C. AFI 91-101
D. AFI 91-301
Rationale: AFI 91-203, Air Force Consolidated Occupational Safety Instruction, replaced the 91-series
AFOSH standards. AFI 91-207 governs traffic safety programs specifically.
2. When no technical order (TO), Air Force instruction (AFI), or operating instruction (OI) covers an
existing hazard, what process can you use to assess risks and determine adequate safeguards?
A. Job safety analysis
B. Risk management
C. Hazard elimination
D. Safety review board
Rationale: Risk management is the process used when no specific guidance exists to assess risks and
determine adequate safeguards or procedures to manage those risks.
3. Many hazards on the job can be eliminated by:
A. Wearing PPE
B. Concentrating on job task
C. Working faster
D. Ignoring distractions
Rationale: By concentrating on the job task, many hazards can be eliminated through focused
attention and awareness.
4. What takes away your ability to react quickly while operating motor vehicles?
A. Fatigue
B. Distraction
C. Speed
D. Weather
Rationale: Distraction takes away your ability to react quickly while operating motor vehicles.
5. According to AFI 91-207, USAF Traffic Safety Program, what is prohibited while operating a
government-owned vehicle?
,A. Eating

C. Texting
D. Listening to radio
Rationale: Texting is prohibited while operating a government-owned vehicle while on or off a DOD
installation.
6. What is the proper way to dismount a piece of equipment?
A. Jumping down
B. Facing the machine
C. Side dismount
D. Backing down
Rationale: The proper way to dismount is facing the machine to maintain three points of contact and
reduce fall risk.
7. Before mounting a piece of equipment, you should do a quick walk around to:
A. Check tire pressure
B. Warn others near the machine to clear away
C. Inspect fluid levels
D. Check the operator's manual
Rationale: A quick walk around before mounting warns others near the machine to clear away,
preventing accidents.
8. When operating equipment in confined or hazardous areas, how can you lower the chances of
an accident?
A. Turn on hazard lights
B. Use a spotter outside the vehicle
C. Sound horn continuously
D. Reduce speed
Rationale: Using a spotter outside the vehicle helps lower accident chances in confined or hazardous
areas.
9. Electrical power tools do NOT require grounding if the:
A. Tools are new
B. Tools are double-insulated
C. Tools have plastic handles
D. Tools are battery-powered
Rationale: Double-insulated tools do not require grounding because the insulation provides
protection against electrical shock.
10. What is produced when you have extension cords plugged into power strips?
A. Surge protection
B. Heat
, C. Voltage drop
D. Increased amperage
Rationale: Plugging extension cords into power strips produces heat, which can create a fire hazard.
11. In reference to PPE, which safety equipment items could be described as the MOST important?
A. Hard hat
B. Steel-toed boots
C. Goggles
D. Gloves
Rationale: Goggles are often described as the most important PPE because eye injuries are among
the most severe and preventable.
12. Which type of hardhat SHOULD YOU NOT wear on jobs with heavy overhead assembly work
near energized electrical lines?
A. Plastic
B. Metal
C. Fiberglass
D. Composite
Rationale: Metal hardhats should never be worn near energized electrical lines because metal
conducts electricity.
13. Which Air Force Instruction (AFI) publication governs the use of protective devices?
A. AFI 91-203
B. AFI 91-207, USAF Traffic Safety Program
C. AFI 91-101
D. AFI 91-301
Rationale: AFI 91-207, USAF Traffic Safety Program, governs the use of protective devices.
14. What is an advantage for drivers and passengers who wore seatbelts when involved in
accidents?
A. They avoid all injuries
B. They have a decrease in the severity of their injuries
C. They are exempt from liability
D. They receive faster medical response
Rationale: Seatbelt wearers have a decrease in the severity of their injuries when involved in
accidents.
15. What does the acronym "ROPS" stand for?
A. Rollover Prevention System
B. Rollover Protection System
C. Rollover Positioning System
D. Rollover Performance System
Rationale: ROPS stands for Rollover Protection System, designed to protect operators in rollover
accidents.
