What the Legislation module covers

On the Alberta NCSO exam, Legislation covers the Occupational Health and Safety Act, Regulation and Code, due diligence, worker and employer obligations, the three worker rights, and enforcement. It is one of ten modules, and the exam draws across all of them — which is why candidates who are strong on site but narrow in coverage still fail.

Where candidates lose marks. Candidates lose marks here by knowing a rule exists but not knowing which instrument it lives in, or who carries the obligation.

These are real questions from the NCSO Prep bank, shown with their answers and the reasoning behind them. Every question in the app explains the rule it comes from, so you learn where a requirement lives rather than memorising a letter.

Sample question 1

What are the workers' three basic rights under Canadian OHS legislation?

Right to Know, Right to Strike, Right to Refuse
Right to Refuse, Right to Sue, Right to Compensation
Right to Work, Right to Know, Right to Participate
Right to Know, Right to Participate, Right to Refuse correct

Why

The three fundamental worker rights: RIGHT TO KNOW about hazards, RIGHT TO PARTICIPATE in safety activities, and RIGHT TO REFUSE dangerous work. These are protected by law - employers cannot retaliate for exercising them.

Sample question 2

What type of legislation PERMITS the government to legally regulate an area and assigns general obligations?

Regulations
The Act correct
Municipal bylaws
The Code

Why

The ACT is the enabling legislation. It gives government the authority to regulate and assigns high-level duties to employers, supervisors, and workers. The Code/Regulations contain the specific technical requirements.

Sample question 3

What does 'Due Diligence' mean in OHS?

Reporting all incidents to the government within 24 hours
Completing all required government-mandated training
Taking every reasonable precaution to prevent harm - proactively, before an incident correct
Having all workers sign a safety waiver

Why

Due diligence = proactive. You must demonstrate that ALL reasonable precautions were taken BEFORE the incident. Post-incident actions do not satisfy due diligence. It is both a legal obligation AND a defence against strict liability charges.

How to study this module

Answer before you read. Cover the options and try to produce the answer from memory. Recognition feels like knowledge and collapses under exam pressure.
Space your review. Come back to missed questions after a day, then three days, then a week. NCSO Prep schedules this automatically.
Check the source. When you miss one, read the explanation and note which instrument the rule sits in — Act, Regulation or Code.
Time yourself once you are consistent. The full exam allows up to 2 hours and requires 75%.
