This was some fine work facilitated by Lisa Houle at WorkSafeBC (formerly of Brinkman), with contributions from numerous members of the industry and the BC Safe Silviculture Committee. IMHO, the acting and production levels are far above what one might expect from WSBC, and the situation feels very real, and all too familiar.
I think most of us can watch this, and either imagine ourselves in these circumstances or worse, or recall instances of a similar nature.
