1910.28(b): Fall protection in general industry (4-foot rule)

By Black Belt Safety Editorial Team Official text as of octubre 15, 2026 Data updated octubre 20, 2026 12 min read

In plain words:

In general industry, workers on a walking-working surface with an unprotected side or edge 4 feet or more above a lower level must be protected by a guardrail system, a safety net system, or a personal fall protection system such as fall arrest, travel restraint or positioning. A written fall protection plan can replace those systems only on residential roofs, and only when the employer shows they are not feasible or would create a greater hazard. Paragraph (b) also sets fall protection rules for specific places such as hoist areas, holes, dockboards, runways, dangerous equipment, wall openings, fixed ladders and stairways.

What this rule covers

29 CFR 1910.28(b) ("Protection from fall hazards") is one requirement inside 1910.28 Duty to have fall protection and falling object protection, an OSHA general industry standard (Part 1910, Subpart D). It includes 102 sub-paragraphs. The official text below is copied word for word from the Electronic Code of Federal Regulations (eCFR). The numbers, injury cases and training on this page show how OSHA enforces it on real job sites.

(1) Unprotected sides and edges. Open (b)(1) 1,938 citations

(i) Except as provided elsewhere in this section, the employer must ensure that each employee on a walking-working surface with an unprotected side or edge that is 4 feet (1.2 m) or more above a lower level is protected from falling by one or more of the following: Open (b)(1)(i) 1,933 citations

(A) Guardrail systems; Open (b)(1)(i)(a) 61 citations

(B) Safety net systems; or

(C) Personal fall protection systems, such as personal fall arrest, travel restraint, or positioning systems. Open (b)(1)(i)(c) 28 citations

(ii) When the employer can demonstrate that it is not feasible or creates a greater hazard to use guardrail, safety net, or personal fall protection systems on residential roofs, the employer must develop and implement a fall protection plan that meets the requirements of 29 CFR 1926.502(k) and training that meets the requirements of 29 CFR 1926.503(a) and (c). 3 citations

There is a presumption that it is feasible and will not create a greater hazard to use at least one of the above-listed fall protection systems specified in paragraph (b)(1)(i) of this section. Accordingly, the employer has the burden of establishing that it is not feasible or creates a greater hazard to provide the fall protection systems specified in paragraph (b)(1)(i) and that it is necessary to implement a fall protection plan that complies with § 1926.502(k) in the particular work operation, in lieu of implementing any of those systems.

(iii) When the employer can demonstrate that the use of fall protection systems is not feasible on the working side of a platform used at a loading rack, loading dock, or teeming platform, the work may be done without a fall protection system, provided: 1 citations

(A) The work operation for which fall protection is infeasible is in process;

(B) Access to the platform is limited to authorized employees; and,

(C) The authorized employees are trained in accordance with § 1910.30. 1 citations

Frequently asked questions

At what height is fall protection required in general industry?

At 4 feet or more above a lower level on an unprotected side or edge, unless another part of 1910.28 sets a different rule for that situation.

Can we use a fall protection plan instead of guardrails or harnesses?

Only on residential roofs, when the employer can show the listed systems are not feasible or create a greater hazard. The plan must meet 1926.502(k) and the training must meet 1926.503(a) and (c).

Is the construction rule the same?

No. Construction is covered by Part 1926 Subpart M, which generally uses 6 feet. 1910.28 covers general industry.
