Techniques

Application of specialized equipment used to detect the presence of buried

structures.

Combustible liquid

Any liquid having a flash point at or above 100 deg. F (37.8 deg. C), but below

200 deg. F (93.3 deg. C), except any mixture having components with flash

points of 200 deg. F (93.3 deg. C), or higher, the total volume of which make up

99 percent or more of the total volume of the mixture.

Compressed gas

Any compound that exhibits the following characteristics:

• A gas or mixture of gases having, in a container, an absolute pressure

exceeding 40 psig at 70 deg. F.

• A gas or mixture of gases having, in a container, an absolute pressure

exceeding 104 psig at 130 deg. F. regardless of the pressure at 70 deg. F.

• A liquid having a vapor pressure exceeding 40 psig at 100 deg. F.

Concrete Coring

The cutting of surface concrete so drilling may be conducted in the soil beneath.

This may be done with a circular drill bits or flat saws.

Container

Any bag, barrel, bottle, box, can, cylinder, drum, reaction vessel, storage tank, or

the like that contains a hazardous chemical. For purposes of this section, pipes or

piping systems, and engines, fuel tanks, or other operating systems in a vehicle,

are not considered to be containers.

Core Barrels

A tubular device run in place of a bit and used to cut (collect) a core sample.

Coupling and

Decoupling Augers

The act of joining or separating two augers by adding or removing auger bolts or

screwing/unscrewing the augers.

Critical Areas

The subsurface spaces within ten feet of a structure where items may exist that if

compromised could result in injuries, damaged equipment, damaged property, or

at a minimum, disruption of utility services.

Critical Zones

An area of the drilling site that poses special hazards or increased risk to

personnel.

Cuttings

The fragments of rock and soil dislodged by the bit and brought to the surface in

the drilling mud or by the rotation of the auger.

Decontamination

The act of cleaning equipment to remove unwanted materials or chemicals.

Commonly done by pressure washing, steam cleaning, or hand scrubbing with

soap and water.

Direct Push

A drilling technique that uses percussion hammer or hydraulic ram to push or

hammer various sample tooling into the subsurface, Geotechnical sampling,

continuous soil sampling, in situ groundwater sampling, or small diameter well

installation can be performed with these units.
