1. Name a working condition that might be a safety concern,
and explain what you would do about it.
2. What is the overall purpose of OSHA?
3. What is SDS an abbreviation for?

1. List seven safety rules for electricity given in this
chapter. You may refer to the chapter as you list these rules, but do not copy
word for word from the chapter. Use your own words.
2. What will happen if a multimeter set in the amp position
is applied to the hot and neutral conductors of a live circuit?

Electric shock is a result of an electric current flowing
through the body. The amount of current that flows through the body is
determined by the makeup of the body (lean body tissue or fat), the entry and
exit points on the body, the degree of moisture present on the skin, and the
amount of voltage applied to the body. Using the ohmmeter function of a digital
multimeter, you will measure your body resistance between several points. Then
you will perform some simple calculations to determine the amount of voltage
required to cause a fatal current to flow through your body

1. Set your digital multimeter to the resistance range. (If
you do not have an auto-ranging digital multimeter, you will need to find the
range that will yield the best readings.)
2. Insert the black test lead into the common jack on the
digital multimeter.

1. What happened to the resistance reading from hand to hand
when you increased the pressure with which you were holding the test probes?
2. How does your resistance reading compare between your
hand-to-hand measurement and your hand-to-foot measurement?

Which ladder material should be used when you are working
near electric lines?
a. Wood
b. Aluminum
c. Fiberglass
d. Both wood and fiberglass are okay
