Guide Questions And Answers Verified
100% Correct
Environmental Protection Agency (EPA) - ANSWER -The government agency
that sets guidelines and regulations for mold remediation practices.
Negative air pressure system - ANSWER -A system established in a containment
area during mold remediation to reduce the risk of cross-contamination.
Drywall - ANSWER -A porous material that is most susceptible to mold growth in
a damp environment.
Recommended humidity level to prevent mold growth - ANSWER -Humidity
levels should be maintained below 60% indoors.
Mycotoxins - ANSWER -Toxins produced by certain molds that can lead to
neurological issues in exposed individuals.
Goal of mold remediation - ANSWER -To return the property to a pre-loss
condition.
Common symptom of exposure to mycotoxins - ANSWER -Neurological issues.
Addressing plumbing leaks promptly - ANSWER -Promptly addressing water
leaks and moisture issues can help homeowners prevent mold growth in their
living spaces.
Removing and cleaning contaminated components - ANSWER -To address mold
growth in HVAC systems effectively, contaminated components must be removed
and properly cleaned to prevent further contamination.
, Using biocides in mold remediation - ANSWER -Biocides are used to eliminate
mold spores and prevent further growth in contaminated areas during remediation.
Using fans to spread mold spores - ANSWER -Using fans can inadvertently
spread mold spores to unaffected areas, leading to further contamination and
complicating the remediation process.
Post-remediation verification - ANSWER -Post-remediation verification is crucial
to confirm that the remediation was successful and that the property is safe from
mold contamination.
Establishing a containment area during mold remediation - ANSWER -
Containment areas are essential in preventing the spread of mold spores to clean
areas during remediation.
Negative air pressure in a containment area - ANSWER -Negative air pressure
creates an airflow that prevents mold spores from escaping containment.
Negative air pressure - ANSWER -Creates an airflow that prevents mold spores
from escaping containment.
Containment material - ANSWER -Plastic sheets are commonly used in
containment areas as they are impermeable and help to contain mold spores
effectively.
Size of containment area considerations - ANSWER -The type of mold present is
NOT a consideration when determining the size of a containment area for mold
remediation.
Purpose of negative air pressure differentials - ANSWER -To enhance airflow and
prevent cross-contamination.
HEPA - ANSWER -Stands for High Efficiency Particulate Air.
