Questions and Answers
**Q1: A liquid with a flash point ABOVE 100°F is classified as:**
- **Answer:** Combustible Liquid
- **Rationale:** The distinction between flammable and combustible liquids is based on flash point.
Flammable liquids have flash points below 100°F, while combustible liquids have flash points at or above
100°F .
**Q2: If the current flowing out from an electrical panel is 12.5 amps, and it then flows through an
electrical load of 1500 watts, what is the amperage of the remaining current flow of the return
circuit?**
- **Answer:** 12.5 amps
- **Rationale:** In a series circuit, current remains constant throughout. The current flowing out must
equal the current returning, regardless of the load. The wattage (1500W) is irrelevant to the question of
amperage on the return circuit—it would be used to calculate voltage or power consumption .
, **Q3: What year was the first edition of NFPA 1033 published?**
- **Answer:** 1987
- **Rationale:** The first edition of NFPA 1033: Standard for Professional Qualifications for Fire
Investigator was published in 1987. This standard establishes the minimum job performance
requirements for fire investigators .
**Q4: A meaningful analysis of a fire requires an understanding of the fire growth, the total heat
released, and WHAT?**
- **Answer:** Heat Release Rate (HRR)
- **Rationale:** Heat Release Rate (HRR) is the rate at which energy is released by a fire. It is
fundamental to understanding fire growth dynamics and is measured in kilowatts (kW). A meaningful
fire analysis requires understanding fire growth, total heat released, and HRR .

**Q5: Which type of analysis is used to predict fire phenomena and characteristics of the
environment?**
- **Answer:** Fire Dynamics Analysis
- **Rationale:** Fire dynamics analysis applies principles of chemistry, physics, and engineering to
predict fire phenomena, including flame spread, heat release, and environmental impacts. It is essential
for origin and cause determination .
**Q6: Observable or measurable changes in or on a material as the result of a fire are called:**
- **Answer:** Fire Effects
- **Rationale:** Fire effects are physical changes to materials caused by fire exposure (e.g., charring,
melting, spalling, discoloration). They provide critical evidence for fire pattern interpretation .
