In Class 2 water intrusion, what is the range of area surfaces being wet porous materials?

0% to 10%
5% to 40%
10% to 50%
30% to 70%

The correct answer is: 5% to 40%

In Class 2 water intrusion, the classification pertains to the types of materials affected and the extent of moisture exposure. This specific class indicates that there is significant saturation of porous materials, which usually includes carpets, cushions, and adjacent building structures. The characteristic of a Class 2 water intrusion event is that 5% to 40% of the area surfaces being wet involves these porous materials. This range signifies that while the less porous surfaces (like concrete or plaster) may have some moisture present, the primary concern is the greater saturation of the porous materials, which can lead to more advanced issues like mold growth if not properly addressed. Understanding this range is crucial for determining the appropriate drying methods and equipment required to restore the area effectively.
