NFPA 70E FINAL EXAM 2026 WITH 100%
ACCURATE ANSWERS
1. Why is it important to have eye wash facilities available when working
with liquid electrolytes?
Eye wash facilities are used to store liquid electrolytes safely.
Eye wash facilities are crucial for quickly rinsing the eyes in
case of exposure to hazardous substances.
Eye wash facilities are only necessary for electrical work, not
battery activities.
Eye wash facilities are a form of personal protective equipment.
2. High voltage equipment is not considered safe to touch until it's...
Locked, tagged & verified ?
Isolated, locked and tested?
De-energized, locked, & tagged, tested, and grounded?
3. Who is required to participate in the lockout/tagout process according
to safety protocols?
Anyone who could be exposed directly or indirectly to a
source of electrical energy
Only the electrical technician
Only the site supervisor
Only the safety officer
4. Describe the significance of self-locking features in tag attachments
within electrical safety protocols.
Self-locking features ensure that tag attachments remain
, securely in place, preventing accidental removal during
maintenance.
Self-locking features allow for easy removal of tags when
needed.
Self-locking features are only necessary for high-voltage
equipment.
Self-locking features are optional and do not affect safety.
5. During a battery maintenance procedure, an employee accidentally
spills liquid electrolyte on their skin. What should be the immediate
course of action regarding safety equipment?
Notify a supervisor and wait for assistance.
Apply a bandage to the area and continue working.
Use the eye wash facilities to rinse the affected area.
Use a fire extinguisher to cool the area.
6. What is a key feature that tag attachments must have according to safety
protocols?
Adjustable length
Metallic finish
Color-coded
Self-locking
7. Why is it important for only qualified persons to test and troubleshoot
circuit parts operating at 70 volts?
Apprentices can perform the tasks as long as they are
supervised.
Only qualified persons have the necessary training and
, knowledge to safely handle electrical hazards.
Any employee can learn to do it with a brief orientation.
Supervisors can oversee the process without needing
qualifications.
8. If a worksite has not established proper barricades around high-voltage
areas, what potential risks could arise for workers?
Improved efficiency in completing tasks.
Increased risk of accidental contact with electrical hazards.
Enhanced communication among workers.
Reduced need for personal protective equipment.
9. An electrically safe work condition is defined as a state in which an
electric conductor or circuit part has been? I. barricaded to prevent
access by unauthorized persons II. disconnected from energized parts
III. temporarily grounded for personnel protection, if necessary IV.
locked/tagged in accordance with established standards V. tested to
the absence of voltage
II. and IV.
I., II., IV., and V.
II., III., IV., and V.
I. only
10. Why is it important to identify all possible sources of electrical supply
before beginning electrical work?
It helps in selecting the right protective equipment.
Identifying all possible sources of electrical supply ensures
that all potential hazards are recognized and mitigated.
