This online Tree Trimming Safety Training course covers safety precautions for tree trimming projects. When tree trimming you may be required to use hand and portable hand tools such as chainsaws, loppers, trimmers to make the required cuts. Aerial lifts may be required to elevate workers to the required heights. All of these tools have the potential to be extremely hazardous. Workers performing these dangerous operations require Tree Trimming Safety Training to help keep themselves and those around them safe.
