Which search pattern is NOT typically used in fire investigations?

The sequential search pattern is not typically used in fire investigations because it does not provide a systematic approach for thoroughly examining a scene. Fire investigations require meticulous attention to detail, and investigators often rely on patterns that allow them to cover the area comprehensively and logically.

In contrast, the grid pattern is effective for thoroughly searching a larger area by overlaying a grid of lines that ensures no part of the space is overlooked. The zone search pattern divides the area into smaller, manageable sections, allowing investigators to focus on specific areas in a detailed manner. The spiral search pattern involves starting from a central point and working outward (or inward), which can be useful in smaller scenes or when the point of origin is known.

By using structured and systematic search patterns like grid, zone, and spiral, investigators can gather evidence more effectively, ensuring all potential areas of interest are examined adequately. The sequential approach lacks this systematic rigor and often leads to oversight in fire investigation contexts, making it less suitable for the complexities involved in these scenes.
