Most arborists work in cities, but rural work is becoming more common. They work outdoors in crews of 2 to 6 people, often throughout the year, with some time indoors doing paperwork. They may work long hours in spring and summer, and after storms or emergencies.

Arborists use hand and power tools. They also use specialized pruning tools and pesticide-application equipment. They must avoid injury when working with tools, machinery, chemicals, and electrical hazards such as power lines. Their work involves climbing, bending, twisting, and lifting and can be physically demanding.

Under Part 39 of Alberta’s Occupational Health and Safety Code [pdf], employers must develop and implement safe work practices and procedures that include:

  • Assessing hazards at the worksite
  • Training workers, including hazard recognition
  • Selecting, limiting, operating, and maintaining tools and equipment
