Term Definition

Flammable and

Combustible

Material

Flammable and combustible liquids are liquids that can burn. They are classified,

or grouped as either flammable or combustible, by their flashpoints (the

temperature at which they start to burn). Generally speaking, flammable liquids

will ignite (catch on fire) and burn easily usually at normal working temperatures.

Combustible liquids have the ability to burn at temperatures that are usually

above working temperatures. Flammable material is designated by a flashpoint of

under 100

F and combustible material is designated by a flashpoint between 100

F and 200

Grouting

To fill the annulus between the casing and borehole with liquid slurry of grout

(cement and/or bentonite) and water to support the casing and prevent fluid

migration between permeable zones.

Hoisting Cables and

Ropes

Ropes or metal cables that are used to lift or move augers, casing, and sampling

tools. Usually attached to sheaves on the mast.

Hydraulic Ram

A fluid-pressurized device that pushes casing or sampling tools down.

Job Safety Analysis

(JSA)

A step-by-step breakdown of a task. With each step, the hazard risks and

precautions are identified. A JSA is frequently conducted using a three column

document in which the first column is the step, the second the hazards which may

be potentially encountered and the third column the precautions to take to avoid

the hazard risk. Usually included in, attached to, or referenced by the Health and

Safety Plan.

Kelly

The heavy square or hexagonal steel member suspended from the mast through

the rotary table and connected to the topmost joint of drill pipe to turn the drill

stem. Not for direct push or most hollow stem rigs.

Kill Switch

A safety device, normally a button or toggle stick that will turn off the drill rig

engine when actuated. Usually located in the back of the rig near where the

drilling is conducted.

Mast

A movable derrick capable of being raised as a unit, as distinguished from a

standard derrick, which cannot be raised to a working position as a unit.

MSDS

A Material Safety Data Sheet (MSDS) is a report with descriptions of the

physical properties, compatibilities, hazardous properties and other characteristic

information of a material or chemical. MSDSs are usually attached to the Health

and Safety Plan.

Mud

A liquid that may be used to circulate through the borehole during rotary drilling

and work-over operations.

Non-Indigenous

Material

Gravel or fill dirt that was used as backfill in a previous excavation or boring.

Any material not naturally deposited.
