Health Hazard Evaluations (HHEs)

(1975) H. C. Smith Company, Minot, North Dakota. (Click to open report)
Based on the results of both medical and environmental evaluations, a potentially toxic condition is judged to exist for construction workers from occupational exposures to lead (7439921), cadmium (7440439), and iron-oxide (1332372) fumes at seven missile silo sites (SIC-3443) in the Minot, North Dakota area. Protective measures suggested include biologic surveillance every three months, limitation of employee exposure, provision of protective clothing and airline respirators, and prohibition of...

Protective measures suggested include biologic surveillance every three months, limitation of employee exposure, provision of protective clothing and airline respirators, and prohibition of smoking.

(1975) National Lead Industries, Inc., Rowley, Utah. (Click to open report)
Breathing zone samples for chlorine were taken in a plant extracting magnesium (7439954) from brine (SIC-2819) from the Great Salt Lake. A health hazard was documented due to excessive worker exposure to chlorine (7782505) gas in the reactor building and the electrolytic cell building. Confidential employee interviews document this hazard since many of the workers showed symptoms of overexposure to chlorine gas.

Workers involved in the manufacture of refuse handling equipment and truck equipment are found to be exposed to potentially toxic concentrations of lead (7439921) in association with spray painting operations and welding emissions during cold weather. Concentrations of xylene (1330207) and chromium (7440473) measured in spray painting operations are not expected to produce adverse health effects.

Evaluation of exposures to mottle dust, lead (7439921), and asbestos (1332214) in the mottle area of floor tile production indicates that toxic levels of the substances are not present. Recommendations are given regarding a medical monitoring program, and the use of air hoses for cleaning work areas and equipment.

(1974) Docutel Corporation, Irving, Texas. (Click to open report)
A health hazard evaluation of Docutel Corporation in Irving, Texas, was performed in January and April, 1974. Potential hazardous exposure to metallic grinding dust, soldering fluid, petroleum oil fluid, cadmium (7440439) fumes, and welding fumes were examined. The three facilities of the company included an abrasive finishing operation (SIC-3291), manufacture of printed circuit boards (SIC- 3674), and the manufacture of automated bank and baggage handling systems.

Potential hazardous exposure to metallic grinding dust, soldering fluid, petroleum oil fluid, cadmium (7440439) fumes, and welding fumes were examined. The three facilities of the company included an abrasive finishing operation (SIC-3291), manufacture of printed circuit boards (SIC- 3674), and the manufacture of automated bank and baggage handling systems. There were about 250 workers involved. Environmental samples were analyzed for cadmium, lead (7439921), tin (7440315), manganese (7439965), and methyl-chloroform (71556). Medical examinations were performed. Methyl-chloroform concentrations ranged from 12 to 18 parts per million (ppm), well below the American Conference of Governmental Industrial Hygienists criteria value of 350ppm for an 8 hour exposure. Iron concentrations ranged from 0.01 to 0.47 milligrams per cubic meter (mg/m3), less than the criteria value of 10mg/m3. Cadmium concentrations were less than 0.01mg/m3. Lead concentrations were below 0.02mg/m3. Manganese ranged from values of the latter four chemicals were well below criteria values. Workers in the soldering area complained of nasal irritations. The authors conclude that no health hazard currently exists at the facilities. Recommendations include preplacement and periodic physical examinations, provision of gloves and safety glasses for the workers handling solvents, and regular environmental monitoring of the automatic soldering machine and degreaser.
