Precautions for Setting up and Blocking the Drilling Rig

It is the driller’s responsibility to verify the rig is properly set up. The stability of the drilling rig is

critical to assure safe drilling operations. Some things to consider when setting up are provided below.

Refer to section 4 – TITLE for more detailed information.

• Whenever possible, the driller should choose a dry, level, and reasonably smooth drilling site. Verify

the rig's parking brake is engaged and that the wheels which will remain on the ground are blocked.

Blocking the rig will help to provide a more stable drilling structure by distributing the weight of the

rig evenly. If the rig is equipped with jacks or outriggers, they will be extended from the rig to the

ground, raising the rig partially or entirely off the ground. Proper blocking of the rig will prevent

differential settling which could result in the rig toppling sideways. Blocks should be placed between

the jack swivel and the ground to provide more support area under the pad.

• All drill rig personnel and visitors should be instructed to stand clear of the drill rig immediately

prior to and during starting of an engine.

• Before start-up, check that all brakes are set, all gear boxes are in neutral, all hoist levers are

disengaged, all hydraulic levers or air controls are in the correct position, and the cathead rope is not

on the cathead.

• Follow all guidelines provided by manufacturers with regards to starting up engines.

• Check for warning or lockout tags on the controls. Do not start any engine without having the tag

removed by the person responsible for the install.

• Prior to lowering the leveling jacks, we recommend that a timber or plank be placed beneath the

jack. By performing this function, it will be less likely that the jacks will sink into the ground. Even

on asphalt, jacks could possibly, over time, sink down to the point that the rig might not remain

level. Insure that the rig is level and everything is secured prior to raising the mast. Before the mast

is raised, the rig must be leveled and stabilized with the leveling jacks.

• Verify before drilling is started with a particular drill, that the operator (who may be the safety

supervisor) has had adequate training and is thoroughly familiar with the drill rig, its controls, and its

capabilities.

• Inspect the drill rig when it first arrives onsite and then at least daily for structural damage, loose

bolts and nuts, proper tension in chain drives, loose or missing guards or protective covers, fluid

leaks, damaged hoses, damaged pressure gauges, and pressure relief valves.

• Check and test all safety devices such as kill switches at least daily and preferably at the start of a

drilling shift. Drilling should not be permitted until all kill switches and warning systems are

working correctly. Do not wire around, bypass, or remove an emergency device.

• Verify all gauges, warning lights, and control levers are functioning properly and listen for unusual

sounds on each starting of an engine.

• Verify nothing is loose on the mast that would fall when the mast is raised to its upright position.

When the mast is raised, take measures to secure it properly.
