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 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 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.

The evaluation was requested by the Business Representative for the Chicago Web Pressmans Union Number 7 on behalf of 350 pressmen, Junior Pressmen, and Apprentice Pressmen working in the pressroom. Many of the complaints and health problems reported by employees were not associated with ink mist exposure. One personal sample exceeded the OSHA standard of 5 milligrams per cubic meter (mg/m3) for ink mist. Oil mist combined with ink mist during roller lubrication generated excessive mist exposure for the pressman. Airborne trace metals were below hazardous concentrations. Atmospheric sampling and analysis of black ink did not reveal the presence of polynuclear aromatic hydrocarbons. Benzidine (92875) and 3,3'-dichlorobenzidine (91941) were not detected in the atmospheric yellow ink mist samples. The concentration and composition of the airborne paper dust was not considered hazardous. The author concludes that inhalation of ink mist and paper dust at the concentrations found in the pressroom did not pose a health hazard at the time of the surveys. Precautions should be taken to minimize exposure of the pressmen to ink mist generated by operating presses, pressmen should wear the disposable single use mist masks when servicing operating printing units, that pressmen who come in contact with inks should be instructed to wash their hands before smoking or eating, kerosene should be stored in fire resistant safety containers with self closing lids, and cleanup personnel should be provided with protective clothing.

The evaluation was requested by an authorized employee representative on behalf of the 300 affected employees. Carbon-monoxide (630080) concentrations ranged from 41 to 118 parts per million (ppm) for short term detectors and from 25 to 106ppm for long term detectors, exceeding the 50ppm OSHA standard. Chlorodifluoromethane (75456) (Freon-22) concentrations ranged from 2,906 to 3,146ppm, exceeding the American Conference of Governmental Industrial Hygienist standard of 1,000ppm. All other environmental samples were below their respective criteria. The author concludes that workers are exposed to hazardous concentrations of carbon-monoxide. The Freon-22 concentrations present a potential exposure hazard. The author recommends that exposure to carbon-monoxide be reduced through conversion of gasoline powered lift trucks to low pressure gas or the use of catalytic converters, that the ventilation system be modified, that an exhaust ventilation system be completed at the bottled gas filling apparatus, and that present exhaust ventilation systems be changed.
