QUESTIONS AND CORRECT ANSWERS
What is a continuity test? Correct Answer Ensures that that the
equipment grounding conductor is electrically continuous. It is
performed on all cord sets, receptacles, etc., which are not part of
the permanent wiring of the structure.
Name four continuity testers that OSHA allows? Correct Answer
Lamp ad battery
A bell and battery
An ohmmeter
A receptacle tester
What is a polarity test? Correct Answer A check on receptacles
and plugs to make sure that the equipment grounding conductor
is connected to the correct terminal. The 4 types of equipment
used for a continuity test can be used for a polarity test.
Does double insulated type equipment require a third wire?
Correct Answer N
What type of equipment could be used to test the continuity of the
case ground on a portable electrical drill? Correct Answer Volt-
ohm meter
What does the split core ammeter provide? Correct Answer A
safe way to check amperage on live circuits.
What two instruments may be used to check the capability of the
equipment ground on a branch circuit within the building or
,facility? Correct Answer The megger and the ground loop
impedance tester
What is a ground? Correct Answer An object that connects a
piece of electrical equipment to earth or some conducing body
that serves in place of earth.
What does a ground serve as? Correct Answer A ground serves
to complete the electrical circuit and prevent current from
unexpectedly flowing through an individual.
What is a GFCI? Correct Answer A fast action device that senses
a small current leakage to ground and in a fraction of a second,
shuts off the electricity and interrupts the faulty flow to ground.
Will a GFCI detect line to line faults? Correct Answer No
What does the GFCI do? Correct Answer Continually matches
the amount of current going to and from the tool along the normal
path of the circuit conductors. Whenever the amount differs from
teh amount returning by a set trip level, the GFCI interrupts the
electric power.
How fast will the GFCI interrupt the electric power? Correct
Answer 1/40th of a second.
Stainless steel welding results in fumes containing what? Correct
Answer Nickel and chromium.
The electrodes used in stainless steel welding produce what?
Correct Answer Large amounts of flourides that are released into
the air in large quantities.
According to OSHA 1926.250 brick stacks shall not be more
than________ in height? Correct Answer 7 feet
, When a loose brick stack reaches a height of _________ feet, it
shall be tapered back_______ inches in every foot of high
above________? Correct Answer 4 feet, it shall be taped back 2
inches in every foot of height above the 4 foot level.
What should be done with masonry blocks are stacked higher
than 6 feet? Correct Answer The stack shall be tapered back
one-half block per tier above the 6 foot level.
How should lumber be stacked? Correct Answer On level and
solid supported sills. Used lumber shall have all the nails
withdrawn before stacking. The stack should be stable and self
supporting.
Lumber piles should not exceed how high? Correct Answer 20
feet in heigh provided that lumber to be handled manually shall
not be stacked more than 16 feet high.
Means of egress from trench excavations such as a stairway,
ladder, ramp or other safe means of egress are required in trench
excavations that are of what depth or more? Correct Answer 4
feet or more in depth.
What is the purpose of the hoist line limit switch? Correct Answer
To prevent over travel of the load block. Often refered to as the
anti-two block device.
Respirable air under suitable pressure should be delievered to
each respirator at a volume of at least what? Correct Answer 6
CFM
Hoods on grinding and cutting operations serve a dual function.
What are the two functions? Correct Answer They protect the
worker for hazards of a bursting wheel and they provide for
