Ice Drilling Safety and Techniques

The video tutorial provides a comprehensive guide on ice core drilling, covering site selection, drill setup, safety precautions, and the drilling process. It emphasizes the importance of safety measures, such as using a GFI to prevent electrocution and ensuring the drill is held securely. The tutorial also explains how to extract and handle the ice core once drilling is complete.

What is the primary focus of gathering information about the Earth, sky, and oceans?

• To explore marine life

• To study ice formations

• To predict weather patterns

• To map the ocean floor

What should you look for when identifying a suitable ice drilling location?

• A completely smooth and level area

• An area with a lot of snow drifts

• A place with visible cracks

• A spot with thick snow

What material is the core barrel made of?

• Wood

• Fiberglass

• Metal

• Plastic

Why is a safety disc used when drilling with an electric drill?

• To stop the assembly from dropping into the hole

• To increase drilling speed

• To reduce noise

• To prevent the drill from overheating

What is the purpose of a GFI in ice core drilling?

• To provide extra power

• To prevent electrocution

• To stabilize the drill

• To measure ice thickness

What should you always check before starting to drill?

• The ice temperature

• The drill's weight

• The plug's location

• The drill's battery level

How should you hold the drill to ensure safety?

• With one hand

• With gloves only

• With both hands firmly

• With a loose grip

What is a common mistake when handling the drill?

• Holding the drill too tightly

• Using the wrong drill bit

• Not checking the drill's alignment

• Loosely holding the drill and accidentally triggering it

Why is it important to ensure the drill is exactly vertical?

• To reduce noise

• To prevent the drill from overheating

• To ensure a straight and aligned hole

• To increase drilling speed

What should be done occasionally during the drilling process?

• Check the drill's temperature

• Add more water to the hole

• Lift the drill to remove shavings

• Change the drill bit
