Which statement about arborist safety standards is accurate in the United States?

• A. NFPA standards
• B. ANSI Z133 Safety Standards for Arboricultural Operations
• C. ISO safety guidelines
• D. OSHA only

Answer: (B)

Safety in tree work is guided by a standard created specifically for arboriculture. The best-supported reference in the United States is ANSI Z133 Safety Standards for Arboricultural Operations. This standard lays out detailed requirements for climbing, rigging, tool use, personal protective equipment, equipment inspection, and safety programs, giving crews a concrete framework to reduce risk on the job. Other options exist, but they don’t target arboriculture as directly: NFPA standards cover broader safety topics like electrical and fire protection; ISO guidelines are international and not the primary US reference for tree work; OSHA provides general workplace safety rules rather than a dedicated arborist standard. So ANSI Z133 is the accurate reference for arborist safety in the United States.
