Questions (100 Total)
1. According to TAC §78.50, who must perform a mold assessment before remediation begins in Texas?
A. The property owner
B. A licensed mold assessment consultant
C. The mold remediation contractor
D. Any certified inspector
Rationale: TAC §78.50(a) requires that a mold assessment be performed by a licensed mold
assessment consultant before any remediation can begin. This ensures an unbiased evaluation of the
extent of contamination and appropriate scope of work.
2. What is the minimum containment requirement for a mold remediation project involving 25 square
feet of contaminated surface area?
A. No containment required
B. Limited containment (plastic sheeting over openings, negative air not required)
,C. Full containment with negative air pressure
D. Sealing the entire building
Rationale: Per TAC §78.82(b), limited containment is required for projects between 25 and 100 sq ft.
Full containment with negative air is required for >100 sq ft. Projects ≤25 sq ft may use simplified
procedures but still require moisture control and cleaning.
3. Which type of respirator is required for mold remediation work involving more than 10 square feet of
contamination?
A. Dust mask (N95)
B. Half-face or full-face respirator with N-, R-, or P-100 filters
C. Surgical mask
D. No respirator needed if ventilation is adequate
Rationale: TAC §78.84(a)(1) mandates a NIOSH-approved half-face or full-face respirator with
N-100, R-100, or P-100 filters for all remediation work exceeding 10 sq ft. N95 masks are insufficient for
mold spores during active disturbance.
4. After completing mold remediation, when must the post-remediation verification (clearance) be
performed?
A. Within 7 days of project completion
B. Before the containment is removed and reoccupancy occurs
C. Only if requested by the client
D. Within 30 days
Rationale: TAC §78.90(c) requires that post-remediation verification be conducted by a licensed mold
assessment consultant before containment is dismantled and the area is reoccupied to ensure
effectiveness of remediation.
5. How long must a mold remediation contractor retain project records in Texas?
A. 1 year
B. 2 years
C. 3 years
D. 5 years
, Rationale: TAC §78.100(b) requires contractors to maintain all project records—including contracts,
assessments, work plans, and clearance reports—for at least three (3) years from the date of project
completion.
6. Mold growth indoors primarily requires:
A. High temperatures only
B. Moisture, organic material, and time
C. Direct sunlight
D. Low humidity
Rationale: Mold requires moisture (from leaks, condensation, or flooding), a food source (wood,
drywall, dust), and 24–48 hours to begin growing. Controlling moisture is the key to prevention—per
EPA and TDLR guidance.
7. A mold remediation contractor must provide the client with a written contract that includes all
EXCEPT:
A. Scope of work
B. Estimated cost
C. The contractor’s personal financial statements
D. Timeline for completion
Rationale: TAC §78.70(a) requires a written contract with scope, cost, timeline, and license
number—but not personal financial information. Contracts must be clear, accurate, and compliant with
TDLR standards.
8. Which of the following is prohibited under Texas mold law?
A. Using HEPA vacuuming
B. Performing both mold assessment and remediation on the same project
C. Wearing PPE
D. Conducting post-remediation testing
Rationale: TAC §78.55 prohibits a licensee from performing both assessment and remediation on the
same project to avoid conflict of interest. This ensures objective evaluation and ethical practice.
9. What is the primary purpose of negative air pressure in full containment?
A. To cool the work area
