Which of the following is NOT a reason to conduct fire spread analysis?

Conducting a fire spread analysis is key in understanding how a fire developed and moved throughout a structure. The primary goals of this analysis often include tracing the fire's origin, assessing the validity of the origin hypothesis, and identifying how the fire spread from that initial point.

When considering the purpose of fire spread analysis, assessing the effectiveness of fire extinguishers is not typically included in these objectives. Fire spread analysis focuses more on the behavior of the fire and its movement rather than evaluating how well suppression methods performed at the scene. This analysis provides insights into the dynamics of the fire, which can be essential for determining safety protocols, investigating the cause, and informing prevention strategies.

As a result, the idea of evaluating fire extinguisher effectiveness falls outside the primary objectives of fire spread analysis, making it the correct answer in this context.
