Category 3 Water Cleanup in the United States

So mobilization stays on track, grossly contaminated water that can contain harmful agents. With a crew geared up, under the IICRC S500 standard, it covers sewage, water from outdoors at ground level, water that contacted contamination on its way, and lower category water that degraded over time.

With a crew geared up, category 1 is clean water from a sanitary source such as a supply line.

So mobilization stays on track, category describes what is in the water. Because we answer at any hour, class describes how hard the space will be to dry, based on how much of its total surface area is wet porous material.

With a crew geared up, by how much of the total surface area of the space, meaning floor, walls and ceiling together, is wet porous material.

With a crew geared up, yes, and this is the part most people are never told. With a crew geared up, clean water answers the line soil and grows bacteria as it stands, so it is treated as Category 2 within about a day and Category 3 beyond about two days.

For an always-ready response, it means the estimate should include sealed work area, protective gear, removal of absorbed porous materials, documented disposal and a cleaned and dry release.

So mobilization stays on track, no. With a crew geared up, the category condemns porous material that absorbed the water, not the contents of the room. For an always-ready response, non porous and semi porous items such as metal, glass, sealed plastic, solid wood and plywood casework are in most cases cleaned and kept.
