Synthetic Web Sling Inspection and Safety
The Problem
Synthetic web slings are essential tools for lifting, hoisting, and moving heavy loads, but they can fail catastrophically if damaged, improperly inspected, or poorly maintained. A failed sling can result in dropped loads, serious injuries, or fatalities. The issue is straightforward: damaged slings present a preventable safety risk. Today, we’ll discuss how to properly inspect synthetic web slings and remove them from service when necessary.
Identify the Hazards
Identify the Hazards
- Dropped Loads – Risk of serious injury or property damage.
- Injuries – Crushed limbs, lacerations, or fatalities caused by falling items.
- Compromised Equipment – Damaged fittings or webbing may give a false sense of safety.
Common hazards include:
- Cuts, abrasions, or fraying
- Heat or UV damage
- Chemical exposure
- Makeshift repairs or unreadable sling tags
Safety Practices and Preventative Measures
Visual Inspection for Cuts and Abrasions
- Look for cuts, fraying, or nicks along the webbing.
- Action: Tag and remove damaged slings from service immediately.
Inspect Stitching
- Check for broken, loose, or rotten threads.
- Action: Faulty stitching compromises strength — do not use.
Examine Load-Bearing Fittings
- Inspect lifting rings and other fittings for cracks, deformation, or corrosion.
- Tip: If the fitting is damaged, the sling is unsafe.
Inspect Eye Loops
- Look for damage, twisting, or stretching in the eye loops.
- Damaged loops reduce the sling’s lifting capacity.
Avoid Knots or Makeshift Repairs
- Never tie knots or attempt temporary repairs.
- Action: Tag and remove such slings from service.
Check for Heat Damage
- Look for melting, charring, or hard spots.
- Action: Heat damage weakens the sling — replace it.
Check for UV Damage
- Inspect for fading, brittleness, or discolouration.
- UV damage deteriorates synthetic fibres.
Inspect for Chemical Exposure
- Signs include staining, discolouration, or stiffness.
- Action: Seek advice from your supervisor before reuse.
Moisture or Mildew Damage
- Signs of mildew or waterlogging can weaken the sling over time.
- Action: Remove from service if detected.
Ensure Sling Tag is Legible
- The tag must clearly state the sling’s rated capacity and safety information.
- Action: If the label is missing or unreadable, do not use the sling.
Real-Life Case or Scenario
A worker used a synthetic sling that had minor fraying and a tear. During the lift, the sling failed and dropped a heavy load. Fortunately, no one was injured, but the incident caused significant delays and equipment damage. This could have been prevented by conducting a thorough pre-use inspection.
Employee Responsibilities
- Inspect slings before every use.
- Tag and report defective slings.
- Never use slings with visible damage, missing tags, or makeshift repairs.
- Raise any concerns with your supervisor immediately.
Employer Responsibilities
Discussion & Questions
- What types of damage do you typically see on synthetic slings during inspections?
- Have you ever removed a sling from service? What triggered that decision?
- Do you feel confident identifying damage or potential hazards?
Encourage workers to share their experiences and concerns.
Commitment/Action Plan
Let’s commit to inspecting every sling before use. If there’s any doubt about its condition, don’t take a chance — tag it, remove it, and report it. A two-minute inspection can prevent a life-changing accident.
Wrap-Up
Synthetic web sling failures are entirely preventable. Regular inspections and safe handling practices protect everyone on site. Let’s all do our part to maintain a safe lifting environment. Thanks for putting safety first.
Standards Overview
In Canada, lifting equipment must be inspected regularly and removed from service if found unsafe, following applicable provincial regulations and industry standards. Employers are responsible for ensuring all lifting gear is fit for purpose and inspected by a qualified person before use.
