Mold Inspection Standards of Practice
What this domain tests
The Mold Inspection Standards of Practice domain tests whether you understand the boundary between a visual, non-invasive mold inspection and work that requires engineering, medical, or remediation expertise. The exam focuses on the standard of care: inspect readily accessible, visible systems and components; report moisture intrusion, water damage, musty odors, visible suspected mold growth, and conditions conducive to mold growth; and clearly state the limitations of the inspection.
Core rules
- The inspection is visual and non-invasive. You are not required to move stored goods, furniture, or ceiling tiles, dismantle equipment, open walls, or enter unsafe spaces.
- You are not required to determine the cause of moisture, identify mold species, or assess health risk. Those tasks are outside the mold inspector's scope; recommend a qualified specialist when needed.
- Document with photographs, moisture readings where used, location, and extent. Report both observed growth and the moisture condition that supports it.
- The report must be clear about what was inspected, what was not inspected, and why. Concealed spaces are excluded unless specifically contracted.
- Sampling is not a substitute for inspection; if sampling is performed, it must follow the sampling standard.
Worked example
You inspect a bathroom vanity. Stored items block the cabinet floor, and visible dark staining appears at the toe kick. The correct response is to photograph the staining, note the limitation (stored items and concealed cabinet interior), report the visible moisture indicator, and recommend further evaluation after contents are removed. You do not move the client's belongings, remove the vanity, or call the stain "toxic black mold" without laboratory analysis. If the client wants confirmation, sampling may be offered under the sampling standard.
Traps
Declaring a mold species from color; promising that remediation will "pass clearance"; treating the standard as a mandate to open walls; omitting limitations; and confusing a condition conducive to mold with confirmed mold growth.
