How to Self Arrest
When it comes to survival situations, self-arresting is a crucial technique that can save your life in case of an unexpected snow or ice slide. It’s essential to understand the proper techniques and equipment to self-arrest to prevent injuries or fatalities.
What is Self Arrest?
Self-arrest, also known as falling-slowly, is a technique used to prevent an individual from sliding out of control on snow or ice. It involves anchoring yourself to the terrain by using your body or an ice axe to halt the descent. Self-arresting is a common method used by mountaineers, skiers, and snowboarders who venture into areas with icy or snowy terrain.
How to Self Arrest?
To self-arrest correctly, follow these steps:
- Position: If you find yourself sliding down an icy or snowy slope, position your body into the slope to slow down. Try to get as perpendicular to the slope as possible to reduce your velocity.
- Anchor point: Look for an anchor point, such as a rock, tree, or steep wall, to hook onto with your ice axe. This will help stop your descent.
- Pull yourself up: Slowly pull yourself up by hand, using your gloved hands to grip your clothes or the anchor point.
- Dig: As you pull yourself up, dig your ice axe into the snow or ice at an angle, so that it acts as an anchor to stop your motion.
Equipment Needed for Self Arrest
To perform a self-arrest effectively, you’ll need:
- Ice axe: A sturdy ice axe is essential for self-arrest. Look for an axe with a curved or angular shaft, which provides a more secure grip.
- Gloves: Wear insulated and waterproof gloves to improve your grip and prevent moisture buildup.
- Rental gear: If you’re renting equipment, ensure the ice axe has a secure strap that fits snugly around your wrist to prevent it from slipping off.
How to Choose the Right Location
When choosing a self-arrest location, look for:
- Clear landing: Ensure the location you choose has a clear landing, free from any obstacles or hazards.
- Good anchor points: Identify sturdy anchor points, such as trees or rocks, to attach your ice axe.
- Shallow snow or ice: Opt for an area with shallow snow or ice to reduce the likelihood of post-holing.
Self Arrest Techniques: The Slide-Control Method****
The Slide-Control Method involves anchoring yourself with an ice axe and a controlled descent:
- Ice axe positioning: Hold your ice axe with the flat blade facing downwards, so it can dig into the snow or ice.
- Anchor point: Reach forward with your free arm to find an anchor point, such as a tree branch or rock.
- Slow descent: Use your legs to control the pace of your descent, digging your ice axe in periodically to slow down your slide.
Common Errors and Precautions
Common errors to avoid include:
- Not testing anchor points: Always test your anchor points before descending to ensure their stability.
- Slacking off: Maintain proper position and control throughout the descent, as slacking off can lead to unintended sliding.
- Misplacing ice axe: Be cautious when placing your ice axe, as misplacement can result in loss of control.
Conclusion
Self-arresting is a vital skill for individuals venturing into snowy or icy terrain. By following these steps, using proper equipment, and choosing suitable locations, you can learn how to self-arrest effectively and prevent accidents or injuries.
