When conducting a fire investigation, should you investigate alone or in pairs?

Investigating a fire scene in pairs is considered a best practice for safety reasons. This approach allows investigators to support each other and share observations, which can lead to a more thorough examination of the scene. Working in pairs enhances communication and collaboration, making it easier to identify potential hazards, such as structural instabilities, hazardous materials, or ongoing risks at the site, especially in areas that may be unsafe.

Additionally, having a partner can provide an extra layer of safety, as one investigator can assist or call for help if the other encounters a dangerous situation or emergency. The combined skills and perspectives of two individuals typically lead to a more effective investigation, making it easier to document findings accurately and conduct interviews, as well as ensuring that the emotional and psychological demands of the job are shared.

Investigating alone may increase the risk of injury or missing vital evidence, while larger groups can become unwieldy and complicate communication. Moreover, having just a supervisor does not guarantee the added safety and collaborative benefits that come from working in pairs. Therefore, conducting fire investigations in pairs is the recognized standard for maximizing safety and efficiency.
