Common Units Used In Measuring Airborns Asbestos Concentrations Length 1 meter (m) = 39.37 inches or 3.28 feet 100 centimeters (cm) = 1 meter 1.000.000 micrometers (pm) * 1 meter Volume X~7 1.000,000 cm5 1 m5 1.000 cm3 = 1 liter V_______ 1 cubic m (m3) Weight (mess) 454 grams (g) 1 pound - 1,000.000.000 nenogrsms (ng) * 1 gram -............ Concentration (mass contained in a stated volume) 2 fibers per cm3 (the current 8*hour OSHA industrial standard) means that 2 fibers are present in each cm3 of air. Since there are 1.000.000cm3 in 1 m3, there would be 2,000,000 fibers in a m3. If each fiber is chrysotile asbestos (density of 0.0026 ng/pm3) and is just long and thick enough to be detected by the NIOSH procedure for determining compliance with the OSHA standard (5 pm in length and 0.3 pm in diameter), it would weight 0.0092 ng: Mass * rr/4 (diameter)3 (length) (density) it/4 (0.0 pm)3 (8 pm) (0.0026 ng/pm3) * 0.0092 ng A total of 2,000,000 of these fibers would weigh about 1,800 ng. Since the fibers in the above example are the smallest (shortest and thinnest) counted by the NIOSH procedure, fibers actually measured using this protocol are typically larger and thus weigh more. Comparison of fibers in this example with those actually measured is further complicated since nonasbestos as well as asbestos fibers are counted by the NIOSH protocol. As noted in the footnote to Figure 1, comparisons of total fibers counted with the mass of DUP 0917636 B-l DU 031306 asbestos measured in air sample* indicate that, on an average, about 30 fiber* counted by the NIOSH procedures equal one nanogram of asbestos. This relationship applies to samples collected during the spray application of asbeatos insulation. For these samples, each fiber counted weighs an average of 0.033 ng, or about 37 times more than those in the examola and 2.000,000 of them would weigh about 67,000 ng. DUP 0917637 8-2 031^01
