Department: [DEPARTMENT NAME]
1. Scope
This safe work practice (SWP) outlines the procedures for the safe use of excavator bucket lifting points for rigging and lifting operations. It covers the inspection of rigging and lifting devices, safe load handling practices, and awareness of ground contact hazards. This SWP applies to all personnel involved in lifting operations using excavator buckets with designated lifting points. It does not cover lifting operations that exceed the excavator's rated lifting capacity or any lifting without properly inspected and certified rigging.
2. Definitions
Qualified Rigger A person who, by possession of a recognized degree, certificate, or professional standing, or who by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems relating to rigging and lifting operations. The employer must use at least one qualified rigger to perform the rigging during hoisting activities for assembly, disassembly, or re-configuration work; Whenever employees are engaged in hooking, unhooking, or guiding a load, or in the initial connection of a load to a component or structure. [1]
Rated Load The maximum load a component or piece of equipment is designed to handle. An employer or contractor shall not require or permit the operator of a hoist, crane or lifting device to raise any load that is greater than the rated load determined by the manufacturer of the equipment or a professional engineer for the conditions in which the equipment is to be operated. [2]
Rigging Hardware Equipment such as shackles, links, rings, swivels, and hooks used to connect the load to the lifting device. [1]
Below-the-hook lifting devices Lifting accessories used between the hook and the load. All below-the-hook lifting devices in use must meet the ap- plicable requirements for design, inspection, construction, testing, maintenance and operation as prescribed in ASME B30.20-2021. [1]
3. Responsibilities
3.1 Supervisors
- Ensure that all workers are trained and competent in the safe use of excavator bucket lifting points, rigging, and lifting devices.
- Verify that all rigging and lifting equipment is inspected before use and is in good working condition.
- Conduct pre-lift meetings to discuss the lift plan, potential hazards, and control measures.
- Ensure that the excavator is operated within its rated lifting capacity and that the load is properly secured.
- Monitor lifting operations to ensure compliance with this SWP and other relevant safety procedures.
3.2 Workers
- Participate in training and demonstrate competency in the safe use of excavator bucket lifting points, rigging, and lifting devices.
- Inspect all rigging and lifting equipment before use and report any defects to the supervisor.
- Follow the lift plan and instructions provided by the supervisor and qualified rigger.
- Ensure that the load is properly secured and balanced before lifting.
- Maintain a safe distance from the load during lifting operations.
- Report any unsafe conditions or practices to the supervisor immediately.
3.3 Health and Safety Representative
- Assist in the development and review of safe work practices for lifting operations.
- Conduct regular workplace inspections to identify potential hazards related to lifting operations.
- Investigate incidents and near misses related to lifting operations and recommend corrective actions.
- Promote a culture of safety and awareness regarding lifting operations.
4. Potential Hazards and Risks
| Hazard | Risk | Control Measures |
|---|---|---|
| Failure of rigging or lifting device [1] | Load dropping, causing serious injury or death. | Use only certified rigging and lifting devices with appropriate SWL. Inspect all rigging before each use. The rated load of the rigging equipment must not be excee- ded. |
| Swinging load [7] | Load colliding with workers or objects, causing injury or damage. | Use tag lines to control the load. Ensure a clear path of travel. Do not stand near a load. Position yourself away from and fully clear of the load. Remember to also consider how the load might fall when it lands. |
| Ground contact hazards (underground utilities, unstable ground) [8] | Damage to utilities, excavator rollover, or ground collapse. | Identify and mark underground utilities before digging or lifting. Ensure the ground is stable and level. Inspect the area where the crane/equipment will be set up and look for inadequate surface area; Inadequate support to withstand all force imposed, wind, weather, and unstable conditions; and Other potentially hazardous conditions. |
| Overhead hazards (power lines, structures) [3] | Electrocution, collision, or entanglement. | Identify and maintain safe clearance from overhead power lines. Be aware of overhead structures and obstructions. MNOSHA Instruction STD 1-16.7A Documentation required for citations relating to a lack of PPE shall include voltages that workers are exposed or potentially exposed to, tasks performed (voltage testing, maintenance, etc.) and proximity to live or potentially live parts. |
| Improper rigging techniques [9] | Load slippage or failure, causing injury or damage. | Use correct rigging methods for the load. Ensure proper sling angles and attachment points. A choker hitch only compresses the load on 3 sides whereas a double wrap choker hitch compresses the load on all 4 sides providing better load control. |
| Unqualified or untrained personnel [4] | Incorrect operation of equipment, leading to accidents. | Only trained and qualified personnel are allowed to operate the excavator and perform rigging. Recommended that the operator demonstrates the ability to operate the lifter safely and as outlined above prior to using the lifter. |
| Manual Handling [6] | Back injuries are caused by lifting and carrying heavy materials, working in awkward positions, and bending often to lift materials off the ground. | Whenever possible, use mechanical equipment like a dolly to move heavy objects horizontally. Never try to lift an item weighing over 50 pounds by yourself. Plan your lifts; make sure the path is clear and you are facing the direction of travel before lifting. |
| Equipment Failure [5] | Equipment malfunctions during operation. | Regular inspection and maintenance of equipment. If the inspection of a hoist, crane or lifting device reveals a condition that might render the equipment unsafe or incapable of raising the rated load mentioned in subsection 13-8(2), an employer, contractor or supplier shall not require or permit the use of the equipment until any necessary repairs are completed. |
5. Personal Protective Equipment (PPE)
All personnel involved in lifting operations must wear appropriate personal protective equipment (PPE).
- Hard Hat: Provides head protection from falling objects or impacts.
- Safety Glasses: Protects eyes from dust, debris, and other potential hazards.
- High-Visibility Vest: Ensures the worker is visible to equipment operators and other personnel.
- Gloves: Protects hands from cuts, abrasions, and other hazards.
- Steel-Toed Boots: Protects feet from crushing injuries.
- Hearing Protection: Protects hearing from loud noises.
Inspect all PPE before each use for any signs of damage or wear. Replace damaged or worn PPE immediately. Follow the manufacturer's instructions for cleaning and maintaining PPE.
6. Equipment and Tools
All equipment and tools used in lifting operations must be inspected regularly and maintained in good working condition.
- Excavator: Used for lifting and moving loads. Ensure the excavator is in good working condition and has a current inspection.
- Certified Slings: Used to connect the load to the excavator bucket lifting point. All slings in use must meet the applicable requirements for design, inspection, construction, testing, maintenance and operation as prescribed in ASME B30.9-2021. [1]
- Shackles: Used to connect slings and other rigging hardware. All rigging hardware in use must meet the applicable require- ments for design, inspection, construction, testing, maintenance and operation as prescribed in ASME B30.26-2020. [1]
- Tag Lines: Used to control the load during lifting.
- Measuring Tape/Device: Used to verify load dimensions and clearances.
Regularly inspect all equipment, including the excavator, rigging, and lifting devices, for any signs of damage or wear. Follow the manufacturer's recommendations for inspection and maintenance. An employer, contractor or supplier shall ensure that a hoist, crane or lifting device is inspected by a competent person to determine whether the hoist, crane or lifting device is in safe working condition before the hoist, crane or lifting device is used at the start of each work shift; and at regular intervals as recommended by the manufacturer. [5]
