Adding an extra buffer in terrain selection to allow for surprises or incorrect assessments.
When dealing with higher danger and persistent or unusual avalanche problems, avalanche forecasts often advise travelers to give themselves a wide buffer or margin for error. This means drawing a line in terrain management where you feel safe and then stepping back from that even further. This might involve choosing lower slope angles, less consequential terrain, denser trees, or a greater distrust with your snow assessments than you might normally be used to. Conditions are such that surprises can be expected, or consequences will be severe if you encounter a rare exception. Wide margins of error are appropriate when avalanches might propagate wider than expected, break dangerously deep, or give no feedback before getting triggered.
