Log lifting sling inspections: 6 checks before the lift

Key takeaways: what to check today

• Daily checks are distinct from periodic exams. A daily inspection by a qualified person is required before use, which is separate from the maximum 12-month interval for thorough inspections of alloy steel chain slings California DIR / Cal-OSHA California DIR / Cal-OSHA.
• Pre-use checks do not replace thorough examinations. Lifting accessories do not normally need formal inspection if proper pre-use checks are made and they undergo their standard thorough examination HSE.
• Track sling identity with your own IDs. You can assign your own serial- or unique ID numbers and assign in which department or location the sling or lifting equipment is located Unirope.
• Record location changes if slings move. You can change the location if the sling moves around within your plant or within your company Unirope.
• Retain specific repair and inspection data. You have a record of all inspection and product repairs done by Unirope, who tested it, what was repaired, why, and when Unirope.

What the six checks cover

Check 1 matches the sling to its record. Check 2 covers inspection status, including the daily inspection by a qualified person before use and any separate periodic examination. The third check records visible damage and whether the sling was removed from service. The fourth check documents temperature exposure specific to the sling material, as different materials have different limits. The fifth check identifies the qualified examiner and the examination report. The sixth check retains inspection and proof-test evidence. These six editorial checks ensure the record is complete and traceable. The daily inspection by a qualified person is a specific requirement under California rules, not a universal standard for every jurisdiction. The other checks are organized to support this requirement and provide a clear audit trail. The record should link the sling’s identity to its inspection history, damage findings, and any removal from service. This sequence is an editorial organization designed to help the supervisor verify that all necessary checks are complete before the lift. The daily check is the most immediate action, while the other checks provide context and historical data. The record should be clear enough to show that the sling was inspected, any damage was noted, and the sling was either approved for use or removed from service. The retained evidence check ensures that the records are available for review. This organization helps the supervisor maintain a clear and defensible record of sling inspections. The record should be updated each day and retained for future reference. The supervisor should review the record before the lift to ensure that all checks are complete and that the sling is approved for use. This process helps prevent the use of damaged or improperly inspected slings. The record should be specific to the sling and its material, and should include the date, time, and name of the qualified person who performed the inspection. The damage findings should be detailed, and the removal from service should be clearly noted.

Checks 1–2: sling identity and inspection status

Check 1: Identify the sling and its record. Before the lift, match the physical sling to its documentation. Unirope’s repair and inspection service allows you to assign your own serial or unique ID numbers to the sling. It also lets you assign the department or location where the sling is located, and you can change that location if the sling moves around within your plant or company, according to Unirope. This identifies the specific piece of equipment in your inventory.

Check 2: Check daily and periodic inspection status. Verify the timing of inspections against the sling’s history. Each day before being used, the sling and all fastenings and attachments shall be inspected for damage or defects by a qualified person, according to California DIR / Cal-OSHA. Additional inspections shall be performed during sling use, where service conditions warrant, according to California DIR / Cal-OSHA. For alloy steel chain slings, thorough inspections shall in no event be at intervals greater than once every 12 months, according to California DIR / Cal-OSHA. Each employer shall make and maintain, for the service life of the sling, a record of the most recent month in which each alloy steel chain sling was thoroughly inspected, and shall make such record available for examination by the Division upon request, according to California DIR / Cal-OSHA.

Lifting accessories do not normally need formal inspection, provided that proper pre-use checks are made and they undergo their standard thorough examination, according to HSE. Your record should show both the daily check and the periodic thorough examination to confirm the sling is cleared for use.

For the daily line, use the Construction Daily Log Checklist for Supervisors beside the sling record.

Checks 3–4: damage and material-specific temperature limits

Record visible damage by documenting the immediate removal of the sling from service. California Code of Regulations, Title 8, Section 5043. Inspections states that damaged or defective slings shall be immediately removed from service, according to California DIR / Cal-OSHA. Your log entry must show that the sling is out of use, not just that damage was seen. For chain slings, CCOHS specifies that hooks should be removed from service if they have been opened more than 15% of the normal throat opening, measured at the narrowest point, or twisted more than 10° from the plane of the unbent hook, according to CCOHS. These criteria apply specifically to the hook component of chain slings as described in the CCOHS: Materials Handling - Chain Slings guidance. Do not apply these hook rejection thresholds to synthetic web slings or other sling materials.

Temperature exposure limits vary by sling material. For chain slings, CCOHS advises to reduce the load limit when using chains in temperatures above 425°C (800°F), according to CCOHS. This temperature threshold is specific to chain slings and does not apply to synthetic materials. For nylon and polyester slings, CCOHS notes that sunlight, moisture, and temperatures above 90°C (194°F) or below -40°C (-40°F) damage both nylon and polyester slings, according to CCOHS. When recording temperature exposure for synthetic slings, note if the sling has been stored or used in conditions exceeding these limits. CCOHS also directs to keep an inspection record for each sling, according to CCOHS. This record should include the specific damage found and the temperature exposure history for that individual sling.

Editorial recommendation: Mark the sling as removed from service in your daily log the moment you identify damage or defects. Do not leave the sling in the active inventory until a qualified person reviews it.

Check the sling material type before applying temperature limits. Chain slings have different thresholds than nylon or polyester slings. Record the specific material and the temperature conditions the sling has experienced. If the sling has been exposed to temperatures above the stated limits for its material, note this in the inspection record. For chain slings, note if temperatures exceeded 425°C (800°F). For synthetic slings, note if temperatures exceeded 90°C (194°F) or fell below -40°C (-40°F). Keep the inspection record for each sling as directed by CCOHS.

Select one sling today and check its material type. Look for visible damage on the sling body and hooks. If it is a chain sling, check the hook throat opening and twist. If it is a synthetic sling, check for damage from sunlight, moisture, or temperature extremes. Record the findings and remove the sling from service if damage or defects are found. Give the record to the qualified person for review. If the lift is for concrete cutting or grinding, record those controls with Concrete grinding controls: 5 checks to record and Silica-control records: 5 fields for concrete work.

Checks 5–6: qualified examination and retained evidence

Check 5: Identify the qualified examiner and examination report Verify that the examination report contains the required details. The Health and Safety Executive (HSE) states that there is no longer a defined format or form for such a report, provided that all 11 items listed in the Schedule are included, according to HSE. This means the report structure is flexible, but the content must cover the specific items outlined in the regulatory schedule. When reviewing the file, confirm that the examiner’s identity and the examination date are clearly documented. If the report lacks any of the 11 scheduled items, the record is incomplete under HSE guidance. For California alloy steel chain slings, the focus shifts to the proof test certificate rather than a general examination report format. The employer must retain a certificate of the proof test for the service life of the sling, according to California DIR / Cal-OSHA. Do not assume that a generic inspection sheet replaces the specific proof test certificate required for alloy steel chain slings in California.

Check 6: Retain inspection and proof-test evidence Maintain a complete archive of all inspection and repair records. Under HSE guidance, examination and inspection records do not need to be kept in hard copy form, but you should be able to provide a written copy when necessary, such as upon request by the relevant enforcing authority or when lifting equipment leaves your undertaking under hire, use elsewhere, or second-hand sale, according to HSE. This flexibility allows for digital storage, but the ability to produce a written copy remains a strict requirement. In California, the requirement is more specific regarding the proof test. The employer shall retain a certificate of the proof test, for the service life of the sling, and shall make it available for examination by the Division upon request, according to California DIR / Cal-OSHA. This means the certificate cannot be discarded after the initial test; it must be kept for the entire duration the sling is in service.

Sling record requirements from each source

The following table organizes the specific recordkeeping and inspection requirements by their issuing body.

Review this table against your current site rules to confirm which specific jurisdictional requirements apply to your equipment. Match the sling material to the correct row before proceeding with your daily checks.

Illustrative example: one chain sling before the lift

A supervisor logs one alloy steel chain sling before a materials lift. The record places it in department 4 and shows the most recent thorough inspection month inside a 12-month interval. The hook is opened more than 15% of the normal throat opening, so the sling is removed from service for that damage. A second note says the chain was used above 425°C (800°F). The record shows a reduced load limit and does not remove the sling for heat alone. A nylon sling is a separate row: heat above 90°C is logged as damage, and so is cold below -40°C. The proof-test certificate is missing, so the gap is marked for the qualified person who does the daily inspection.

Today’s next step: review the existing record and mark unresolved gaps

Select one sling from your current inventory and locate its latest inspection record. Match the sling’s identity to that record to confirm it is the correct item. Check whether the sling is currently in use or removed from service. Under California rules, each day before being used, the sling and all fastenings and attachments shall be inspected for damage or defects by a qualified person, according to California DIR / Cal-OSHA. If the record shows no recent inspection or lists unresolved damage, do not use the sling. Give the item and its record to the qualified person for review. Mark any gaps in the documentation clearly so the next supervisor knows the status. This step keeps the removal record clear and ensures the daily check aligns with the required qualified-person inspection.

FAQ about what to record for lifting sling inspections before a construction materials lift

Does a daily sling check replace a periodic examination?

No. California rules require a daily inspection by a qualified person before use, but they also set a maximum interval for thorough inspections of alloy steel chain slings. According to California DIR / Cal-OSHA, the daily check looks for damage or defects. According to California DIR / Cal-OSHA, thorough inspections of alloy steel chain slings must occur at intervals no greater than once every 12 months. The daily check does not satisfy the periodic thorough inspection requirement.

Who should inspect a sling before use?

A qualified person must perform the daily inspection. According to California DIR / Cal-OSHA, each day before being used, the sling and all fastenings and attachments shall be inspected for damage or defects by a qualified person. This requirement applies to the daily pre-use check.

What records does California require for alloy steel chain slings?

Employers must maintain a record of the most recent month in which each alloy steel chain sling was thoroughly inspected. According to California DIR / Cal-OSHA, each employer shall make and maintain, for the service life of the sling, a record of the most recent month in which each alloy steel chain sling was thoroughly inspected. This record must be available for examination by the Division upon request. The rule specifies the content (most recent month of thorough inspection) and the retention period (service life of the sling).

Do nylon, polyester and chain have the same temperature guidance?

No. Temperature limits differ by sling material. According to CCOHS, load limits should be reduced when using chains in temperatures above 425°C (800°F). According to CCOHS, sunlight, moisture, and temperatures above 90°C (194°F) or below -40°C (-40°F) damage both nylon and polyester slings.

Must HSE examination records always be kept on paper?
