WAC 296-806-20056. Make sure safeguarding by distance meets these requirements

You must make sure means used to safeguard by distance do both of the following: (1) Prevent parts or material from falling on employees below; and (2) Separate employees on fixed ladders, stairs, floors, or other walking or working surfaces from the hazard by: (a) More than seven feet vertically; or (b) A horizontal distance that prevents employees from contacting or being injured by the hazard according to the distances in Table 200-2. Table 200-2 helps you identify either the required horizontal distance from the hazard to the barricade (B), or the required height of the barricade (C), as long as you know A and either variable, B or C.

If a hazard involves flying chips, fluids, parts or materials, the barrier height, distance, and construction may need to be adjusted to provide adequate protection. Illustration 2 - How to measure variables for Table 2 Examples: (1) If the height of the hazard (A) is seventy-eight inches, and the horizontal distance from the hazard to the barricade (B) is fourteen inches, the required height of the barricade (C) is seventy-eight inches. (2) If the height of the hazard (A) is eighty-six inches, and the height of the barricade (C) is fifty-five inches, then the required horizontal distance from the hazard to the barricade (B) is twenty inches.
