Part C-1 requires employers to provide and enforce the use of fall protection for employees performing activities covered under chapter 296-155 WAC, Safety Standards for Construction.
Affected area is the
distance away from the edge of an excavation equal to the depth of the excavation up to a maximum distance of 15ft. For example, an excavation 10 ft. deep has an affected area extending 10 ft. from the edge of any side of the excavation.
Catch platform is a type of fall arrest system that consists of a platform installed within four vertical feet of the fall hazard, is at least forty-five inches wide and is equipped with a standard guardrail system on all exposed sides.
Equivalent means alternative designs, materials, or methods to
protect against a hazard which the employer can demonstrate and will provide an equal or greater degree of safety for employees than the methods, materials or designs specified in this standard.
Floor hole is an opening measuring less than 12 in. but more than 1 in. in its least dimension in any floor, roof, platform, or surface through which materials but not persons may fall, such as a belt hole, pipe opening, or slot opening.
Walking/working surface means any area including, but not limited to, floors, a roof surface, bridge, the ground, and any other surfaces whose dimensions are forty-five inches or more in all directions, through which workers can pass or conduct work. A walking /working surface does not include vehicles or rolling stock on which employees must be located in order to perform their job duties.
Floor opening means an opening measuring 12 in. or more in its least dimension in any floor, roof, platform, or surface through which persons may fall.
Hazardous slope is a slope where normal footing cannot be maintained without the use of devices due to the pitch of the
surface, weather conditions, or surface material.
Safety watch system means a fall protection system as described in WAC 296-155-24615(6), in which a competent person monitors one worker who is engaged in repair work or servicing equipment on low pitch roofs only.
Fall hazards can occur at any level. There are three threshold levels which have fall hazard concerns and requirements:
Fall hazards on walking/working surfaces, with open sides, wall openings, ramps, or runways. It also includes work on steep pitch roofs, hazardous slopes, etc.
Fall hazards when working above or adjacent to dangerous equipment; floor holes/openings into which persons can walk; and impalement hazards.
Fall hazards during leading edge and roofing work on low pitched surfaces, excavation work, or any other working surface that is not a walking/working surface, such as beams, the sides of structures, etc.
WA State Requires Fall Protection at 4 ft. or more for Construction
Exceptions to the 4 ft. rule (Based on certain hazards)
Exemptions from the 4 ft. rule (Based on certain activities)
Working above or adjacent to dangerous equipment
Roofing work & leading edge work on a low pitch surface
Employees exposed to these hazards must be protected from falls regardless of height
Employees engaged in these activities must be protected from falls of 10’ or more
Working on any surface that does not meet the definition of a walking/working surface
Floor holes/openings into which persons can accidentally walk
Trenching and Excavation
(see note below)
Exception: fall protection is not required for persons directly involved in the excavation process (foreman; signal person; employee hooking on pipe or other material; grade person; state, county, or city inspectors; engineer or other professional conducting a QA inspection)
