A single ripping cut with a thin kerf blade of 5/4 oak plank 8' long will create 10 grams of <15 micron dust. If distributed evenly throughout the shop, this would create a dust concentration of 9.1 mg/m**3, much greater than the ACGIH hardwood limit of 1.0 mg/m**3. In addition, fine dust is difficult to remove. When it finally settles, sweeping causes much of the dust to again become airborne. Vacuuming is only effective when using a fine filter. So the fine dust tends to accumulate, bringing the airborne dust levels higher and higher.
