- All Engineering Notes shall include all safety precautions, operating, and maintenance procedures, service or duty cycle rating (if applicable), recommended inspection frequency, and complete nameplate data required for the lifting device.
- Where any fixture lifts a load at a point below the center of gravity, the engineering note must explicitly address the issue of the stability of the load and fixture combination.
- All Below-the-Hook lifting devices are subject to the test requirements of ASME B30.20, the manufacturer, and this policy. Operational and Load tests shall be performed using hoisting equipment of the proper size and capacity for the device being tested. Load tests shall be documented in the engineering note.
- Initial Inspection (per Inspection section of this policy) shall be performed and documented in the note.
- D. Review of Engineering Notes: All lifting device Engineering Notes shall be reviewed by a qualified person for compliance with the requirements of this policy.
- E. Amendment of Engineering Notes: All subsequent changes in usage that could affect the safety of personnel or the capability of performance of the lifting device shall require an amendment to the original engineering note. This amendment shall be reviewed in the same manner as the original note.
- F. Similar Lifting Devices: Lifting devices that are manufactured or fabricated to meet previously engineered, fabricated and reviewed lifting devices need not have the full engineering analysis repeated. Documentation shall be provided by reference to an existing approved Engineering Note and the detailing of all differences. A "Rated Load" test shall be required.
- G. Director's Exception: A written exception, signed by the Laboratory Director or his designee, allowing for the use of a lifting device is required for use of a lifting device which does not meet the requirements of this policy.

Specialized commercially manufactured lifting devices which have certificates of test or existing devices which have documented evidence of having successfully passed a load test do not need to be re-load tested. The only deviation to this occurs when the lifting device had been altered, repaired, or modified. In this case a qualified person must be consulted; they may require further testing.
- A. All Below-the-Hook lifting devices shall be inspected in accordance with this policy, ASME B30.20, and the manufacturer’s recommendations.
- B. Initial Inspection - An initial inspection by a qualified person of all new and reinstalled devices is required for commissioning to verify that unit is built and operates to specifications. This inspection shall be documented in the engineering note.
- C. Per Use Inspection - All devices shall be visually inspected by the operator per B30.20 prior to each use. This is not a documented inspection but will cover the following:
- Verification of nameplate, load rating, and validation date of previous annual inspection. The device shall not be used if the nameplate is missing, rated load is insufficient for the lift, or annual inspection is older than one year.
- Surface of the load for debris
- Condition and operation of controls
- Condition and operation of the indicators and meters when installed
- D. Monthly Inspection – A monthly inspection is required for devices with frequent/regular use. It is a visual, non-documented inspection by a qualified person inspecting the following:

- Loose or missing guards, fasteners, covers, stops, or nameplates
- All functional operating mechanisms and automatic hold-and-release mechanisms for maladjustments interfering with operation.
- E. Annual Inspection - An annual inspection must be completed for all devices in use and those to be used that may have been in storage for longer than a 12-month period. The inspection must be documented and records kept by the Supervisor/Foreman and available for review by operators and others requiring access to inspection data and information. The date of the last annual inspection shall be recorded on the lifting fixture. The inspection shall consist of items listed in Monthly Inspection and the following:
- Loose bolts or fasteners
- Cracked or worn gears, pulleys, sheaves, sprockets, bearings, chains, and belts
- Excessive wear of friction pads, linkages, and other mechanical parts
- Excessive wear at hoist hooking points and load support clevises or pins
- F. Infrequently Used Devices
- Stored devices do not require monthly and annual inspections until the device is returned to service.
- An Annual Inspection must be completed prior to use if such an inspection has not been done in the previous 12-month period. If an inspection is required it must be documented, and records kept by the Supervisor/Foreman and available for review by operators and others requiring access to inspection data and information.
- If a device has been inspected in the previous 12-month period then a Per Use Inspection is required prior to use.

All slings shall legibly display the ID as well as the manufacturers load rating tag or be removed from service. All sling ID information shall be recorded on inspection documents.
- D. The rigging qualified person/operator is responsible for ensuring the sling identification is legible and shows the rated capacities for each type of hitch (vertical, basket and choke), prior to each use.
- E. Refer to ASME B30.20, ASME B30.26, and ASME B30.9 for further information on use and maintenance.
- A. Inspections and maintenance of inspection records are the responsibility of the Supervisor/Foreman responsible for the slings.
- B. All slings and rigging hardware are to be visually inspected prior to every use by the operator [29 CFR 1910.184(d)]. Documentation of pre-use inspections is not required.
- C. Periodic, documented inspections shall be conducted on all slings and rigging hardware (ASME B30.9 and B30.26) by a qualified person. Inspection forms are provided in the appendices B and C of this policy. Determination of inspection frequency shall be the responsibility of the Supervisor/Foreman responsible for the slings, but such documented inspections shall be conducted at least annually. The frequency of these inspections is to be based on:
- frequency of use
- severity of service conditions
- nature of lifts being made
- experience gained on the service life of slings used in similar applications
- D. Requirements for pre-use and periodic inspection of slings are contained in ASME B30.9 and 29 CFR 1910.184.
- E. When rigging hardware is in a condition that is questioned by the inspector, a conservative disposal policy should be utilized and the item in question destroyed and discarded.
- F. On occasion, a particular piece of equipment will come with its own rigging. It is permissible to use this rigging as long as the pre-use and annual inspection criteria are utilized for this equipment.
Slings and rigging hardware shall be stored in an area where they will not be subjected to mechanical damage, corrosive action, moisture, and extreme temperatures or kinking. Some slings, when stored in extreme temperatures will experience reduced performance. Further consideration should be made with regard to storage and use in extreme conditions.
