Assignment:
Building on the Scenario:
The firefighters in apartment 2-B continued operating the nozzle without making any headway. Conditions continued to get unbearable and the firefighters backed out into another room in 2-B. Command continued to watch the turbulent black and brownish smoke issuing from the window and reaching the eaves. Command advised Engine 2 to withdraw from the apartment and the Lieutenant convinced command they had a handle on the fire and were making an aggressive knockdown and continued to remain deep into the structure where fire was still visible overhead using the TIC (thermal imaging camera). The smoke was in layers across the ceiling, which appeared as residual smoke mixed with smoke from the fire; however, no flaming was visible to Engine 2's firefighters. This was Engine 2's Lieutenant's first fire, and he did not want anyone to say he could not handle the heat. Tower 2 reported conditions in 2-H were deteriorating with tremendous heat. Engine 5 was pushing down the hallway pulling a backup line noting the smoke appeared to be lazier and maybe lighter in color than in the stairwell. They noted heat was still high as it was radiating from the walls. Engine 5 could hear crackling in the walls as they opened the door in apartment 2-C to see oxygen starved flames come to life almost simultaneously with ignition.
Instructions
For this assignment, you will complete the third essay of the scenario-based case study. The essay should be two-page narrative focusing on arguments that support what the authors discuss, as well as other research that you conduct related to these concepts.
The questions below may help you in focusing your essay on the one or two concepts chosen.
1. What are the most common oxidizers in the scenario?
2. What are the stages of a fire seen in the scenario?
3. What occurs when sufficiently high temperature is created in two rooms where both combustible materials and oxygen are present and restricted in one apartment?
4. On what does the spread mechanism of a fire depend?
5. What occurred in Apartment 2-B, 2-C, or even 2-H?
6. What is the difference between flammability and combustibility in the scenario?
7. Describe the differences between flashover, smoke explosion, or backdraft in the scenario.
1) ADDITIONAL QUESTIONS?
a) distinguish the chemical elements that contributed to the fire,
b) describe if enthalpy was a contributing factor in fire growth,
c) define concepts and terms new to you,
