Working at Heights and Slopes

Terrain hazards require awareness and proper techniques. Slope Stability Assessment Warning Signs - Fresh cracks or scarps - Leaning trees or poles - Seeps or springs - Recent rainfall Unstable Materials - Loose talus - Undercut slopes - Clay-rich soils when wet - Decomposed rock Safe Practices - Plan routes on stable ground - Test footing before committing weight - Face the slope when descending steep terrain - Use three points of contact - Work uphill of partner to avoid rockfall Cliff and Outcrop Work - Identify fall hazards - Test rock stability before climbing - Wear helmet - Partner system for difficult exposures - Consider rope work for extreme terrain
