10. Circle the correct answer. What is an arc flash?
a. A phenomenon where electric current leaves the intended path and travels through the air from one conductor to another, or ground
b. Electrical energy large enough to cause damage to humans while performing maintenance of rail lines
c. When humans are exposed to a lethal amount of electrical energy during lockout/tagout procedures
d. When electricity flows through the body through the hands and exits to ground through the feet
11. True or false. Contact with a source of electrical energy hot enough can cause only external burns.
12. True or false. If you see a victim of an arc flash, you should touch them to make sure they are conscious.
13. True or false. You should never tell a victim of arc flash to move, or move the victim yourself as neck or spinal injuries may have occurred.
14. True or false. The first thing to do if someone is lying near an electrical circuit and appears unconscious is to shut off the power via the appropriate disconnect switch or circuit breaker.
15. Describe what a zero energy state is:
16. True or false. Lockout/tagout procedure has individuals with shared padlock or combination locks and do not need to fill out paperwork describing the nature and duration of the work they are performing.
17. Circle the correct answer. Which of the following items does PPE not protect?
a. Injury by blunt impacts b. Electrical hazards
c. Heat, chemicals and infection

a. USDOT b. USDOL c. NFPA d. OSHA e. USDA f. IEEE
21. True or false. The National Electric Code (also known as NEC or NFPA 70) is a standardized set of code requirements and regulations for fire prevention device installation and reducing hazards mandated at state and local levels.
22. What is due process?

29. What are some issues HI-pot testing help maintainers find?
30. True or false. A Digital Low Resistance Ohmmeter (DLRO) can identify lack of resistance in electric circuits or interrupted flow and prevent long-term damage and excess energy waste.
