The purpose of this inspection is to ensure that hoses used around the rig are in good working order and used properly.
List each hose with a description of location and purpose so that another worker could locate it. Inspect based on the instructions below and note on the form.
Each hose must be clearly marked with its pressure rating and service limitations. Some hoses may not be rated for high temperature or corrosive materials.
Any hoses that are being used for purposes other than what they were designed for should be addressed.
Carefully inspect each end of the hose to verify the integrity of the connection.
When not in use, hoses should be coiled and stored properly to prevent damage to the body of the hose or to the end fittings.
Third party hose runs should be checked as well to make sure they don’t interfere with rig operations or create unsafe conditions for the rig crew.
Conduct this inspection to ensure that hoses used around the rig are properly snubbed to prevent injury should the fitting fail and the hose whip out of control.
Good practice recommends that hoses longer than 3 feet should have secondary restraint if they are:
List each hose with a description of the location and purpose so that another worker could locate it. Inspect based on the instructions below and note on the form the: hose size and rating, clamp location, attachment point, and condition of whip checks.
Ensure that the chain clamp is installed at the proper location on the hose. Most vibrating/ rotary hoses have the clamp area marked 2 to 3 feet in from the coupling. The small eye on the coupling is for fit up of the connection only and is not a lifting eye and should not be used for secondary restraint. Safety chains should be attached securely to a dedicated pad eye or structural member that can withstand the impact of a sudden failure. Clamps used overhead should be placed where they do not interfere with running lines or tugger hoist lines. Restraints should never be placed around the coupling.
Whip checks are light weight cable devices used for smaller hoses in various applications. Air powered tools that use large volume air hoses should always be equipped with whip checks at each connection. The whip check should be installed before each connection is made and the cable should be installed to minimize the amount of slack in the cable. Whip check cables should not be used to hang hoses nor should they be used for any other purpose than intended. Whip checks should not be used for high pressure, high volume applications where safety chains or cables should be used. Whip checks can be used for moderate pressure less than 200 psi in smaller diameter less than 3 inch hose. Whip checks should be inspected for corrosion or damage.
Be sure to conduct this inspection to make sure that pins and keepers are installed correctly for efficient and safe operation. For more information see: factory specifications from manufacturer.
Note the locations and type of pins and keepers on the rig. Write the quantity inspected for many in one location.
Check that the point taper on the pin is completely through the assembly with the outside diameter of the pin in contact with the internal diameter of the connection.
Check that pins are not so long that they can be bent or otherwise damaged making them difficult or impossible to remove.
Check that the pin head has a stop collar or stop pin to prevent the pin from being driven too far into the connection.
Make sure that the head of the pin is not mushroomed to the point that fragments could be broken off as the pin is being driven. Also inspect the pointed end of the pin for damage caused by excessive hammering.
If the pin must be hammered to the point where mushrooming occurs, the connection is misaligned.
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:
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.
Confirm that the pins are inspected for damage and in good shape prior to installation. If the keeper is in good shape when installed, any damage noted during the inspection would indicate some type of problem or interference. Check that the keeper is not hard against the shoulder of the pin pocket, but is loose and free to move without binding.
Check that the safety bolts are sized to fit the pin safety hole closely, without binding, and without the need for numerous washers.
The bolts should be long enough to get the entire nut onto the bolt with at least 2 threads showing through the nut.
Check that the safety bolt is not installed without nuts, particularly in overhead applications.
