Forensic science basics as applied to fire investigation include the study of heat and its effect on various materials. This requires understanding physical constants, such as air temperature, humidity, and temperature differentials. It is also essential to understand how fires develop and spread. Without ventilation, the fire will starve for oxygen, self-extinguishing. If there is adequate ventilation, the developing heat can escape. In general, a fire reaches a limiting temperature of about 600-1000 degrees Celsius before being fully extinguished. However, when no ventilation is present, the fire will suffocate, and killing it is equivalent to snap-freezing it.
In fire investigations, forensic engineering and material science are closely related. Forensic materials engineer investigations focus on materials, such as metals, glasses, ceramics, and polymers. A fuel pipe broken during a road traffic accident is one example of a material that can be analyzed for cracks and fractures. Forensic engineers can use this information to determine the exact cause.
Forensic science and engineering fundamentals can also be applied in the fire investigation process. Forensic engineers can examine a vehicle's design, road signs, and other aspects of roadside safety to determine if the car was correctly designed and complied with applicable codes. Using computer programs, these experts can evaluate a product's failure and recommend a remedial course of action.
Forensic engineers are often called upon as fire investigators to testify in court. Because of their expertise, they can provide expert testimony that proves a claimant's guilt or innocence. In civil fire investigation, forensic engineers can help in litigation because they are highly experienced in the field. Forensic scientists can also help in a criminal investigation.
A forensic engineer can examine a vehicle's performance by reviewing its internal components. They can also help in the courtroom determine the cause of an accident. A forensic engineer can assist in a variety of other ways. Forensic engineers can provide expert opinions on legal issues that arise from fires. A forensic expert can also be helpful in a lawsuit involving intellectual property.
A forensic engineer can be qualified in several fields. Most forensic engineers have specialized training and experience and have a degree in a specific area of expertise. Many of these professionals also have a specialized area of expertise. A forensic engineer's ability to analyze the evidence is key to a successful investigation. This specialty is increasingly needed in the fire investigation industry.
