Fall Protection for General Industry: Passing 1910.28 and Failing 1910.29

General industry fall protection starts at 4 feet under 1910.28. The citation usually lands on 1910.29: 42-inch rails, 200 pounds, no deflection past 39 inches.

by iSi Environmental

A plant puts guardrail along every open mezzanine edge, around the service pit and across the roof hatch landing. Every exposed edge has steel on it. The inspector still writes a citation, because the top rail measures 38 inches and nobody can show it holds 200 pounds applied within 2 inches of the top edge.

General industry fall protection is two rules stacked on each other, and the facilities that fail usually fail the second one. 29 CFR 1910.28 sets the duty: when you owe protection and which categories of system count. 29 CFR 1910.29 sets the criteria: what each category has to measure and withstand before it qualifies as the thing 1910.28 named. The two are cited separately, so a facility can satisfy the duty with hardware at every edge and still own a 1910.29 citation on the hardware.

Both sections sit in 29 CFR part 1910 subpart D, Walking-Working Surfaces, which OSHA rewrote in a final rule published at 81 FR 82981 on November 18, 2016. It replaced a 1971-vintage subpart with three operative sections: 1910.28 for the duty, 1910.29 for the criteria, and 1910.30 for training. The eCFR copy of 1910.28 reads as current through 7/16/2026.

There is a second reason to read subpart D closely in 2026. On February 26, 2026, OSHA told its Regional Administrators in writing that it will not issue citations under two of subpart D’s own published stair rail and handrail provisions. That memorandum is still operative, and it sits alongside a proposed rule that would delete a fall protection deadline rather than add one. Planning this year has to account for a standard being relaxed in two places while the 4-foot duty stays exactly where it has been since 2017.

One frame correction first. OSHA’s FY2026 preliminary Top 10 most frequently cited standards is led by 29 CFR 1926.501, construction fall protection, and four of the ten entries are construction fall related. 1910.28 is not on the list. General industry fall exposure is real and it kills people, and it is not where OSHA’s programmed inspection machinery is pointed. A manufacturer who reads the top ten and concludes fall protection is OSHA’s obsession is reading a construction statistic.

At what height does OSHA require fall protection in general industry?

Four feet. 29 CFR 1910.28(b)(1) requires protection wherever a walking-working surface has an unprotected side or edge 4 feet (1.2 m) or more above a lower level, using a guardrail system, a safety net system, or a personal fall protection system. The familiar 6-foot trigger belongs to construction under 1926.501 and does not apply inside a general industry plant.

The 4-foot number is only the opening line of 1910.28(b), which runs fifteen scenarios, several with their own trigger and their own list of permitted systems. Hoist areas at (b)(2) trigger at 4 feet. Holes at (b)(3) allow covers, guardrails, travel restraint or fall arrest at 4 feet or more, and only covers or guardrails below 4 feet. Dockboards, runways, repair and service pits, fixed ladders, outdoor advertising, stairways, scaffolds and rope descent systems, low-slope roofs and slaughtering facility platforms each carry their own paragraph. Dangerous equipment at (b)(6) breaks the 4-foot habit: below 4 feet you still owe a guardrail or travel restraint unless the equipment is covered or guarded. And (b)(15) catches every walking-working surface not otherwise addressed, at 4 feet.

Does OSHA’s 4-foot rule apply to every surface in my plant?

No. 1910.28(a)(2) lists seven exceptions: portable ladders; an employer inspecting, investigating or assessing conditions before work starts or after it finishes; entertainment stage and rail station platform perimeters; powered platforms under 1910.66(j); aerial lifts under 1910.67(c)(2)(v); telecommunications work under 1910.268(n)(7) and (8); and electric power generation, transmission and distribution work under 1910.269(g)(2)(i). Everything else is in scope.

Exception (ii) is the one that gets stretched. It covers the walk out to look at the problem, before work begins or after it is finished. It stops applying the moment fall protection meeting 1910.29 is installed and available for those assessments, and it never covers the repair itself. A maintenance lead who walks an unprotected roof to find the leak is inside the exception. The same person kneeling on the curb with a tool in hand is outside it.

Nothing in that list sets a size limit. There is no employee-count threshold, no NAICS carve-out and no small-business exemption in 1910.28, 1910.29 or 1910.30. Two questions settle applicability for most buildings. Does anyone work on a surface with an unprotected side or edge 4 feet or more above a lower level, including mezzanines, platforms, pits and docks? Does anyone go on the roof for any reason, including HVAC service? One yes puts the facility inside subpart D.

What fall protection does OSHA require on a low-slope roof?

It depends on distance from the edge. Under 1910.28(b)(13), work less than 6 feet from the edge always requires fall protection. Work from 6 feet to less than 15 feet requires fall protection, with a designated area allowed only for work that is both infrequent and temporary. At 15 feet or more, a designated area suffices.

The 15-foot tier carries one option facilities miss. Work that is both infrequent and temporary at 15 feet or more is exempt from fall protection entirely, but only if the employer implements and enforces a work rule keeping employees 15 feet back from the edge without protection. The verb is enforces. A rule that lives in a binder and not in anyone’s behavior does not buy the exemption.

The practical failure is treating a roof as one zone. A unit at the parapet and a unit in the middle of the field sit in two different tiers of the same paragraph, and the crew servicing both on the same morning needs two different answers.

What exactly does a guardrail have to measure and withstand?

42 inches plus or minus 3 inches. Under 1910.29(b), the top rail sits at that height above the walking surface and must withstand at least 200 pounds (890 N) applied downward or outward within 2 inches of the top edge at any point along the rail. Under that load it may not deflect below 39 inches. Midrails take 150 pounds.

The rest of paragraph (b) is where in-house fabrication gets caught. Midrails go midway between the top edge and the walking surface wherever there is no wall or parapet at least 21 inches high. Openings and baluster spacing may not exceed 19 inches. Top rails and midrails must be at least 0.25 inches in diameter or thickness. A rail above 45 inches is allowed if every other criterion in (b) is still met at that height.

Toeboards are a separate obligation under 1910.29(k) where falling object protection applies: 3.5 inches minimum vertical height, 2.5 inches around vehicle repair, service or assembly pits, and at least 50 pounds applied downward or outward.

When can a painted line replace a guardrail?

Only on a low-slope roof, as a designated area meeting 1910.29(d). The warning line needs a 200-pound breaking strength, must sit between 34 and 39 inches above the surface at its lowest point including sag, must be visible from 25 feet, and must be at least 6 feet from the edge for temporary and infrequent work or 15 feet otherwise.

Paint on the deck satisfies none of that. A designated area is a physical warning line with a measurable height, breaking strength and setback, erected on all sides of the work area. Mobile mechanical equipment changes the geometry again: the line runs at least 6 feet from the edge parallel to the direction of travel and at least 10 feet perpendicular to it.

This trade is available nowhere else in subpart D. A mezzanine edge, a dock edge or an open-sided platform takes a guardrail, a net or a personal fall protection system.

Do I need fall protection around a service pit in my maintenance bay?

Not if you meet every condition in 1910.28(b)(8). The pit must be less than 10 feet deep, access within 6 feet must be limited to trained authorized employees, floor markings or warning lines and stanchions must sit 6 feet from the edge, and “Caution Open Pit” signs must be posted. Miss one condition and the 4-foot duty applies.

This is a four-part test with no partial credit. The usual gap is the 6-foot access limit, because a pit in a working bay rarely has a controlled boundary once a vehicle, a parts cart and a tool chest are staged around it. The second is the sign, which is cheap and which an inspector confirms from the doorway. A pit 10 feet deep or more has no exemption to claim at all, and falls back to the general duty at (b)(1).

What fall protection applies at a loading dock or dockboard?

1910.28(b)(4) triggers at 4 feet and requires a guardrail or handrails at the dockboard. The exemption is narrow. It applies only where dock operations involve only motorized equipment, the fall exposure is 10 feet or less, and employees have been trained. A dock where people walk the edge is not exempt by virtue of being a dock.

Read “only motorized equipment” literally, because that is how it will be read back to you. A dock where a forklift runs the board and a receiving clerk also steps onto it with a clipboard has foot traffic, and the exemption does not reach it. Most docks in a working plant have both. The training condition is a condition too, documented under 1910.30 like any other fall protection training, so an exemption resting on trained employees fails when the records do not exist.

When must a stairway have a handrail on each open side?

Under 1910.28(b)(11), a flight with at least 3 treads and 4 risers needs stair rails and handrails, and a landing with an unprotected side 4 feet or more above a lower level needs a guardrail or stair rail. For stairs under 44 inches wide with two open sides, OSHA’s published Table D-2 and its current enforcement position do not match.

That mismatch traces to a 2021 proposed rule at 86 FR 27332 that has not reached a final rule, and to the interim enforcement memorandum covered next. Until the proposal resolves, the printed table and the citation policy are two different documents, and a facility reading only one of them will plan the wrong retrofit. OSHA addressed stair angle and tread depth under subpart D in a June 17, 2025 letter of interpretation, the source to check before modifying an existing flight.

What is OSHA’s interim enforcement position on stair rails and handrails?

On February 26, 2026, OSHA’s Directorate of Enforcement Programs issued a memorandum to Regional Administrators and State Plan Designees stating that citations for violations of 1910.28(b)(11)(ii) and 1910.29(f)(1) will not be issued for systems installed before any final rule takes effect, provided they comply with the requirements proposed in the 2021 NPRM. It replaces a September 23, 2019 memorandum.

The compliance options it names are specific. A stair rail system height of no less than 30 inches is acceptable. A top rail between 30 and 38 inches may also serve as the handrail if it meets the other handrail requirements of paragraph (f). Where the top rail exceeds 38 inches, a separate handrail is required at no less than 30 and no more than 38 inches. For pre-existing stairs under 44 inches wide with two open sides, a stair rail system is required on each open side and a separate handrail is not.

Two limits matter for planning. The memorandum covers systems installed before the effective date of a final rule, so it is not a license to build new stairs to the proposal. And it states that it becomes invalid on the effective date of any final rule resulting from the 2021 NPRM. No final rule on that proposal was located in this review, and no notice reopening the record was found, so the 2021 proposal remains pending and the February 2026 memorandum is the operative enforcement position.

When must fall protection retraining be provided?

1910.30(c) requires retraining whenever the employer has reason to believe an employee lacks the understanding and skill the standard requires. Three triggers are named: workplace changes that render earlier training obsolete or inadequate, changes in the types of fall protection systems or equipment in use, and inadequacies in an employee’s knowledge or use. The standard sets no annual interval.

The absence of a fixed interval cuts both ways. A facility that trains every January and nothing else has not satisfied (c) if it swapped harness or lanyard types in March. Reconfigure a mezzanine, add a roof anchor system or move from a guardrail to travel restraint and retraining is owed to everyone exposed to that change.

The third trigger is the one supervisors act on in the moment. Someone observed tying off to a conduit run or clipping a lanyard to a guardrail has supplied the evidence of inadequate knowledge or use, and (c) obligates retraining. Initial training happens before exposure, delivered by a qualified person.

Does OSHA’s Fall Prevention National Emphasis Program cover manufacturing plants?

Only in part. CPL 03-00-025, effective May 1, 2023, states that the instruction applies OSHA-wide and that all construction inspections related to falls will be conducted under it. For non-construction work it targets ten named activities, including rooftop mechanical work and maintenance, window cleaning and gutter cleaning. A mezzanine edge inside a plant is not on that list.

The ten are rooftop mechanical work and maintenance; utility line work and maintenance; arborist and tree trimming; holiday light installation; road sign maintenance and billboards; power washing buildings where no painting is involved; gutter cleaning; chimney cleaning; window cleaning; and communication towers. The directive carries no NAICS codes and no establishment targeting list for general industry, though it allows inspection of other non-construction work where a worker is observed at height, with area office approval.

Rooftop mechanical work and maintenance is on that list, and it is what a manufacturing plant does every time an HVAC unit, exhaust fan or make-up air unit needs service. A plant that files the fall NEP under “construction program” is right about its mezzanines and wrong about its own roof. The directive record states no expiration date.

What is the penalty for a general industry fall protection violation in 2026?

$16,550 per serious or other-than-serious violation and $165,514 per willful or repeated violation, with failure to abate at $16,550 per day beyond the abatement date, under OSHA’s May 21, 2026 penalty memorandum. Failure to abate is generally limited to 30 days. These are 2025 amounts carried into 2026.

The reason is unusual. DOL cancelled the 2026 inflation adjustment entirely at 91 FR 31358, published May 27, 2026, because BLS did not publish the October 2025 CPI-U during the appropriations lapse. The 2025 ceilings are the ceilings that apply now, and the schedule behind them sits at 29 CFR 1903.15.

The figures that get quoted least are the floors, and on a fall case they are the ones that bite. The same memorandum sets a minimum willful penalty of $11,823, a minimum repeat penalty of $4,256 and a minimum serious penalty of $1,085. The $11,823 is a floor, not a ceiling: a willful fall protection violation starts there and runs to $165,514. Current amounts also appear on OSHA’s penalties page.

Do Kansas, Oklahoma, Missouri, Nebraska, Texas or Colorado have different fall protection rules?

No. None of the six operates an OSHA-approved State Plan of any type. OSHA’s state plan page states individually for each of them that the state is not an OSHA-approved State Plan. Federal 1910.28, 1910.29, 1910.30 and the 1903.15 penalty schedule apply directly across all six, with no state overlay and no state-specific amendment.

Nationwide there are 29 State Plans, 22 covering private sector plus state and local government workers and 7 covering public employees only. A multi-site operator with plants inside and outside those jurisdictions has a variation problem to manage. An operator working only in the six states above has one rulebook, one penalty schedule and one enforcement policy, including the February 26, 2026 memorandum, which arrives through federal Regional Administrators rather than a state adoption process.

Is OSHA making general industry fall protection stricter?

The only live subpart D rulemaking runs the other direction. RIN 1218-AD73, proposed at 91 FR 17165 on April 6, 2026, carries the Unified Agenda designation “EO 14192 Designation: Deregulatory” and proposes to remove the November 18, 2036 fixed ladder deadline at 1910.28(b)(9)(i)(D). An industry petition received July 28, 2025 prompted it.

The agenda entry lists the proposal at Proposed Rule Stage, Priority “Economically Significant,” Major “Yes.” The comment period closed June 5, 2026. The notice also requests comment on repealing or revising the requirement and on allowing cages and wells.

Read the status carefully, because the marketing around this topic does not. 1910.28(b)(9)(i)(D) is still printed in the CFR, the eCFR copy current as of 7/16/2026 still contains it, and no final rule removing it was located in this review. The 2036 deadline is proposed for removal and it is still the law. Keep the fixed ladder retrofit in the capital plan and track the docket.

Two other signals point the same way. 1910.28 is absent from OSHA’s FY2026 preliminary top ten. And the February 2026 memorandum says plainly that complying with a proposal, rather than with the printed rule, is good enough for pre-final-rule installations. None of that reduces the duty at 1910.28(b)(1), and none of it reduces what a fall from a mezzanine does to a person. It does mean a compliance case built on “OSHA is tightening fall protection” is a case built on construction data.

Where this lands in a plant

Three measurements settle most of it. Pull a tape to the top rail on every mezzanine, platform and open-sided landing and write down what it reads. Walk the roof, mark the distance from each serviceable unit to the nearest edge, and sort it into the 6-foot and 15-foot tiers at 1910.28(b)(13). Then find the stair flights under 44 inches wide with two open sides and check them against the February 2026 memorandum.

The mezzanine rail is usually the surprise. Guardrail welded up in the maintenance shop looks correct, sits at whatever height the fabricator liked, and has never had a load applied to it or a height written down. The 200-pound capacity at 1910.29(b)(3) is part of the standard, which makes it part of the record you are expected to have.

Frequently Asked Questions

At what height does OSHA require fall protection in general industry?

Four feet. Under 29 CFR 1910.28(b)(1), employees 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.

What are OSHA’s guardrail requirements?

1910.29(b) sets the criteria: a top rail 42 inches high, plus or minus 3 inches, that withstands 200 pounds of force within 2 inches of the top edge without deflecting below 39 inches, midrails that withstand 150 pounds, and openings no more than 19 inches across.

When is fall protection required on low-slope roofs?

It depends on distance from the edge under 1910.28(b)(13). Work within 6 feet of the edge requires conventional fall protection. From 6 feet to less than 15 feet, a designated area is allowed for work that is infrequent and temporary. At 15 feet or more, infrequent and temporary work may proceed without fall protection only under an enforced work rule keeping employees at least 15 feet from the edge.

When do stairways need stair rails and handrails?

Under 1910.28(b)(11), flights with three or more treads and four or more risers require stair rail systems and handrails.
