15.What is Step Potential? Circle the correct definition:
A.Step Potential is the voltage value between the span of one step. Each foot is referenced to a different potential or voltage. This deadly difference of voltage is called a Step Potential Hazard.

18.Fall protection is only required when climbing up the structure, but not during the climb down. True False
19.Red flags are installed on the live line side of a double circuit structure or on similar lines next to the one being painted to prevent workers inadvertently going towards live lines. True False
20.An Electric arc can reach temperatures four times as high as that of the sun’s surface.
True False
21.A current flow as low as 75 ma through a person’s heart will cause heart fibrillation. True False
22.OSHA requires that live parts to which an employee may be exposed shall be de-energized before the employee works on or near them. (Near = within the MAD) unless de-energizing introduces additional or increased hazards, or it is infeasible. True False
23.OSHA only requires one person on the jobsite to be trained in CPR & First aid
