In the context of water damage restoration, what does "ACH" refer to?

Air Change Rate
Active Cleaning Hazard
Air Circulation Heat
Air Contact Height

The correct answer is: Air Change Rate

In water damage restoration, "ACH" stands for Air Change Rate, which is a crucial concept in managing indoor air quality during the restoration process. ACH measures how many times the air within a defined space is replaced in one hour. It is significant because, during water restoration, it is essential to maintain healthy air quality, especially when dealing with contaminants or mold growth that can arise from moisture. High ACH is necessary to ensure that any pollutants, such as mold spores or volatile organic compounds (VOCs), are effectively removed from the air. This is often achieved through the use of dehumidifiers and air movers, which help to circulate and refresh the air in the affected area. Understanding and applying the correct ACH helps restorers minimize the health risks associated with water damage and ensure a successful restoration process.
