General Servicing Precautions for Wells
Working on an existing well to restore or increase oil and gas production is an important part of today’s petroleum industry, yet these operations present many occupational hazards for workers. The following list highlights potential hazards and safety solutions to promote a hazard-free work environment.
Removing the Horsehead
- Unit starts up while working on the equipment.
- Being struck by counterweights on the pumping unit.
- Being struck by a dropped horsehead or caught between the horsehead and walking beam.
- Falling from high elevations.
- Use lockout/tag out to mechanically secure the flywheel.
- Inspect all slings before use.
- Use tag lines to position the horsehead when removing or lowering, and to keep employees clear of suspended loads.
- Use the correct tools for the task at hand.
- Keep fingers and hands away from pinch points.
- Secure tools from falling, and keep areas below clear of others.
- Use proper personal protective equipment (PPE) and abide by the fall protection program.
Removing the Wellhead and Pulling and Running Rods
- Being struck by released pressure or flying particles.
- Being struck by the wrench or hammer while removing bolts and fittings.
- Getting caught between the wellhead, hydraulic wrenches and wellhead fittings.
- Getting your fingers and hands pinched and caught between flanges and valves.
