Water Damage Restoration Technician (WRT) Certification Practice Test

Which cleaning method is required for carpets affected by Category 2 water loss?

1. Dry cleaning method

2. Hot water extraction method

3. Steam cleaning

4. Vacuum cleaning

The correct answer is: Hot water extraction method

The hot water extraction method is the recommended cleaning technique for carpets affected by Category 2 water loss, which is also known as "gray water." This type of water may contain contaminants that can cause illness or discomfort, such as bacteria, viruses, or other microorganisms. The hot water extraction method involves using hot water under high pressure to deep clean the carpet fibers while simultaneously extracting the water along with any contaminants. This method not only effectively removes dirt and organic matter but also disinfects the carpet, reducing the potential for microbial growth. The heat from the hot water played a crucial role in sanitizing the fibers, which is particularly important when dealing with Category 2 water. Properly applying this method ensures that the carpet is returned to a safe and habitable condition. Other cleaning methods, such as dry cleaning or vacuum cleaning, do not provide the same level of thoroughness or the ability to sanitize properly, which are essential when dealing with water losses involving contaminants. These alternative methods may not effectively remove the potential hazards associated with gray water, making them unsuitable for this specific situation.
