  1. A remediation crew is working in a building with active HVAC. At minimum, what must be done to the HVAC system serving the containment area before starting mold disturbance work?

    Answer: Seal all supply and return registers within the containment with poly sheeting and tape

    All HVAC registers within the remediation containment must be sealed to prevent spore-laden air from being drawn into the duct system and distributed throughout the building.

  2. Which of the following surfaces is considered NON-POROUS and can typically be cleaned and retained rather than demolished during mold remediation?

    Answer: Ceramic tile with intact grout

    Ceramic tile is non-porous and can be cleaned and disinfected; porous materials like drywall, OSB, and fiberglass insulation must be removed if mold growth is present.

  3. A CMA assessor writes a remediation protocol specifying that workers must use supplied-air respirators (SARs). What scenario MOST justifies this elevated PPE level over standard N95 or half-face respirators?

    Answer: Remediation involves Stachybotrys-contaminated materials in a confined space with poor ventilation

    Highly toxic mold species like Stachybotrys in confined spaces with poor ventilation create conditions that may warrant supplied-air respirators to provide the highest level of respiratory protection.

  4. Which regulation requires employers to maintain records of worker exposure to mold and the results of any air monitoring performed during remediation activities?

    Answer: OSHA 29 CFR 1910.1020 (Access to Employee Exposure and Medical Records)

    OSHA 29 CFR 1910.1020 requires employers to maintain and provide access to employee exposure and medical records, including industrial hygiene sampling results.

  5. When setting up a decontamination chamber (airlock) for a mold remediation project, what is the correct sequence of zones from contaminated to clean?

    Answer: Work area → shower/wash station → gear removal room → clean area

    Workers exit through a sequence of: work area → shower/wash station to remove gross contamination → gear removal room to doff PPE → clean area to prevent tracking contamination.

  6. A post-remediation air sample reveals elevated Cladosporium counts indoors but levels are consistent with outdoor samples taken the same day. What is the MOST likely interpretation?

    Answer: The result represents normal fungal ecology consistent with outdoor infiltration

    Cladosporium is ubiquitous outdoors, and indoor levels matching outdoor levels indicate normal infiltration rather than an amplification site, supporting successful clearance.

  7. Under Florida's Mold-Related Services law, which activity requires a licensed Mold Assessor rather than a Mold Remediator?

    Answer: Writing a mold remediation protocol and specifying the scope of work

    Florida law prohibits the same entity from performing both assessment and remediation; writing a remediation protocol (assessment function) requires a licensed Mold Assessor.
