13. When calculating clearance below, why must the shock absorber be included?

    1. It shortens the lanyard by pulling the worker back upward
    2. It can extend up to about 1.2 m as it absorbs the fall
    3. It weighs enough to change the worker's fall path
    4. It has no effect on how far the worker drops

14. Why is information and training on the site-specific rescue plan important?

    1. So workers know their role and can act fast if someone falls
    2. So workers can skip the approved working at heights program
    3. So the employer does not need any rescue equipment on site
    4. So the plan can be kept secret from the supervisors

15. What must the design of a horizontal lifeline system state?

    1. The price the constructor paid for the system's parts
    2. The colour of the rope and the brand of the anchors, nothing more
    3. The names of the workers who used it on the last project
    4. How many workers can safely be attached, among other details

16. How should a worker get tools up to a work area at height?

    1. Carry them in one hand while climbing up
    2. Use a hoist, hand line, bucket or tool belt
    3. Hold them in the mouth while climbing
    4. Throw them up to a co-worker who is waiting above

17. How long is approved working at heights training valid?

    1. Three years from successful completion
    2. For the worker's whole career

    1. Only above 6 m
    2. At any height
    3. Only below 1 m
    4. Only above 3 m

19. There is not enough clearance below for a shock absorber to deploy fully. What does Ontario's regulation say?

    1. Tie a knot in the lanyard to shorten the shock absorber
    2. Do not use a shock absorber that could make the worker hit below
    3. Use two shock absorbers joined together for extra protection below
    4. Ignore the clearance, since shock absorbers are always required

    4. At least 22 kilonewtons

26. An unsecured extension ladder is 8 m long. How far out should its base be from the point below its top?
