Abstract
An industrial hygiene survey was conducted in three Forest Ranger Districts of the Mark Twain National Forest (SIC-0851) in Missouri from April 23 to 27, 1979. 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.
