3.6 - Preparing for Drilling

3.6.1 - Preparing the Site

Prior to drilling, adequate site clearing and leveling should be performed to accommodate the drill rig and

supplies and provide a safe working area. Drilling should not be commenced when tree limbs, unstable

ground, or site obstructions cause unsafe drilling conditions. Housekeeping should be done to ensure a clear

area for all site personnel.

Prior to move-in, the site should be adequately cleared and leveled to accommodate the drilling equipment

and supplies, and to minimize fire hazards.

Evaluate the drilling site prior to setting the leveling jacks, especially if the location is on water saturated,

frozen, or loose, caving soil. Do no set up on sloped ground. If necessary, build up solid, compacted earth

where the jacks will contact the ground.

Job site should be on level ground (recommended no more than 5% grade), with solidly compacted soil to

support the drill rig and auxiliary equipment. If it is necessary to work on a slope, the rig should be backed

perpendicular to the slope so at least the rig is level left to right and the driller's platform is closer to the

ground.

If it is necessary to drill within an enclosed area, verify that exhaust fumes are conducted out of the area.

Exhaust fumes can be toxic and some cannot be detected by smell.

3.6.2 - Traffic Control

Traffic control devices may consist of items such as:

• Traffic cones

• Flags

• Caution tape

• Other devices such as signs, barricades, amber flashing lights, or fencing

It is recommended that each work area be cordoned off with traffic cones or other traffic control devices as

appropriate to site-specific conditions. To increase visibility to vehicular traffic, it is recommended that

every other cone have a flag inserted through its middle. Caution tape should be used to join all of the traffic

control devices so that no one can easily walk through the work area. It is also recommended that work

vehicles be used to shield field personnel from traffic hazards when practical. In addition, high-visibility

clothing should be worn by workers.
