The Web Sling and Tie Down Association defines the initial level of inspection as, “Before any new or repaired sling is placed in service, it shall be inspected by a qualified person to ensure that the correct sling is being used, as well as to determine that the sling meets the applicable requirements”.
The American Society of Mechanical Engineers also states in the initial inspection that, “prior to use, all new, altered, modified or repaired slings shall be inspected by a designated person to verify compliance to all applicable standards”.
The initial level of inspection is done upon receipt to ensure that no damage has occurred during transit. The products must also be verified to be correct, as ordered and they comply with the manufacturer’s specifications. Without printed product specifications this comparison cannot be accomplished. If written records for individual slings are to be maintained, the documentation should be initiated at this level of inspection. Recordkeeping at the initial level of inspection is not required.
The Web Sling and Tie Down Association defines the frequent level of inspection as one that is done by the user or other designated person daily or before each shift in NORMAL service conditions. When SEVERE service conditions exist, the sling must be inspected before each use. See page 476, Sling Service for definitions of Normal, Severe and Special Service. The entire sling shall be thoroughly examined and removed from service if damage is detected. OSHA and ASME stipulate that, “before each day or shift, the sling and all fastenings and attachments shall be inspected for damage and defects by a competent person designated by the employer”. If you are unsure if the daily or pre-shift inspection has been done, take the time to inspect the sling before you use it. WSTDA, OSHA and ASME provide minimum guidelines. Never assume that slings have been inspected by others.
A qualified person must also determine that the sling is proper for the intended use, hitch, load and environment. Any condition that may result in a hazard shall cause the sling to be removed from service. Written inspection records are not required for frequent inspections.
All slings must be inspected “periodically” by designated personnel at regular intervals. In order to validate the Frequent Level of Inspection, the Periodic Inspection should be done by someone other than the individual(s) who performs the Frequent Inspection. The interval is based upon: the frequency of use, severity of the service conditions, the nature of the work being performed and experience gained during the inspection of slings used in similar circumstances. Recommendations to prevent damage must be evaluated to improve the service life of the replacement slings. Periodic Inspection intervals shall not exceed one year intervals.
ASME stipulates the following time interval guidelines for Periodic Inspections:
- Normal Service - Yearly
- Severe Service - Monthly to Quarterly
- Special Service - As recommended by a Qualified Person
Written records of the most recent periodic inspection shall be maintained. Reference to a unique, sling identification number is not required. If your employer or industry requires recording the condition of individual slings, continue the practice. The important point to realize is the ASME recordkeeping requirement mandates that the event be documented not the condition of individual slings.
Irrespective of the recordkeeping requirements that govern your actions, it is important that slings inspected “periodically” be identified or tracked to validate that the Periodic Inspection occurred. Lift-It® Slings can be equipped with an Inspection Loop™, Inspection Tag or RFID chipped for easy, visual verification of Periodic Inspections (See pages 54 and 55).
Designated Person: Selected or assigned by the employer or employer’s representative as being competent to perform specific duties.
Qualified Person: A person, who by possession of a recognized degree or certificate of professional standing in an applicable field, or who, by extensive knowledge, training and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter and work.
