Flood Restoration Knowledge 2 — Questions and Answers
Question 1: Which water damage category involves grossly contaminated water containing sewage or floodwater from rivers?
- Category 1
- Category 2
- Category 3 (Correct answer)
- Category 4
Correct answer: Category 3
Category 3 water (black water) is grossly unsanitary and includes sewage and river floodwater.
Question 2: What instrument is most commonly used to measure moisture content in building materials?
- Anemometer
- Moisture meter (Correct answer)
- Manometer
- Hygrometer
Correct answer: Moisture meter
A moisture meter measures the moisture content within materials like wood and drywall.
Question 3: During structural drying, what does a thermo-hygrometer primarily measure?
- Material density
- Temperature and relative humidity (Correct answer)
- Water pH
- Airflow speed
Correct answer: Temperature and relative humidity
A thermo-hygrometer measures air temperature and relative humidity to assess drying conditions.
Question 4: Which class of water loss involves the least amount of water and slowest evaporation rate?
- Class 1 (Correct answer)
- Class 2
- Class 3
- Class 4
Correct answer: Class 1
Class 1 is the least amount of water absorption with minimal evaporation load.
Question 5: What type of dehumidifier extracts moisture using a moisture-absorbing wheel rather than condensation?
- Refrigerant dehumidifier
- Desiccant dehumidifier (Correct answer)
- LGR dehumidifier
- Conventional dehumidifier
Correct answer: Desiccant dehumidifier
Desiccant dehumidifiers use a hygroscopic wheel to adsorb moisture from the air.
Question 6: Why should electrical power be assessed before entering a flooded structure?
- To save energy
- To prevent electrocution hazards (Correct answer)
- To keep lights on for photos
- To run dehumidifiers faster
Correct answer: To prevent electrocution hazards
Standing water near live electrical systems creates a serious electrocution risk that must be eliminated first.
Question 7: What is the recommended first documentation step upon arriving at a water-damaged site?
- Begin demolition
- Photograph and record initial conditions (Correct answer)
- Apply antimicrobial
- Remove all furniture
Correct answer: Photograph and record initial conditions
Documenting initial conditions with photos protects both the client and restorer and supports insurance claims.
