4.14.2 - Other Fire and Explosion Precautions
• Do not refuel an engine while it is running or while it is still hot.
o Use a funnel when refueling from a can.
o No Smoking while handling or dispensing fuels.
o Fuels should be handled, transported, and stored in approved, properly marked containers.
o Store fuels away from equipment exhaust.
o Do not store fuels inside a building.
• Flammable and combustible materials are typically present at drilling sites.
o These materials include gasoline, diesel fuel, polyethylene, wood, weeds, and others.
o To help prevent these materials from igniting, employees should first and foremost ensure that all
sources of ignition (such as matches or lighters) have been identified and maintained at a safe distance
from flammable and combustible materials.
• Smoking, open flames, or spark producing equipment should not permitted within 75 feet of drilling
rigs, open wells, gasoline-driven pumps, or fuel storage areas.
• Flammable liquids (includes empty and full cans) should not be stored or left within 50 feet of drilling
rigs, pumps, or other related machinery.
• Containers used for fuel will be bonded and grounded during dispensing to prevent the discharge of
static electricity.
• Safety fuel containers must be returned to a designated safe storage area after fueling is completed.
4.15 - Rig Inspections and Maintenance
Drilling contractors are responsible for maintaining the drilling rig in proper working condition. Conducting
routine inspection of the rig and associated support equipment and performing all required maintenance are
key components to ensuring proper working condition. Specific items to consider when performing
inspection and routine maintenance are discussed in greater detail below.
Inspections
The drilling contractor should inspect the drill rig when it first arrives onsite and at least daily thereafter for
structural damage, loose bolts and nuts, proper tension in chain drives, loose or missing guards or protective
covers, fluid leaks, damaged hoses, or damaged pressure gauges and pressure relief valves. Daily
inspections should include the following:
• Inspect and test major systems to ensure proper operating condition and to identify signs of excessive
wear.
o Kill Switches
o Protective Guards
o Cable Systems
o Leveling Jacks and Outriggers
o Drill Controls
o Hydraulic Lines
o Connections, fittings, and valves
o Exhaust Systems
o Brake Systems
• Immediately notify Senior Driller of any equipment or safety device in need of repair.
• Correct all identified equipment and safety device defects prior to drilling.
