CATS Safety and ANSI 3

Question 1

ANSI Z133 requires that all arboricultural workers be trained in which emergency procedure before beginning tree work?

Accepted Answer

Cardiopulmonary resuscitation (CPR) and first aid

Answer

ANSI Z133 mandates that all workers involved in arboricultural operations must be trained in CPR and first aid to respond to on-site emergencies.

Question 2

When a climber is performing aerial rescue of an incapacitated worker in a tree, which rigging technique is typically used to lower the victim?

Accepted Answer

Friction hitch descent with a load-releasing hitch

Answer

A friction hitch combined with a load-releasing hitch (such as a Valdôtain tresse) allows the rescuer to control and lower an incapacitated climber safely.

Question 3

Struck-by hazards during tree felling are BEST mitigated by establishing an escape route at what angle relative to the planned felling direction?

Accepted Answer

45 degrees to the rear, away from the intended felling direction

Answer

ANSI Z133 recommends an escape route at approximately 45 degrees to the rear of the intended felling direction to avoid the butt kickback zone.

Question 4

Which ANSI standard specifically governs the design and performance requirements for tree care equipment such as aerial lift devices?

Accepted Answer

ANSI A92.2

Answer

ANSI A92.2 covers vehicle-mounted elevating and rotating aerial devices, establishing design, testing, and performance standards for aerial lifts used in tree care.

Question 5

A drop zone established during a tree removal operation should extend at minimum how far from the base of the tree in all directions?

Accepted Answer

Equal to the full height of the tree

Answer

Best practice and ANSI Z133 guidance recommend a drop zone extending at least the full height of the tree to account for bounce and roll of cut sections.
