What is a Lanyard in Fall Protection?
Purpose and Role
A lanyard functions as a crucial link within a fall protection system, connecting a worker’s full-body harness to an anchorage or a lifeline. It helps manage movement and can arrest a fall if necessary. In restraint mode, it restricts mobility, preventing workers from approaching edges. When arresting falls, it works collaboratively with harnesses, anchors, and connectors, adhering to Occupational Safety and Health Administration (OSHA) guidelines to keep arresting forces within safe limits. For further reading, see OSHA's guidelines and equipment rules at their website (osha.gov/fall-protection).
Core Components
- Webbing or Rope Leg(s): Available in fixed or adjustable formats.
- Connectors: Auto-locking hooks or carabiners that comply with strength standards.
- Energy Absorber Pack: Manages deceleration, vital in shock absorbing lanyards.
- Labels: Display ratings, standards, and inspection details.
- Twin-Leg Configuration: Provides 100% tie-off for uninterrupted connection.
Lanyard vs. Harness
A harness supports and distributes arrest forces across the body, while lanyards serve as connections to anchors. Without a lanyard, a harness alone cannot limit falls. OSHA views both as integral system parts rather than individual protective measures. Proper usage is crucial for optimal safety.
OSHA and ANSI Requirements
Critical OSHA standards dictate performance limits in Personal Fall Arrest Systems (PFAS):
- Maximum Arresting Force: 1,800 pounds-force on a worker using a full-body harness.
- Maximum Deceleration Distance: 3.5 feet with energy absorption.
- Free Fall Distance: Limited to six feet or less to prevent lower-level contact.
- Anchor Strength: Each must support 5,000 pounds-force per person or be designed with a 2:1 safety factor by a qualified individual.
- Connectors: Self-closing and self-locking, with a minimum 5,000 pounds-force capacity.
Enhanced design, testing, and labeling criteria are provided by ANSI/ASSP Z359 standards widely adopted within the industry.
Training and Inspection
Proper training is essential, focusing on anchorage selection, clearance, swing hazards, and hardware compatibility. Conduct inspections before each use and remove any device involved in a fall. Guidance from the National Institute for Occupational Safety and Health (NIOSH) is available for practical solutions for employers and users.
When to Use a Lanyard
Employ fall protection lanyards when risk conditions exceed OSHA’s trigger heights and alternative engineering or platform solutions do not eliminate the hazard. Lanyards restrain travel to prevent edge approaches. Ensure compatibility with sharp edges, or choose models explicitly rated for those conditions. Avoid tying back unless designed for it.
Selection Tips for Buyers
- Identify the application need: restraint, positioning, or arrest.
- Choose lengths that respect clearance needs and minimize free fall.
- Opt for twin-leg versions ensuring 100% tie-off.
- Verify compliance to OSHA and ANSI/ASSP Z359.13 standards for energy absorbers.
- Use auto-locking hooks with correct gate throat dimensions for specific site anchors.
- Consider additional features like edge-rating, arc-flash resistance, or chemical resistance based on task demands.
Plain-Language Answers
What is the Difference Between a Lanyard and a Harness?
Lanyards connect users to anchors, while harnesses secure the body, distributing arrest forces. Both elements are necessary for safe fall arrest.
What are the OSHA Requirements for Lanyards?
OSHA mandates include limits on force (under 1,800 pounds-force), deceleration (under 3.5 feet), and free fall (six feet or less) alongside connector strength and anchor capacity as detailed in OSHA documentation.
What is a Lanyard Used For?
A lanyard serves purposes like fall arrest, work positioning, or travel restraint within a comprehensive system that includes harnesses and anchorages. Energy-absorbing lanyards diminish forces on the user during a fall.
When Should You Use a Safety Lanyard?
Utilize safety lanyards when fall hazards exist, and engineering controls or collective protection do not entirely mitigate risk. Configurations must ensure verified clearance and component compatibility for safe use.

Types of Lanyards
Selecting the appropriate connector enhances both safety and operational efficiency, particularly in settings prone to falls. Fall protection lanyards fall into several groups tailored for specific roles, settings, and environments. Two main categories dominate the selection process: shock-absorbing varieties intended for fall arrest and fixed-length alternatives used for restraint or work positioning as outlined by OSHA standards 29 CFR 1910.140 and 29 CFR 1926.502. For additional guidance, the ANSI/ASSP Z359 series outlines performance standards, ensuring buyers opt for compliant and durable equipment. Furthermore, NIOSH and HSE offer practical advice alongside regulatory information.
Shock-absorbing Lanyards
Shock-absorbing lanyards play a crucial role in fall arrest due to their integrated deceleration features, designed to reduce the forces transferred to a user's harness and anchor. According to U.S. regulations, these systems must limit the maximum arrest force to 1,800 pounds-force (8 kN), and deceleration distances are controlled to manage extension during the stop. ANSI/ASSP Z359.13 provides classifications based on allowable free-fall parameters, assisting buyers in aligning device ratings with anchor height and user weight. For scenarios where anchors are positioned at or below the dorsal D-ring, models designed for up to 12-foot falls offer an added safety margin. This category finds frequent use in sectors such as construction, tower maintenance, and environments where inadvertent slips might occur. In cases requiring continuous connection during transitions, twin-leg designs are ideal. For more insights into fall arrest principles, visitors can refer to the Wikipedia entry on fall arrest.
Restraint, Positioning, Twin-leg, and Specialty Lanyards
Restraint lanyards, either fixed or adjustable, prevent workers from reaching hazardous zones without the ability to arrest a fall. Positioning lanyards offer support when workers stabilize themselves on poles or structures, necessitating a separate fall arrest system. Twin-leg Y configurations ensure 100% tie-off, keeping one leg attached during transitions. Different materials cater to various needs: webbing suits light tasks, rope offers adjustability, while wire or aramid blends withstand high heat or sharp-edge contact. For energized settings, dielectric or arc-flash-rated options prove beneficial. Though not lanyards, Self-Retracting Lifelines (SRLs) function as connectors with automatic payout and rapid locking. Correct selection considers several factors: anchor location, compatible connectors, clearance, and user mass—according to OSHA 1910.140 and HSE guidelines. Matching fall protection lanyards to structural geometry, required mobility, environmental effects, and scheduled inspections ensures compliance with regulatory criteria and performance benchmarks detailed by ANSI/ASSP Z359.13.

Essential Overview of Safety Standards for Lanyards
When selecting lanyards for personal protection, adherence to the Occupational Safety and Health Administration's (OSHA) rules is essential. General industry guidelines are delineated in 29 CFR 1910.140, while construction standards are found in 29 CFR 1926.502. These resources provide the foundational texts needed for compliance and implementation.
Optimizing rigging configurations is critical for minimizing fall risks. OSHA stipulates a limit of six feet for free-falls, with a maximum arresting force not exceeding 1,800 pounds when using a full-body harness. Deceleration should remain under 3.5 feet, and contact with lower levels must be avoided. As per requirements, anchorages should withstand a minimum of 5,000 pounds per worker or be engineered to include a safety factor of at least two. Detailed specifications are found in sections 1910.140(d) and 1926.502(d).
Reliable connectors start with stringent hardware and material specifications. D-rings, snaphooks, and carabiners should have a tensile strength of at least 5,000 pounds, tested to 3,600 pounds without permanent deformation lines. Additionally, these components must resist corrosion and possess compatible shapes to prevent rollout. The utilization of body belts for fall arrest is strictly prohibited. Details can be reviewed in sections 1910.140(c) and 1926.502(d).
Regular inspections and timely removal of any damaged equipment bolster safety procedures. Employers need ensuring consistent pre-use examinations and should replace any impaired items promptly. Training remains fundamental, equipping workers with essential skills in hazard recognition, appropriate equipment selection, and basic rescue. Training mandates for the general industry are outlined in 1910.30, with construction training parameters in 1926.503, though state-specific OSHA plans may dictate additional criteria.
Additionally, ANSI/ASSP guidelines support federal regulations by offering detailed design and testing standards for energy-absorbing lanyards and self-retracting lifelines (SRLs). Not every provision is mandatory; however, many procurement teams specify ANSI adherence to meet OSHA’s mandatory standards. Guidance is available in the Z359 series, emphasizing design criteria and labeling, including Z359.13.
