Risk management typically involves<br />

six steps (Figure 76). Risk<br />

communication with all stakeholders<br />

is an important part <strong>of</strong> each<br />

step.<br />

Risk <strong>assessment</strong> is regarded as a<br />

continuous iterative process (Figure<br />

77). The monitor <strong>and</strong> review<br />

process is important because<br />

ongoing forest development may<br />

increase the avalanche <strong>risk</strong> over<br />

time. Review gives management<br />

verification as to the success <strong>of</strong> <strong>risk</strong><br />

reduction strategies in use. Continuous<br />

<strong>risk</strong> <strong>assessment</strong> not only<br />

applies to the day-to-day evaluation<br />

<strong>of</strong> snow stability <strong>and</strong><br />

avalanche danger, but also to the<br />

overall avalanche <strong>risk</strong> in an operating<br />

area over time.<br />

Forest managers should watch for<br />

“insidious” <strong>risk</strong>s that may develop<br />

as harvesting moves onto higher,<br />

steeper terrain or, locally, where<br />

steep blocks are harvested above<br />

camps, mills, scales, residential<br />

areas, transportation corridors,<br />

bridges, or power lines.<br />

Once a detailed <strong>risk</strong> <strong>assessment</strong> is complete, an experienced avalanche<br />

practitioner should be consulted to develop a suitable winter safety<br />

program.<br />

Responsibility for Risk Management<br />

<strong>Avalanche</strong> <strong>risk</strong> management is everyone’s responsibility. Risk management<br />

should be integrated <strong>and</strong> owned throughout a company or<br />

operation. A sound objective is to develop a corporate safety culture<br />

above <strong>and</strong> beyond Workers’ Compensation Board requirements. There<br />

should be one, clearly identifiable individual who assesses the overall<br />

situation each day during the avalanche season. That person shall be<br />
