Understanding Fall Protection Harnesses

A fall protection harness constitutes the central component of personal fall arrest systems, distributing arrest forces effectively across crucial areas such as thighs, pelvis, chest, and shoulders. This distribution minimizes injury risk, crucial since falls are a significant cause of fatal work injuries, especially during construction activities.

Workplace Safety Importance

Fall-related fatalities and injuries occur disproportionately across industries. NIOSH emphasizes risk factors and prevention strategies, advocating for engineering controls and robust PPE practices for all-round protection. OSHA stipulates required systems and practices, while ANSI/ASSP's Z359 standard sets criteria for harness design, labeling, performance, and testing. These frameworks collectively provide valuable guidelines for product assessment and practical application.

OSHA Harness Use Requirements

OSHA establishes criteria for using personal fall protection systems, encompassing harnesses, connectors, lanyards, and anchors. Essential aspects include:

• Inspection: Users must inspect body supports and components before each shift, removing any damaged parts. Specific requirements can be found in 29 CFR 1910.140.
• Compatibility: Components designed to work collectively must be used to avoid potential risks like rollout or gate loading.
• Attachment Point: The dorsal D-ring should be positioned near shoulder level to minimize free fall distance and arresting force.
• Training: Users require training on selection, inspection, donning, application, limitations, and rescue.
• Rescue: Employers must ensure prompt rescue or self-rescue capability post-arrest, addressing Subpart M expectations.

Guidelines apply whether procuring a brand new harness or managing existing equipment.

Proper Harness Wearing Technique

Following manufacturer instructions and OSHA/ANSI criteria ensures correct harness wear:

1. Grasp the dorsal D-ring and shake out straps to straighten webbing.
2. Slip on shoulder straps; center the dorsal D-ring between shoulder blades.
3. Secure and snug leg straps with a flat hand clearance.
4. Fasten the chest strap positioned mid-chest.
5. Adjust torso straps to remove twists, securing excess webbing.
6. Conduct a buddy check for labels, stitching, hardware, and fit verification.
7. Connect to a compliant anchor using approved connectors, checking fall clearance and swing hazards.

Frequent inspections and evaluations by competent persons ensure alignment with OSHA mandates and ANSI guidelines.

Wearing Jackets Over Safety Harnesses

Wearing outer layers over a safety harness is permissible with some constraints, such as ensuring inspection, D-ring access, and lanyard/SRL function remain unobstructed. Many workers prefer wearing harnesses over outerwear for inspection ease, while others choose garments with D-ring pass-through slots. Compliance with OSHA’s PPE selection and usage regulations is necessary. Employers should define garment specifications and pass-through requirements within site procedures.

Practical Guidance on Harness Purchase and Use

• Select models conforming to ANSI/ASSP Z359.11 standards when practical, and assess energy absorber and connector compatibility within the system.
• Emphasize harness adjustability, D-ring positioning, and padding that promotes correct use.
• Standardize inspection tags, serials, and criteria; ensure records match OSHA inspection expectations.
• Integrate a rescue plan around installed systems, confirm reach and descent methods, and maintain a consistent training schedule.
• For colder climates, select outerwear with D-ring pass-throughs or wear harnesses atop clothing for visibility and inspection simplicity.

Wearing a Jacket Over Your Harness

When temperatures drop or sparks fly, workers often add layers to their attire. However, wear less clothing fall arrest performance remains paramount. The Occupational Safety and Health Administration (OSHA) mandates the use, inspection, and maintenance of personal fall protection (PFP) to ensure anchors stay secure and accessible. Systems require assessment for any damage or signs of wear before each shift as outlined in 29 CFR 1910.140 and 1926.502. For detailed information on PFP systems and construction safety measures, review the official OSHA standards:

• OSHA Standard 1910.140
• OSHA Standard 1926.502

Essential Rules for Adding Layers

Key procedures should be followed to maintain safety when covering a harness with outerwear:

• Accessibility of D-Rings: Ensure dorsal, sternal, and side D-rings are either left exposed or reachable through purpose-made pass-throughs. The Center for Construction Research and Training (CPWR) advises careful equipment selection while ensuring attachment points are unobstructed. For further guidance, consult their fall protection overview.

• Visibility and Adjustability: Keep chest buckles, leg straps, and torso adjusters visible and accessible to verify fit initially, then recheck after tasks requiring movement.

• Inspection Labels: Inspection labels must remain readable. OSHA's mandate for pre-shift inspections means bulky outerwear can’t impede these checks.

• Prevent Snags: Loose hems, cords, or tool leashes should not cross webbing or lanyards. The National Institute for Occupational Safety and Health (NIOSH) emphasizes the control of such hazards as part of a robust safety program. For more, see NIOSH falls topic page.

• Best Practices and Standards: For guidance on compatibility and connector geometry, refer to ANSI/ASSP Z359 series, a widely recognized industry best practice: ASSP Z359 series standards.

Prioritizing Safety in Layering

Manufacturers often recommend wearing the harness over outerwear to maintain exposed connection points, facilitating speedier pre-use inspections and buddy verifications. Nevertheless, in circumstances where a jacket overs the harness, protective garments with certified D-ring pass-throughs should align with their respective rings. Ensure these flaps do not bind connectors when loaded.

Employers should opt for slim-fitting clothing to minimize snagging and maintain appropriate adjustment limits as thicker clothing can loosen during work activities. Additionally, if flame resistance or arc-rated protection is required, select garments rated for the task and verify compatibility with harness components. Examine clearance and swing potential post-layering, as adjustments may impact arrest distance. Visit the HSE’s work at height guidance for extensive direction.

Correct Sequence for Wearing a Safety Harness

Ensuring safety begins with the proper donning of harness equipment:

1. Inspect the System: Check thoroughly for cuts, hardware deformities, corrosion, stitching issues, and readable labels—OSHA mandates a per-shift review.
2. Hold and Shake: Take the harness by the dorsal D-ring and shake to untangle.
3. Don Properly: Place shoulder straps carefully without twists, fasten leg straps to snug with a flat-hand clearance.
4. Connect the Chest Strap: Fasten at mid-chest, ensuring it doesn’t migrate to the neck or abdomen.
5. Position Dorsal D-Ring: Set it between shoulder blades.
6. Stow Excess Straps: Use keepers to eliminate snag hazards from loose strap ends.
7. Buddy Check: Verify fit before attaching an appropriate lanyard or self-retracting lifeline (SRL) to a compatible anchor above the D-ring height when feasible.

Comprehensive safety programs should integrate outerwear considerations into hazard assessments, procedures, and toolbox discussions. CPWR and NIOSH support effective planning, supervision, and training with a plethora of resources: NIOSH falls resources | CPWR fall protection resources.

Available outerwear products with integrated D-ring pass-throughs, low-bulk insulation, and snag-resistant features can enhance both safety and convenience. Validating the compatibility for harnesses, connectors, lanyards, and garments during pre-job trials can be beneficial for ensuring a safe working environment.
