When a fire is suspected to be arson or involves fatalities, the critical task is to use scientific analysis to uncover what happened and to provide those findings to the coroner. The forensic science service gathers material from the scene, conducts laboratory tests (such as examining debris and any accelerants), analyzes evidence to establish the cause and sequence of events, and then prepares expert reports for the coroner or in court. This direct focus on generating and presenting scientific evidence for the inquiry is what the service is designed to do. The other options describe activities outside this role—training on fire safety, inspecting building codes, or managing budgets—which aren’t the primary work of forensic science in these cases.
