Quiz Flashcards
The FOUR Principles of Drying are
R - Remove Excess
E - Evaporation
D - Dehumidification (Ventilation)
T - Temperature Control
The ANSI/IICRC S500 defines the Category of water which ORIGINATES FROM A SANITARY WATER SOURCE and does not pose substantial risk to humans is
Category 1
The CLASS OF WATER with the GREATEST EVAPORATION potential amount of evaporation, due to the greatest amount of absorption (more than ~40% floor, wall, and ceiling area combined) is
Class 3
The CLASS OF WATER with wet materials with low permeance/porosity and deep pockets of saturation with water that is hidden, trapped or bound with LOW EVAPORATION,
- is also known as Class:
- is often referred to as:
Class 4
AKA - Special Drying Situation
The CLASS OF WATER with the LEAST amount of water and EVAPORATION (small area – comprising less than ~5% of floor, wall, and ceiling area combined) is
Class 1
When water contains significant contamination and potential to cause discomfort or sickness, it is called
Category 2
A water intrusion with wet porous materials representing ~5% - to- less than ~40% of
combined floor, wall, and ceiling surface area (carpet, gypsum board, fiber-fill insulation) is known as Class:
Class 2
Monitoring to document and adjust goals should be performed at least:
DAILY
An IEP, used to perform services beyond the expertise of the restorer, which may be needed initially, or at the end of a project, is an acronym for
Indoor Environmental Professional
Two documents to determine if evaporation and dehumidification process is adequate are
- MOISTURE MAP (validates moisture content and location)
& - DAILY HUMIDITY RECORD (helps determine if evaporation and dehumidification
process is adequate)
Before wearing respirators, the “Company Protection Plan” states all employees shall be: a. b. and trained to c.
a) medical evaluation
b) fit tested
c) trained: don, doff, clean/maintain
Light wand will most effectively extract which type carpet installation?
direct glue-down
The most effective principle to reduce drying time is:
Thorough and meticulous extraction
The tool used to safely extract water from hard surfaces (e.g., concrete, wood, vinyl) without damaging finished flooring or the extraction wand is:
and is also known as:
hard surface wand (a.k.a., vacuum squeegee)
(FILL-IN FORMULA)
The formula to compute gallons of standing water is written as:
a) _______x ___________÷ ______ = (cubic footage) x _______ = (_________to pump-out)
L x H (sq ft) (x Depth) ÷ 12 = (cubic footage)
x 7.48 = (gallons of water to pump-out)
The approximate number of gallons in a 22 ft. x 22 ft. (6.7 m x 6.7 m) basement flooded with 3 ft. 4 inches (40 inches or 1.0 m) of water is:
12,067
[22x22 (x40)=19,360
19,360÷12=1613.3 or 1614
1613.3x7.48=12,067.7
Two tools to use when relieving tension on carpet while disengaging at corners, are:
- )
- )
- Knee Kicker
2. Carpet Awl
Once inspected and determined if carpet is glue-down…or…if installed over cushion (padding), the easiest of the two installation processes to extract is:
a)
direct glue-down
The government regulatory AGENCY dictating employee health and safety in the workplace is:
a)
OSHA (Occupational Safety and Health Administration)
When using conventional refrigerant dehumidifiers in a Class 2 water loss containing 12,000 ft3 (339 m3), the initial AHAM-rated capacity recommended (pints per day) is:
300
On #1,
(refrigerant dehumidifiers in a Class 2 water loss containing 12,000 ft3 (339 m3))
if a dehumidifier which processes 64 pts. at AHAM is used, the recommended
number of units to install is:
5
When using low grain refrigerant (LGR) dehumidifiers on a Class 3 that is capable of removing 130 pints (61 liters) at AHAM, the recommended # of units to be installed initially within drying chamber of 36,000 ft3 (1019.4 m3) is:
7
When using desiccant dehumidification to dry a structure with deeply-held bound water in plaster walls or cupped hardwood flooring in 40 ft x 65 ft. (12m x 19.5m) with 9-foot (2.7 meter) ceilings, the initial CFM for dehumidification is:
1170
On #4,
(deeply held water; 40 ft x 65 ft. (12m x 19.5m) with 9-foot (2.7 meter) ceilings)
if the desiccant used processes 385 cfm, the recommended number of units is:
4
