,Q1. A retail store plans to store multiple classes of hazardous materials. Which
combination of storage conditions is most critical to prevent incompatible reactions?
A. Segregate by hazard class and provide separate containment
B. Store all flammable liquids together regardless of class
C. Keep oxidizers away from flammables but allow corrosives with flammables
D. Use single shelving unit with proper labeling
Correct Answer: A. Segregate by hazard class and provide separate containment
Rationale: Incompatible materials must be segregated by hazard class and physical
properties to prevent dangerous reactions. Separate containment and segregation are
fundamental to fire safety and chemical compatibility. Options B, C, and D fail to address
the need for proper segregation and containment, increasing the risk of hazardous
interactions.
Why Wrong:
B - Storing all flammables together ignores class-specific storage requirements and
can create additional hazards.
C - Allowing corrosives with flammables risks violent reactions and toxic gas release.
D - Labeling alone does not prevent incompatible materials from coming into contact.

Q2. During a routine inspection, you notice a leaking container of nitric acid in a
retail storage area. What is the FIRST action you should take?
A. Neutralize the acid with a base
B. Evacuate the area and call 911
C. Contain the spill with absorbent material
D. Ventilate the area and use a spill kit
Correct Answer: B. Evacuate the area and call 911
Rationale: The first priority in any hazardous material incident is life safety. Evacuating
the area and notifying emergency services ensures that personnel are protected and
trained responders can manage the spill. Neutralization, containment, and ventilation are
secondary actions that should only be performed by trained personnel after the scene is
secured.
Why Wrong:
A - Neutralizing acid without proper training and PPE can cause violent reactions and
hazardous fumes.
C - Containing the spill without proper PPE and training may expose the individual to
the acid.
D - Ventilation and spill kit use are important but should not precede evacuation and
notification.

Q3. Which of the following is a key requirement for the storage of compressed gas
cylinders in a retail setting?
A. Store cylinders horizontally to prevent tipping
B. Secure cylinders upright and cap them when not in use
C. Keep cylinders near heat sources to prevent freezing
D. Store full and empty cylinders together without separation
Correct Answer: B. Secure cylinders upright and cap them when not in use
Rationale: Compressed gas cylinders must be secured upright to prevent falling and have
protective caps in place when not in use. This prevents damage to the valve and potential
ruptures. Storing cylinders horizontally, near heat, or mixing full and empty cylinders
without segregation is unsafe and violates fire codes.
Why Wrong:
A - Horizontal storage can cause valve damage and is not approved for most
cylinders.
C - Heat sources increase pressure and risk of explosion.
D - Full and empty cylinders must be separated to avoid confusion and ensure proper
handling.
Reference: FDNY C36 Study Guide, Chapter 6: Compressed Gases
Q4. What is the maximum allowable quantity (MAQ) of Class I flammable liquids
that can be stored without a permit in a retail occupancy, assuming the building has
an approved automatic sprinkler system?
A. 30 gallons
B. 60 gallons
C. 120 gallons
D. 240 gallons
Correct Answer: C. 120 gallons
Rationale: Per fire codes, the MAQ for Class I flammable liquids in retail occupancies
with sprinklers is typically 120 gallons. This quantity is allowed without a permit, but
exceeding it requires additional permits and enhanced safety measures. The other options
are incorrect because they do not reflect the specific MAQ for this scenario.
Why Wrong:
A - 30 gallons is the MAQ for unsprinklered buildings, not sprinklered.
B - 60 gallons is not the standard MAQ for Class I liquids in retail with sprinklers.
D - 240 gallons exceeds the MAQ and would require a permit.
