,QUESTIONS
Question 1
For a focused assessment of System Hazards, which set keeps all three considerations
within the appropriate area? The assessment must address “dry chemical” together
with two other relevant considerations.
A. dry chemical; asphyxiation; , and foam concentrate quantities satisfy original engineering
and design requirements
B. dry chemical; asphyxiation; toxic breakdown products
C. dry chemical; Detector Testing; toxic breakdown products
D. proper lockout procedures; asphyxiation; toxic breakdown products
Correct Answer: B
Full Explanation:
For System Hazards, the relevant details are: System Hazards: Recognizing specific safety dangers
associated with gaseous, foam, dry chemical, and aerosol suppression agents (e.g., asphyxiation, toxic
breakdown products, high-pressure discharge). For System Hazards, the relevant details are: System
Hazards: Recognizing specific safety dangers associated with gaseous, foam, dry chemical, and
aerosol suppression agents (e.g., asphyxiation, toxic breakdown products, high-pressure discharge).
For System Hazards, the relevant details are: System Hazards: Recognizing specific safety dangers
associated with gaseous, foam, dry chemical, and aerosol suppression agents (e.g., asphyxiation, toxic
breakdown products, high-pressure discharge). Each alternative replaces one relevant consideration
with a concern from another area.
Question 2
For a focused assessment of Physical Inspections, which set keeps all three
considerations within the appropriate area? The assessment must address “conditions
limiting proper operation” together with two other relevant considerations.
A. wear; conditions limiting proper operation; agent containers
B. alarm; conditions limiting proper operation; agent containers
C. wear; conditions limiting proper operation; Conducting smoke detector sensitivity tests and
testing thermal/flame detectors
D. wear; synchronization; agent containers
Correct Answer: A
Full Explanation:
For Physical Inspections, the relevant details are: Physical Inspections: Visually inspecting system
components, agent containers, piping, and wiring for damage, wear, or conditions limiting proper
operation. For Physical Inspections, the relevant details are: Physical Inspections: Visually inspecting
system components, agent containers, piping, and wiring for damage, wear, or conditions limiting
proper operation. For Physical Inspections, the relevant details are: Physical Inspections: Visually
inspecting system components, agent containers, piping, and wiring for damage, wear, or conditions
limiting proper operation. Each alternative replaces one relevant consideration with a concern from
another area.

Question 3
A work assignment is specifically concerned with Physical Inspections. Which
consideration best addresses that assignment?
A. Visually inspecting system components, agent containers, piping, and wiring for damage,
wear, or conditions limiting proper operation
B. Verifying that clean agent, CO
C. synchronization
D. control system circuits
Correct Answer: A
Full Explanation:
For Physical Inspections, the relevant details are: Physical Inspections: Visually inspecting system
components, agent containers, piping, and wiring for damage, wear, or conditions limiting proper
operation. For Notification Appliances, the relevant details are: Notification Appliances: Testing
notification devices for adequate visibility, synchronization, and audibility. These areas address
different questions, so their considerations should not be treated as interchangeable.
Question 4
A review centers on “protection requirements for fire protection and releasing
circuits”. Which area most directly addresses this concern?
A. Component Placement
B. Piping and Restraints
C. Circuit Protection
D. Compatibility
Correct Answer: C
Full Explanation:
For Circuit Protection, the relevant details are: Circuit Protection: Determining proper wire types,
sizing, and protection requirements for fire protection and releasing circuits. For Compatibility, the
relevant details are: Compatibility: Ensuring all mechanical and electrical equipment is fully
compatible with the specified extinguishing agent. The distinction is the subject being evaluated, not
merely the fact that both activities occur in the same professional setting.

Question 5
A review centers on “weather stripping”. Which area most directly addresses this
concern?
A. Optical Adjustments
B. Addressing Devices
C. Piping and Mechanical Components
D. Room Integrity Hardware
Correct Answer: D
Full Explanation:
For Room Integrity Hardware, the relevant details are: Room Integrity Hardware: Confirming the
physical installation of enclosure sealing components, door sweeps, closers, weather stripping, and
firestopping. For Optical Adjustments, the relevant details are: Optical Adjustments: Setting flame
detector viewing angles and sensitivity thresholds according to site conditions and system plans. The
distinction is the subject being evaluated, not merely the fact that both activities occur in the same
professional setting.
Question 6
An assessment identifies “Reconditioning cylinder valves, replacing safety rupture
discs, and installing safety shipping devices” as its central concern. Which focus best
fits that assessment?
A. Recharge Procedures
B. Valve Reconditioning
C. Cylinder Requalification
D. Notification Appliances
Correct Answer: B
Full Explanation:
For Valve Reconditioning, the relevant details are: Valve Reconditioning: Reconditioning cylinder
valves, replacing safety rupture discs, and installing safety shipping devices. For Recharge Procedures,
the relevant details are: Recharge Procedures: Recharging clean agent, CO. The distinction is the
subject being evaluated, not merely the fact that both activities occur in the same professional
setting.
