It was originally requested by Mr. Lewis Wawro, .superintendent of manufacturing. Printed circuit boards reinforced w i t h f i b r o u s glass' and impregnated with epoxy resin or reinforced with alpha cellulose-type paper and impreg nated with epoxy resin were drilled on single spindle and on multiple spindle drill presses. One single spindle press was equipped with a dust collector but the operator did not use it."' The other presses had an air jet which removed chips from the drill. These'drills`varied in size from O.Oh inch to 0.10 inch. Drilling was not continuous as it was necessary to remove boards and replace with other ones to be drilled and occasionally to sharpen drills. V \ -'-"-S' ' , ' ' _ Atmospheric sauries were collected on pre-weighed membrane filters and final weight was determined in terms of fibrous glass dust. The samples collected represent exposures less than the tentative threshold limit value of 5 milligrams per1cubic meter of air. This room is to be enclosed and a n air conditioner installed probably during the early part of 1967. No difficulty has been experienced with dermatitis. .
