Sample Working at Heights questions

Tap a question to see the answer. The full interactive test is at the top of the page.
  1. 1What must be true of a vertical lifeline's lower end?
    • A. It reaches the ground or has a positive stop
    • B. It is tied around the worker's own waist
    • C. It is left hanging loose midair
    • D. It is cut short to save weight

    A vertical lifeline must extend to the ground or have a positive stop that prevents the rope grab from running off the end.

  2. 2What is the difference between an automatic and a manual rope grab?
    • A. An automatic one is for ladders; a manual one is for horizontal lines
    • B. An automatic one moves with you and locks; a manual one stays put
    • C. An automatic one needs batteries; a manual one runs on air pressure
    • D. There is no difference; the names are interchangeable

    An automatic (mobile) rope grab travels with the worker and locks in a fall; a manual rope grab stays locked and must be moved by hand, so it suits restraint.

  3. 3When using an automatic rope grab, what lanyard length does WorkSafeBC recommend?
    • A. Any length at all
    • B. 6 metres (20 ft)
    • C. 0.6 metres (2 ft)
    • D. 3 metres (10 ft)

    WorkSafeBC recommends limiting the lanyard to 0.6 m (2 ft) when using an automatic rope grab, which reduces the fall distance before it locks.

  4. 4What is the role of a safe work plan for work at heights?
    • A. Identify fall hazards and share them with workers and supervisors
    • B. Record the names of the workers who refused to climb a ladder
    • C. Set the hourly wage for each worker who works on a roof
    • D. List the brands of harness the company prefers to buy

    The standard says safe work plans identify potential fall hazards, and their importance lies in communicating them to workers and supervisors.

  5. 5Before any worker uses a fall arrest system or a safety net on a project, what must the employer develop?
    • A. A list of nearby hospitals posted only at the company's head office
    • B. Written procedures to rescue the worker after a fall is arrested
    • C. A verbal promise that someone will call for help if needed
    • D. A plan to finish the job before anyone has a chance to fall

    Section 26.1(4) requires the employer to develop written procedures for rescuing a worker after the fall has been arrested, before any use of fall arrest or safety nets.

  6. 6Which feature must a fixed support not have?
    • A. A clear marking showing its rated capacity
    • B. Sharp edges that could cut or chafe the connection
    • C. Enough strength to hold all the forces of a fall
    • D. A smooth, rounded surface where the sling wraps around

    Section 26.7(4) says a fixed support must not have sharp edges that could cut, chafe or abrade the connection between it and another component.

  7. 7If a shock absorber is used in the fall arrest system, what is the minimum static capacity of a temporary fixed support?
    • A. 2 kilonewtons
    • B. 6 kilonewtons
    • C. 22 kilonewtons
    • D. 12 kilonewtons

    Section 26.7(2) lowers the requirement to at least 6 kN when a shock absorber is also used in the fall arrest system.

  8. 8What must an employer's instructions on fall protection include?
    • A. How to choose a lanyard colour that matches the company
    • B. How to rescue a worker who has fallen and cannot self-rescue
    • C. How to file a lawsuit after a worker is hurt in a fall
    • D. How to repaint the harnesses once each year

    WorkSafeBC lists instructions on how to rescue a worker who has fallen and cannot initiate self-rescue among the employer's required instructions.

  9. 9What does three-point contact on a ladder mean?
    • A. Two hands and a foot, or two feet and a hand, on the ladder
    • B. Three workers holding the ladder steady at all times below
    • C. Three rungs between each step you take going up or down
    • D. Three ties fastening the ladder to the structure

    CCOHS says maintain three-point contact by keeping two hands and one foot, or two feet and one hand, on the ladder at all times.

  10. 10When moving between anchor points, what must a worker do?
    • A. Stay tied off at all times, for example with a second lanyard
    • B. Unhook completely and walk quickly to the next anchor
    • C. Ask a co-worker to hold the lanyard in their hands
    • D. Hold onto the guardrail instead of using any lanyard at all

    Learners must demonstrate methods to maintain tie-off at all times when changing anchor points, considering body position, the fall hazard and direction of travel.

About the test

About the Ontario Working at Heights Training — Written Test

In Ontario, a worker on a construction project who may use a travel restraint system, fall restricting system, fall arrest system, safety net, work belt or safety belt must complete a working at heights training program approved by the Chief Prevention Officer and delivered by an approved provider. The training is valid for three years. Employers keep a record of it and must also give site-specific training on the fall protection equipment their workers use.

An approved program has two modules. The Basic Theory module, at least three hours, covers rights and responsibilities, fall hazards, the hierarchy of controls, warning methods and barriers, guardrails and safety nets, and ladders. The Practical module, at least three and a half hours, covers fall protection systems, harnesses and lanyards, anchors, work access equipment and rescue planning, with hands-on equipment. There is a written test, and learners need at least 75 per cent; the evaluator then reviews any wrong answers with them. The standard does not publish the number of questions.

Our twelve topics follow the standard's learning outcomes and the construction regulation: who needs training, roles and rights, recognizing fall hazards, the order of protection, guardrails and openings, ladders, travel restraint and fall arrest systems, harnesses and lanyards, lifelines, anchors, fall distance and clearance, and rescue planning. Key numbers include the 3 metre trigger, guardrails 0.9 to 1.1 metres high with an 89 millimetre toe board, a 0.6 metre free fall for fall restricting systems, an 8 kilonewton limit on arrest force and 8 kilonewton temporary anchors.

Where a rule comes from British Columbia's WorkSafeBC booklet rather than Ontario law, the explanation says so. Ontario workers must always follow O. Reg. 213/91, the manufacturer's instructions and their employer's site-specific procedures.

This site is independent. It is not affiliated with the Ministry of Labour, Immigration, Training and Skills Development, the Chief Prevention Officer or any approved training provider, and our practice tests do not count as working at heights training. Only an approved program does. Use these questions to learn the rules well enough that the real test, and the real job, feel familiar.

Study plan

How to prepare

  1. 1Check the date on your proof of training: it is valid for three years, and the refresher is the Practical module.
  2. 2Learn when Ontario's fall protection rules apply: more than 3 metres, more than 1.2 metres on a wheelbarrow path, or any height over machinery, water, hazardous substances or openings.
  3. 3Memorize the order of protection: guardrail first, then travel restraint, fall restricting, fall arrest and safety net.
  4. 4Know the guardrail numbers: 0.9 to 1.1 metres high, a midrail halfway, an 89 millimetre toe board and no more than 300 millimetres from the edge.
  5. 5Learn the system numbers: 0.6 metre free fall for fall restricting, 8 kilonewton maximum arrest force, and 8, 6 and 2 kilonewton temporary anchors.
  6. 6Practise inspecting a harness and lanyard in your head: webbing, stitching, buckles, D-rings, labels and the shock absorber pack.
  7. 7Take one topic test at a time and read every explanation for questions you miss. Each one names the section behind the answer.
  8. 8When you score 34 or more out of 40 on two different mock exams, you have a comfortable margin over the 75 per cent pass mark.

FAQ

Working at Heights test questions people ask

What is the passing mark for the working at heights test in Ontario?

The Chief Prevention Officer's program standard requires at least 75 per cent on the written test. After you pass, the evaluator must review your incorrect answers with you. Our mock exams use the same 75 per cent: 30 out of 40.

How many questions are on the working at heights test?

The program standard does not set a number of questions; each approved provider writes its own written test, either at the end of each module or the whole program. Our mock exams use 40 questions as a practice standard.

Are these the real working at heights test answers for Ontario?

No. Providers do not publish their tests, and sharing them would be cheating. Every question here is original and written from Ontario's construction regulation and the official program standard, so learning these rules prepares you for any version of the test.

How long is working at heights training valid in Ontario?

Three years from the date you successfully complete the program. To renew it, you complete the Practical module again as refresher training, which gives you another three years.

How long is the working at heights course?

In a classroom, at least 3 hours for Basic Theory and 3.5 hours for the Practical module. Basic Theory can be taken by eLearning or live distance learning with an instructor; the Practical module must be in person.

Do I need working at heights training to use a ladder?

The O. Reg. 297/13 requirement is triggered when a construction worker may use a fall protection system such as a harness, travel restraint, safety net or safety belt. Ladder safety is part of the Basic Theory module, and your employer must train you on the equipment you use.

Is my training still valid if I change employers?

Yes, if it is within three years and was given by a provider approved at the time. Your new employer must still give you site-specific training on their fall protection equipment and procedures.

Is the working at heights practice test available in French?

Yes. Every question is available in Canadian French with the same answers and explanations, using the official French terms of Ontario's regulations.
