The device is constructed from three cells attached on one side to a flat indicator layer and on the other side to a series of different diffusive resistances. The third cell is connected to the diffusion path with length-of-stain properties. Acetone vapor diffuses to the cells through the different diffusive resistances and reacts with the indicator layer producing color change from yellow to pink. After saturation of the third cell, the color change creeps along the length-of-stain diffusion path producing a sharp diffusion front. The color produced on the indicator layer, as spots and length-of-stain, is a direct measure of the exposure dose. Visual color comparison is achieved by: (1) observing the formation of the pink threshold color on the individual cell and reading the corresponding exposure dose, or (2) for doses exceeding 1,500 ppm•hr reading the length-of-pink-stain from the scale. Acetone is a colorless liquid with a sharp specific odor (the odor threshold is 4 ppb). It is narcotic in mild concentrations with toxic effects on the central nervous system. Chronic exposure causes mucous membrane irritation, heavy eyes and overnight headache. Acetone is a cumulative poison and can be found in the blood long after exposure. OSHA PEL (permissible exposure limit) for general industry is 1,000 ppm (TWA). NIOSH REL (recommended exposure limit) for acetone is 250 ppm (TWA). *May also be used to monitor for methyl ethyl ketone (MEK) and methyl isobutyl ketone (MIBK) by applying a multiplication factor.
