Study Notes
Introduction to NFPA 921, Chapter 5
- Chapter 5 of NFPA 921 outlines the fire investigation process.
- A structured approach is crucial for comprehensive and reliable fire reconstruction.
Fire Scene Examination
- The initial step is thorough fire scene examination.
- Document all relevant evidence, noting materials and fire patterns.
- Photographic documentation (overall site views and details) is vital for preserving evidence.
Fire Origin and Cause Determination
- Fire origin and cause are determined scientifically.
- Analyze burn patterns, ignition sources, and scene context.
- Examine temperature patterns, material damage, and fire spread for inferences.
Supporting Investigations
- Consult experts (arson, structural mechanics, etc.) and other resources
- Review documents like building plans, maintenance records, and operation procedures.
Identification of Contributing Factors
- Identify factors that contributed to or exacerbated the fire.
- Include fuel availability, ignition sources, environmental conditions, and building factors impacting fire progression.
Reconstruction of the Fire Event
- Reconstruction uses all information (primary observations and supporting investigations).
- Examine burn patterns, ignition sources, and calculate fire growth tendencies.
Documentation and Reporting
- Detailed documentation (observations, measurements, evidence locations) is imperative.
- Formal reports should detail all evidence, procedures, and conclusions.
Fire Scene Safety Precautions
- Safety is paramount for investigators and others.
- Follow safety precautions, including proper personal protective equipment (PPE).
- Prevent contamination and evidence alteration by following scene safety protocols.
