Falls are the most frequent cause of fatalities in construction and annually account for one of every three construction-related deaths. Fall protection trigger heights will vary depending on the task being performed. The “trigger height” is the minimum height at which fall protection is required. Know the trigger heights for your work and use fall protection as required.
Fall protection Required Regardless of Height
- Open sided floors, walkways, platforms, or runways above or adjacent to dangerous equipment.
- Floor holes or floor openings into which persons can accidentally walk.
- Falls into or onto impalement hazards, such as reinforcing steel (rebar), or exposed steel or wood stakes used to set forms.
- Working from boom supported elevated work platforms. WAC 296-869-20045
- Working in confined spaces. WAC 296-809-60004
Fall Protection at Four Feet or More
- When employees are exposed to fall hazards of four feet or more to the ground or lower level when on a walking/working surface.
- Walking/working surface is any area whose dimensions are 45 inches or greater in all directions, through which workers pass or conduct work.
- When employees are using stilts
- Where employees are working on platforms above the protection of a guardrail system,
- While placing or tying reinforcing steel on a vertical face.
- While working on a roof with a pitch greater than four in twelve (4:12)
- While engaged in work, other than roofing work or leading edge work, on low pitched roofs
- While working on a hazardous slope
Fall Protection at Ten Feet or More
- WAC 296-155-24611

Understanding the type of work, the working surface, the fall distance and trigger heights will help in the selection of the right fall protection system.
