How Often Should Chain Slings Be Inspected?
Pre-Use Inspection
You must inspect every sling before each use. This step helps you catch issues early and prevent accidents. According to OSHA 1910.184(d):
Each day before being used, the sling and all fastenings and attachments SHALL be inspected for damage or defects by a competent person designated by the employer.
Start by checking the identification tag for the correct load capacity and manufacturer details. Lay the sling flat and clean it for a clear view. Look for excessive wear, cracks in the weld area, or severe corrosion. Remove the sling from service if you find any of these problems. Always keep a record of your inspections.
Periodic Inspection
You need to schedule a periodic inspection based on how often you use your chain slings and the environment they operate in. For normal service, plan an annual inspection. If you use slings in harsh or severe conditions, increase the frequency to every three to twelve months. Use the table below for guidance:
| Service Condition | Inspection Frequency |
|---|---|
| Normal Service | Yearly (Annual Inspection) |
| Severe Service | Monthly to Quarterly |
| Special Service | As recommended by a Qualified Person |
A certified inspector should perform these checks. Document each periodic inspection and remove any sling that shows signs of wear, cracks, or severe corrosion.
Comprehensive Inspection
A comprehensive chain sling inspection goes beyond a basic visual inspection. You or a qualified inspector must check for elongation, inspect all attachments, and verify that identification marks remain clear. The table below outlines the differences:
| Inspection Type | Procedures Involved | Frequency |
|---|---|---|
| Comprehensive Inspection | Thorough visual check, check for elongation, inspect attachments, and ensure proper identification marks | Less frequent |
| Routine Checks | Basic visual inspection, quick checks for obvious damage | More frequent |
Follow manufacturer guidance for inspection intervals. Powerful recommends that you always use a competent person for every inspection and keep detailed records to ensure compliance and safety.
