OSHA fall restraint system requirements sit in two places: 29 CFR 1910.140 for general industry, and 29 CFR 1926 Subpart M for construction, where OSHA has accepted properly rigged restraint in lieu of fall arrest since 1995. A compliant system is rigged so the worker cannot reach an unprotected edge, uses body support, a lanyard, connectors, and an anchorage that meet federal strength ratings, is inspected before every shift, and is backed by documented training. Miss any one of those, and you no longer have a restraint system OSHA will recognize.
Restraint Is Not Arrest
A fall restraint system keeps a worker from reaching the edge. A fall arrest system catches them after they go over. That single distinction drives every hardware choice on the site. With restraint, the connection line is short enough that the worker physically cannot get to an unprotected side or opening, so the fall distance is zero and the forces on the system stay low. OSHA’s general industry rule defines a travel restraint system as the combination of anchorage, connector, lanyard, and body support that eliminates the possibility of going over the edge of a walking-working surface.1Occupational Safety and Health Administration. 29 CFR 1910.140 – Personal Fall Protection Systems
The practical consequence: body belts are allowed in restraint (and positioning) applications but prohibited in fall arrest, and anchorage strength requirements are lower for restraint than for arrest. If there is any chance the line lets a worker reach the edge, you are running an arrest scenario and the arrest numbers apply.
When Fall Protection Kicks In
The trigger height depends on the setting.
- General industry: 4 feet above a lower level. Travel restraint is explicitly listed as an acceptable option.2Occupational Safety and Health Administration. 29 CFR 1910.28 – Duty to Have Fall Protection and Falling Object Protection
- Construction: 6 feet above a lower level.3eCFR. 29 CFR 1926.501 – Duty to Have Fall Protection
- Scaffolding: more than 10 feet above the next lower level.4eCFR. 29 CFR 1926.451 – General Requirements for Scaffolds
- Dangerous equipment: any height. Below 4 feet above dangerous equipment, a guardrail or travel restraint system is required unless the equipment is covered or guarded. At 4 feet or more, the full range of fall protection options applies.2Occupational Safety and Health Administration. 29 CFR 1910.28 – Duty to Have Fall Protection and Falling Object Protection
Anchorage and Line Strength
The strength numbers are different in general industry and construction, and that is the compliance mistake OSHA sees most often.
General Industry
Anchorages for any personal fall protection system, including travel restraint, must support at least 5,000 pounds (22.2 kN) per attached employee. The alternative is an anchorage 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. Travel restraint lines themselves must also sustain a tensile load of at least 5,000 pounds.5eCFR. 29 CFR 1910.140 – Personal Fall Protection Systems
Construction
Subpart M does not contain a standalone restraint section. In formal interpretation letters, OSHA has said it accepts restraint in lieu of arrest when the system is rigged so the worker cannot reach the fall hazard. For restraint anchorages in construction, OSHA suggests a minimum of 3,000 pounds of force, or twice the maximum expected force needed to restrain the worker, whichever is greater. Slope, walking force, and the possibility of sliding all figure into that expected force calculation.6Occupational Safety and Health Administration. Fall Restraint System Used in Lieu of Fall Arrest Systems
Do not carry these figures over to arrest. Personal fall arrest anchorages in construction must support 5,000 pounds per attached employee or be engineered with a safety factor of two under a qualified person’s supervision.7eCFR. 29 CFR 1926.502 – Fall Protection Systems Criteria and Practices
The Four Required Components
A travel restraint system has four parts, and each has to meet federal specifications. Improvising any one of them breaks the system.
- Body support. Either a full-body harness or, in restraint and positioning applications, a body belt. A harness spreads force across the thighs, pelvis, waist, chest, and shoulders; a body belt secures at the waist only. Body belts are permitted for restraint and positioning, but prohibited for fall arrest.1Occupational Safety and Health Administration. 29 CFR 1910.140 – Personal Fall Protection Systems
- Lanyard or restraint line. Connects body support to anchorage. It must be short enough to prevent the worker from reaching any unprotected edge or opening. If the length math is off, the system is no longer restraint.
- Connectors: snaphooks, carabiners, and D-rings. Each must sustain a minimum tensile load of 5,000 pounds and be proof-tested to 3,600 pounds without cracking or permanent deformation.5eCFR. 29 CFR 1910.140 – Personal Fall Protection Systems
- Anchorage connector. Secures the line to the structure, and the structural anchorage behind it has to meet the capacity numbers above.
Manufacturers publish compatibility instructions for their components. Mixing incompatible parts can cause roll-out, where a connector slips off a D-ring, or a gate opens under side-loading.
Snaphook and Carabiner Rules
All snaphooks and carabiners must be the automatic-locking type, requiring at least two separate, consecutive movements to open. Non-locking snaphooks are prohibited. Gate strength must withstand at least 3,600 pounds without the gate separating from the nose by more than one-eighth of an inch.5eCFR. 29 CFR 1910.140 – Personal Fall Protection Systems
Connectors also cannot be clipped to certain things unless they were specifically designed for that connection. No hooking a snaphook directly to webbing, rope, or wire rope. No clipping two snaphooks to each other. No attaching to any object whose shape or size could depress the gate and cause an unintentional release.5eCFR. 29 CFR 1910.140 – Personal Fall Protection Systems Connector hardware must be drop-forged, pressed, or formed steel (or equivalent material) with a corrosion-resistant finish and smooth edges.
Pre-Shift Inspection and Removal From Service
Every piece of fall protection equipment must be inspected before the first use of each work shift. The check covers mildew, wear, damage, and general deterioration. Any defective component must be pulled from service immediately.5eCFR. 29 CFR 1910.140 – Personal Fall Protection Systems
Look for fraying or cuts in webbing, corrosion or cracks on metal parts, and any stiffness or failure in a snaphook or carabiner’s locking mechanism. Every harness must carry a legible manufacturer label with the model, date of manufacture, and any limitations or warnings. A missing or unreadable label is a reason to remove the harness from service.8Occupational Safety and Health Administration. Lifeline Harness Inspection Guide
Any component subjected to impact loading must be taken out of service immediately and left out until a competent person inspects it and confirms it is undamaged and safe. Under OSHA’s definition, a competent person can identify existing and predictable fall hazards and has the authority to take corrective action.1Occupational Safety and Health Administration. 29 CFR 1910.140 – Personal Fall Protection Systems
Training and Written Certification
Equipment alone does not satisfy the standard. In construction, every employee exposed to a fall hazard must be trained by a competent person on the nature of the hazards in the work area, the correct procedures for erecting and inspecting fall protection systems, and the proper use of the specific systems on site.9Occupational Safety and Health Administration. 29 CFR 1926.503 – Training Requirements
The employer must produce a written certification record listing the employee’s name, the training date, and the signature of the trainer or employer, and keep the most recent certification on file. If the employer is relying on training done by a previous employer, the record shows the date the current employer verified that earlier training, not the original training date.9Occupational Safety and Health Administration. 29 CFR 1926.503 – Training Requirements
Retraining is required when workplace changes make prior training outdated, when new equipment is introduced, or when a worker’s actions show they have not retained the skills. That last trigger is the one employers overlook. A supervisor who sees a snaphook clipped incorrectly or a restraint line rigged too long has just created a retraining obligation.9Occupational Safety and Health Administration. 29 CFR 1926.503 – Training Requirements
Penalties
OSHA penalty amounts adjust annually for inflation. As of January 2025, the maximum for a serious or other-than-serious violation is $16,550 per instance. Willful or repeated violations run up to $165,514 per violation.10Occupational Safety and Health Administration. OSHA Penalties A single site with multiple workers on improperly rated anchors, non-locking connectors, or missing training records can generate separate citations for each deficiency. Documenting inspections, training, and anchorage engineering is the practical defense when an inspector arrives.
