Alloy Steel Chain Sling Inspection and Safety
The Problem
Alloy steel chain slings are critical tools used for lifting and moving heavy loads. However, if they are damaged or improperly inspected, they can fail, leading to dropped loads, injuries, or even fatalities. The problem? Many of these failures are entirely preventable. Today, we’ll address how to properly inspect chain slings, identify potential hazards, and take the necessary steps to ensure everyone stays safe.
Identify the Hazards
- Dropped Loads: Failure under stress due to cracks, stretching, or rust.
- Structural Damage: Twisted or bent links, weakened hooks, or heat damage.
- Makeshift Repairs: Use of improper bolts, repairs, or missing tags.
- Heat and Environmental Factors: Exposure to flames, rust, or overloading reduces sling strength.
Safety Practices and Preventative Measures
To prevent these hazards, always follow these inspection steps before each use:
- Visual Inspection for Damage:
- Look for cracks, nicks, gouges, or deformities in the chain assembly.
- Pay special attention to master links and coupling links.
- Rust and Corrosion:
- Check for any signs of rust or corrosion, as this can weaken the sling.
- Action: If rust is found, remove the sling from service until assessed.
- Twisted or Bent Links:
- Look for any twisting or bending in the chain links, even slight distortions.
- Action: Take the sling out of service if deformities are found.
- Heat or Flame Damage:
- Inspect for melting, discoloration, or other heat-related damage.
- Action: Remove any heat-damaged slings immediately.
- Elongation or Stretching:
- Check for signs of stretching, which could mean fatigue or overloading.
- Action: Do not use stretched slings; remove them from service.
- Hooks and Rings:
- Inspect hooks and rings for twisting, stretching, or deformation caused by overloading.
- Replace hooks and rings that show any signs of damage.
- Avoid Makeshift Repairs:
- Check for non-standard repairs like bolts or connectors that are not manufacturer-approved.
- Action: Remove slings with makeshift repairs immediately.
- Manufacturer’s Tag:
- Ensure the sling has a legible tag with its serial number, length, and rated capacities.
- Action: If the tag is missing or unreadable, do not use the sling.
- Follow Manufacturer’s Guidelines:
- Always follow the specific inspection and maintenance steps provided by the manufacturer.
- Always follow the specific inspection and maintenance steps provided by the manufacturer.
- Remove Damaged Slings from Service:
- If any damage is found, tag and lock out the sling to prevent use.
- Report it to your supervisor and follow company procedures for replacement or repair.
Real-Life Case or Scenario
A worker on a job site ignored a twisted link in a chain sling during inspection. Under load, the sling failed, causing a heavy beam to drop. Thankfully, no one was injured, but the incident delayed the project and could have had far worse consequences. This failure could have been avoided by removing the sling from service.
Employee Responsibilities

- Only manufacturer-approved repairs are conducted.
- Defective slings are tagged out, removed, and replaced promptly.
Discussion & Questions
- "What are some of the most common types of damage you’ve seen during chain sling inspections?"
- "How do you typically handle a damaged chain sling on-site?"
Allow time for employees to respond and share their experiences.
Commitment/Action Plan
Starting today, let’s commit to inspecting every alloy steel chain sling before use. If you notice any damage or concerns, tag it out and report it immediately. Your inspection could prevent a serious accident.
Wrap-Up
Chain sling safety is a team effort. By conducting regular inspections and taking damaged equipment out of service, we can keep ourselves, our coworkers, and the worksite safe. Thank you for paying attention and prioritizing safety.
Standards Overview
- OSHA requires that alloy steel chain slings be inspected before each use and that damaged or defective slings be removed from service (OSHA 1910.184).
- Inspections must follow manufacturer guidelines, and any signs of damage, wear, or elongation must be acted on immediately to prevent sling failure.
