Introduction
The Evidence Recovery Diver Certification Exam assesses the knowledge and skills required to perform underwater
search, recovery, and forensic preservation operations safely and effectively. The examination evaluates competency in
foundational dive theory, applied professional judgment, regulatory compliance, and ethical decision-making within
,public safety diving contexts. Questions are structured as multiple-choice items, including scenario-based prompts that
simulate real-world operational challenges. Candidates must demonstrate critical thinking and situational awareness
to identify appropriate procedures, recognize hazards, and apply correct forensic techniques. This assessment ensures
divers are prepared to support law enforcement investigations, recover evidence with integrity, and contribute to the
administration of justice while prioritizing team safety and professional standards.
SECTION ONE: QUESTIONS 1–50
Question 1
Which of the following best defines the primary operational objective of an evidence recovery diver?
A. Maximizing the quantity of items recovered regardless of evidentiary value
B. Locating, documenting, and recovering evidence while preserving its integrity for legal proceedings
C. Recovering property solely for insurance restitution purposes
D. Conducting searches independently without surface support coordination
🟢 Correct Answer: B. Locating, documenting, and recovering evidence while preserving its integrity for legal
proceedings
🔴 Explanation: Evidence recovery divers operate within a forensic framework where the evidentiary value of items
depends on proper documentation and preservation. Recovering items without maintaining chain of custody or
scene integrity renders evidence inadmissible, undermining the investigative purpose.
,Question 2
Under the OSHA 29 CFR 1910.400 Subpart T standard, public safety divers operating in an emergency response
capacity are exempt from certain commercial diving requirements only during which timeframe?
A. The first 24 hours of a submerged body
B. The first hour that a body has been submerged
C. The first 48 hours following incident notification
D. The entire duration of the recovery operation
🟢 Correct Answer: B. The first hour that a body has been submerged
🔴 Explanation: The OSHA exemption for emergency response divers applies specifically during the initial one-hour
window following submersion. Beyond this period, operations transition to commercial diving standards, requiring
full compliance with Subpart T regulations.
Question 3
A diver is conducting a search in zero-visibility water using a tethered pattern. The tender notices the diver has
stopped moving and is not responding to line signals. What is the tender's first action?
A. Immediately enter the water to retrieve the diver
B. Wait five minutes to see if the diver resumes movement
, C. Signal the diver with the emergency recall signal and prepare the standby diver
D. Pull the diver forcefully to the surface using the tether
🟢 Correct Answer: C. Signal the diver with the emergency recall signal and prepare the standby diver
🔴 Explanation: The tender's role is to maintain communication and coordinate emergency response. Signaling the
diver and preparing the standby diver follows established protocols. A tender should never enter the water, as this
leaves the primary diver without surface support.
Question 4
Which of the following is the most appropriate action when a diver locates a firearm underwater during an evidence
search?
A. Immediately pick up the firearm and swim it to the surface
B. Mark the location, photograph it in situ, and document its position before recovery
C. Disassemble the firearm underwater to render it safe
D. Leave the firearm in place and continue searching for other items
🟢 Correct Answer: B. Mark the location, photograph it in situ, and document its position before recovery
🔴 Explanation: Evidence must be documented in its original position before any disturbance. Photographing and
marking the item in situ establishes its location and condition, preserving the integrity of the scene for investigators.
