These new and updated webinars provide Electrical Hazard Awareness education in three 1-hour sessions. 

All arborists must be trained to recognize and avoid electrical hazards. This on-demand webinar covers a wide range of safety-related topics essential for arborists working near energized overhead power lines, presented by the tree care industry’s leading safety expert – Dr. John Ball.

Critical topics addressed in this webinar include:

How electricity works

Basic terminology

Current standards & regulations

Electrical hardware identification

Hazard assessment

Estimating nominal voltage 

Line clearance pruning practices to reduce exposure

Recent incidents involving tree workers & electrical conductors

Emergency response to electrical contact incidents involving workers who are aloft

Completion of the course satisfies one major OSHA requirement for arborists working 10 feet or closer to energized conductors.  Additional employer-verified proof of aerial rescue training and CPR/First Aid are required to fully meet OSHA’s electrical hazards awareness certification standards.

MAA will issue a Certificate of Attendance to participants who watch the full 3-hour course and complete the follow up quiz.  Your certificate of attendance will come from the MAA office.
