Pumping
In this phase of the cementing process, a high-pressure pump is used to force cement down the casing and into the annular space between the casing and the wall of the borehole.
Potential Hazards
- being struck by high-pressure lines or unexpected release of pressure (due to, mismatched or excessively worn hammer unions, line failure)
- being exposed to chemical hazards (such as, silica, toxic liquids, and gases)
- being exposed to high noise levels
- slips, trips, and falls
- overexerting, or receiving sprains and strains while handling materials (such as sacks and buckets)
Possible Solutions
- Direct all non-essential personnel to stand clear.
- Require pump operator to stay by the controls.
- Conduct adequate pressure tests on pump(s) and lines before pumping.
- Hobble high-pressure lines properly to guard against the failure of hose connections .
- Use proper equipment inspection techniques to include hammer unions.
- Wear proper personal protective equipment (for example, respiratory, skin, and hearing) as appropriate for the hazards present.
- Conduct a pre-job inspection to identify, then eliminate or correct hazardous work surfaces.
- Use mechanical lifting aids, proper lifting techniques, and team lifting where appropriate.
