4.16.10 – Work Area Monitoring cont.

Consider the following when using all types of core barrels:

• Use full grip circle wrenches to assemble and disassemble core barrels.

• Keep hands away from the bottom of the core barrel or inner tube when removing it from, or inserting it

into, the casing, augers, or drill rods.

When using a sample extruder (hydraulic ram), consider the following:

• There are two extremely dangerous pinch points that can crush or sever extremities.

o The first pinch point is located at the hydraulic ram, where the ram is inserted into the top of the

Shelby tube. This is typically a tight fit and a potential pinch point.

o The second pinch point area is where the Shelby tubes seats against the front plate.

• The Shelby tube often becomes unseated when retracting the hydraulic ram, which can cause the Shelby

tube to be shoved up onto the ram header and split the metal at the top of the tube causing sharp metal

fragments to be become high-speed projectiles or for the tube to bend abruptly and hit the person operating

the extruder. To prevent this ALWAYS steady the Shelby tube by placing your hand on the mid-portion of

the tube while retracting the ram.

• Use proper lifting techniques when moving this equipment.

• Only trained and qualified personnel should operate sample extruders

• Always use side shield safety glasses or goggles when operating the extruder and operate the extruder

slowly.

• Be aware of pinch points and keep hands and clothing away from these areas.

• When extruding very moist soils, be aware of formation water spraying from the end of the Shelby tube.

• Inspect hydraulic fluid lines of the hydraulic extruder leading to and from the ram assembly for wear or

cuts. If cuts occur, hydraulic fluid could be expelled from a line at high velocity.
