The evaluation was requested by the company. The facility employs 250 workers with an unspecified number working in the M.O. and T.G. rooms. Personal breathing zone and area air samples were taken and analyzed of each for the contaminants. Bulk samples were analyzed for silica content. Sample results for the contaminants ranged up to 20 percent of the recommended exposure limits. Bulk samples did not contain silica. The authors conclude that the exposures to the sampled substances were not hazardous to the employees at the time of the investigations.

The evaluation was prompted by a request from the company management to determine potential toxic exposures of approximately 300 employees from a variety of solvents, paints, particulates, metal electroplating solutions, and isocyanates. Breathing zone samples were analyzed for methyl-ethyl- ketone (78933), toluene (108883), xylene (1330207), methylene chloride (75092), crystalline-silica (14808607), total particulates, methylene-bisphenyl-isocyanate (101688), chromium (7440473), nickel (7440020), asbestos (1332214), trichloroethane (71556) and naphtha (8030306). All samples were well within current OSHA standards. The medical interviews revealed no significant complaints. It is concluded that no hazard existed at the time of this evaluation, but several safety violations were cited including blocked passageways, underground storage of chemicals, and improper disposal of solvent soaked rags. Recommendations are made to store all chemical containers at ground level, enforce workplace hygiene practices, and brief workers periodically on the chemicals they use and their associated hazards.

An evaluation request came from an authorized representative of the approximately 60 affected workers. The airborne concentrations of respirable free silica in three personal samples exceeded the NIOSH recommended standard of 0.05 milligrams per cubic meter (mg/CuM), and ranged from 0.013 to evaluation criteria. The author recommends reducing crystalline silica by using engineering controls, institution of a respiratory protection program, enclosure of the mold spinning machines, and the control of peak exposures to air contaminants by the installation of local ventilation systems on respiratory protection equipment.

(SIC-3361), in Englewood, Colorado. The evaluation request to identify any potentially toxic workplace exposures for approximately 50 employees came from an employer representative. Concentration of inorganic lead (7439921) ranged from 0.03 to 3.2 milligrams per cubic meter (mg/cum) and exceeded the OSHA standard of 0.05mg/cum in 44 percent of the samples. Crystalline silica (14808607) concentrations exceeded the OSHA standard of 0.29mg/cum in 77 percent of the samples. All other sample concentrations were below criteria. Blood lead concentrations exceeded the OSHA standard of 40 micrograms per 100 grams of whole blood in 81 percent of the workers, and 72 percent had free erythrocyte protoporphyrin determinations above the normal range of 356 to 662 micrograms per liter of red blood cells. The investigator concludes that workers were exposed to hazardous concentrations of inorganic lead and crystalline silica, and other toxic exposures could occur if production conditions change without corresponding ventilation improvements. The use of respirators, protective hearing devices and clothing; improvements of workplace hygiene and ventilation systems; and periodic medical surveillance until all exposures are below criteria are recommended.

The sampling was prompted by a request from an authorized representative of the Teamsters Union to determine the potential toxic effects of the agent. X-ray analysis of the approximately 6 percent amount of free crystalline-silica (quartz) (14808607) contained in the sample shows that silica (7631869), potassium (7440097), calcium (7440702), titanium (7440326), iron (7439896), and aluminum (7429905) were the major constituents of this substance. It is concluded that Zorb-All is not hazardous to dock workers at the terminal because of its low content of toxic material and large particle size. It is recommended that the agent be cleaned up after its use before a dry powder residue is formed, which might become airborne and cause irritation of the eyes, nose, or throat.

The request came from an authorized representative of Local 8042, United Steelworkers of America to evaluate potential health problems. Several samples in each area of the facility exceeded OSHA standards for acceptable exposures to respirable crystalline-silica (10 milligrams per cubic meter divided by the percentage of quartz plus 2) and respirable dust (5 milligrams per cubic meter). Four out of five asbestos samples exceeded the recommended OSHA limit of 0.1 fibers per cubic centimeter. Chest x-rays revealed few cases of radiologic abnormalities, a low incidence of chronic bronchitis and restrictive pulmonary dysfunction, and some obstructive ventilatory dysfunction. Bronchitis occurred primarily in women, and smokers were vulnerable to ventilatory dysfunction. A potential health hazard was confirmed for workers in granule mixer, batch scale, lancaster mill, rouse mill, and blow off operations. The authors' recommendations include annual medical examinations that include x-rays and pulmonary function tests; reassignment of workers with suspected abnormalities; ventilation and other engineering improvements in the mixing ball mill, spray dry cutting, sagger filling, and machining departments; use of respiratory and personal protective clothing and goggles; and provision of shower facilities.

An authorized employee representative requested the evaluation to assess toxic exposures of 10 to 20 employees. Gas chromatographic sample analysis revealed that all contaminants were below OSHA criteria for crystalline-silica, and respirable and total particulates (10 milligrams per cubic meter divided by the percentage of quartz plus 2, 5 milligrams per cubic meter, and 15 milligrams per cubic meter, respectively). No standard exists for exposure to the insecticide, but measured concentrations were low (0.002 to 0.011 milligrams per cubic meter). The authors conclude that no health hazard to workers existed at the time of the evaluation and recommend enclosure of local exhaust ventilation hoods, use of personal protective equipment to prevent oral and eye exposures, and continuation of a program of cholinesterase monitoring.

The silica dust on site was approximately 100% alpha-quartz (14808607). Median particle size from air sampled in the facility ranged from 2.3 to 4.9 microns which is well within the respirable range. Of the 57 samples taken, 49 were above the NIOSH recommended limit of workers with less than one year exposure. Three of the fifteen current workers with one or more years of exposure and 14 of the 24 exworkers studied had radiographic changes indicative of silicosis. In workers and exworkers with one or more years of exposure, 17 of 39 had x-ray evidence of silicosis. This very high prevalence of silicosis is due to the respirable size of the particles. It was recommended that engineering controls be implemented to reduce and maintain free silica dust levels to current acceptable exposure limits. The conclusion of the study was that there is a significant health hazard present at this location and continued worker exposure will cause irreversible harm to such a degree as to shorten life.

Breathing zone and general room air samples were analyzed for phosphorus-pentoxide (1314563) (P2O5), elemental-phosphorus, crystalline-silica (7631869), total particulate, fluoride, and vanadium-pentoxide (1314621). Concentrations of P2O5 ranged from 1.7 to 9.2 milligrams per cubic meter (mg/cu m). No OSHA criteria currently exists for this compound. In 3 out of 4 respirable crystalline-silica samples, concentrations ranging from 0.09 to 0.183mg/cu m exceeded the OSHA standard of 10mg/cu m divided by the percent of respirable quartz (14808607) plus 2. All other samples were within the most recent evaluation criteria. The author concludes that a potential health hazard from excessive airborne concentrations of P2O5 and respirable crystalline-silica existed and recommends maintaining the current respirator program, insuring proper fit of respirators, briefing workers on potential hazards, and improving local and general ventilation.

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.
