A tree care crew is preparing for the day's work, which includes one climber and two ground workers. According to ANSI Z133, what is the minimum requirement for emergency readiness on this crew?
Answer: B. At least one worker on site must be trained in aerial rescue procedures.
ANSI Z133 requires that workers be trained in emergency procedures, including aerial rescue. While having multiple people trained in first aid/CPR is best practice, the standard's critical provision for climbing operations is ensuring that someone on site has the specific training to rescue an injured or incapacitated worker from aloft.
What are the OSHA requirements for training tree care workers regarding electrical hazards?
Answer: B. All tree workers must be trained to recognize and avoid electrical hazards; only qualified line-clearance arborists may work within the minimum approach distance of energized conductors
OSHA requires all tree workers to be trained in electrical hazard recognition and avoidance. Only qualified line-clearance arborists (who receive extensive additional training) are permitted to work within the minimum approach distance of energized conductors.
What role do auxins play in tree growth and development?
Answer: B. They regulate apical dominance, promote cell elongation, stimulate cambial activity, and influence root initiation
Auxins are versatile plant hormones that regulate apical dominance (suppressing lateral bud growth), promote cell elongation in shoots, stimulate the vascular cambium to produce new cells, and influence adventitious root formation.
