to collect a representative sample of air. Atmospheric samples for particulate oil mist and for sulfuric-acid (7664939) were collected. Atmospheric samples for total dust, chromic-acid (7738945), and zinc-oxide (1314132) were collected on 5 microgram polyvinyl-chloride (9002862) (PVC) filters. Atmospheric samples for methyl-chloroform (71556) were collected on activated charcoal tubes. Atmospheric samples for carbon-monoxide (630080) were taken using Drager colorimetric gas detector tube units. Atmospheric samples for hydrogen cyanide (7408) were collected. An atmospheric sample for asbestos (1332214) was collected on an 0.8 microgram mixed cellulose ester filter at a flow rate of 2.01pm. Atmospheric samples for sodium-hydroxide (1310732) were collected with a fritted glass bubbler. An employee exposure to asbestos at the Deep Well exceeded both ceiling values of 0.5 fibers/cc and 10 fibers/cc respectively. All other samples were below the evaluation criteria.

This abatement period was instituted by OSHA while the facility attempted to correct violations of the airborne lead (7439921) standard. At this site both a lead recovery operation and a foundry were operational. Both were housed in one large building which used to be a grain elevator. The finished products were bearings for journal boxes of railroad cars. The lining of these bearings was composed of 87 percent lead, 3 percent tin, and 9 percent antimony. Electric furnaces melted down the scrap metal and reclaimed the lead. A total of 95 workers were screened using a zinc-protoporphyrin (ZPP) test. Fifty two of the men who had worked at high risk jobs or had a ZPP value equal to or greater than 90 microgram percent were examined by history, physical and laboratory tests. Of these, 85 percent had lead levels greater than 40 micrograms per 100 milliliters of blood and over 20 percent had levels greater than 60 micrograms. Thirty five had abnormally elevated blood pressures and a number had abnormalities of the urine and other parameters of renal function including blood urea nitrogen. During a walk through of the facility it appeared that lead or dust possibly containing lead was present in abundance on floors, worktables and clothing of the workers. The authors recommend that housekeeping be improved, that more vigorous lead monitoring and control programs be instituted, that the abatement program be reviewed to see if workers can be given additional protection, and that abnormalities of kidney function and blood pressure be followed up.

The evaluation was requested by an authorized employer representative on behalf of 92 affected workers. Respirable dust and free silica concentrations generally were below the evaluation criteria of 10 milligrams per cubic meter (mg/m3) divided by the percentage of free silica plus 2, and 0.05mg/m3, respectively; 2 of 21 free silica and 4 of 21 respirable dust samples exceeded the standards. Concentrations of lead and carbon- monoxide (630080) were well below the exposure limits of 0.1mg/m3 and 35 parts per million, respectively. Workers reported respiratory tract symptoms, however these were attributed to contagious respiratory tract infections. The authors conclude that no hazardous exposures exist at this facility, but the dusts may aggravate inflamed respiratory tract mucous membranes. They recommend that properly fitted respirators be used and the housekeeping at the site should be improved.

Medical interviews were conducted with workers and ventilation systems were assessed. An unidentified individual requested the evaluation on behalf of about 400 production employees. All exposures were below environmental criteria and no job related illnesses were discovered. Ventilation was inadequate at the polishing wheels, dip tank, and chrome plating operation areas. They conclude that employees were not exposed to harmful concentrations of the tested chemicals at this facility. They recommend that proper ventilation be used, employee education regarding the use of respirators, written guidelines for respirator use, and the establishment of a materials safety data sheet file.

The evaluation was requested by a company representative on behalf of about 400 production workers. General and personal air samples were collected in seven different work areas, and analyzed for various solvents, gases, and dusts. Workers completed symptom questionnaires. Workplace ventilation also was assessed. Air concentrations of free silica (14808607) (quartz) and cristobalite (14464461), total particulates, toluene (108883), methyl-ethyl-ketone (78933), iron-oxide (1309371), manganese (7439965), chromic-acid (7738945) and chromates, and carbon-monoxide (630080) were assessed. Concentrations were found to be below respective evaluation standards of 0.05 milligrams per cubic meter (mg/m3), 30mg/m3 divided by the percentage of quartz plus 2, 10mg/m3, 375mg/m3, 590mg/m3, 5.0mg/m3, 5.0mg/m3 (ceiling), 0.5mg/m3, and 35 parts per million. None of the workers reported job related health problems. Ventilation systems were not within design specifications for the polishing/buffing, dipping tank, and chrome plating exhaust systems. The author concludes that no hazardous chemical exposures exist. He recommends ventilation improvements, use of personal protective equipment, retesting at selected work sites, and establishment of a Material Safety Data Sheet file.

At the time of the survey the company employed about ten persons. There was one large production line which processed several tons of granular product or pesticide per day. Four or five workers were employed in the production of a liquid product identified as a seed protectant and nutrient mixture. Employees in the granular facility were exposed to concentrations of S-(((1,1-dimethylethyl)thio)methyl)-O,O-diethyl- phosphorodithioate in excess of the environmental criteria. Heptachlor (76448) exposures in the seed protectant area were also in excess of environmental criteria. Employees were exposed to excessive levels of aliphatic solvents, benzene (71432), captan (133062), diazinon (333415), and organophosphates. There was a potential exposure to free silica (7631869) in the granular facility. A significant number of workers reported acute symptoms probably due to excessive pesticide and dust exposures. The authors recommend that immediate action be taken to lower potential exposures by providing improved engineering controls and practices at this site. More frequent cleanup of the screening pit and other areas should be implemented until improved engineering controls can be tried. Strict contamination and decontamination control procedures, a program of employee and management education, a respiratory protection program, improvements in personal protective equipment use and care, improved medical and training practices, and discontinuance of the use of solvents containing benzene are also recommended.

Personal and area air samples were analyzed for total and respirable dust, and 25 workers from the original evaluation were tested for pulmonary function. Eleven workers (ten female, one male, mean age 44 years) had abnormal pulmonary function for at least one tested parameter. No medical or smoking related explanation could be found in six. All but two samples of total soap dust measured on three shifts were below the Threshold Limit Value (TLV) for total nuisance dust (10mg/m3), and all were below the TLV for respirable nuisance dust (5mg/m3). Total dust samples ranged from 1.1 to 18.9mg/m3 and concentrations of respirable dust ranged from 0.18 to 0.73 mg/m3. The authors conclude, as did the earlier study, that highly alkaline soap dust may cause reactions in susceptible individuals due to irritation. The following recommendations are presented: existing ventilation should be operative at all times with measurements taken continuously to ensure that dust exposure is minimized, ventilation should be revised to allow for air recirculation and filtration, employees should use personal protective equipment appropriately, employees should be educated in work procedures and safety matters, a vacuum system should be used in cleanup rather than sweeping, and a medical surveillance program should be initiated.

The survey was requested by the employer on behalf of about 320 employees. Air samples were analyzed for total nuisance particles, respirable particles, and silica. No exposures exceeded the OSHA criteria of 5 milligrams per cubic meter for respirable or total nuisance particles, and no free silica was detected. High volume air samples detected silica as 23 percent of total dust and 16 percent of respirable dust, which exceed the OSHA criteria. The author concludes that a potential hazard exists from silica exposure and recommends that a medical and environmental monitoring program be established, the working environment be evaluated every 6 months, and a respirator use and care program be developed. Improved ventilation, housekeeping procedures, and worker protection practices also are recommended.
