What is the main advantage of a Low Grain Refrigerant (LGR) dehumidifier over a conventional one?
Answer: It can dry air to lower humidity levels
LGR dehumidifiers can remove moisture down to lower grain levels than conventional units.
In a typical drying setup, why is creating a vortex airflow pattern recommended?
Answer: It maximizes surface evaporation in a room
A circular vortex airflow keeps air moving across all wet surfaces for efficient evaporation.
What personal protective equipment is essential when working with Category 3 water?
Answer: Gloves, respirator, and protective suit
Category 3 water exposure requires full PPE including gloves, respirators, and protective clothing.
Which factor is NOT part of the psychrometric drying process?
Answer: Soil pH
Psychrometry deals with temperature, humidity, and airflow, not soil pH.
What happens to the rate of evaporation when air temperature is increased during drying?
Answer: It generally increases
Warmer air holds more moisture and increases the evaporation rate during structural drying.
Why is monitoring moisture daily during the drying process important?
Answer: To confirm progress and adjust equipment
Daily monitoring tracks drying progress and allows equipment adjustments to reach the dry standard.
What is a primary risk of leaving a structure inadequately dried?
Answer: Mold growth and structural damage
Inadequate drying leads to mold growth, odors, and ongoing structural deterioration.
