A. Immediately run outside
B. Stay inside, move away from windows, and seek cover under a table or desk -3
C. Stand in a doorway with your arms extended
D. Continue your experiment carefully
Answer: B
Rationale: Earthquake procedures specify staying inside, moving away from
windows/shelves/heavy objects, and seeking cover under a table, desk, or strong
doorway while protecting your head and neck. -3
4. Which of the following is NOT permitted inside ECE buildings according to
safety policies?
,A. Medical/ADA approved devices
B. E-scooters and skateboards -3
C. Wheelchairs
D. All of the above are permitted

Rationale: University policy prohibits e-scooters, skateboards, bicycles, and other
wheeled devices inside buildings (except for medical/ADA approved devices). -3
5. Appropriate laboratory attire includes:
A. Sandals and shorts
B. Halter tops
C. Closed-toe shoes and no loose clothing -3
D. Any comfortable clothing
Answer: C
Rationale: PPE requirements include eye protection, appropriate attire (no shorts, halter
tops, sandals, or open-toed shoes), and confinement of loose clothing and long hair. -3
6. If a fire is discovered in the laboratory, the first action should be:
A. Attempt to extinguish it immediately
B. Shout for assistance and activate the nearest fire alarm -3
C. Gather your personal belongings
D. Open all windows
Answer: B
Rationale: Fire response procedures begin with shouting for assistance and activating
the nearest fire alarm before attempting to extinguish small fires. -3
7. When evacuating during a fire alarm, you should:
A. Use the elevator for faster exit
B. Close doors (do not lock them) and use designated exits -3
C. Leave equipment powered on
D. Re-enter the building once the alarm stops
Answer: B
Rationale: Evacuation procedures require securing equipment, closing doors without
locking, using designated exits, avoiding elevators, and not re-entering until
authorized. -3
8. How should damaged or missing equipment be reported?
A. Verbally to a classmate
B. Via the online ECE Lab Issue Report to the instructor and Department Technician -
3
C. By writing a note and leaving it on the bench
D. No report is necessary
Answer: B
Rationale: Equipment issues must be reported to the instructor and Department
Technician via the online ECE Lab Issue Report. -3
, 9. Lab doors must remain:
A. Locked at all times
B. Fully open when the lab is occupied -3
C. Propped open with a chair
D. Closed but unlocked
Answer: B
Rationale: The door policy states lab doors must remain fully open when occupied. -3
10. When should you verify your circuit connections?
A. After power is applied
B. With the instructor before starting -3
C. Only if the circuit doesn't work
D. Never
Answer: B
Rationale: Equipment verification with the instructor before starting is required to
ensure safe and correct connections. -3
11. Capacitors can pose a hazard even after power is removed because:
A. They are heavy
B. They can hold charge for a long time and discharge rapidly -14
C. They are flammable
D. They emit radiation
Answer: B
Rationale: Safety training warns that capacitors can hold charge a long time after
power is removed and deliver that charge very rapidly. -14
12. The "One Hand Rule" is used to:
A. Test components with one hand
B. Avoid presenting your body as a ground path -14
C. Hold probes steady
D. Measure current
Answer: B
Rationale: The One Hand Rule helps avoid creating a path for current through your
body (e.g., hand to hand across the heart). -14
13. Before taking a resistance measurement with an ohmmeter, you must:
A. Zero the meter -15
B. Apply power to the circuit
C. Set the meter to voltage mode
D. Nothing special is required
Answer: A
Rationale: Ohmmeters must be zeroed before accurate resistance measurements can
be taken. -15
