Details of Incident / Close Call: 

A worker was walking into a 1993-harvested clearcut block to assess the need for brushing. He was carrying a brush saw but it had not been started. It recently stopped raining on the block which averaged a slope of 60% and the worker was slowly making his way up the block by walking across and up the slope.

While walking along, the worker stepped on the stump of a previously harvested tree. He did not notice the degree of center rot and the stump gave way, causing the worker to hyperextend his left knee.

Learnings and Suggestions: 

When walking within a cutblock, ensure that both proper footing and balance is established and maintained at all times. Remind yourself that, over time:

1. Coarse, woody debris such as stumps and logs continue to deteriorate and become increasingly unstable.

2. Bark easily separates from the log, especially during wet weather conditions.

3. Woody and herbaceous vegetation can make it difficult to find proper footing. It is important to take your time and establish proper footing when walking through thick vegetation.
