Machine guarding - Washington

Washington’s state requirements regarding machine guarding include a substantial amount of regulation information beyond the federal requirements. A summary of the additional requirements includes the following:

• Unlike federal OSHA, WAC 296-806-20002 contains an exemption to the requirement for ensuring that machines are secured and do not move or change position during use.
• WAC 296-806-20018 adds requirements beyond federal OSHA for hand feeding and retrieval tools.
• WAC 296-806-20030 through WAC 296-806-20040 require protection beyond federal OSHA, specifically for shear points, revolving parts, reciprocating or other moving parts, flying fluids, falling objects, and moving surfaces with sharp edges, burrs, and protruding nails and bolts. However, WAC 296-806-20030 through WAC 296-806-20040 does not mention guillotine cutters, alligator shears, power presses, milling machines, power saws, jointers, portable power tools, and forming rolls and calendars, as federal OSHA does.
• WAC 296-806-20042 contains safeguarding methods that go beyond federal OSHA. In addition, the table of guard opening sizes (Table 200-1) at WAC 296-806-20042 differs from OSHA’s guard opening requirements.
• WAC 296-806-30016 adds exemptions for guarding fans beyond federal OSHA.
• WAC 296-806-30016 also requires employers to prevent rods, pipes, or other material being handled by workers from contacting moving fan blades.
• The following federal OSHA terms are missing from WAC 296-806-500: automatic feeding, belts, bite, block, bolt-headers, brake monitor, calendar, certification or certify, certification/validation, certify/validate, die builder, die set, direct drive, ejector, exposed to contact, foot control, foot pedal, fixed barrier guard, flywheels, forging rolls, gravity hammers, hand feeding tool, high-energy-rate forging machines, inorganic wheels, knockout, liftout, maintenance runway, mill, open framehammers (or blacksmith hammers), operator station, organic wheels, press, prime movers, ring rolls, safety system, semiautomatic feeding, sheaves, single stroke, stop control, stroking selector, and validation or validate.

• The following WAC 296-806-500 terms are defined differently from the corresponding federal OSHA terms: cutting-off wheels, die or dies, flanges, guard, slide, type 1 wheel, type 2 wheel, type 6 wheel, type 11 wheel, modified types 6 and 11 wheels (terrazzo), types 27 and 28 depressed center wheels, type 27A cutting-off wheel, flanges, inch, and slide.

Note: J. J. Keller and Associates has only compared 29 CFR 1910.211 and 1910.212 to WAC 296-806-20002, 20018, 20028, 20030, 20032, 20036, 20042, 30016, 30028, and 500. The remainder of WAC 296-806 does not compare to 29 CFR 1910.211 and 1910.212, but may go beyond OSHA requirements found in 29 CFR 1910 Subpart O, Machinery and Machine Guarding.
