(1987) Artistic Awards, Colorado Springs, Colorado. (Click to open report) In response to a request from Artistic Awards Co. (SIC-3499), Colorado Springs, Colorado, a study was made of possible exposure to lead (7439921) during lead medallion production. An elevated blood lead level had been found in one worker with symptoms of weakness and fatigue. Personal breathing zone air samples obtained from the areas of casting and engraving showed levels of 7.3 to 8.0 micrograms/cubic meter (microg/m3). Samples collected during grinding and buffing of lead medallions indicated... (Click to show more)In response to a request from Artistic Awards Co. (SIC-3499), Colorado Springs, Colorado, a study was made of possible exposure to lead (7439921) during lead medallion production. An elevated blood lead level had been found in one worker with symptoms of weakness and fatigue. Personal breathing zone air samples obtained from the areas of casting and engraving showed levels of 7.3 to 8.0 micrograms/cubic meter (microg/m3). Samples collected during grinding and buffing of lead medallions indicated lead concentration in the breathing zone of 1300 to 1900microg/m3. Each of four grinding and buffing stations was fitted with a well enclosed ventilation hood. At one station, the ductwork was clogged with buffing wheel material and ducts at the other three stations were disconnected inside the cabinets. Excessive levels of lead in the air resulted from a lack of local exhaust ventilation in this area. Workers in this room wore half face respirators; however, the respirator which was worn by the worker who had the elevated blood lead level failed to pass a fit test. After improvements had been made, the ventilation system was observed to be very effective. Lead exposures during buffing and grinding operations had been reduced to below the limit of detection, 6microg/m3. The author concludes that one worker has been overexposed to lead due to a poorly fitted respirator, and possibly to ingestion of lead deposited on food or drinks.

(1987) Bondar-Clegg, Lakewood, Colorado, Sparks, Nevada. (Click to open report) In response to requests from management of Bondar-Clegg (SIC-7397) located in Lakewood, Colorado and Sparks, Nevada, evaluations were made of exposure to lead (7439921) in two fire assay laboratories. Breathing zone and general room air concentrations of lead were measured at each facility. All eight samples taken at Lakewood exceeded the evaluation criteria of 0.05mg/m3 with the range being from 0.1 to 0.6mg/m3. Of 14 samples taken at Sparks, nine exceeded the criteria, ranging from 0.01 to 0.4...

Breathing zone and general room air concentrations of lead were measured at each facility. All eight samples taken at Lakewood exceeded the evaluation criteria of 0.05mg/m3 with the range being from 0.1 to 0.6mg/m3. Of 14 samples taken at Sparks, nine exceeded the criteria, ranging from 0.01 to 0.49mg/m3. Improvements were needed in the exhaust ventilation systems at each location. Medical evaluations of ten employees at Sparks showed blood lead levels within the OSHA regulatory limits. However, three workers were over 40 micrograms/deciliter, the limit for returning to a job that involves lead exposure. The authors conclude that a health hazard existed from over exposure to lead at these facilities. The authors recommend improvements in the ventilation system and an upgraded respirator program. All workers should be advised of the toxic properties of lead exposure. Workers in the assay department should shower and change clothes and shoes at the end of the day to prevent lead contamination from entering the home. Personal hygiene should be improved. Medical monitoring of workers should continue.

No exposure to butyl-cellosolve was detected among liquid coaters and no epichlorohydrin was detected in the process area air samples. No exposure to nickel or chromium was detected among mechanical grinding spirallers. One laser spiraller was exposed to 8 micrograms/cubic meter (microg/m3) of nickel and 8microg/m3 chromium. Trace amounts of nickel were noted in the breathing zones of one plating lab worker and one calibrator. Total particulate exposures ranged from 0.1 to 0.9mg/m3. The author concludes that there were no known overexposures to contaminants at this facility. The author recommends that the exhaust ducts and fan be checked to find the cause for decreased mixing room ventilation system performance noted at the time of the study. Mixing room workers should ensure that all materials are handled as closely as possible to the local exhaust hoods. Standard written operation procedures for use of respirators should be developed.

(1987) Federal Reserve Bank, Cincinnati, Ohio. (Click to open report) In response to a request from the Federal Reserve Bank (SIC-6011) located in Cincinnati, Ohio, an evaluation of airborne lead (7439921) exposures was made during the use of an indoor firing range. The range was used by about 20 bank guards who must qualify quarterly; range officers were rotated to reduce chronic exposures.

The range was used by about 20 bank guards who must qualify quarterly; range officers were rotated to reduce chronic exposures. Lead levels produced by the firing of two specific types of ammunition was also evaluated. In the four breathing zone air samples collected, the mean 8 hour time weighted average exposure to lead was 89 micrograms/cubic meter (microg/m3) when using standard lead ammunition (range 23 to 160microg/m3), and 79microg/m3 (range 50 to 120microg/m3) when firing copper coated lead bullets. In either case the lead level exceeded OSHA permissible exposure limit of 50microg/m3. During both evaluations the ventilation system at the range was performing poorly. Airflow was erratic and turbulent so that much of the air flowed backwards. The copper coating on the bullets was apparently too thin to do much to stop the lead from entering the atmosphere. The author concludes that a health hazard from overexposure to lead existed at the firing range. The author recommends that the the bullet trap exhaust be repaired, since no matter how much the air flow is increased in the range, the problem will not be solved until the lead is trapped in the exhaust. Until the ventilation is repaired, jacketed bullets should be used on this range.

(1987) Silver Deer Spectrum, Boulder, Colorado. (Click to open report) The management of the Silver Deer Spectrum (SIC-3229), Boulder, Colorado, requested an evaluation of exposures to lead (7439921), glues and solvents for workers involved in the grinding, polishing, gluing and silkscreening of leaded glass crystal art objects. Sixteen breathing zone and general room air samples were collected with lead concentrations ranging from not detectable to 0.08mg/m3. Three of these readings exceeded the evaluation criteria of action level for lead. Methylene-chloride (750...

Sixteen breathing zone and general room air samples were collected with lead concentrations ranging from not detectable to 0.08mg/m3. Three of these readings exceeded the evaluation criteria of action level for lead. Methylene-chloride (75092) was found in small quantities in 13 of 14 air samples. The highest level of methylene-chloride detected was 15.7mg/m3. No workers from the grinding room showed blood lead levels above 40 micrograms/deciliter. No evidence of lead toxicity was noted in workers from the blood samples or from discussions held with the workers. The author concludes that a potential health hazard from lead existed at the time of the evaluation. The author recommends that care be taken to reduce lead exposure in the grinding room. No dry grinding or polishing of the leaded glass should be permitted. The down draft ventilation in the grinding stations should be maintained, cleaned, and balanced so that each work station has sufficient capture velocity.

The hog fuel and waste fuel boilers were the areas of specific concern at this paper mill. Breathing zone samples collected for nine locations were found to be below the evaluation criteria for crystalline silica and total particulate contents. Respirable silica was present at 0.02mg/m3 at its highest concentration. Results of the bulk analyses showed that the workers were exposed to material containing only 3.1 percent quartz (14808607) and less than 0.75 percent cristobalite, suggesting no hazard from crystalline silica. Respirable particulate concentrations ranged from 0.2 to 11.0, with a average concentration of 4.12mg/m3. Lead and chromium (7440473) were below the detection limit. A bulk sample of gasket material was 50 to 60 percent chrysotile (12001295) asbestos. The author concludes that a potential health hazard existed from exposure to total dust in the boiler area, and from installation of asbestos gasket material. Workers involved in handling the gasket material should be advised that it is made of asbestos and to take the required safety precautions. The asbestos gasket material should be replaced by some less hazardous material.

(1986) City of Columbus Refuse Derived Fuel Power Plant, Columbus, Ohio. (Click to open report) As a result of a request from the City of Columbus, Ohio, potential for heat stress along with exposure to chemical contaminants and airborne microbial pollutants was investigated at the city refuse derived fuel powerplant (SIC-4931, SIC-4953). Health hazards existed from lead (7439921) and silica exposures for workers involved in handling ash. Low levels of exposure to chromium (7440473), chromium-VI, cadmium (7440439), and nickel (7440020) were noted. Excessive heat stress occurred during the ...

Health hazards existed from lead (7439921) and silica exposures for workers involved in handling ash. Low levels of exposure to chromium (7440473), chromium-VI, cadmium (7440439), and nickel (7440020) were noted. Excessive heat stress occurred during the maintenance activities in hot areas of the facility. Airborne microbial contamination levels in the refuse handling areas indicated that exposure hazards existed by both the inhalation and ingestion routes. Human pathogens may be present in the microbial pollutants. The author recommends that the use of engineering controls be instituted to lessen the exposure of employees to lead. In the power plant area and in the refuse handling area, eating, drinking, and the carrying or use of tobacco products or cosmetics should be prohibited. Use of dry sweeping or compressed air cleaning of surfaces to remove dust must be discontinued. Vacuuming or wet removal of dust particles should be used instead. At material transfer points, where dust exposure can be a real problem, it is recommended that enclosures be built. Single use disposable dust respirators are not recommended. Recommended methods for controlling heat stress include modification of environmental heat exchange components, work schedule modifications, protective clothing, worker education, and preplacement and periodic medical surveillance.

Total welding fume concentrations in 32 personal breathing zone samples ranged from 1.5 to 23.4 milligrams per cubic meter (mg/m3). Nine area samples ranged from 0.4 to 3.7mg/m3. Three sample results exceeded OSHA standard of 15mg/m3. Iron (7439896) was the predominant metal found. Measurable quantities of aluminum (7429905), chromium (7440473), copper (7440508), magnesium (7439954), manganese (7439965), molybdenum (7439987), nickel (7440020), lead (7439921), tin (7440315), and vanadium (7440622) were found. Results of a questionnaire, given to 33 of the 92 welders, indicated a relatively high prevalence of reported symptoms of mucous membrane and respiratory tract irritation, including eye irritation, sinus/nasal congestion, headaches, throat irritation and cough. Cigarette smoking was high among the welders, but symptoms could not be totally related to that cause. The authors conclude that welding fumes and paint vapors were potential health hazards and caused short term health effects. The authors recommend that welding fume exposures should be controlled by local ventilation where feasible. The use of respirators for protection against welding fumes should not be viewed as a long term control measure.

(SIC-3341), located in Fairfield, Connecticut. Granulomatous lung disease was present in five employees of the refinery, four of whom had worked in the furnace area. The investigation did result in the confirmation that a health hazard from beryllium exposure has existed at this facility. Four of the five cases were work related. Of 121 personal air samples, 114 exceeded the OSHA permissible exposure limit (PEL) for silver, 62 exceeded the NIOSH recommended exposure limit (REL) for beryllium, 55 exceeded the OSHA PEL for lead, 54 exceeded the NIOSH REL for nickel, and 6 exceeded the NIOSH REL for arsenic. Cadmium levels are to be maintained at the lowest feasible limit. The 39 personal air samples from the manufacturing melt area showed exposure to cadmium from 9.3 to 115 micrograms per cubic meter (microg/m3), and silver concentrations ranging from 11 to 104microg/m3. All of the silver concentrations exceeded the OSHA PEL. The authors conclude that a health hazard from beryllium exposure has and may still exist at this facility. Recommendations include the use of rubber gaskets on drums during blender and crusher unloading, redesign of ventilation hoods and their operation at sufficient velocity, the use of respirators in the melt room, and systematic medical examinations.

(SIC-3999), Boulder, Colorado, an evaluation of exposures to lead (7439921) in the copper and lead glazing art studio was carried out. Three workers were involved at the time, and the possibility of hiring more workers prompted the request. Breathing zone and general air samples were analyzed by NIOSH Method P and CAM 173, blood lead was measured by voltammetry, and free erythrocyte protoporphyrin was measured photofluorometrically. Average airborne lead concentration was 0.08mg/m3, and five of seven samples equaled or exceeded the OSHA time weighted average limit of 0.05mg/m3. Blood lead concentrations were 7, 16, and 33 micrograms/deciliter (microg/dl), which were all below the OSHA limit of 40microg/dl for returning to a job involving lead exposure. One free erythrocyte protoporphyrin sample was 59microg/dl, which was above the normal limit of 50microg/dl. Ventilation was found to be inadequate for removing airborne lead resulting from use of lead dust and furnaces. The author concludes that the high environmental lead levels present a health hazard, and recommends improved exhaust ventilation, continued use of ultra filter respiratory protection, and education of new employees on clean work habits.
