A tree harvesting plan should be developed to address the hazards associated with a specific logging site. Hazards to consider in developing the plan include: (a) Overhead hazards including electric lines, (b) Danger Trees including Stubs, Spring Poles, Wind Blowns, and Widow Makers, (c) General Environmental and Working Conditions, (d) Adequate separation of operations while maintaining visual or audible contact. What are the general safe practice requirements? (a) Employees must be spaced and the duties of each employee must be organized so the actions of one employee will not create a hazard for any other employee. (b) Assess for and limit hazards associated with electrical storms, strong winds which may affect the fall of a tree, heavy rain or snow, extreme cold, dense fog, fires, mudslides, and darkness. (c) Trees must be felled in a manner that does not create a hazard to employees ( i.e. work areas must be assigned so that trees cannot fall into an adjacent occupied work area). (d) Generally, employees must not approach a feller or mechanical felling operation any closer than 2 tree-lengths of the trees being felled, until the feller or felling machine operator has acknowledged that it is safe to do so. (e) Felling must be done uphill from or on the same level as previously felled trees. This will limit the hazards associated with the rolling or sliding of logs or trees. (f) Each employee performing a logging operation at a logging work site must work in a position or location that is within visual or audible contact with another employee. (g) The employer must account for each employee at the end of each workshift. What precautions must be taken when "danger trees" are in the felling area? (a) Each danger tree must be felled or removed using mechanical or other techniques to minimize employee exposure before work is begun in the area of the danger tree. (b) Before felling or removing a danger tree, loose bark and damage must be removed or held in place. (c) If the danger tree cannot be felled or removed, it must be marked and there shall be no work allowed within 2 tree-lengths of it, unless the employer demonstrates that a shorter distance will not create a hazard for an employee. (d) When cutting a spring pole or other trees under stress, no employee other than the feller must be within 2 tree-lengths of the tree when the stress is released
