Standard Operating Procedure: Safety Harness Inspection (South Africa)

Introduction

In accordance with the South African Occupational Health and Safety Act (Act 85 of 1993) and the Construction Regulations 2014, all fall arrest equipment must be inspected by a competent person before each use and subjected to a formal recorded inspection at least every six months. This SOP outlines the mandatory requirements for inspecting personal protective equipment (PPE) for working at heights to ensure compliance with South African National Standards (SANS 50361). Failure to maintain inspection records can lead to legal liability and, more critically, fatal workplace accidents.

Pre-Use Inspection Checklist

1. Webbing and Stitching Inspection

• Check for fraying: Look for broken fibers, cuts, or "fuzzy" webbing caused by abrasion.
• Identify heat damage: Look for fused fibers, shrivelled webbing, or discolouration indicating exposure to heat, chemicals, or open flames.
• Stitching integrity: Inspect all load-bearing stitching for pulled threads, missing stitches, or signs of tension.
• Chemical contamination: Check for stiffening, brittle areas, or discolouration which may indicate exposure to acids or solvents.

2. Metal Components (D-Rings, Buckles, Adjusters)

• Deformation: Ensure all buckles and D-rings are free from bends, cracks, or distortion.
• Corrosion: Check for signs of rust or oxidation, especially if the equipment has been stored in humid or coastal environments.
• Functionality: Verify that all buckles (friction, tongue, or quick-connect) engage smoothly and lock securely.
• Sharp Edges: Run a cloth or finger carefully along the edges to ensure there are no burrs or sharp points that could cut the webbing.

3. Labels and Tags

• Legibility: Ensure the manufacturer’s label is attached and readable. It must contain the serial number, date of manufacture, and SANS compliance markings.
• Inspection Log: Confirm that the last competent person’s inspection date is within the six-month statutory limit.
• Expiry Date: Verify that the harness is still within the manufacturer's specified service life (usually 5-10 years depending on the brand).

4. Impact Indicators

• Deployment check: Inspect the impact indicator tabs (usually located near the dorsal D-ring). If these have been deployed or torn, the harness has been involved in a fall and must be immediately removed from service.

Pro Tips & Pitfalls

• Pro Tip: Use a "Cleaning and Storage" log. Store harnesses in a cool, dry place away from direct sunlight, which degrades synthetic fibers over time.
• Pro Tip: If a harness is involved in a fall, even if it looks perfect, "Retire and Destroy" it immediately. Never attempt to repair a harness; cut the webbing to ensure it cannot be reused by mistake.
• Pitfall: Do not store equipment in vehicle toolboxes where it can be crushed by heavy tools or exposed to fuel/oil spills.
• Pitfall: Overlooking "invisible" damage. A harness that has been stored in a damp container can develop internal mildew that weakens the fibers, making it fail under load despite appearing "clean."

Frequently Asked Questions (FAQ)

1. How often must a safety harness be inspected? A formal, recorded inspection by a "Competent Person" must be conducted at least every six months, but a visual check must be performed by the user before every single shift.

2. What should I do if I find a minor cut in the webbing? Remove the harness from service immediately. Tag it as "Do Not Use" and report it to your supervisor. Harness webbing cannot be repaired; if the structural integrity is compromised, the unit must be destroyed.

3. Is it mandatory to keep a written record in South Africa? Yes. Under the OHS Act, you are required to keep an up-to-date register of all lifting and fall arrest equipment. This register must be available for inspection by a Department of Employment and Labour inspector at any time.
