Anti-static abrasives help lower wood dust at the source.

While government, industry and union lawyers wrestle with the fallout from a federal court ruling that threw out an existing regulation covering wood dust exposure limits, woodworking companies must continue to control the amount of dust employees are exposed to under OSHA's general duty clause.

"...The OSHA general duty clause still will require employers to control worker exposure. As a matter of prudence, employers may want to follow the vacated standards (of 5mg/[m.sub.3]) voluntarily," said Katherine L. Rhyne, counsel for the Inter-Industry Wood Dust Coordinating committee, a coalition of industry associations.

One way woodworking companies can cut down on wood dust and work toward meeting this ambiguous clause is to remove more of the wood dust at the source, using an anti-static abrasive product.

"Static charges and flying dust cannot be eliminated entirely, but these new dust control abrasives can control them effectively when used with an efficient collection system," said Frank Obermeier of 3M's Industrial Abrasive Division.

Anti-static abrasives differ from standard abrasives in that a chemical has been added to the coating surface which neutralizes the wood dust produced in the sanding operation and helps prevent dust buildup. During a normal sanding operation, friction produces a negative charge on the workpiece, machine and operator and a positive charge on the wood dust, which results in an instant attraction. Antistatic abrasives neutralize the charges and allow the dust to remain suspended in the air for easier collection.

The following are some of the anti-static abrasives and other products available in the marketplace. For additional information see Chapter 7 of the 1992 Red Book.
