Working at Heights: Anchor points and fixed supports

All 16 questions in this test

Every question and its answer choices. The correct answers and explanations appear when you take the test above.

1. Why should a worker avoid tying off to an anchor far off to one side?

   1. The lanyard would become much too short
   2. The harness would come undone
   3. A fall would swing them into an obstruction
   4. The anchor would get too hot

2. What static force must a temporary fixed support for a fall arrest system withstand (without a shock absorber)?

   1. At least 1 kilonewton
   2. At least 0.5 kilonewtons
   3. At least 8 kilonewtons
   4. At least 2 kilonewtons

3. Must a fall arrest system's fixed support be independent?

   1. Yes; it must be an independent fixed support
   2. Only on the night shift
   3. No; any shared point is perfectly fine
   4. Only for the first worker on it

4. If a shock absorber is used in the fall arrest system, what is the minimum static capacity of a temporary fixed support?

   1. 2 kilonewtons
   2. 6 kilonewtons
   3. 22 kilonewtons
   4. 12 kilonewtons

5. Which feature must a fixed support not have?

   1. A clear marking showing its rated capacity
   2. Sharp edges that could cut or chafe the connection
   3. Enough strength to hold all the forces of a fall
   4. A smooth, rounded surface where the sling wraps around

6. What is an anchor point in a fall protection system?

   1. The heaviest tool in the worker's tool belt
   2. The spot where a falling worker lands
   3. The lowest rung of a portable ladder
   4. The secure point the system is connected to

7. When must a permanent anchor system be used as the fixed support?

   1. Whenever the worker prefers it to any temporary anchor on site
   2. When installed to the Building Code and safe and practical to use
   3. Only on buildings that are more than 20 storeys tall
   4. Never; temporary anchors are always required instead

8. Which is an acceptable type of anchor according to WorkSafeBC's booklet?

   1. A load-rated sling around a substantial structural member
   2. A stack of loose lumber piled near the edge of the roof
   3. A light fixture hanging from the ceiling below the work
   4. A plastic plumbing vent sticking up through the roof surface

9. Which list names the three basic types of anchor systems taught in working at heights training?

   1. Designed fixed supports, temporary supports, verified structural features
   2. Ropes, chains and cables of any size found in the gang box
   3. Pipes, vents and railings that happen to be close to the work
   4. Ladders, scaffolds and elevating work platforms available on the site

10. What static force must a temporary support for a fall restricting system withstand, unless used to the maker's written instructions?

    1. At least 30 kilonewtons
    2. At least 1 kilonewton
    3. At least 6 kilonewtons
    4. At least 2 kilonewtons

11. Besides the static force values, how else may a temporary fixed support's capacity be shown?

    1. By its colour matching the harness
    2. By dynamic testing to good engineering practice
    3. By asking the worker if it feels strong enough
    4. By its age and how long it has been there

12. What should guide the installation of a new anchor point?

    1. The manufacturer's recommendations and, if needed, an engineer
    2. The fastest way to attach it so work can begin right away
    3. Whatever tools happen to be in the truck that morning
    4. The worker's guess about what will probably hold their weight

13. A worker arrives at a new site and is told to use an anchor they have not seen before. What should they do?

    1. Test it by jumping on it while tied off
    2. Ask for information about the anchor before using it
    3. Choose a nearby pipe instead without asking
    4. Use it without question, since all anchors are the same

14. What static force must a temporary fixed support for a travel restraint system withstand?

    1. At least 2 kilonewtons
    2. At least 8 kilonewtons
    3. At least 50 kilonewtons
    4. At least 22 kilonewtons

15. Before using an existing structural feature as an anchor, what is needed?

    1. Nothing if it looks strong
    2. Verification by an engineer or competent person
    3. A quick visual check by anyone on the crew
    4. A photo sent to the supplier for approval

16. What can result from using an inappropriate item as an anchor point?

    1. The lanyard becomes shorter and safer
    2. The anchor can fail and the worker can fall
    3. Nothing; any solid-looking item will work fine
    4. The harness will automatically tighten
