According to the UL Video, how many gallons were used during the initial suppression period across all 21 experiments?

The correct answer is based on the specific data presented in the UL Video regarding the experiments conducted. During the initial suppression period across all 21 experiments, the total quantity of water used was noted to be 230 gallons. This figure reflects a precise measurement that was critical to understanding the effectiveness of water as a suppression agent in various scenarios.

This information is significant because it provides insight into the resource requirements for fire suppression efforts and highlights the challenges faced by fire safety professionals. The other figures presented as potential answers are not supported by the video’s data and do not represent the actual amount recorded in those experiments. Understanding these distinctions helps reinforce the importance of accurate data in fire safety research.
