In response to a request from an industrial hygiene technician with the Walter Reed Army Medical Center, an investigation was made of possible hazardous working conditions at the Caisson Platoon (SIC- in ceremonies. Specific concern was expressed about exposure of soldiers to air contaminants while cleaning the stables, levelling the grain bin, and working in the tack room. Exposures experienced by blacksmiths in the execution of their duties were also monitored. The author concludes that soldiers dyeing leather in the tack room were exposed to methylene-chloride (75092) and 2-ethoxyethanol (110805) above the NIOSH recommended exposure limits. Soldiers cleaning the stables were not overexposed to nuisance dust or endotoxin. Soldiers involved in levelling grain in the grain bin were exposed to grain dust for a brief period of nearly 7 times the 8 hour recommended exposure limit of 4mg/m3. The exposures in the tack room could be reduced through the substitution of less hazardous ingredients in leather dyes, lacquers, and spray paints or through the use of local exhaust ventilation. The grain dust exposure can be controlled through the use of engineering controls, such as a vibratory shaker applied to the outside of the bin thus eliminating the need to enter the grain bin to level the grain. Local exhaust ventilation should be provided for welding operations in the blacksmith shop.
