The demonstration took place in 172 vacant housing units in several different cities. The abatement methods used included abrasive removal, chemical removal, heat gun removal, encapsulation, enclosure, and replacement. Evaluations were made during the demonstrations and it was determined that the workers were exposed to lead (7439921) with the highest exposure levels coming during the heat gun method of removal. Exposures to volatile organic compounds were low. Maximum personal and general area airborne lead concentrations were 916 micrograms/cubic meter and 1296 micrograms/cubic meter, respectively. Soil sampling indicated that lead paint abatement in some cases resulted in increases in soil lead levels 1 to 3 feet from the exterior walls. The author concludes that workers were potentially overexposed to lead during lead abatement. The author recommend specific measures concerning training, work practices, engineering controls, safety programs, risk assessment, respiratory protection programs, medical monitoring and surveillance.

The requestors were concerned about exposures to lead (7439921) during handgun qualifying sessions and the possible health hazards associated with these exposures. Environmental samples were collected for airborne lead, surface lead, and hand lead contamination during a 70 minute handgun training activity. A ventilation survey was also conducted. Eight shooters and two range officers were exposed to airborne lead concentrations ranging from 132 to 254 micrograms per cubic meter of air. Lead levels on desk surfaces inside the range were as high as 10,330 micrograms/square meter. The ventilation study revealed back flow eddies throughout the range, especially at the firing line, indicating that the newly redesigned air handling system was not effectively removing lead. The authors conclude that a potential hazard from overexposure to lead via inhalation and ingestion existed at the firing range. There was a potential for para occupational exposure of family members. The authors recommend modifications to the ventilation system and other measures to reduce exposures.

About 200,000 rounds of ammunition are fired at the range each year. Personal breathing zone and area air samples were taken for lead analysis. Surface wipe samples were taken as well along with hand lead concentrations and contamination of clothing. Air sampling revealed that the officers were exposed to 8 hour time weighted average concentrations of airborne lead ranging from nondetectable to 8 micrograms (microg) per cubic meter. The general air samples collected ranged from nondetectable to trace levels of contamination. Wipe samples of several surfaces indicated lead contamination ranging from 1350 to 1180microg per square meter (m2). The officers' hands were contaminated with lead. Even after washing their hands, the concentrations ranged from 210 to 110microg/m2. One of six patches from a tee shirt worn by an officer showed lead at 110microg/gram of material. The authors conclude that airborne lead did not exceed evaluation criteria, but dermal, surface and clothing contamination could increase the potential for lead ingestion and lead contamination of automobiles and homes. The authors recommend that efforts be made to reduce the potential spread of lead, and that medical surveillance be instituted for frequent range users and the range master.

Twenty one to 23 workers at the facility were engaged in making jewelry; processes used included lost wax casting, resin molding, and soldering. Personal air sampling was conducted to evaluate employee exposure to carbon-monoxide (630080), crystalline silica (14808607) and metal fume in the Casting Department, styrene (100425) in the Gems by Jim Department, and toluene (108883) and xylene (1330207) in the Box Filler Department. The ventilation systems used for contaminant control were evaluated, informal interviews with employees were conducted, and chemical handling practices were observed. All exposures were below recommended levels for all tasks monitored. Although the levels of silver (7440224) were below the NIOSH recommended exposure limit of systems, installed to control worker exposure to contaminants, were based on inappropriate design criteria. The author concludes that the silver level is of concern. The author recommends that controls to reduce exposure to silver fume be implemented, that employee training and respiratory protection programs be implemented, and that the exhaust ventilation system be improved.

M and J Painting Company (SIC-1622) was responsible for removal of the existing lead (7439921) based paint and corrosion with abrasive blasting within containment structures. Six NIOSH visits were made to the site. Ranges for personal exposures to airborne lead were 3,690 to 29,400 micrograms/cubic meter (microg/m3) for abrasive blasters and 5 to 6720microg/m3 for other job categories. Respirators in use were not sufficiently protective. Personal exposure to noise expressed as 8 hour time weighted averages ranged from 89.6 decibels-A to 105.4 decibels-A. The mean blood lead level increased from 29 micrograms/deciliter to 36 micrograms/deciliter among eight workers after approximately 1 month of work on the bridge. The authors conclude that a health hazard existed during paint removal on the bridge due to overexposure to lead and noise. The authors recommend specific measures for reducing the lead and noise exposures including improved engineering controls, work practices, respiratory protection program and personal hygiene facilities.

Concern had been expressed regarding exposure to sulfur-dioxide (7446095), nitrogen oxides, inorganic acids, metals, dioxins, furans, and bacteria in the sludge dewatering and incineration buildings. There were approximately 60 employees on three shifts with the potential for exposure in the sewer sludge dewatering and incineration buildings. Personal breathing zone and area air samples were taken along with surface wipe and bulk materials samples. Contaminant concentrations did not exceed current environmental evaluation criteria for the substances investigated. Health complaints were not reported by employees at the time of the site visits. The authors conclude that concentrations of cadmium (7440439), chromium (7440473), lead (7439921), nickel (7440020), and quartz (14808607) in dewatered sludge and surface dusts represented potential ingestion and inhalation hazards. The authors recommend measures to prevent contact with contaminated materials.

The job at Eaton Metals involved the lining of two 85 foot long, 14.5 foot diameter steel tanks with lead sheets. All 22 employees on the day of the study provided blood specimens. The mean blood lead level was 23 micrograms/100 grams whole blood with a range of 4 to 38. No employee had creatinine (CR) levels above the normal range. Two employees had blood urea nitrogen (BUN) levels above the normal range. Time weighted average exposures for airborne lead ranged from 23 to 1790 micrograms/cubic meter of air; all but one were above the Utah OSHA permissible exposure limit (PEL) of 50 micrograms/cubic meter. The short term lead concentrations for the various jobs ranged from 53 to 450 micrograms/cubic meter. Wipe samples revealed the presence of lead contamination on table surfaces in the lunch room, on workers' clothes and shoes, in the workers' cars, and on the floor of the change room. The authors conclude that employee blood lead levels were reduced below the level requiring bimonthly testing. However, personal breathing zone lead levels were above the PEL and wipe samples still indicated lead contamination. The authors recommend that additional efforts be made to clean up lead contamination. Respirators should be stored in protective bags.

Full shift personal breathing zone and general area air samples were analyzed for polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), total dust, respirable dust, crystalline silica (14808607), and metals. Airborne concentrations of respirable nuisance dust were all well below the permissible exposure limits. Concentrations of PCDDs/PCDFs expressed as 2,3,7,8- tetrachloro-dibenzo-p-dioxin (1746016) (TCDD) equivalents ranged from 0.01 to 12.8 picograms per cubic meter. There was also significant lead (7439921) surface contamination in one wipe sample. The authors conclude that possible exposures to PCDDs/PCDFs via inhalation and from surface contamination did exist. The facility ceased operations immediately after the evaluation. The authors recommend measures to cut down on exposure should the site be reopened for use or remediation.

(SIC-1629). The requestor was concerned about possible hazardous exposures to lead (7439921). The 135 foot high elevated water storage tank had an estimated exterior surface area of 35,000 square feet. It had been painted with a red lead primer, and an alkyd lead based paint. During moving and set up of a primary containment structure, personal airborne lead exposures were below the OSHA Permissible Exposure Limit (PEL) of 50 micrograms/cubic meter (microg/m3). During abrasive blasting operations, levels outside the containment approached the PEL. Airborne lead concentrations in the containment ranged from 620 to 3000microg/m3. No workers had increased blood lead levels during the job. The authors conclude that a potential health hazard due to lead exposures existed during repainting of the structure; however, the worker protection program in place at the time of the study appeared to adequately protect the workers from the lead. The protection program was a comprehensive one which was in compliance with Maryland requirements.

The Mueller Company is a grey iron and brass foundry producing valves for water and gas distribution service. Formaldehyde levels of 0.32 to 0.65 parts per million were recorded. Three of seven readings exceeded the OSHA permissible exposure limit of 1 part per million. Respirable dust sampling measured 4.34mg/m3 in the breathing zone of the muller operator and 1.46mg/m3 at a location 10 feet from the front of the muller at breathing zone height. Silica (14808607) content in these samples was 60.2% and 50.0%, respectively. Exposure to cadmium (7440439), lead (7439921), and zinc (7440666) on the pour deck exceeded one or more of the evaluation criteria; appropriate respiratory protection was used by workers in this area. Symptoms reported by the workers included headache, sinus pain, nausea, and eye irritation. Silicosis was verified in one worker. Formaldehyde related dermatitis was diagnosed in another. The authors conclude that there was a hazard from exposures to formaldehyde and silica. The authors recommend specific measures to reduce these hazardous exposures.
