building has mold?- --- correct answer ---
--- correct answer --- Visual
,57. What measurements could a mold assessor take to determine
if a building has the potential for mold growth?--- correct answer --
- -Humidity
-Temperature
58. A mold assessor has collected particulate data, how would
they use this data to determine if a room has a problem?--- correct
answer --- Compare the readings against outside measurements.
59. As a Mold Assessment Consultant, what are some common
hazardous build- ing materials that you might ask the building
owner about?--- correct answer --- Lead and Asbestos
60. A mold assessor is collecting spore trap samples, assume a
flow rate of 15 liters per minute (lpm. You run the air sampling
pump for 5 minutes. What is the
total volume in luters using the formal, Volume = Flow rate times
Time (V=FR x T)?--- correct answer --- 75 Liters
61. A mold assessor is collecting mold samples on a filter media,
assume a flow rate of 28 liters per minute (lpm). You run the air
sampling pump for 3 minutes. What is the total volume in liters
using the formula; Volume = Flow Rate times Time (V=FR x T)?---
correct answer --- 84 Liters
62. Mold assessors could use what to indicate that a building has
a potential for mold growth?--- correct answer --- Condensation on
the inside of windows, and or high humidity levels.
63. Mold Assessment Consultant (MAC) or Mold Assessment
Technician (MAT) write a for the client. --- correct answer ---
Mold assessment report
,64. The Mold Assessment Consultant (MAC) prepares a mold
management plan for the client to indoor mold growth.---
correct answer --- Prevent and Control
65. The Mold Assessment Consultant (MAC) can write the mold
assessment report, mold management plan, mold clearance and
(which is needed to write the mold work plan by the Mold
Remediation Contractor (MRC).--- correct answer --- Mold Protocol
66. The Mold Assessment Consultant (MAC) who writes the
for the client lists quantities of material to be treated or
removed, locations, proposed meth- ods and clearance criteria.---
correct answer --- Mold Protocol
67. The Mold Remediation Contractor (MRC) write the mold
which may have standard operating procedures.--- correct
answer --- Work plan
68. The Mold Remediation Contractor (MRC) must give the wrok
plan to the client how far in advance prior to starting work, specific
instructions also called Standard Operating Procedures (SOP) for
mold removal.--- correct answer --- One Calendar Day
69. The MAC, MAT, and MRC provide the to the client (customer
or building owner) at least 1 caldar day before the project begins.---
correct answer --- Consumer Mold Information Sheet (CMIS)
70. The MRC and MAC provide the Certificate of Mold Damage
Remediation (CMDR) after the project is done and within how many
day?--- correct answer --- 10
71. What is a bioaerosol?--- correct answer --- A suspension of
tiny biological particles in the air that were released by a living
, organism or contain a living organism, which can include bacteria,
viruses, mold, spores, hyphae, mycotoxins, pollen, or fragments of
plants and animals.
72. What is a viable air sample?--- correct answer --- Samples
that are taken on some growth media and subsequently incubated
for mold propagules (spores and hyphal fragments) to germinate
and form colonies. The resulting colonies are enumerated and/or
transferred to other media for identification. Results are presented
as a listing of recovered molds and their corresponding number of
colony forming units per cubic meter of air (CFU/m^3)
73. What is a non-viable air sample?--- correct answer ---
Samples that are taken on some sticky media or on a filter
membrane or tape subsequently examined directly under a
microscope for enumeration and indentification of mold spores and
hyphal fragments without culturing. In other words, samples are
taken for analyses by direct microscopic examination (DME) based
on morphology (size, shape, color, etc).
74. What are some examples of non-viable samples?--- correct
answer --- Spore traps by Allergenco-D, Zenfon Air-O-Cell, and tape
lifts.
75. What method do you use and what type of result do you get
when samples are collected and lab analyzed using non-viable,
spore trap, airborne material samplers such as an Air-O-Cell?---
correct answer --- The ditterent species of mold and/or spores are
counted up and a QUANTITATIVE, non-viable result is given.
76. For samplers such as the Anderson sampler or the Bio-cassette
what method will be used and what type of result will you receive
