    3. A net that catches you after a fall
    4. A harness that stops you partway through a fall

15. What is a fall restricting system?

    1. A sign that restricts entry to the roof during high winds and storms

    2. Nowhere; it can be thrown away
    3. At the engineer's home office only
    4. In the worker's personal vehicle

17. Why must the highest-ranked practicable method be used?

    1. Lower methods are banned on every construction project
    2. The ranking is only a suggestion with no legal force
