1. Which regulatory body is primarily responsible for licensing
contractors performing disaster restoration work in Virginia?
A. Virginia Department of Health (VDH)
B. Virginia Department of Professional and Occupational Regulation (DPOR)
C. Environmental Protection Agency (EPA)
D. Occupational Safety and Health Administration (OSHA)
Correct Answer: B. Virginia Department of Professional and Occupational
Regulation (DPOR)
Rationale: The DPOR is the primary state agency that regulates contractor
licensing in Virginia, including restoration contractors performing
construction, repair, and remediation work. While EPA and OSHA set
,federal standards and VDH handles public health-related issues, DPOR is
the licensing authority that issues Class A, B, and C contractor licenses.
2. Under Virginia law, at what minimum combined value of labor and
materials is a contractor license generally required to legally perform
restoration work?
A. $500
B. $1,000
C. $5,000
D. $10,000
Correct Answer: B. $1,000
Rationale: Virginia contractor licensing requirements typically apply when
the total value of a construction or restoration contract, including labor
and materials, is $1,000 or more. This threshold triggers the requirement
for appropriate contractor licensure under Virginia Code § 54.1-1100.
3. Which license class in Virginia allows contractors to perform unlimited-
value projects?
A. Class C
B. Class B
C. Class A

,values, making them suitable for large-scale disaster restoration and

risk of mold growth after water intrusion?
A. Exposure to sunlight within 24 hours
B. Rapid dehumidification within 48 hours
C. Delayed drying beyond 24–48 hours
D. Use of antimicrobial sealants immediately
Correct Answer: C. Delayed drying beyond 24–48 hours
Rationale: Mold growth is significantly accelerated when moisture is not
controlled within the first 24–48 hours after water intrusion. This time
window is critical in restoration science because prolonged damp
conditions allow microbial amplification on porous materials.
5. Which classification system is used to define water contamination
levels in restoration projects?
A. EPA Hazard Ranking System
B. OSHA Hazard Communication Standard
C. IICRC S500 Standard
D. Virginia Uniform Statewide Building Code
Correct Answer: C. IICRC S500 Standard

A. Clean drinking water from supply lines
B. Slightly contaminated gray water
C. Highly contaminated sewage or floodwater
D. Condensation from HVAC systems only

remediation?
