Compliance & Operating Rules | 2026 Edition.
DOMAIN 1: EMPLOYEE SAFETY RESPONSIBILITIES & PERSONAL PROTECTIVE
EQUIPMENT (8 Questions)
Question 1 (Multiple Choice)
Rule 70.1 - Personal Safety Accountability
According to GCOR Rule 70.1, what are employees required to do when they encounter
unsafe conditions in the workplace?
A) Report unsafe conditions only if they directly affect the employee's immediate task
B) Correct or protect against unsafe conditions and maintain situational awareness while
working within their physical limits [CORRECT]
C) Wait for a supervisor to arrive before addressing any unsafe condition
D) Document the unsafe condition in writing but continue working normally
Rationale: GCOR Rule 70.1 establishes that employees are personally accountable for their
safety as a condition of employment. The rule explicitly requires employees to work within
their physical limits, correct or protect against unsafe conditions, and maintain situational
awareness. This reflects the fundamental safety principle that every employee is responsible
for identifying and mitigating hazards in their work environment, not merely avoiding them
personally.
Question 2 (Multiple Choice)
Rule 70.1 - Personal Safety Accountability
A conductor observes a broken handrail on a locomotive platform but is running behind
schedule. What does Rule 70.1 require?
A) Proceed with caution and report the defect at the end of the shift
B) Ignore the defect if it doesn't directly impede the current task
, 2
C) Take action to correct or protect against the unsafe condition before proceeding [CORRECT]
D) Notify the engineer only and continue with duties
Rationale: Rule 70.1 mandates that employees must correct or protect against unsafe
conditions they encounter, regardless of schedule pressure. Working within physical limits
and maintaining situational awareness includes addressing hazards immediately. The
principle of personal safety accountability requires proactive intervention, not passive
observation or delayed reporting.
Question 3 (True/False)
Rule 1.1 - Safety Importance
Rule 1.1 states that safety is the most important element of railroad operations and that
obeying rules is essential to both job safety and continued employment.
TRUE [CORRECT]
Rationale: GCOR Rule 1.1 explicitly establishes safety as the paramount element of railroad
operations. The rule clearly states that obeying rules is essential to job safety and continued
employment, making compliance a fundamental condition of railroad service. This
underscores that safety violations carry employment consequences beyond immediate
physical risk.
Question 4 (Select-All-That-Apply)
Hearing Protection Requirements
In which of the following situations is hearing protection required on Union Pacific property?
(Select all that apply)
A) Working within 150 feet of an operating locomotive [CORRECT]
B) Inside a locomotive cab with all doors and windows closed
C) Working within 10 feet of master retarders or group retarders (requires dual protection:
plugs + muffs) [CORRECT]
D) Inside an enclosed office or lunchroom area
, 3
Rationale: Union Pacific hearing protection standards require protection within a 150-foot
radius of operating locomotives. Dual protection (both earplugs and earmuffs) is mandatory
within 10 feet of master or group retarders due to extreme noise levels. Hearing protection is
NOT required inside enclosed locomotive cabs with closed doors/windows or in
office/lunchroom areas, as these are designated exceptions where noise exposure is
controlled.
Question 5 (Multiple Choice)
Hearing Protection Requirements
A yard employee is performing switching operations 8 feet from a master retarder. What level
of hearing protection is required?
A) Single hearing protection (earplugs OR earmuffs)
B) No hearing protection required in yard areas
C) Dual hearing protection (earplugs AND muffs) [CORRECT]
D) Hearing protection only required within 5 feet of retarders
Rationale: Union Pacific standards mandate dual hearing protection (both earplugs and
earmuffs) when working within 10 feet of master retarders or group retarders. The 8-foot
distance in this scenario falls within the 10-foot threshold requiring maximum auditory
protection. The dual protection requirement exists because retarders generate noise levels
that exceed the protective capacity of single hearing protection devices.
Question 6 (Multiple Choice)
Eye Protection Requirements
Eye protection is required on Union Pacific property for all on-duty employees EXCEPT when:
A) Working in direct sunlight
B) Inside enclosed vehicles, locomotive cabs, or office/lunchroom areas [CORRECT]
C) Performing paperwork duties only
D) Working during nighttime hours
