CATEGORY INSPECTION ITEMS PASS FAIL N/A
ACTION
NEEDED
General
Drill rig meets regulations for transport on state/federal highways
(inspection sticker, license plate, etc.).
Documentation available to verify that rig was inspected prior to arriving at
ExxonMobil job sites.
Does the rig size meet job requirements?
Maintenance log available for previous 3 months to confirm proper
maintenance/inspection.
Exhaust
Exhaust system should be free from defect and routes engine exhaust
away from drill rig workers.
Fuels
Fuel stored in an approved and properly labeled container.
Fuel transfer lines free from signs of excessive wear and not leaking.
Refueling and transferring of fuel is performed in an approved area with
sufficient containment to prevent spillage.
Exclusion/
Work Zones
The exclusion/work zone is centered over the borehole and the radius
equal to or greater than the height of the mast (measured from ground
level).
The exclusion/work zone should be clear of tripping hazards.
Overhead
Obstructions
Except where electrical distribution and transmission lines have been de-
energized and visibly grounded, drill rigs will be operated proximate to
under, by, or near power lines in accordance with the following:
* 50 KV or less - minimum clearance of 10 feet
* 50 KV or greater - add 0.4 inches for every KV over 50 KV
* If voltage is unknown, maintain at least 20 feet of clearance.
While the rig is in transit, clearance from energized power lines will be
maintained as follows:
* Less than 50 KV - 4 feet
* 50 thru 365 KV - 10 feet
* 366 thru 720 KV - 16 feet
Rig Repairs
Repairs, when possible, are conducted offsite to reduce the risk of any
onsite incidents.
Specialized
PPE
When working at elevated heights, workers are to wear a fall restraining
device attached in a manner to restrict fall to less than six feet.
When working in wet/slippery conditions, all workers have a lug-type sole
or similar slip resistant sole, on their safety footwear to prevent slipping.
