Know the gear. Test the safeties.

Arborist climbing lines and rigging lines fail from the inside out. Inspect by feel along every inch, not by eye alone.

The bridge, D-rings and stitching carry the climber. Inspect them at every tie-in and after every hard day.

Auto-locking, load-rated connectors only for life support — and cross-gate loading is what breaks them.

Hitch cords and mechanical devices are consumables — heat, glaze and compatibility drive both inspection and retirement.

PPE is rated for the hazard: electrical class, impact and lateral protection, eye and hearing ratings all have to match the job.

Every safety device on a saw has a daily test, and every injury pattern traces back to reactive forces or a bad body position.

The chipper is the highest-consequence machine on the truck. The panic bar test and feeding discipline are non-negotiable.

Upper and lower controls, the emergency bleed-down, outrigger setup and dielectric condition are the daily tests that keep a boom trustworthy.

A friction brake turns a falling piece into a controlled lower — wrap count, mounting and tailing position decide whether it works.

A mechanical advantage winch with a friction bollard lets a crew lift, hold and lower heavy wood with no shock load at all.

Sheave diameter, WLL and a sound attachment decide what a block can take — and shock loads multiply everything.

Adjustable slings and shackles are the quiet link in a rigging system — splice burial, screw pins and bend radius all matter.
