group participation requirements.
2. Identify the courses and other requirements for State Fire Training (SFT) Fire Investigator
Certification and other fire investigator certifications.
3. Demonstrate the ability to use the scientific method and NFPA standard 921 as the operating
analytical process throughout the investigation.
4. Demonstrate the ability to secure a fire scene and protect all evidence given the appropriate
tools, equipment and marking devices.
5. Demonstrate the ability to conduct an exterior survey to identify and preserve evidence,
interpret fire damage, identify hazards and determine all potential means of egress/ingress.
6. Demonstrate the ability to conduct an interior survey to identify and preserve areas of
potential evidentiary value requiring further examination, determine the value of the contents
and identify hazards to avoid injury.
7. Demonstrate the ability to analyze fire patterns to determine fire development, evaluate
methods and effects of suppression activities, recognize false patterns and identify areas
of origin.
8. Demonstrate the ability to interpret individual fire patterns and the burning characteristics of
the materials involved and the mechanisms of heat transfer that led to the forming of the
pattern.
9. Demonstrate the ability to discriminate the effects of explosions from other types of damage
and to identify an explosion and preserve it's evidence.
10. Demonstrate the ability to examine and remove fire debris to check for fire cause evidence,
identify potential ignition sources and preserve evidence without causing damage or
contamination.
11. Demonstrate the ability to reconstruct the area of origin to identify and correlate all protected
areas and fire patterns related to contents or structural remains, return items potentially critical
to cause determination and photo documentation to their pre-fire location and identify the
area of origin.
12 Demonstrate the ability to inspect the performance of building systems including, detection,
suppression, heating ventilation and air conditioning (HVAC), utilities, and building
compartmentation to determine the need for expert resources, consider and operating
system's impact on fire growth and spread in identifying origin areas, identify defeated or
failed systems and recognize the system's potential as a fire cause.
