Question 1

What does the IICRC S500 standard classify as Category 2 water?

Accepted Answer

Significantly contaminated water containing microorganisms

Answer

Category 2 (gray water) contains significant contamination and can cause illness if ingested or contacted, such as water from washing machines or dishwashers.

Question 2

Which psychrometric property describes the amount of moisture in the air relative to its maximum capacity at a given temperature?

Accepted Answer

Relative humidity

Answer

Relative humidity is the ratio of the actual moisture in the air to the maximum moisture the air can hold at that temperature, expressed as a percentage.

Question 3

During the drying process, what is the primary purpose of air movement in a water-damaged structure?

Accepted Answer

To move evaporated moisture away from wet surfaces

Answer

Air movers accelerate evaporation by continuously replacing moisture-saturated air at wet surfaces with drier air, enhancing the rate of drying.

Question 4

What reading on a moisture meter would typically indicate that wood flooring has reached an acceptable drying goal?

Accepted Answer

Below 16% moisture content

Answer

Wood flooring is generally considered dry and acceptable when moisture content is below 16%, though the specific goal may vary by species and pre-loss conditions.

Question 5

When a restorer sets up a drying system, what does 'negative air pressure' in a contained area mean?

Accepted Answer

Air pressure inside the containment is lower than outside, preventing contaminants from escaping

Answer

Negative air pressure means air pressure inside containment is lower than surrounding areas, so any air movement goes inward, preventing cross-contamination of unaffected areas.
