1. A Public Safety Diver I certification primarily prepares a diver to
perform which type of underwater operations?
A. Recreational sightseeing dives in clear tropical waters
B. Basic emergency response and search-related diving operations as part of
a public safety team
C. Deep commercial construction diving requiring saturation equipment
D. Scientific research involving marine biology surveys
Answer: B. Basic emergency response and search-related diving operations
as part of a public safety team
Rationale: Public Safety Diver I training focuses on introducing divers to
operational procedures used in emergency response environments,
including search, recovery, and support functions while working within an
organized dive team structure.
2. Which characteristic most distinguishes public safety diving from
recreational diving?
,A. The use of underwater cameras
B. The requirement to follow a structured incident response system and
team procedures
C. The ability to dive without equipment
D. The absence of communication between divers
Answer: B. The requirement to follow a structured incident response
system and team procedures
Rationale: Public safety diving is mission-oriented and requires
coordinated operations, command structure, risk management, and
specialized procedures beyond recreational diving practices.
3. Before entering the water during a public safety dive operation, the
diver should first ensure that:
A. The dive location has no underwater hazards
B. The mission objectives, hazards, and emergency procedures have been
reviewed
C. The diver has completed a recreational sightseeing plan
D. The dive computer battery is the only equipment concern
Answer: B. The mission objectives, hazards, and emergency procedures
have been reviewed
Rationale: Proper briefing and risk assessment are essential components of
safe public safety diving because operational environments often contain
unknown hazards.
4. The primary responsibility of a Public Safety Diver I team member is
to:
,A. Act independently without supervision
B. Complete assigned tasks while maintaining personal and team safety
C. Replace the dive supervisor during all operations
D. Ignore changing environmental conditions
Answer: B. Complete assigned tasks while maintaining personal and team
safety
Rationale: Entry-level public safety divers operate as members of a
coordinated team and must follow established command procedures while
maintaining situational awareness.
5. Which organization structure is most appropriate for a public safety
dive operation?
A. Individual diver decision-making only
B. Informal buddy diving arrangement
C. Command-based team organization with assigned roles
D. Random assignment of underwater tasks
Answer: C. Command-based team organization with assigned roles
Rationale: Public safety diving relies on clearly defined roles such as diver,
tender, supervisor, and support personnel to maintain operational safety.
6. A dive tender’s primary responsibility is to:
A. Operate independently underwater
B. Support and monitor the diver from the surface
C. Replace emergency medical personnel
D. Conduct underwater investigations alone
Answer: B. Support and monitor the diver from the surface
, Rationale: The tender assists the diver by managing equipment,
monitoring conditions, and providing surface support during operations.
7. The most important reason for conducting a risk assessment before a
public safety dive is to:
A. Increase underwater visibility
B. Identify hazards and establish controls before exposure
C. Eliminate the need for communication
D. Reduce the amount of required equipment
Answer: B. Identify hazards and establish controls before exposure
Rationale: Risk assessments allow dive teams to recognize environmental,
operational, and equipment hazards and develop appropriate safety
measures.
8. Which underwater environment presents a major hazard commonly
associated with public safety diving?
A. Clear swimming pools
B. Controlled training facilities
C. Black water with limited visibility
D. Shallow recreational beaches only
Answer: C. Black water with limited visibility
Rationale: Many public safety dives involve zero-visibility or low-visibility
conditions requiring specialized techniques and strict procedures.
