The direct spraying of a charred surface to contain the odor is known as what?

The process of directly spraying a charred surface to contain the odor is best described as chemical containment. This technique involves applying specially formulated solutions that help to encapsulate and neutralize odors originating from combustion byproducts. By using chemical containment, the intent is to prevent the odor-causing particles from being released into the air, thereby reducing the overall scent and improving the environment for occupants.

The application of these chemical agents is critical in fire and smoke restoration, as it addresses not only the visible damage but also the often persistent odors that can linger long after the initial cleanup. This method is distinct from other options, which may focus on covering up or masking odors rather than effectively neutralizing them through chemical means.
