The gap is training.

Tree care is one of the most dangerous occupations in the U.S. The pattern is consistent.

23%
of tree-worker fatalities involve workers with less than 1 year of experience — the single most preventable risk in the industry

"This isn't about compliance paperwork. It's about the worker who goes home."

When OSHA shows up — or when an incident happens — the question isn't whether you care about safety. It's whether you can prove it. Documented, standards-based training is the difference between a defensible record and an exposed liability.

Every hazard has a paper trail — or it doesn't.

The difference between a defensible incident and an exposed liability is often documentation.

Every tool your safety program needs

Purpose-built for tree service operations — not adapted from generic training software.

Our Difference

ANSI Z133 Clause-Level Training

Every course maps directly to specific Z133 clauses — not generic "safety topics." Know exactly which standard requirement each employee has completed.

Online Training Courses

Structured safety modules employees complete on any device. Each course includes knowledge checks and a scored final quiz before certification.

Certification Tracking

Certificates issued automatically on course completion. Expiration alerts fire 30 days before lapse — before it becomes a compliance gap.

Compliance Dashboard

Real-time view of your entire team's training status. See who's current, who's overdue, and which certifications are expiring — at a glance.

OSHA Incident Reporting

Log incidents and near-misses. Generate OSHA Form 301 and maintain your OSHA 300 log automatically. Built for the audit you hope never comes.

Audit-Ready Compliance Records

Every training completion, certificate, and incident is timestamped and verifiable. When OSHA shows up, your documentation is already organized.

Built on ANSI Z133 — not adapted from it

Other platforms teach "safety." We teach the specific standard that governs your work.

ANSI Z133 — Arboricultural Operations: Safety Requirements

When an OSHA inspector asks what standard your training was based on, "general safety principles" isn't an answer. Z133 is the specific standard they reference for tree care operations — and every Tree Safety Institute course cites the exact clause it covers, so your documentation speaks their language.

Foundation

ANSI Z133 Safety Standard

The national standard for tree care operations. Every module cites the exact Z133 clause it addresses — so your documentation connects directly to the standard OSHA references.
