Types Of Water In A Biohazard Scenario

Water damage varies in severity, and categorizing it helps professionals like SERVPRO of Federal Way effectively address and mitigate the extent of the damage. The Institute of Inspection, Cleaning and Restoration Certification (IICRC) classifies water damage into three categories:

Category 1 water, often referred to as "clean water," originates from clean sources like broken pipes, faucets, or rainwater. This water poses minimal risk to human health if ingested or exposed to the skin. However, if left untreated, Category 1 water can degrade into Category 2.

Category 2 water, known as "gray water," contains contaminants that could cause discomfort or illness if consumed or exposed to. This includes water from washing machines, dishwashers, or sump pump failures. It may contain chemical or biological pollutants, making caution necessary during cleanup and restoration.

Category 3 water, labeled as "black water," is highly contaminated and potentially toxic. This water comes from sources like sewage backups, flooding from rivers, and stagnant water. It contains harmful microorganisms, chemicals, and debris that can pose significant health risks.

Understanding these categories is essential for professionals like SERVPRO of Federal Way, as different protocols are required for cleanup and restoration depending on the severity of water contamination. Rapid response, proper equipment, and expertise are crucial to ensure the safety and health of the affected space and its occupants.
