What do fire fighters use to protect a building's contents from damage due to water and falling debris?

Salvage covers are specifically designed for protecting a building's contents during firefighting operations. These covers are made from durable, water-resistant materials and can be placed over furniture, equipment, or other valuable items to shield them from water damage that can occur from firefighting efforts. By using salvage covers, firefighters can minimize the impact of water and falling debris, which is crucial in preserving the integrity of the building and its contents.

The other choices, although they may have some protective qualities, are not specifically intended for use in the context of firefighting and protecting building contents. Fire blankets are typically used for extinguishing small fires or protecting individuals, while protective tarpaulins can be versatile but are not inherently designed for the unique challenges faced during a firefighting operation. Water shields may not be a commonly recognized term in the context of salvage operations and thus do not accurately describe the intended protective measures utilized by firefighters.
