## How these questions are answered # Link to this section

 
- Water is named by category. Category 1 is clean supply water; Category 2 is significantly contaminated; Category 3 is grossly contaminated, such as sewage. The category decides what gets dried and what gets removed, and it degrades with time.

- Smoke is named by residue type. Dry smoke, wet smoke, protein residue and fuel-oil soot clean differently, and which one you have depends on what burned.

- Coverage is named by peril , and for water, by whether it came from inside the building or outside it. Flood means external water and is excluded; a burst pipe is internal water and is generally covered.
