Question 1
What is the primary purpose of a lockout/tagout (LOTO)
procedure during elevator maintenance?
A. Increase elevator speed
B. Prevent unauthorized use of equipment during servicing
C. Reduce electrical consumption
D. Improve passenger comfort
Correct Answer: B. Prevent unauthorized use of equipment
during servicing.
Rationale: Lockout/tagout procedures isolate hazardous energy
sources to prevent accidental startup and protect mechanics
from injury.
