Free Alberta NCSO Practice Questions
Premium includes 1,500+ original practice questions across all ten NCSO modules. Retrieval builds durable memory and exposes the gaps you did not know you had far better than simply re-reading notes.
Flashcards vs the real NCSO exam
Untimed flashcard decks (the kind that rank for “ACSA NCSO exam prep”) help you memorize terms. The ACSA NCSO Information Booklet (February 2025) describes a timed exam with a 75% pass mark across the ten-module blueprint. NCSO Prep trains that way: timed mocks, spaced repetition, and the legislation behind each answer — not a cloned card deck.

13 free Alberta NCSO sample questions
These are dummy samples for this page, not items from the paid trainer bank. Answers sit in the HTML on purpose.
1. A WHMIS skull and crossbones pictogram on a supplier label means the product is:
- An oxidizer
- Acutely toxic
- A compressed gas
- A biohazard
Answer: B. Skull and crossbones marks acute toxicity (fatal or toxic if swallowed, inhaled, or in contact with skin).
2. In the hierarchy of controls, which control is considered most effective?
- Personal protective equipment
- Administrative controls
- Elimination
- Engineering controls
Answer: C. Eliminate the hazard first. PPE is the last line of defence.
3. On an Alberta construction site, a fall protection system is generally required when a worker can fall:
- 1.2 metres
- 1.8 metres
- 3 metres or more
- 6 metres or more
Answer: C. Alberta OHS Code Part 9 uses a general 3 m trigger, with stricter rules for some tasks.
4. A confined space is typically a space that:
- Is designed for continuous occupancy with two exits
- Is not designed for continuous occupancy and has limited entry and exit
- Is any room smaller than 10 m²
- Requires only a hard hat to enter
Answer: B. Limited means of entry/exit and not meant for ongoing occupancy are the usual markers.
5. Under Alberta OHS law, who has the right to refuse dangerous work?
- Only the joint work site health and safety committee
- Only supervisors
- Workers who reasonably believe the work is unusually dangerous
- Only the prime contractor
Answer: C. Workers may refuse work they reasonably believe is unusually dangerous to themselves or others.
6. The main purpose of a planned workplace inspection is to:
- Discipline workers after an incident
- Find hazards and incomplete controls before they cause an incident
- Replace the need for a health and safety program
- Satisfy a once-a-year paperwork check
Answer: B. Inspections are proactive: find it, document it, close out the corrective action.
7. COR stands for:
- Construction Operations Review
- Certificate of Recognition
- Code of Occupational Rules
- Contractor Onboarding Record
Answer: B. A Certificate of Recognition follows a health and safety management system audit.
8. A muster point is:
- The first-aid room
- A predetermined assembly location used in an emergency
- The supervisor’s truck
- Any open area on site
Answer: B. Everyone goes to the named assembly point so you can account for the crew.
9. After a serious workplace incident, the first priority is to:
- Post on social media
- Write the final report before anyone leaves
- Make the scene safe and provide first aid, then preserve evidence
- Interview every worker on shift before treating injuries
Answer: C. People first, then lock down the scene so the investigation still has something to work with.
10. A written health and safety policy should be endorsed by:
- The newest apprentice
- Senior management
- A supplier
- The first worker who walks in
Answer: B. The policy is the organization’s commitment. It is signed at the top.
11. The ACSA NCSO exam pass mark is:
- 50%
- 65%
- 75%
- 90%
Answer: C. The ACSA NCSO Information Booklet sets the pass mark at 75%.
12. How many questions are on the NCSO exam, and how long do you get?
- 50 questions in 1 hour
- 100 questions in up to 2 hours
- 200 questions, untimed
- 10 questions, no clock
Answer: B. 100 questions, up to 2 hours, as published by ACSA. Untimed decks are not the exam.
13. Which study method matches the real NCSO exam?
- Untimed Quizlet or a Stuvia dump PDF
- Timed sets by module
- Reading the course titles once
- Memorising leaked letters
Answer: B. The exam is timed and by module. Flipping cards will not tell you if you can hit 75% in 2 hours.
How our question bank works
Every question carries the answer and the legislative reference behind it, so you learn where the rule comes from rather than memorising a letter. Questions are tagged by module and difficulty, and every answer you give feeds two things: your per-module accuracy, and a spaced-repetition schedule.
Spaced repetition, in plain terms
When you answer something correctly, we wait longer before showing it again. When you get it wrong, it comes back soon. Over a few weeks that pushes material from short-term recall into long-term memory — which is the entire difference between cramming and knowing it under exam pressure.
Practically, that means twenty minutes a day for a month will beat two full weekends of study, and the knowledge will still be there on exam day.
Practice by module
| Module | Typical question topics |
|---|---|
| Alberta OHS legislation | The OHS Act, Regulation and Code — duties of employers, workers, supervisors and prime contractors, plus the right to refuse dangerous work. |
| Health & safety programs | The elements of a written program, policy statements, roles and responsibilities, and how a program is maintained and reviewed. |
| Hazard assessment & control | Formal and field-level hazard assessments, risk ranking, and the hierarchy of controls from elimination through PPE. |
| Workplace inspections | Planned versus informal inspections, inspection frequency, documentation, and closing out corrective actions. |
| Incident investigation | Reportable incidents, evidence preservation, root cause analysis, and corrective action tracking. |
| Auditing | Audit instruments, interviewing and documentation review, scoring, and the Certificate of Recognition (COR) process. |
| Emergency preparedness | Emergency response plans, drills, muster points, rescue planning and first aid requirements. |
| Fall protection | Fall protection plans, anchor strength, travel restraint versus fall arrest, clearance calculations and rescue. |
| Confined space | Confined space versus restricted space, entry permits, atmospheric testing, attendants and rescue provisions. |
| WHMIS / GHS | Pictograms, hazard classes, supplier and workplace labels, safety data sheets and worker education requirements. |
Difficulty levels
Every question is graded easy, moderate or hard, and you can filter to whichever you need. Early on, moderate questions build confidence fastest. Closer to exam day, drilling hard questions in your weakest two modules is the highest-value hour you can spend.
Frequently asked questions
How many practice questions do I need to do?
Coverage matters more than raw volume. Our Readiness score deliberately refuses to climb until you have seen a meaningful share of every module, precisely because candidates fail on the areas they skipped rather than the ones they drilled.
Can I practise offline?
Yes. NCSO Prep runs fully offline as a progressive web app, which matters in a truck, at camp or on night shift. Progress syncs automatically once you are back in coverage.
