The issues were grouped under the six functional areas identified in NFPAS document 1033, the Professional Qualifications for Fire Investigators. These functional areas are scene examination, documenting the scene, evidence collection and preservation, interview and interrogation, post-incident investigation, and presentations. Twelve of the ethical issues related to fire scene examinations; interviewing received the second most frequent number of responses. Nine identical issues are identified for evidence collection, post-incident investigation, and presentations. Seven ethical issues applied to all six functional areas: ensuring truth in opinions, data, and recommendations; maintaining appropriate confidentiality; managing personal biases; avoiding manipulation of findings; working within personal capabilities; saying no to inappropriate requests; and managing time toward the interest of truth. The International Association of Arson Investigators should use these findings in its Training and Education and Ethics Committees. Table and 9 references
