Does Oregon OSHA require that a partially exposed shaft on a motor - such as the one in this picture - be completely enclosed with a guard? The gap is too small for a person's fingers to contact the spinning shaft.

The entire shaft must be guarded. Even if the gap is too small for a person’s fingers to contact the shaft‚ loose clothing‚ lanyards for identification badges‚ or long hair could get caught.

The rule that applies in this case says:

“All exposed parts of horizontal shafting 7 feet or less from floor or working platform‚ excepting runways used exclusively for oiling, or running adjustments‚ shall be protected by a stationary casing enclosing shafting completely or by a trough enclosing sides and top or sides and bottom of shafting as location requires.”

You will find the rule in Division 2‚ Subdivision O‚ Machinery & Machine Guarding: 1910.219(c)(2)(i)‚ (Guarding horizontal shafting).
