What type of agents should be severely restricted on fabrics with latex backings?

The reason solvent-based agents should be severely restricted on fabrics with latex backings is fundamentally tied to the composition of the latex itself. Latex backings are vulnerable to degradation when exposed to certain solvents. Solvent-based agents can cause the latex to break down or leach, compromising the integrity and longevity of the fabric. The interaction between the solvent and the latex can lead to issues such as warping, discoloration, or even complete failure of the backing material.

In contrast, water-based agents are generally safer for fabrics with latex backings because they do not contain solvents that can harm the latex. Oil-based and alcohol-based agents also pose risks, but not to the same extent as solvent-based agents, which are specifically designed to dissolve certain materials and can have a much more detrimental effect on latex.

Understanding the chemical properties of the cleaning agents used in restoration work and their interaction with specific materials is crucial for ensuring the preservation and durability of fabrics treated in fire and smoke restoration processes.
