1. A Public Safety Diver II is assigned to conduct a search operation in a
low-visibility river environment. Which diving practice is most
important for maintaining team safety during the operation?
A. Increasing individual search speed to reduce bottom time
B. Maintaining continuous communication, team awareness, and adherence
to the planned search pattern
C. Removing unnecessary equipment to improve swimming efficiency
D. Allowing each diver to select an independent search method underwater
Answer: B
Maintaining communication, team awareness, and following the
established search plan are essential because public safety diving requires
coordinated operations where diver safety depends on predictable
procedures and teamwork.
2. During a Public Safety Diver II operation, the dive supervisor
determines that environmental conditions have deteriorated beyond
acceptable limits. What is the appropriate action?
,A. Continue the mission because the objective is urgent
B. Allow experienced divers to decide individually whether to continue
C. Suspend or modify the operation based on risk assessment and safety
procedures
D. Increase the number of divers immediately and continue
Answer: C
A dive supervisor must prioritize diver safety by evaluating changing
hazards and stopping or modifying operations when conditions exceed
acceptable risk levels.
3. The primary purpose of a tender in a public safety diving operation is
to:
A. Replace the diver’s underwater navigation equipment
B. Provide surface support, communication, and monitoring of the diver
C. Perform independent underwater searches
D. Maintain only the dive equipment inventory
Answer: B
The tender supports the diver from the surface by managing the line,
monitoring communications when applicable, and maintaining awareness
of the diver’s condition and location.
4. A Public Safety Diver II discovers an item that may be evidence during
an underwater search. What should the diver do first?
A. Immediately remove and clean the item
B. Move the item to a more visible location
C. Protect the item’s location and follow evidence-handling procedures
D. Give the item to a bystander for safekeeping
Answer: C
,Potential evidence must be preserved and handled according to
established procedures to maintain integrity and ensure proper
documentation and chain of custody.
5. Which factor most significantly increases the hazards associated with
contaminated water diving?
A. Increased visibility
B. Reduced need for protective equipment
C. Exposure to biological, chemical, and physical contaminants
D. Lower probability of equipment damage
Answer: C
Contaminated water environments may expose divers to pathogens,
toxins, and hazardous materials, requiring specialized equipment and
procedures.
6. In a public safety diving team, the dive supervisor’s primary
responsibility is to:
A. Complete all underwater searches personally
B. Direct operations and ensure compliance with safety procedures
C. Repair all damaged equipment during the mission
D. Eliminate the need for surface support personnel
Answer: B
The dive supervisor manages the operation, evaluates risks, coordinates
personnel, and ensures that established safety protocols are followed.
7. A diver becomes entangled underwater during a search. What is the
best initial response?
A. Pull forcefully against the entanglement
B. Remove the mask and regulator immediately
C. Stop movement, control breathing, and work systematically to free the
, diver
D. Abandon all equipment and swim upward
Answer: C
Controlled responses reduce panic and air consumption while allowing the
diver to methodically resolve the entanglement problem.
8. The purpose of a pre-dive briefing in a Public Safety Diver II operation
is to:
A. Replace all written operational plans
B. Establish objectives, hazards, roles, and emergency procedures
C. Eliminate the need for underwater communication
D. Allow each diver to create personal procedures
Answer: B
A pre-dive briefing ensures all team members understand the mission plan,
responsibilities, hazards, and emergency actions before entering the
water.
9. Which search method is commonly used when a diver must
systematically cover a defined underwater area?
A. Random swimming pattern
B. Controlled search pattern such as circular, grid, or line search
C. Unplanned exploration
D. Surface-only observation
Answer: B
Structured search patterns improve coverage, reduce missed areas, and
allow teams to document where searches have been conducted.
10. A Public Safety Diver II operating at night should primarily rely
