Question 10

List 3 basic electrical terms that should be understood by journeyworkers and apprentices

Answer 10

1. current flow
2. voltage
3. resistance

Question 11

1. quantity
2. path
3. time

Question 12

List 4 steps for preventing injury from a machine, tool, or work site

Answer 12

1. train workers to be aware of hazards
2. control hazards by enclosing
3. use PPE to shield against them
4. eliminate the hazard

Question 13

List 5 safe practices that should be observed when using laser equipment

1. only used by trained and qualified
2. be turned off when not in use
3. don’t aim it at anyone
4. don’t operate in rain, snow, fog, dust

Question 14

What are 2 safety rules that must be observed by operators of electrically operated and gasoline driven abrasive cutting tools?

Answer 14

1. Operator must be trained, competent person
2. PPE must be worn

Question 15

What causes an electrical shock?

Answer 15

as electricity travels from it’s source and returns to that source it makes a complete circuit. If anything comes in contact with the current-carrying wires and has lower resistance than the wire, the electricity follows the path of least resistance.

Question 16

Define the term grounding

Answer 16

The electricity escapes the normal bounds of the insulated wire and follows a path of least resistance to the ground. If a grounded wire is available, the current will follow through that wire.

Question 17

What is a ground fault circuit interrupter?

Answer 17

a protective device (circuit breaker) which monitors the amount of current flowing through the hot wire of an electrical load and compares it to the amount of current coming back through the neutral wire. It will stop the flow if it exceeds

Question 18

How can current leakage be eliminated and the user of electrically operated tools be protected from this hazard?

Answer 18

inspect the tools and the grounding circuit to make sure the pathway from circuit to ground is continuous

Question 19

What is the purpose of a foot switch on a pipe machine?

Answer 19

safety feature allowing the user to use both hands and stop the machine even if they should become entangled in the rotating parts

Answer 22

false

(must be equipped)

Question 23
