A typical microbial-remediation project follows the proper job sequencing steps: ✔Correct
Answer--Identifying and stopping the source of moisture
-setting up containment
-establishing negative air
-removing contaminated building materials
-clean surfaces
-dry the affected areas
-conducting post-remediation evaluation
Wet content materials ✔Correct Answer-Odors that are detected in water-damaged buildings can
be caused by wet structural assemblies or
Microorganism's metabolism ✔Correct Answer-Microbiological volatile organic compounds
(MVOC's) are by-products of
Mycotoxins ✔Correct Answer--toxins produced by a fungus
-produced by some molds under certain conditions
-present in the cell walls of fungal spores and hyphae
Aflatoxin ✔Correct Answer--mycotoxins that are known to be carcinogenic
can cause damage to liver
mold spores ✔Correct Answer-very small, typically found to be 2 to 20 microns in diameter in an
indoor environment
micron ✔Correct Answer-one millionth of a meter (1/1,000,000)
Sporulation ✔Correct Answer-molds as fungal organisms begin to produce and release spores into
the environment in this process
Allergenic and/or contain toxins ✔Correct Answer-Viable spores are in effect "alive" and can start
new colonies
Settled spores ✔Correct Answer-Spores that have settled or landed on an indoor surface but are
not actively growing on the surface
Stachybotrys ✔Correct Answer--Requires a high level of water activity, and groes best when
continuous contact with moisture. Stachy is one of the many mycotoxin-producing molds
-Take 8 weeks to begin to colonize
-Under ideal conditions, will grow in 7-12 days
penicillin and aspergillus ✔Correct Answer--Two most commonly found molds
-Takes 14 days to grow but in lab takes 48-72 hours
-Respirable
-Xerophilic
