1.
An Electrical Craft Helper arrives at a work location and notices an
electrical cabinet with its cover removed. The helper cannot determine
whether the conductors inside are energized. What is the safest
assumption?
A. The cabinet is de-energized because the equipment is not operating.
B. The cabinet is energized until its de-energized condition has been
properly established.
C. The cabinet is safe if the helper wears leather gloves.
D. The cabinet is safe if no sparks are visible.
Answer: B. The cabinet is energized until its de-energized condition
has been properly established.
Rationale: Treating an electrical circuit as energized until it has been
properly isolated and verified prevents a worker from relying on
assumptions such as silence, lack of movement, or the position of a
switch. OSHA guidance emphasizes that electrical hazards must be
assessed and that circuits should not be approached as safely de-
energized merely because they appear inactive.

,A supervisor tells a Craft Helper to work on equipment that is normally
energized but says, "Just be careful and don't touch anything." What
should the helper do?
A. Begin work as instructed because the supervisor accepted
responsibility.
B. Wear two pairs of gloves and proceed.
C. Stop and ensure the required electrical safety procedures and
authorization are established before proceeding.
D. Work quickly so exposure time is minimized.
Answer: C. Stop and ensure the required electrical safety
procedures and authorization are established before proceeding.
Rationale: A worker's personal caution does not replace required
electrical safety procedures. If the work involves exposure to electrical
hazards, appropriate controls, training, authorization, and PPE must
be established before work begins.
3.
What is the primary purpose of lockout/tagout procedures?
A. To identify the department responsible for equipment maintenance
B. To prevent unexpected energization, startup, or release of hazardous
energy
C. To make electrical equipment easier to locate
D. To reduce the amount of paperwork required for maintenance
Answer: B. To prevent unexpected energization, startup, or release
of hazardous energy
Rationale: Lockout/tagout is intended to control hazardous energy so
workers are protected from unexpected startup, energization, or
stored-energy release during servicing and maintenance. OSHA
2
,identifies these controls as fundamental safeguards against serious
injuries.
4.
A coworker has placed a lock and tag on an electrical disconnect and
tells you that the equipment is safe. What should you do before
beginning work?
A. Trust the coworker's statement without further action.
B. Remove the tag temporarily to inspect the disconnect.
C. Follow the applicable energy-control procedure and verify the
required isolation before work.
D. Turn the disconnect back on briefly to see whether anything happens.
Answer: C. Follow the applicable energy-control procedure and
verify the required isolation before work.
Rationale: Proper energy control includes shutdown, isolation,
securing the energy-isolating device, and verification that isolation is
effective. A worker should never defeat an energy-control measure
merely to test equipment.
5.
Which condition presents the greatest immediate concern when using a
portable electric tool?
A. The tool has minor cosmetic scratches.
B. The tool's cord has damaged insulation exposing conductors.
C. The tool is several years old but maintained properly.
D. The tool has a manufacturer label that is partially worn.
Answer: B. The tool's cord has damaged insulation exposing
conductors.
3
, Rationale: Damaged insulation can expose workers to shock, burns,
short circuits, or other electrical hazards. Damaged electrical tools and
cords should be removed from service until properly repaired or
replaced. OSHA specifically emphasizes maintaining electrical tools
and taking defective equipment out of service.
6.
Why should an Electrical Craft Helper inspect hand tools before
beginning work?
A. To determine their resale value
B. To make sure every tool has the same manufacturer
C. To identify defects that could cause injury, equipment damage, or
unsafe work
D. To determine which coworker used them last
Answer: C. To identify defects that could cause injury, equipment
damage, or unsafe work.
Rationale: Pre-use inspection helps identify cracked handles,
mushroomed heads, damaged insulation, loose components, defective
guards, and other conditions that can turn an ordinary tool into a
hazard.
7.
A worker discovers a hammer with a cracked handle. What is the
appropriate action?
A. Use it only for light work.
B. Wrap the handle with electrical tape and continue using it.
C. Give it to another worker who needs it.
D. Remove it from service and report the defect.
