Near water
Near other electrical equipment
You discover the electrical cord for a drill has been damaged and some of the cord’s insulation is missing. You should?
Wrap tape around the damaged spot to prevent electrical shocks.
Check to see if the drill still works.
Tag the drill out of service and notify the department responsible for equipment maintenance.
Make sure that the cord does not come in contact with the floor.
The safest ladder to use around electricity is:
Wood
Fiberglass
Aluminum
Step stool
The earth, water, concrete and the human body are all conductors of electricity.
True
False
The extent of an electrical shock on the body depend upon all of the following EXCEPT:
Current
Path
Duration
Body weight
Injuries from electricity can include which of the following?
Electric shock that may or may not result in electrocution but can result in cellular damage
Falls
Burns
All of the above
Open knock-outs on outlet boxes:
Must be reported and repaired as soon as possible.
A.Are permitted by OSHA.
Are common because replacing knock outs is expensive.
Pose no hazard as the electrical wiring has been rerouted.
Which of the following is acceptable by OSHA standards?
An unqualified employee flipping tripped breakers in a breaker box
Plugging an extension cord into a second extension cord
Removing a ground pin if needed to plug into a two prong outlet
A qualified person repairing an extension cord
Flexible cords can be used in the workplace:
as a substitute for permanent wiring
If the cords are run behind walls to reduce the chance of abrasion and damage
If heavy or extra heavy duty cords are needed for temporary purposes
If any obvious splices are repaired with electrical tape

True
False
Electrical current passes through body only when there is a potential difference:
True
False
High voltage shocks cause electrical burns
True
False
Electrical burn injuries are caused by electrical fires from a short circuit.
True
False
The severity of the injury caused by the electric shock:
Is independent of the magnitude of the electrical current passing into the body.
Depends on the voltage magnitude.
Depends only on the resistance of the skin surface.
Depends on the amount of current and length of time the current flows through the body.
A severe shock can cause much more damage to the body than is visible.
True
False

True
False
An electrically safe working condition:
Is required by OSHA for work on energized circuits.
Must be established before an unqualified persons can work on electrical equipment which is energized.
Can be established by locking out the power source.
