A straight ladder that is positioned too steeply can fall over. If it is too flat, it might slip away. Use the elbow method to select the correct inclination angle. This lets you achieve the recommended contact angle of 70°.
- Position yourself with one foot on one of the ladder side-rails so that your foot and the ladder steps are pointing in one direction
- Bend the arm facing the ladder and raise it (so your hand is at approximately chest height)
- If your elbow touches the ladder, you are standing correctly
