After a 39-year-old Escondido man was killed Monday trimming a palm tree in Bonita, NBC 7 decided to take a deeper look into the world of tree trimmers.
WEST Convention in San Diego Showcases How AI Technology Can Detect and Prevent War and Conflict: Industry ExpertsQuiroz said the 39-year-old husband and father who suffocated to death after fronds fell on him while trimming a tree in Bonita took one of his classes.
Quiroz and fellow instructor Martin Morales showed NBC 7 how trimmers can use an air cannon with 120 pounds of pressure to shoot a lightweight guiding line, with a weight at the end, over the 70 to 100-foot towering trees. According to the trainers, trimmers wear foot spikes and harnesses, similar to mountain climbers, so they can attach to ropes and climb on the outside of the fronds where it’s safer.
As a trimmer prunes the tree on their way up, rotten fronds no longer have support and collapse, Quiroz said.
