Pins and Keepers
Pin Installation
Check that pins are not in an area where they can be impacted by equipment or pipe which may shear the safety keeper and drive the pin out of the connection. For example, pins in the mast across from the racking board may be struck by a lost stand of pipe and driven out of their connection.
In these situations, the pin should be installed so that any impact will drive the pin into the connection rather than out. In addition, the pin should not present a snag hazard for hanging or hoist lines on the rig.
There are generally two types of safety keepers used on assembly pins:
- safety pin
- safety bolt
They should be inspected for proper fit and condition.
Keepers should not have other items attached to them, and should not present a snag hazard.
