OSHA fall protection height requirements by industry (1926.501, 1910.28)

In construction, OSHA requires fall protection when an employee works 6 feet (1.8 m) or more above a lower level. 29 CFR 1926.501(b)(1) sets that trigger for unprotected sides and edges, and 1926.501(b)(13) sets the same trigger for residential construction. Scaffolds (more than 10 feet, 1926.451(g)(1)) and steel erection (more than 15 feet, 1926.760(a)(1)) follow their own subparts.

It depends on the standard that governs the work. General industry under 29 CFR 1910.28(b)(1)(i) triggers at 4 feet or more, and construction under 29 CFR 1926.501 triggers at 6 feet or more. The same job site can carry both, so identify whether the activity is construction or general industry before applying a threshold.

Shipyard employment sets more than 5 feet above a solid surface for the edges of decks and platforms (29 CFR 1915.73(d)). Section 1915.77(c) separately calls for scaffolds, a sloping ladder, or safety belts and lifelines for work aloft or elsewhere at elevations more than 5 feet above a solid surface. Marine terminals require guardrails where employees face a fall of more than 4 feet or into the water (1917.112(b)(1)). In longshoring, a fall hazard is work within 3 feet of the unprotected edge of a surface 8 feet or more above the adjoining surface and 12 inches or more horizontally from the adjacent surface, or work on top of containers whenever weather conditions may impair vision or sound footing (1918.2). Section 1918.85(l) requires fall protection along an unguarded edge where a fall hazard exists. Where a container gantry crane is handling containers, 1918.85(j)(1) requires that no employee be on top of a container, and an employee may be there only to perform a necessary function that cannot be eliminated by the use of positive container securing devices. Sections 1918.85(j)(1) and (j)(2) also require a fall protection system for each employee on top of a container while containers are handled by container gantry cranes or other hoisting devices, and (j)(3) covers any other employee exposed to a fall hazard.

For an unprotected side or edge in construction, yes. 29 CFR 1926.501(b)(1) says 6 feet (1.8 m) or more, so an edge exactly 6 feet above a lower level is covered. Holes and skylights are worded differently. Paragraph 1926.501(b)(4)(i) says more than 6 feet, so a hole exactly 6 feet above a lower level is outside that paragraph, although (b)(4)(ii) still calls for covers against tripping in or stepping into it. General industry works the same way as (b)(1) at 4 feet or more under 1910.28(b)(1)(i). Scaffolds (1926.451(g)(1)), steel erection (1926.760(a)(1)) and shipyard deck and platform edges (1915.73(d)) say more than, so exactly 10, 15 or 5 feet does not trigger those paragraphs.

Sometimes. In construction, an employee less than 6 feet above dangerous equipment must be protected by guardrail systems or equipment guards (1926.501(b)(8)(i)), and holes and skylights must be covered against tripping or stepping into them at any height (1926.501(b)(4)(ii)). General industry has a matching dangerous equipment rule below 4 feet (1910.28(b)(6)(i)), unless the equipment is covered or guarded to eliminate the hazard.

It depends on the standard that applies. For unprotected sides and edges, 29 CFR 1926.501(b)(1) and (b)(13) list guardrail systems, safety net systems, and personal fall arrest systems. General industry, 1910.28(b)(1)(i), lists guardrail systems, safety net systems, and personal fall protection systems such as personal fall arrest, travel restraint, or positioning systems. Steel erection, 1926.760(a)(1), adds positioning device systems and fall restraint systems. Scaffolds, 1926.451(g)(1), set the system by scaffold type, mostly personal fall arrest or guardrail systems. The design and performance criteria are set out in 29 CFR 1926.502.

29 CFR 1926.451(g)(1) says "Each employee on a scaffold more than 10 feet (3.1 m) above a lower level shall be protected from falling to that lower level." The 10-foot scaffold trigger is an exception to the general 6-foot construction rule. Employees erecting or dismantling supported scaffolds follow 1926.451(g)(2) instead, which sets no height. The employer has a competent person determine the feasibility and safety of providing fall protection, and must provide it where its installation and use is feasible and does not create a greater hazard.

29 CFR 1926.760(a)(1) requires fall protection for steel-erection employees on a walking/working surface with an unprotected side or edge "more than 15 feet (4.6 m) above a lower level." Steel erection also recognizes positioning-device and fall-restraint systems alongside guardrails, nets, and personal fall arrest. Connectors and employees in a controlled decking zone are protected under 1926.760(b) and (c) instead.

In general industry, 29 CFR 1910.28(b)(9) applies to fixed ladders that "extend more than 24 feet (7.3 m) above a lower level." A ladder installed on and after November 19, 2018 needs a personal fall arrest system or a ladder safety system. A ladder installed before that date may have a cage or well instead, but on and after November 18, 2036 all fixed ladders need a personal fall arrest system or a ladder safety system. A cage or well may stay in combination with one of those systems if it does not interfere with the system. Fall protection on construction ladders is set by Subpart X instead.

Under 29 CFR 1926.760(b)(1), a connector must be protected as 1926.760(a)(1) describes from fall hazards of "more than two stories or 30 feet (9.1 m) above a lower level, whichever is less." At heights over 15 and up to 30 feet, 1926.760(b)(3) calls for a personal fall arrest system, positioning device system or fall restraint system, and the connector must wear the equipment needed to be tied off, unless other means of protection under 1926.760(a)(1) are provided. Connectors must also have completed connector training under 1926.761. A controlled decking zone may be set up in the same band, and the employees at its leading edge must be protected from fall hazards of more than two stories or 30 feet, whichever is less, under 1926.760(c)(1). The zone must meet every condition in 1926.760(c)(2) through (c)(7), which cover limited access, marked boundaries no more than 90 feet wide and 90 feet deep, CDZ training, no more than 3,000 square feet of unsecured decking, the order of deck attachments, and no final deck attachments.

They can in states that run their own OSHA-approved plans. Those standards must be "at least as effective as the Federal program," and 29 CFR 1902.4(a)(2) lets a state establish "alternative standards, procedures, criteria, and rules" to meet that test. A trigger height in a state plan may therefore differ from the federal heights on this page. Plans in Connecticut, Illinois, Maine, Massachusetts, New Jersey, New York and the Virgin Islands cover only State and local government employers and employees (29 CFR 1952.23 through 1952.29), so private employers there follow the federal heights. Check the rule in your state before you apply a height from this guide.

OSHA cited 29 CFR 1926.501 98,889 times in 94,350 inspections from January 2016 through September 10, 2026. That makes it the most-cited section of the OSHA standards in that period. Its most-cited paragraph is 1926.501(b)(13), residential construction, with 58,627 of those citations. Counting every year on file instead, 1926.501(b)(13) has 112,067 citations in construction and roughly $387 million in assessed penalties through September 2026.
