Arborist Practice is independent and not affiliated with the International Society of Arboriculture. These are original Safe Work Practices practice questions written for study. They are not real ISA exam questions, not official ISA material, and not a replacement for the current ISA exam outline, ANSI Z133, employer procedures, or official safety training.
Start with hazard control, not speed
Free ISA Safe Work Practices practice questions are useful because this domain tests judgment under pressure. A question may mention PPE, overhead conductors, a sidewalk, damaged climbing gear, a chainsaw cut, rigging, traffic, or an injured worker. The safest answer usually controls the hazard before production continues.
Use this set as a focused safety drill. Answer all 15 questions before checking the explanations. If you miss several electrical, work-zone, climbing, rigging, or emergency-response items, review the ISA Safe Work Practices exam questions guide before taking another mixed quiz.
For broader prep, use the mixed free ISA Certified Arborist practice questions. If your misses involve tree defects, targets, or mitigation, pair this page with the tree risk assessment exam guide. For full-test pacing, use the ISA Certified Arborist practice test guide after your safety misses stop repeating.
How to take this Safe Work Practices quiz
Treat this as a hazard-reading check, not a score prediction:
- Give yourself 20 minutes for all 15 questions.
- Mark each answer as confident, uncertain, or guessed.
- For every miss, label the hazard type: PPE, electrical, work zone, climbing, aerial lift, chainsaw, rigging, traffic, emergency response, or communication.
- Write the control that should happen before work continues.
- Retest the weakest category, then return to mixed-domain practice.
The ISA Certified Arborist exam outline is controlled by ISA and can change. Use the official ISA Certified Arborist credential page and the exam outline PDF as the source of truth for current domain wording and exam details.
15 ISA Safe Work Practices practice questions
1. Work-zone control
A crew is preparing to prune a street tree over an open sidewalk. Pedestrians are still walking below the work area. What should happen before cutting begins?
A. Start with the smallest branches because they are less dangerous
B. Ask the climber to shout warnings while cutting
C. Establish and maintain a controlled work zone that keeps pedestrians out of the drop area
D. Finish quickly before pedestrian traffic increases
Answer: C. Public exposure must be controlled before work begins. Verbal warnings and smaller cuts do not replace cones, barriers, signage, spotters, closure, or another site control that keeps people out of the drop zone.
2. Electrical hazards
A tree limb is within reach of overhead conductors. The crew is not qualified for line-clearance work, and the utility has not been contacted. What is the safest next step?
A. Use fiberglass-handled tools and continue
B. Stop and coordinate with the utility or qualified line-clearance personnel before work continues
C. Proceed only if the branch and weather are dry
D. Send the most experienced worker because experience removes the electrical hazard
Answer: B. Electrical hazards require conservative control. Dry wood, tool choice, and experience do not remove the need for proper qualification, clearance, utility coordination, or de-energization where required.
3. Damaged climbing line
During setup, a climber finds visible damage on a climbing line. What is the best action?
A. Use the line only for a short climb
B. Tie a knot above the damaged area and continue
C. Remove the line from service and use inspected, suitable equipment
D. Use the line for positioning but not ascent
Answer: C. Damaged life-support equipment should not be used. A short climb or modified use does not make suspect gear acceptable.
4. PPE is not the whole safety plan
A ground worker has a helmet, eye protection, and hearing protection while standing under a climber who is cutting limbs. What is still wrong with the setup?
A. PPE removes the need for an exclusion zone
B. The worker is exposed to falling material and should be kept out of the drop zone
C. The worker needs only gloves to make the position safe
D. The climber should cut faster so the exposure time is shorter
Answer: B. PPE reduces injury risk but does not replace exposure control. Workers should not stand in the drop zone while material is being cut above them.
5. Job briefing
A crew arrives for a removal near a driveway, overhead utility lines, and a public walkway. Which action is most appropriate before tools start?
A. Begin cutting lower limbs while the supervisor reviews the site
B. Hold a job briefing covering hazards, roles, communication, work zones, equipment, and emergency response
C. Skip the briefing because the crew has worked together before
D. Ask the client to watch for pedestrians while the crew works
Answer: B. A job briefing connects the work objective to the hazards and controls. Familiar crews still need shared expectations for utilities, public access, communication, and rescue.
6. Aerial lift setup
An aerial lift is positioned on soft, uneven ground near a curb. What should be checked before operation?
A. Whether the lift is stable and set up according to manufacturer requirements, including outriggers or pads if required
B. Whether the worker can reach by leaning out of the bucket
C. Whether the job can be finished before the lift settles
D. Whether a larger chainsaw would reduce time in the lift
Answer: A. Lift questions often test setup before work at height. Ground stability, equipment inspection, outriggers, pads, slope limits, traffic exposure, and manufacturer instructions matter before the worker elevates.
7. Chainsaw kickback
Which cutting habit most directly reduces kickback risk?
A. Cut with the upper tip of the bar whenever the limb is small
B. Keep two-handed control, stable footing, and avoid contacting material with the kickback zone of the bar
C. Hold the saw away from the body with one hand for reach
D. Disable the chain brake to avoid interruption
Answer: B. Chainsaw questions usually reward control, footing, body position, and awareness of the bar's kickback zone. Reaching, one-handed cutting, and disabling safety features increase risk.
8. Rigging and lowering zone
A ground worker walks into the lowering zone while a climber is ready to cut a rigged limb. What should the climber do?
A. Cut a smaller piece so the worker is less exposed
B. Stop the operation until the worker is clear and communication is restored
C. Ask the lowering worker to hold the rope tighter
D. Continue if the limb is not heavy
Answer: B. The lowering zone must be clear before the cut. A lighter piece can still swing, drop, or shock load the system. Communication and worker position come before production.
9. Stored energy in wood
A chainsaw begins to bind while cutting a storm-damaged limb under tension and compression. What should the arborist consider first?
A. Stored energy and how the limb may move when fibers release
B. Whether fertilizer would reduce limb weight
C. Whether cutting faster will remove the hazard
D. Whether PPE makes any cut sequence acceptable
Answer: A. Bent, loaded, or storm-damaged wood can move unexpectedly. The safe decision accounts for tension, compression, bind, escape path, worker position, and the likely movement of the material.
10. Traffic control
A pruning crew is working next to a lane of traffic with poor visibility around a curve. What is the best exam-style response?
A. Place the chipper partly in the lane because drivers can go around it
B. Use appropriate traffic control or delay the work until the lane, workers, and public can be controlled safely
C. Ask one worker to wave at cars while the saw is running
D. Work only during the loudest chipper operation so drivers notice the crew
Answer: B. Roadside work requires traffic control that matches exposure. Visibility, stopping distance, worker position, equipment staging, signs, cones, flaggers, lane closure, and local requirements may all matter.
11. Emergency rescue planning
Before a climber leaves the ground, what should the crew know?
A. Only which branch will be cut first
B. How an injured climber or worker would be rescued, who calls emergency services, and how responders access the site
C. Whether the client has seen similar work before
D. Which worker can climb fastest if something goes wrong
Answer: B. Rescue planning is part of safe setup. Crews should know roles, site address, access, first-aid resources, rescue method, and how to avoid creating a second victim.
12. Electrical contact response
A branch, tool, or piece of equipment may be in contact with an energized conductor. A worker is nearby and may be injured. What is the safest response?
A. Pull the worker away immediately with bare hands
B. Keep others away, call emergency services and the utility, and wait until the electrical hazard is confirmed controlled
C. Spray water to cool the equipment
D. Use a metal pole to move the conductor away
Answer: B. Electrical-contact response is conservative because rescuers can become victims. Do not touch the worker, equipment, or conductor until qualified personnel confirm the hazard is controlled.
13. Communication during rigging
A climber, lowering worker, and ground crew are removing a limb over a fence. Signals are unclear and the climber is not sure the lowering worker is ready. What should happen?
A. Cut anyway because the lowering worker will react
B. Stop until commands, roles, and readiness are clear
C. Drop the piece without using the rope
D. Increase the piece size so fewer cuts are needed
Answer: B. Unclear communication is a safety problem. Rigging depends on shared commands, worker position, load path, and timing. If readiness is uncertain, stop and reset.
14. Chipper safety
A worker is feeding brush into a chipper while another worker stands close to the infeed area with loose clothing and no eye protection. What is the best correction?
A. Continue if the brush is small
B. Move the exposed worker away, correct PPE and clothing hazards, and follow safe feeding procedures
C. Increase chipper speed so the brush clears faster
D. Ask the worker to look away from debris
Answer: B. Chipper questions test exposure control, PPE, clothing, body position, communication, and safe feeding. Small material does not remove the hazard around the infeed and discharge areas.
15. Weather and stopping work
A crew is scheduled to climb and rig in worsening wind and lightning is reported nearby. What is the safest decision?
A. Continue because the schedule is already set
B. Keep working but make smaller cuts
C. Stop or postpone the work until weather hazards are controlled
D. Move faster so the job ends before the storm arrives
Answer: C. Weather can change the risk profile of climbing, rigging, electrical exposure, visibility, and emergency response. The safe answer controls the hazard, even when that means delaying the work.
Score guide
Use the score to choose the next study action:
- 13-15 correct: Safe Work Practices is probably not your main leak. Review uncertain answers, then test tree risk, pruning, or trees and construction because safety logic often appears inside those domains.
- 9-12 correct: You know the general safety pattern but still miss applied judgment. Review the weak hazard category, then take another focused safety set.
- 0-8 correct: Pause mixed mocks. Relearn PPE, work-zone setup, electrical hazards, climbing equipment, aerial lifts, chainsaws, rigging, traffic control, communication, and emergency response before continuing.
A short quiz cannot predict your real exam score. The useful signal is the pattern. Missing three electrical questions is different from missing three PPE or work-zone questions.
What Safe Work Practices questions usually test
Safe Work Practices questions usually test whether you notice the uncontrolled hazard before choosing the work step:
- Electrical hazards: Can you stop work and involve qualified people instead of improvising near conductors?
- Work-zone control: Can you protect pedestrians, workers, vehicles, and property before material falls or swings?
- Equipment and PPE: Can you distinguish required protection from the larger safety system?
- Climbing, lifts, and rigging: Can you inspect gear, control load paths, clear zones, and restore communication before cutting?
- Emergency response: Can you avoid making the incident worse, especially around electricity, traffic, and injured climbers?
If an answer puts speed, convenience, or habit ahead of hazard control, be skeptical.
Where to go next
If electrical hazards, PPE, work zones, climbing, rigging, traffic control, or rescue caused trouble, read the ISA Safe Work Practices exam questions guide. If target occupancy, defects, consequences, or mitigation caused trouble, review the tree risk assessment exam guide. If the scenario involves cuts, branch attachments, or pruning objectives, use the ISA pruning exam study guide.

FAQ
Are these official ISA Safe Work Practices questions?
No. They are original study questions from Arborist Practice. They are not real ISA exam questions, not official ISA practice material, and not endorsed by ISA.
Is Safe Work Practices a separate ISA Certified Arborist exam domain?
Yes. ISA lists Safe Work Practices as one of the Certified Arborist exam domains. Check ISA's current exam outline for the official wording and weighting before test day.
What safety topics should I know for the exam?
Know PPE, job briefings, work-zone setup, public exclusion, electrical hazards, climbing-system inspection, aerial lift setup, chainsaw control, rigging forces, traffic control, communication, emergency response, and rescue planning.
Are Safe Work Practices questions only about PPE?
No. PPE matters, but many safety questions are about controlling exposure before work starts: utilities, pedestrians, drop zones, damaged gear, unstable equipment, unclear communication, traffic, weather, and rescue planning.
Should I answer based on how my crew usually works?
Answer based on the safest defensible practice described in the question. The exam does not reward shortcuts just because they are common in the field. If the site is uncontrolled, equipment is suspect, communication is missing, or utilities are involved, control the hazard before continuing.
