In this scenario, the injuries sustained by Engine 2’s crew were due to radiant heat from the adjacent room and the absorptivity of the firefighters Nomex hoods. In a fire, there are two major sources of radiant heat, the flames of the fire and the hot upper layer of gases caused by the flames (Gann, 2015). Due to the firefighters staying in the kitchen and their proximity to the fire with no water to protect themselves, the personal protective equipment (PPE) absorbed much of the thermal radiation that was being produced by the adjacent room. In a fire, the firefighter’s only source of thermal protection is their PPE (Jin et al., 2018). Under normal circumstances the firefighter’s turnout gear is thermally thick, meaning it is well insulated. However, if the firefighter remains inside too long or the fire gets too hot, then the turnout gear becomes thermally thin, which can lead to injuries (Gann, 2015). The apartment reached a temperature of approximately 1832 (CSU Study Guide, n.d.). At that temperature, the firefighter’s turnout gear would have failed in a matter of seconds as temperatures that exceed 572 , only allow for 15 – 30 seconds of protection in turnout gear. With the knowledge and a basic understanding of the absorptivity of turnout gear and how heat is transferred, the firefighters on Engine 2 could have avoided the injuries that they sustained by simply increasing the distance between them and the fire. Conclusion The basic knowledge on the flow of fluids through the length and diameter of hose is an important part of every fire ground operation. Without water we cannot put the fire out, and it is imperative to understand basics fire ground hydraulics. Also, recognizing how heat is transferred and the major role it plays in the decision-making process during a structure fire is also important. Lastly, knowing and becoming familiar with the tolerances of PPE can help firefighters understand the limits of what their gear can do. Unit III Essay When pressure was restored in the attack hose that Engine 2 was using, they began to attack the fire to no avail. The conditions in the apartment continued to degrade, forcing them to advance in different directions to another room within the apartment. At the same time, Engine 5 was advancing a second attack hose to apartment 2-C. As Engine 5 opened the door to the apartment, they observed a decaying fire ignite almost immediately. In this scenario, Engine 2 observed a condition known as flashover, whereas, Engine 5 observed a condition known as a
FINAL PROJECT 9 backdraft or smoke explosion. Even though these conditions are similar in that they are both extremely dangerous, they differ in how they are developed and what their outcomes are. Flashover From this scenario, Engine 2 was in the kitchen when the sliding glass door broke, allowing the fire in the adjacent room to become well ventilated and to receive all the oxygen it needed to create a flashover. The flashover that Engine 2 observed happened when the thermal
