Running casing into the hole.
Potential Hazards
- hazards are similar to those for drilling ahead or tripping
- getting caught between, struck by, or pinched by the power tongs, casing or other equipment

- falling from the stabbing board or work platform
- getting struck by dropped objects
Danger is built into the job.
Possible Solutions
- Include the casing crew and the drilling crew when conducting a JSA and pre-job safety meeting to coordinate the activities of casing operations.
- Stand clear of suspended, hoisted, or moving loads. Be aware of tubulars or equipment being lifted through the V-door.
- Emphasize all normal worker safety procedures, such as fall protection, PPE, placement of hands and feet, and teamwork and communication between workers.
- Implement full fall protection program for the casing stabber.
- Identify clearance between the stabbing board and casing elevators.
- Secure all items used by the casing stabber overhead with a safety line.
