2022 Edition of NFPA 1033

Topics in the updated edition of NFPA 1033, Standard for Professional Qualifications for Fire Investigator, cover the full range of investigation issues encountered on the job, including the following:

• Scene examination
• Documenting the scene
• Evidence collection and preservation
• Interviewing
• Post-incident investigation
• Presentation of findings

Quality investigations start with qualified investigators.

Personnel need to be prepared with the most up-to-date knowledge when facing fire risks, arson, and other hazards in both the private and public sectors. Updates were made to align the 2022 edition of NFPA 1033, Standard for Professional Qualifications for Fire Investigator, more closely with NFPA 921, Guide for Fire and Explosion Investigations, because it is common practice for fire investigators to use both standards. Requirements were also updated and simplified for end users’ understanding and ease of use.

The actions and conclusions of fire investigators can have serious consequences from legal and economic standpoints, so it is essential that they be fully qualified to evaluate the situation and circumstances so they can conduct complete, accurate investigations.

2021 Edition of NFPA 921

The 2021 edition marks some of the most substantial changes since the original publication of the document.

The Guide for Fire and Explosion Investigations offers the most complete and relevant industry information and practices. The publication features full-color images that convey core concepts and examples to provide you with deeper insight into fundamental investigation methodologies.

Notable changes in the 2021 edition include:

• Relocation of fire pattern text found throughout NFPA 921 into Chapter 6
• Restructured and rewritten Chapter 6, including the combination of fire patterns and arc-mapping as a single process of origin determination to account for the reclassification of arc mapping as a form of fire pattern analysis
• Deletion of Chapter 20, Classification of Fire Cause, and addition to Chapter 19, Fire Cause Determination, directing investigators to other standards should they need to classify the fire cause
• Revision and addition of text covering ignitable liquid detection canines (IGL canines) including training and certification
• Revised Chapter 14, Sources of Information, and substantial rewrite in relation to non-scene data
