Water Damage Restoration Technician (WRT) Certification Practice Test

Class 1 water intrusions involve the ________ amount of water absorption.

1. Significant

2. Greatest

3. Least

4. Moderate

The correct answer is: Least

Class 1 water intrusions are characterized by a minimal amount of water absorption, which makes the corresponding option the best fit. This classification typically involves situations where only a small portion of a building's structure or materials is affected by moisture. As a result, the relative humidity and moisture content remain low, and only a limited area and volume of the materials are saturated, such as in situations affecting small, non-porous surfaces or dry materials that have absorbed minimal moisture. Understanding this distinction helps in determining the appropriate remediation strategies, as lower levels of water absorption generally lead to less extensive damage and quicker recovery processes.
