The evaluation was requested by the Chief of Police on behalf of about 120 Division officers and 8 or 9 range officers. Personal samples for shooters contained 1,000 to 6,400 micrograms per cubic meter (micrograms/Cu m) of lead during firing. Personal samples for range officers contained 560 to 3,000 micrograms/Cu m of lead during combat firing and 600 micrograms/Cu m during bullseye firing. Area air samples ranged from 400 to 37,000 micrograms/Cu m of lead during firing and from 100 to 2,000 micrograms/Cu m during the first half hour after firing ceased. Average air velocity across shooting positions ranged from 20 to 50 feet per minute, for an air supply of 1,200 cubic feet per minute (cfm) to the firing line and air exhaust of 3800cfm from the range. The investigators note that the OSHA standard for inorganic lead is an 8 hour time weighted average concentration of 200 micrograms/Cu m. They concluded that range officers were exposed to excessive lead concentrations. They recommend changes in design considerations and work practices to reduce lead concentrations in indoor firing ranges.

Most of the 20 workers in these areas also were interviewed and monitored for possible lead exposure. The evaluation resulted from a request to NIOSH from company management. Breathing zone and general air samples were taken on AA filters using vacuum pumps. Samples were analyzed using atomic absorption techniques. The highest concentration of airborne lead observed (0.02 milligrams of substance per cubic meter of air) was less than the OSHA standard of 0.05 milligrams. Results of employee interviews and a review of the physical conditions of the workplace also revealed no health hazards. It is recommended that the workers continue the practice of washing their hands before eating and that no eating, drinking, or smoking be allowed at the work station.

The survey was requested by the Forest Service to determine worker exposure to elements of tree marking paint. Personal air samples were analyzed for inorganic lead (7439921) and hexavalent chromium (18540299) content. Concentrations of both substances were undetectable and consequently, below the OSHA standards of 50 micrograms per cubic meter of air for lead, and 200 micrograms per cubic meter of air for hexavalent chromium. The results indicate that no exposure hazard existed, probably because these chemicals are applied in outdoor, well ventilated settings. Recommendations resulting from the survey advise the prudent use of cleaning solvents, adherence to good personal hygiene habits, and wearing of protective clothing.

Sampling was in response to a request by company officials to evaluate the exposure of surface weld shop workers to hazardous materials. Except for lead, all substance levels were below evaluation criteria; and all urinary concentrations were within normal limits. Two of 11 lead samples (0.09 and 0.11 milligrams of substance per cubic meter or air) exceeded and 2 other samples were equivalent to the OSHA standard for lead of 0.05 milligrams of substance per cubic meter of air. It is concluded that proper protective measures should be taken when welding and cutting previously painted metal surfaces and work procedures for use of the degreasing tank should be improved. It is recommended that a substitute be found for the use of lead base paint and that a preoperation be done to remove the lead base paint from the welding area. Local exhaust ventilation should be provided in the welding shop. Ventilation also should be provided when welding in a confined area, along with a NIOSH/Mining Safety Health Administration approved airline respirator for fumes. Gloves that are resistant to methyl-chloroform (71556) should be worn when using the degreasing tank, and the tank should be covered with a tight fitting lid when it is not in use.

An evaluation request came from an authorized representative of an unspecified number of workers using a trademarked painting system (Centauri). Four of the 11 air lead (7439921) samples of 300, 380, 540, and 1,600 micrograms per cubic meter (micrograms/cu m) exceeded the OSHA standard of 200 micrograms/cu m for an 8 hour time weighted average. One sample of hexamethylene-diisocyanate (822060) (HDI) in the cab spray booth measured 192.5 micrograms/cu m. Solvent exposures to toluene (108883), xylene (1330207), and naphtha (8030306) were well below OSHA standards of 750 milligrams per cubic meter (mg/cu m) time weighted average, 435mg/cu m time weighted average and 400mg/cu m, respectively. Medical and environmental findings indicated repeated overexposure to HDI, and one worker had become sensitized. The author concludes that a potential health hazard exists for the workers exposed to Centauri paint and recommends that measures to control lead exposure be implemented, HDI exposure be minimized through improved respiratory protection, a less hazardous process material be substituted and some processes be automated and ventilation be improved.

(1978) A study of the effectiveness of copper jacketed ammunition in lowering lead exposures in indoor firing ranges. (Click to open report) Lead (7439921) exposure at two United States Postal Services indoor firing ranges was examined. The study was conducted on February 16 and 17, 1976 following a request by the Chief Postal Inspector. The purpose of the study was to determine whether the use of cartridges containing copper (7440508) coated slugs would lower air lead concentrations. Air lead concentrations varied from 0.18 to 0.69 milligrams per cubic meter (mg/m3) with a mean of 0.34mg/m3 for the copper coated bullets. For lead bu...

The purpose of the study was to determine whether the use of cartridges containing copper (7440508) coated slugs would lower air lead concentrations. Air lead concentrations varied from 0.18 to 0.69 milligrams per cubic meter (mg/m3) with a mean of 0.34mg/m3 for the copper coated bullets. For lead bullets, lead concentrations varied between 0.33 and 1.02mg/m3 with a mean of 0.55mg/m3. At the other range, air lead values ranged from 1.3 to 1.9mg/m3 with a mean of 1.5mg/m3 for the copper and 0.84 to 2.20mg/m3 with a mean of 1.3mg/m3 for the lead bullets. The OSHA standard for lead exposure was 0.20mg/m3. On the basis of this standard, the author concludes that a significant lead exposure hazard existed even with the use of the copper coated cartridges. This hazard is particularly threatening to the range supervisors. The author recommends that the Postal Service continue with its plan to install a new ventilation system.

(SIC-3325) in Tacoma, Washington in November 1977. An employee representative of the United Steel Workers Local 25, Tacoma, Washington requested toxicity determination on behalf of approximately 135 affected workers. Hematocrits ranged from 42 to 51 percent. Blood lead concentrations ranged from 16 to 41 micrograms per deciliter. Only one worker had an abnormally high FEP value of 197. In the roaster area, 37 of 44 time weighted average (TWA) As samples exceeded the OSHA criterion of 0.01 milligrams per cubic meter (mg/m3) and 3 of 36 TWA Cu samples exceeded the OSHA criterion of 1mg/m3. Seventeen of 21 As samples from the reverberatory furnace, 20 of 20 from the convertor area, and 3 of 7 from the slimes house also exceeded the OSHA standard. Six of 36 Pb samples from the convertor area and 1 of 2 from the slimes house also exceeded the OSHA criterion of 0.2mg/m3. In the sulfur dioxide area, 2 of 2 As samples and 1 of 2 Pb samples exceeded the respective OSHA standard. The authors recommend that worker exposures to toxic substance be reduced below the OSHa criteria, and that appropriate NIOSH approved respirators be used. The action level for blood lead concentrations should be reduced from 80 to 40 micrograms per deciliter.
