Which of the following are considered fire effects?

The concept of fire effects encompasses the various changes and consequences resulting from a fire event. The correct option highlights the loss of material and soot deposits, which are direct consequences of a fire. When a fire occurs, it consumes materials, leading to their physical loss. This typically includes the burning of structural elements, furnishings, and other combustibles, which results in charred remnants or complete destruction of the material.

Additionally, soot deposits are residues left behind after combustion. They consist of carbon particles and other byproducts generated when organic material burns incompletely. The presence of soot serves as evidence in fire investigations, indicating areas of high heat and helping to establish the fire's origin and path.

The choice regarding smoldering and cooling describes processes related to fire dynamics but doesn't capture the broader range of physical changes resulting from a fire like material loss and soot deposition. Similarly, ignition and explosion refer to initiating events rather than the effects following a fire's occurrence. Sound generation and odor dispersion describe phenomena experienced during or as a result of a fire but do not pertain to the physical changes that are defined as fire effects in the context of fire investigation.
