What Does Line Clearance Certified Mean?

Ongoing training is vital in order for Eastside Tree Works to safely provide customers in Seattle, the Eastside, Snohomish and North Bend with quality tree care. This is why several of our certified arborists, foreman and tree experts have completed the necessary training to become Line Clearance Certified.

Who provides the training?

Our employees obtained their certification through ACRT Arborist Training.  The ACRT stands for Assessments, Consulting, Representation and Training.  Founded in 1985, the ACRT is the largest licensed arboriculture vocational training organization in the industry teaching top practices and safety standards.

Employee-owned, they provide training courses taught by experienced industry professionals.  Their goal is to make tree care safer for all workers in the industry.

This course is the only national line clearance certification program in the U.S. Once completed, it satisfies OSHA’s electrical safety training requirement for students.

A 5-day course with a minimum of 40 hours, it was developed specifically for tree workers whose person, tree or equipment comes within the 10’ safety zone around energized wires.  Once completed, our workers will be able to perform their jobs safely, which helps us and our customers.
