Washington Fall Protection Requirements
Washington runs its own OSHA-approved State Plan; state rules apply and may be stricter than federal. Washington requires fall protection at 4 feet in construction, lower than the federal 6 feet, under the Unified Fall Protection Rule (WAC 296-880). Steep roofs over 4:12 may not use warning-line or safety-monitor systems.

Official page ›Washington requirements beyond the baseline
Washington enforces fall protection through the Department of Labor & Industries Division of Occupational Safety and Health (DOSH) under WISHA. In 2020 the state consolidated its rules into a single chapter, WAC 296-880, the Unified Safety Standards for Fall Protection. The chapter applies across industries, and its 4 foot trigger reaches construction work that would be legal bare-edged under federal OSHA.
| Citation (WAC 296-880) | What it requires |
|---|---|
| WAC 296-880-20005 | The 4 foot rule. Fall protection is required at 4 feet or more on any walking or working surface with an unprotected side or edge, in construction and every other industry. On steep roofs over 4:12, only fall restraint, personal fall arrest, or positioning devices are allowed; warning lines and safety monitors are prohibited on any roof steeper than 4:12. |
| WAC 296-880-10020 | A written, site-specific fall protection work plan is required before anyone is exposed to a fall hazard of 10 feet or more, unless guardrails eliminate the hazard. It must identify the hazards, describe the systems, cover rescue, and be available on site, and workers must be trained on its contents. |
| WAC 296-880-30005 | Construction-specific triggers layered on the 4 foot rule: 6 feet for roofing work on low-pitch roofs and for building a leading edge, and 10 feet for erection or placement of structural members and for excavation and trenching exposure. |
| WAC 296-880-10010 | No minimum height for three hazards: open-sided surfaces above or next to dangerous equipment, holes a worker can trip on or step through, and impalement hazards such as exposed rebar. |
| WAC 296-880-10015 | Documented training is required for every exposed employee: names, dates, subjects, and the trainer signature, kept available for L&I inspectors. Retraining is required when conditions change or habits show the training did not stick. |
| WAC 296-880-20010 | Roof assessment exemption. Inspecting, investigating, or assessing conditions on a low-pitch roof before work starts or after it ends is exempt from the 4 foot rule, and so is installing or removing the anchor itself. The exemption never applies on steep-pitch roofs or once construction work is underway. |
| WAC 296-880-40020 | Fall arrest anchorages must support 5,000 pounds per attached worker, or 3,000 pounds when paired with a self-retracting lifeline limiting free fall to 2 feet or less, or be engineered with a 2:1 safety factor under a qualified person. Free fall is capped at 6 feet and arrest force at 1,800 pounds. |
| WAC 296-880-40025 | Fall restraint requires a full body harness rigged so the worker cannot reach the edge, and restraint anchorage points must support four times the intended load. |
| WAC 296-880-40005 | Guardrail specs are written directly into the rule text: top rail 39 to 45 inches above the surface with a midrail halfway down, built to hold a 200 pound load applied within 2 inches of the top edge without deflecting below 39 inches. The load numbers mirror federal 1926.502(b), but the member sizes are mandatory rule text in Washington rather than appendix guidance: 2x4 wood posts and top rail on 8 foot centers with a 1x6 midrail, 1 1/2 inch nominal pipe, or 2x2x3/8 inch steel angle. Wire rope guardrails must be stretched taut, stay between 39 and 45 inches at all points, and be flagged with high visibility material every 6 feet. Toeboards need at least 3 1/2 inches of height with no more than 1/4 inch of clearance at the surface. |
| WAC 296-880-10005 | Verify surfaces are structurally sound before anyone works on them, inspect personal fall protection before each use, and plan for prompt rescue of a fallen worker or assure self-rescue capability. |
Equipment and anchorage requirements
Anchorages for personal fall arrest must support 5,000 pounds per attached worker or be engineered with a 2:1 safety factor under 29 CFR 1926.502(d)(15). Guardrails carry the 42 inch, 200 pound rules of 1926.502(b), and equipment is certified to ANSI Z359. Every anchor, harness, and SRL we sell publishes its tested strength on the spec sheet.
Penalties
| Violation type | Maximum |
|---|---|
| Serious | $16,550 |

Washington fall protection FAQ
Who enforces fall protection in Washington?
WA Dept. of Labor & Industries (L&I / DOSH). Washington runs its own OSHA-approved State Plan; state rules apply and may be stricter than federal. Washington requires fall protection at 4 feet in construction, lower than the federal 6 feet, under the Unified Fall Protection Rule (WAC 296-880). Steep roofs over 4:12 may not use warning-line or safety-monitor systems.
At what height is fall protection required in Washington?
For construction, 4 ft under WAC 296-880. For general industry, 4 ft under WAC 296-880.
What are the maximum penalties in Washington?
Serious: $16,550; Willful or Repeat: $165,514. Confirm current amounts with the regulator.
How do I report a serious injury in Washington?
Call 1-800-423-7233. Washington requires reporting a fatality and an in-patient hospitalization within 8 hours, stricter than the federal 24-hour hospitalization window. Call 911 first in an emergency.
Can I use a safety monitor or warning line on a steep roof in Washington?
No. On any roof steeper than 4:12, both are prohibited. At 4 feet or more on a steep-pitch roof, your only options are personal fall restraint, personal fall arrest, or a positioning device system (WAC 296-880-20005). Safety monitoring survives only for roofing work on low-pitch roofs.
When do I need a written fall protection work plan in Washington?
Any time workers will be exposed to fall hazards of 10 feet or more, before they are exposed. The plan must be site specific, kept on site, and cover rescue, and workers must be trained on its contents. The only exception is guardrails that eliminate the hazard (WAC 296-880-10020).

At what height does OSHA require fall protection in construction?
Six feet above a lower level, under 29 CFR 1926.501(b)(1). General industry workplaces trigger at 4 feet under 1910.28, shipyards at 5 feet, and longshoring at 8 feet. Two common construction exceptions: scaffolds trigger at 10 feet under Subpart L, and fixed ladders require protection when the climb reaches 24 feet. Working above dangerous equipment requires protection at any height.
Is there a rule that lets me skip fall protection if I stay 6 feet from the edge?
No. Federal OSHA has no safe-distance exemption for construction work. Six feet is the height that triggers the duty, not a buffer zone on the roof. The closest thing in the standard is the warning line system for low-slope roofing work under 1926.502(f), which must be rigged at least 6 feet from the edge (10 feet when mechanical equipment is in use) and only works in the specific combinations 1926.501(b)(10) allows.
Do I need fall protection on a residential roof?
Yes. Under 1926.501(b)(13), anyone doing residential construction 6 feet or more above a lower level needs guardrails, safety nets, or a personal fall arrest system. If the employer can demonstrate those are infeasible or create a greater hazard, the only alternative is a written, site-specific fall protection plan that meets every requirement of 1926.502(k), which includes a qualified person preparing it and a competent person supervising it.
What does OSHA require for an anchor point?
An anchorage for personal fall arrest must support at least 5,000 pounds per worker attached, or be designed, installed, and used under the supervision of a qualified person as part of a complete system that maintains a safety factor of at least two. That is 1926.502(d)(15). Anchorages must also be independent of any anchorage used to support or suspend platforms.
How high does a guardrail have to be?
The top rail must be 42 inches above the walking or working level, plus or minus 3 inches, and it must withstand 200 pounds of outward or downward force under 1926.502(b). Midrails go at 21 inches and must take 150 pounds. When guardrails protect a hole, they go on all unprotected sides, and any gate or removable section has its own rules in the same paragraph.
What is the difference between a competent person and a qualified person?
A competent person can identify existing and predictable hazards and has the employer's authority to promptly correct them, which includes stopping work. A qualified person has a degree, certificate, or extensive experience that lets them solve problems relating to the work, such as engineering an anchorage below 5,000 pounds. Subpart M assigns specific duties to each: for example, training under 1926.503 requires a competent person, and a fall protection plan under 1926.502(k) must be prepared by a qualified person.
Are the ANSI Z359 standards part of these regulations?
Not directly. OSHA regulations are federal law and free to read; ANSI Z359 is a voluntary consensus standard that manufacturers certify equipment against, and its text is copyrighted. OSHA can cite ANSI practices through the General Duty Clause, and most equipment you buy today, which includes everything we stock, is built to current Z359 requirements. Where an ANSI requirement matters to a product, we summarize it in plain language on the product page and in the manufacturer test reports we host.
