BATON ROUQE, LA 70B20 DOW CHEMICAL Plaquemine, LA May 15, 1992 Six (6) filter cassette samples were received on May 13, 1992 from Dow Chemical for fiber count. Fibers larger than 5 microns in length were counted by means of phase-contrast microscopy at a magnification of 400X. The procedure recommended by NIOSH method 7400A was followed. Pertinent information regarding fiber counts is as follows: Field Area: 0.00785 ram2 (Walton Beckett Graticule) Effective Collecting Area: 385 mm2 (25 mm Cassette) 855 mm2 (37 mm Cassette) Limit of Quantitation: 10 fibers/100 fields Limit of Detection: > Average Blank Count @ Detection limits are based upon a minimal concentration of 7 fibers/mm2.
