Which of the following is a precaution a worker should take to avoid on-the-job fall hazards?
a. assume that fall protection equipment and devices are safe before each use.
b. attend and participate in fall prevention training.
c. avoid using fall protection equipment that can slow down a worker’s efficiency.
d. use the same dependable ladder for every task.

Our goal is to AVOID job- related hazards. 

Let's go through the options:


a. Assume that fall protection equipment and devices are safe before each use.

This is wrong - equipment should always  be checked before use, as it wears down!

b. Attend and participate in fall prevention training.
- This is the right option. Such a  training will be a positive contribution to accident prevention, and one should pay close attention during this training. 

c. Avoid using fall protection equipment that can slow down a worker’s efficiency.
Maybe it will slow down the efficiency, but it will also decrease the risk of accidents! And in the end, accidents also slow down efficiency, so not using the fall protection is not worth it! 

d. Use the same dependable ladder for every task. This is wrong - you should use the ladder that is the most appropriate for the task
