Answer: Floorcovering Carpet Installation Methods
◉ In-place, full float, partial float
Answer: Floorcovering Carpet Drying Methods
◉ Woven - Axminster, Wilton; usually natural fibers; tufted -
primarily synthetic
Answer: Floorcovering Carpet Construction
◉ Separation of primary - secondary backings; laminate strength
loss up to 85% when wet
Answer: Delamination
◉ Also known as padding, underlay
Answer: Floorcovering Cushion
,◉ Foam (prime, bonded urethane); rubber; felt (hair/jute,
synthetic); porous and non-porous
Answer: Floorcovering Cushion Types
◉ Strip wood, plank wood, engineered - laminated wood, parquet
Answer: Floorcovering Wood
◉ At or over 16% MC
Answer: Non-Destructive Fungal Growth
◉ At or over 20% MC
Answer: Destructive Fungal Growth
◉ At or over 28 - 30% MC
Answer: Fiber Saturation
◉ (cupping; crowning; buckling; heaving)
Answer: Moisture Damage Types
◉ Dry within 2-4 percentage points of normal EMC
Answer: Drying Goal
,◉ Organic food source (cellulose), moisture (or high humidity) -
especially when greater than 60% RH, temperature (most prolific
68-86º F. / 20-30º C.), stagnant air, time (some 1-2 days; others up to
10-12 days in chronic conditions)
Answer: Microbiology Conditions for Growth
◉ Standard and Reference Guide for Professional Mold Remediation
Answer: ANSI/IICRC S520

Answer: Indoor Environmental Professional (IEP)
◉ A potentially harmful metabolite produced by some fungi,
especially molds.
Answer: Mycotoxin
◉ A portion of the outer cell wall of some gram-negative bacteria.
When ingested or respired, endotoxins can cause fever, changes in
white blood cell counts, increased airway resistance, shock and even
death.
Answer: Endotoxin
◉ Study of the relationship between air, humidity and temperature
and their effect on various materials and comfort levels
, Answer: Psychrometry
◉ Chart consisting of lines and curves that shows the relationship
between air volume, temperature and relative humidity, and from
which a variety of other information (humidity ratio-gpp, dew point,
vapor pressure, etc.) relating to drying may be determined
Answer: Psychrometric Chart
◉ The temperature at which humidity in air reaches saturation
(100% RH) and will condense from that air to form condensation or
"dew" on surfaces.
Answer: Dew Point
◉ The process of changing a liquid to a vapor
Answer: Evaporation
◉ Damage sustained as a result of direct exposure with water.
Answer: Primary Damage
◉ Damage sustained from indirect or prolonged exposure to
disaster contaminants
Answer: Secondary Damage
