Maintenance personnel working inside the kiln at times of shutdown reported respiratory and eye irritation. Personal breathing zone samples were collected during the next shut down while workers were removing and replacing 25 feet of refractory brick at the front end of the kiln. Area samples were collected for chlorine (7782505), inorganic acids, sulfur-dioxide (7446095), oxides of nitrogen, ozone (10028156), respirable dust, total and inhaled dusts. Ozone was detected at 0.6 to 0.7 part per million (ppm) when conditions during previous episodes were recreated. Ozone was detected through a portal at the back end of the kiln at well over 0.7ppm. A direct reading meter revealed a concentration of 4.5ppm. When the induced draft fan was turned off, ozone from an electrostatic precipitator apparently back drafted into the kiln. The authors conclude that the eye and respiratory irritation were a result of ozone exposure.

Personal breathing zone samples, area air samples, and wipe samples were collected. The highest airborne lead concentrations were collected during maintenance activities; 22 micrograms/cubic meter (microg/m3) during sweeping and 140microg/m3 during cleaning of target retrieval rails. All air samples collected during firearms training had detectable levels of lead with six ranging from 0.7 to 9.5microg/m3. Wipe sampling indicated lead concentrations ranging from 2.5 micrograms per 100 square centimeters (cm2) on a kitchenette countertop to 1,100 micrograms/100cm2 in a gun cleaning tray in a classroom. Analysis of the bulk sample indicated 45,000 micrograms lead/gram sample in floor sweepings. The author concludes that airborne lead was not causing a health hazard for these individuals but that some exposure could result from surface contamination. Lead ingestion can be avoided through good hygiene practices. Respiratory protection equipment should be provided during maintenance operations.

This investigation centered around Nicks Silica Company (SIC-1446), Jackson, Tennessee. The study population included workers with 1 year or greater cumulative tenure subsequent to the opening of the mill in the grinding area or in areas downstream of the grinding process. A medical survey was conducted which included a questionnaire, spirometry, and a single view posterior/anterior (PA) chest X-ray. None of the 12 current and former workers participating in the survey had changes on their chest X-ray consistent with silicosis. One participant showed an abnormal spirometry pattern. Three reported chronic respiratory symptoms. All four participants with positive findings were current cigarette smokers. Because of the long latency usually associated with chronic nodular silicosis, the finding is not sufficient to conclude that current silica dust exposures are without any adverse effect. The author recommends that the medical monitoring program be modified to include classification of chest X-rays by a B-reader.

Potentially hazardous lead exposures were measured during exterior dry scraping and wet scraping of LBP1 with maximum exposures of 120 and 63 micrograms/cubic meter, respectively. Sixty eight of the full time employees participated in a medical evaluation. Ten persons, all field personnel, had a blood lead level of 10 micrograms/deciliter (microg/dl) or greater. Four had levels of 15microg/dl or greater, with the highest being 17.5microg/dl. All of the 126 paint chip samples collected from 49 painted work surfaces in 15 homes had detectable lead, ranging from 0.0022 to 58%. Twelve surface dust samples collected on floors in six homes during renovation on average had lead loadings hazardous to children. The authors conclude that there were potentially hazardous exposures during wet and dry scraping; these tasks were infrequently performed. The average surface levels in homes undergoing renovation were potentially hazardous to young children. Surface levels in the workers' personal vehicles were also potentially hazardous.

Two employees had a Parkinson like disease which could be related to chronic manganese (7439965) toxicity. Investigators reviewed and analyzed company records and conducted air sampling for manganese dust. The 29 full shift evaluations for total manganese showed 8 hour time weighted average personal breathing zone concentrations ranging from 0.05 to 0.40mg/m3. All findings were below allowable limits. A cross sectional medical survey indicated symptoms of tiredness, muscle aches, and cramps and the physical finding of tremor was found more frequently among production and support workers than among nonproduction workers. There was no statistical association between symptom indices for concentration, memory, anxiety, depression, motor function, and tremor with work at the electrolytic manganese- dioxide facility. Work in the ferromanganese furnace departments outside the facility was associated with symptoms of declining concentration, memory, and motor function. However, these workers may have been exposed to potential neurotoxicants other than manganese. The authors conclude that no statistical association was seen between work in the factory and adverse health outcomes. The authors recommend that employee exposures be reduced.

The primary objective was to estimate and report the prevalence of silicosis among participating current and former employees at the grinding area and/or downstream of the grinding area at each operation by tenure and job. Of the 28 current and former workers who participated in the medical survey, six (21%) had a chest X-ray considered to be consistent with silicosis. The prevalence among current workers was 10%. The highest median International Labour Office (ILO) profusion category was 2/3. Three participants had a chest X-ray consistent with progressive massive fibrosis. Two had "A" size large opacities and one had "C" size large opacities. None who had been working less than 10 years had a positive chest X-ray. The prevalence of silicosis among the group who met the study criterion, yet chose not to participate in the medical survey was 8%. Pulmonary function testing revealed that eight of the 25 participants who performed spirometry had abnormal patterns, and all eight exhibited an obstructive lung pattern. The author recommends that the frequency of medical monitoring examinations be increased.

Metal concentrations were measured in 45 personal breathing zone (PBZ) samples; an additional 12 PBZ samples were monitored for exposure to respirable dust and silica (14808607). Eight bulk ash samples and 11 hand wipe samples were taken. The workers put in 60 hour work weeks, 10 hours a day for 6 days. Arsenic was detected in 18 samples and ranged from 0.30 to 31 micrograms/cubic meter (microg/m3) with three of the samples exceeding the adjusted OSHA permissible exposure limit of 5.6microg/m3. In 11 samples, beryllium (7440417) was detected, and ranged from 0.02 to 0.04microg/m3. Cadmium (7440439) was detected in seven samples and ranged from 0.17 to 2.5microg/m3. Both the beryllium and cadmium concentrations were below the allowable limits. Lead (7439921) concentrations were measurable in 12 samples and ranged from 1.7 to 1,82microg/m3, with one sample exceeding the OSHA limit of 28microg/m3. Crystalline silica was below the detectable limit. Wipe samples collected from the hands of the employees indicated the potential for exposure through ingestion. The author concludes that there was a potential hazard from exposure to arsenic, beryllium, and lead. The author recommends that housekeeping procedures and work practices be improved to reduced exposures.

(SIC-3061), Logansport, Indiana. The facility produced automotive vibration control products using rubber stock and metal parts. Nearly 5,000 individuals were employed in the facility on three shifts. Department 634 included the molding process, metal preparation processes, paint dip tanks, elastomer adhesive spray processes, grinding and buffing operations, assembly and packaging of the products. Twenty one employees described dermatologic symptoms which they felt were work related. Seventeen of these 21 had sought help from a physician and the final diagnoses included nonspecific dermatitis in three, and one case each of irritant contact dermatitis, nummular dermatitis, irritant or allergic contact dermatitis, dyshidrotic eczema, lichen simplex chronicus, urticaria, blister, rosacea, alopecia areata, furuncles, urticarial vasculitis, nummular psoriasis, and psoriasis. Exposures that the workers subjectively associated with their symptoms included oils, sprayer, paint lacquer, cleanser, heat, soap, adhesive, dust and solvents. The authors conclude that no specific explanation was found for the increase in skin problems at the facility, although workers had potential exposure to multiple known skin irritants and allergens.

The indoor facility was located in an old office trailer. Sampling was conducted during the firing of copper jacketed lead free primer ammunition. Air sampling indicated that airborne lead concentrations were below the minimum quantifiable concentration. Wipe samples from surfaces inside the trailer revealed lead concentrations ranging from 6.6 to 31.6 micrograms/100 square centimeters. The surface contamination likely resulted from the use of lead containing ammunition by other police forces. Ventilation was provided through two 14 inch axial fans located in the sidewalls of the trailer. The author concludes that the firing of copper jacketed lead free primer ammunition did not present a health hazard, but the continued use of lead primer ammunition by other departments may expose officers to lead from surface contamination.
