Water Damage Restoration Technician (WRT) Certification Practice Test

For a room that measures 16 feet × 12 feet with water damage, how many air movers are typically required for the flooring?

1. 1

2. 4-5

3. 7-8

4. 2-3

The correct answer is: 4-5

In water damage restoration, the number of air movers necessary for effective drying is determined by room size, the type of materials affected, and the severity of the water intrusion. For a room measuring 16 feet by 12 feet, which totals 192 square feet, a standard guideline is to use one air mover for every 75 to 100 square feet. In this case, aligning with industry best practices, 4-5 air movers would provide sufficient airflow to promote efficient evaporation of moisture from the flooring material. This amount of equipment ensures that the air movers can cover the entire area, allowing for increased air circulation and evaporation rates, which are critical for reducing the chances of secondary damage like mold growth. Utilizing 2-3 air movers might not provide adequate coverage or airflow to facilitate optimal drying in this scenario, leading to prolonged moisture presence. Meanwhile, using 7-8 air movers could result in excessive air movement, which may not only be inefficient but could potentially create too much turbulence and frustration in coordinating the equipment within the space. Thus, having 4-5 air movers presents a balanced approach, maximizing drying efficiency while adhering to standard protocols.
