Flood Restoration General Safety 2 — Questions and Answers
Question 1: Before entering a flood-damaged structure, what should be shut off first if it is safe to access the panel?
- The electrical power (Correct answer)
- The interior lighting
- The HVAC thermostat
- The water heater pilot
Correct answer: The electrical power
Standing water and energized circuits create electrocution hazards, so electrical power must be de-energized before entry.
Question 2: Category 3 (black) water is most accurately described as which of the following?
- Grossly contaminated water containing pathogens or toxins (Correct answer)
- Clean water from a supply line
- Slightly used water from a dishwasher
- Condensate from an AC unit
Correct answer: Grossly contaminated water containing pathogens or toxins
Category 3 water is grossly unsanitary and may contain sewage, chemicals, or harmful microorganisms.
Question 3: Which respiratory protection is generally the minimum for entering a mold-contaminated flood site?
- An N95 filtering facepiece respirator (Correct answer)
- A simple surgical mask
- A bandana over the face
- No protection is needed outdoors
Correct answer: An N95 filtering facepiece respirator
An N95 respirator filters airborne mold spores and particulates that a surgical mask cannot.
Question 4: What is the primary danger of running a gasoline generator inside an enclosed flooded basement?
- Carbon monoxide poisoning (Correct answer)
- Excessive noise
- Battery acid leaks
- Static electricity
Correct answer: Carbon monoxide poisoning
Generators emit carbon monoxide, an odorless gas that can be fatal in enclosed spaces.
Question 5: When lifting heavy, water-soaked materials, what technique reduces back injury?
- Bend the knees and lift with the legs (Correct answer)
- Bend at the waist and twist
- Lift quickly with arms fully extended
- Hold the load away from the body
Correct answer: Bend the knees and lift with the legs
Lifting with the legs and keeping the load close protects the spine from strain.
Question 6: Why should you assume the structural integrity of a flooded building may be compromised?
- Water can weaken foundations, floors, and supports (Correct answer)
- Water always strengthens wood
- Flooding only affects cosmetic finishes
- Saturation has no effect on drywall
Correct answer: Water can weaken foundations, floors, and supports
Prolonged saturation can undermine foundations and weaken load-bearing materials, risking collapse.
Question 7: What is the correct first action upon discovering a natural gas odor at a flood site?
- Evacuate and call the gas company from a safe distance (Correct answer)
- Light a match to locate the leak
- Turn on lights to see better
- Keep working with windows closed
Correct answer: Evacuate and call the gas company from a safe distance
Evacuating without creating sparks and reporting from a safe distance prevents an explosion.
