The document discusses the process of examining a fire scene to determine the origin area of the fire. It describes looking for indicators on the exterior and interior of the structure, such as burn patterns, to systematically work from the least damaged to most damaged areas. Safety is the top priority when examining utilities, building systems and contents that may provide clues. Through a careful, scientific examination of all evidence, the investigator can typically identify the origin area, which is the first step towards determining the fire's cause.
This document discusses procedures for investigating fire scenes involving fatalities or injuries. It describes documenting victims and evidence, identifying bodies, and determining the cause of death. The medical examiner conducts an autopsy to examine the body and determine the cause, manner, and mechanism of death. Notifying family of a death also requires sensitivity.
The document discusses determining the cause of fires by investigating the area of origin. It describes examining evidence on the exterior and interior of structures and identifying the first material ignited to reconstruct the ignition sequence. Fires can be classified as natural, accidental, or incendiary based on whether they were caused by natural events, mistakes, or intentionally. Once the origin and cause are identified, responsibility may need to be placed on persons or faulty products.
The document discusses the importance of thoroughly documenting a fire scene through photographs, diagrams, and notes. Photographs and diagrams capture key evidence and details of the scene and fire progression. Notes are essential for compiling information from interviews and observations into a final report. Together, photographs, diagrams, and notes allow investigators to accurately recall all facts of the case.
This document discusses the importance of inspection and maintenance for fire apparatus. It outlines procedures for inspecting different components of fire trucks on a daily, weekly, and preventative maintenance basis.

This chapter discusses international practices in fire prevention by comparing statistics and approaches between the US, Canada, UK, Netherlands, Czech Republic, Russia, Japan, Germany, and New Zealand. It notes differences in fire death rates, number of fires, causes of fires, fire station locations, construction practices, education programs, and authority of fire inspectors between countries. The chapter aims to identify lessons that can be learned from other international approaches.
This chapter discusses instilling positive fire reaction in individuals. It covers how human characteristics and the environment can impact reaction to fires. Various occupancies are discussed, including homes, schools, institutions, and industries. Effective fire drills and safety manuals are recommended to condition occupants' reactions. Methods for counteracting panic in fires are also presented, such as signage, lighting, and emergency communications. Special considerations for high-rises and terrorism are addressed at the end of the chapter.
The National Fire Protection Association is the primary organization focused on fire prevention and develops fire codes and standards used by governments. Other major organizations include the International Association of Fire Chiefs and International Association of Fire Fighters. Insurance companies also promote fire prevention through ratings that influence commercial building insurance costs based on fire protection services.
This chapter discusses the organization and administration of municipal fire prevention units. It outlines that fire prevention responsibilities are primarily handled locally at the municipal level. Fire prevention bureaus can range from one-member units in small towns to larger specialized bureaus in big cities. Key functions of fire prevention units include fire safety education, inspections, code enforcement, and fire investigations. The chapter also examines relationships between fire prevention units and other local agencies.
This chapter discusses methods for enforcing fire safety codes, including plan review, control of sales and occupancy, structural control, and legal compliance procedures. Plan review involves evaluating building plans to ensure code compliance, while control of sales regulates hazardous materials. Structural control allows inspection of buildings, and occupancy control determines safe capacity. The goal of enforcement is to improve safety rather than impose penalties.
This document discusses the role of expert witnesses in court, specifically fire investigators. It summarizes key court cases like Frye, Daubert, and Kumho that established standards for expert testimony. Federal Rule 702 gives courts the role of gatekeeper to determine if expert testimony is based on sufficient facts, reliable principles, and proper application of methods. Fire investigators must understand these legal standards to be able to provide testimony in court.
The document discusses the process of developing a final report after a fire investigation and preparing to testify in court. It describes including all hypotheses, facts, and the investigator's conclusions in the final report. It also discusses preparing for court by meeting with attorneys, providing discovery documents, and maintaining a professional demeanor while testifying. The role of a public information officer to inform the public about fire investigations is also outlined.

The document provides a case study example and discusses examining the exterior and interior of vehicles to determine how and why the fire occurred. Potential heat sources and fuels are outlined, along with considerations for investigating motor homes, boats, diesel and hybrid vehicles.
The document discusses fire safety concepts from NFPA 550. It describes two main strategies for fire safety from model codes: preventing ignition and managing impact. To prevent ignition, it aims to control heat sources and fuels through regulating materials storage, smoking, and open flames. To manage impact, it focuses on limiting building size, requiring fire resistance, adequate egress, and fire protection systems.
This document describes various potential sources of ignition that could start a fire. It discusses natural sources like lightning and geological events. It also examines human-related sources such as smoking materials, matches, lighters, appliances, chimneys and more. The key is that an ignition source must be able to produce enough sustained heat to ignite the first fuel. Proper identification of the ignition source requires a scientific investigation to determine what was the competent heat source in any given fire.
This document summarizes fire protection systems, including different types of sprinkler systems, fire classes and extinguishing agents, and fire alarm and detection standards. It describes NFPA 13, 13D, and 13R sprinkler system standards and their applications based on occupancy classifications. The key aspects covered are the four classes of fire and appropriate extinguishing agents, as well as wet, dry, preaction, and deluge sprinkler systems.
This document discusses fire-resistive construction elements and ratings. It describes the difference between specification codes, which specify construction types, and performance codes, which identify required fire resistance in hours. Rated assemblies are tested according to standard time-temperature curves to determine their ability to support loads, limit heat transfer, and prevent fire spread for a specified time period. Openings in rated walls and barriers must be protected, and fire blocking and draft stopping are used to control fire spread in concealed spaces.
1. The document discusses scientific methodology and key concepts in fire behavior that are important for fire investigators to understand. It describes the scientific method and fire tetrahedron model.
2. Compartment fires are discussed, including how heat rises and forms layers, leading to potential flashover if conditions are right.
3. Different types of heat transfer - conduction, convection, and radiation - are important for investigators to understand fire spread. Understanding fuel, oxygen, and ignition factors also helps determine fire causes.
Physical evidence collection and preservation is a critical part of any investigation. First responders must secure the scene and protect any potential evidence. Investigators then identify, collect, document and properly store any evidence, following strict chain of custody procedures. Evidence is analyzed at forensic laboratories and results are communicated back to investigators. Investigators must be trained on evidence handling policy and contamination prevention to ensure the integrity of any evidence collected.
