Refer to the Points to Ponder Scenario in the Unit II Lesson to respond to this discussion board. Do you think the byproducts of combustion would reach the warehouse's fire protection, detection, or suppression system to alarm or suppress the fire? Why, or why not? Please include the name of the person or question to which you are replying in the subject line. For example, "Tom's response to Susan's comment." ALSO PLEASE RESPOND TO ANOTHER STUDENTS COMMENT BELOW Frank: Looking at the scenario, there are numerous items that stand out as "red flags" to me.

First was the fact that the system was not rated for the combustible storage. That means that the system would not put out enough GPM to suppress or control the fire. There would also be a good chance that the system would be overrun by the amount of fire and heat produced and would have no effect at all but maybe slowing the fire for a few minutes before it overran the system. Secondly, The report states that the system was barely operational. It didn't say why.

I know during unit 1 there were issues with the available water coming into the building was inadequate due to the old pipes in the area. It could be a housekeeping issue or something was broken and was in the process of being fixed. Any way, there should have been a fire watch and getting this system operational should have been a top priority. Third, the power was out and there was no back up power to the building due to flooding. All of the fire suppression and alarm systems should have their own emergency backup in case of power failure.

Fourth, the detectors were only in the ceiling. That is not good for any fire that starts on the ground level or in those stacks. With that much space between the detectors and combustibles, by the time the heat reached the detectors to alarm it, the fire would be extremely large and would most likely overrun the suppression system possibly before it even activates. Since "unchecked fire" doubles in size every 2 minutes, without a lower temp detector closer to the ground, the system would not even have a chance to get this fire under control, even if it activated. In closing, I do not think that the system would have had enough time to respond or activate in this scenario.

The entire system was designed incorrectly for this building. The fire would have had way too much time to build before the system would even activate.

The scenario presented in the Points to Ponder of Unit II’s lesson raises critical concerns about the effectiveness of the warehouse’s fire protection, detection, and suppression systems. Understanding whether byproducts of combustion could reach these systems is essential in evaluating the potential fire response and suppression efficacy. Based on the scenario details and the analysis provided by Frank, it appears unlikely that the byproducts of combustion would effectively trigger or reach the fire suppression and detection systems in a timely manner to contain or suppress the fire.

Firstly, the role of the fire suppression system is vital in controlling fires, especially in warehouse environments storing combustible materials. However, in this scenario, the system was not rated for the specific combustible storage, which significantly impairs its ability to respond effectively. Fire suppression systems are typically designed with specific hazard classifications and flow rates (GPM - gallons per minute), tailored to the anticipated fuel load. Since the system lacked proper rating, it might not have delivered sufficient agent volume to suppress the fire or contain the combustion byproducts. As a result, the byproducts—such as smoke, heat, and toxic gases—may not have been adequately detected or suppressed (Peters et al., 2011).

Additionally, the state of system operation was problematic, described as “barely operational” with unknown reasons. The qualification and reliability of the fire detection and suppression systems are crucial; with compromised functionality, the system would have a diminished chance of detecting and responding effectively. Compounding this issue, the access to water was inadequate due to aging infrastructure, which is common in older warehouses. This shortage means that even a properly rated system might have failed to deliver enough extinguishing agents to control a rapidly developing fire (Gale et al., 2017).

Power failure is another critical factor. As discussed by Frank, the absence of backup power due to flooding meant that both fire alarms and suppression systems could have been rendered inoperative during the fire incident. Modern fire safety codes emphasize redundant power supplies, such as battery backups or generators, to ensure system operation during power outages (NFPA 25, 2017). Without these backups, the initial fire signs and subsequent suppression efforts could have been delayed, allowing byproducts of combustion to accumulate and increase the severity of the fire.

The location of fire detectors also critically influences their responsiveness. Frank criticizes the placement of detectors exclusively in the ceiling, which is inadequate for detecting fires originating at ground level or within the stacks. Smoldering fires or those starting in lower regions may generate combustion byproducts that remain undetected until the fire has grown significantly. This delay allows more byproducts to disperse into the warehouse environment, potentially overwhelming suppression systems before activation (Kuras et al., 2014). Especially in large spaces with high rack storage, the placement of detectors at multiple levels, including ground level, is necessary to ensure early detection and response.

In conclusion, the combination of an under-rated system, poor operational status, lack of backup power, inadequate detector placement, and potential water supply issues indicated by Frank suggests that combustion byproducts might not have reached the fire protection systems in time to prevent an extensive fire growth. The failure of early detection and suppression could result in a fire becoming uncontrolled, producing hazardous combustion byproducts that pose significant risks to personnel and property. This case underscores the importance of appropriate system design, regular maintenance, and strategic placement of detection devices to ensure effective fire safety response in warehouse environments.
