CPR Contents Cleaning & Decontamination Processes 2 — Questions and Answers
Question 1: Which cleaning method is most appropriate for removing soot from a delicate porcelain figurine after a fire loss?
- Ultrasonic cleaning (Correct answer)
- Dry ice blasting
- Hand washing with alkaline detergent
- Pressure washing
Correct answer: Ultrasonic cleaning
Ultrasonic cleaning uses high-frequency sound waves in a liquid bath to gently dislodge soot from delicate and intricate items without mechanical abrasion.
Question 2: When decontaminating contents after a sewage backup, what is the primary concern with porous materials such as upholstered furniture?
- Color fading from disinfectants
- Inability to fully remove microbial contamination (Correct answer)
- Structural damage from moisture
- Increased drying time
Correct answer: Inability to fully remove microbial contamination
Porous materials absorb Category 3 water contaminants deep into their fibers, making complete decontamination virtually impossible and typically requiring disposal.
Question 3: A restorer is cleaning electronics affected by smoke. Which step must occur BEFORE any wet cleaning method is attempted?
- Apply corrosion inhibitor
- Ensure the device is completely powered down and disconnected (Correct answer)
- Test for residual soot pH
- Document serial numbers
Correct answer: Ensure the device is completely powered down and disconnected
All power sources must be disconnected from electronics before any wet cleaning to prevent electric shock and short-circuit damage.
Question 4: The term 'ozone treatment' in contents decontamination is primarily used to address which type of contamination?
- Mold spores
- Malodors from fire or smoke (Correct answer)
- Biological pathogens from sewage
- Lead-based paint particles
Correct answer: Malodors from fire or smoke
Ozone is a powerful oxidizer that reacts with and neutralizes odor-causing molecules, making it effective for smoke and fire malodor remediation.
Question 5: What does the IICRC S500 standard recommend when contents are exposed to Category 2 water?
- All contents must be discarded immediately
- Contents may be restored if properly cleaned and disinfected (Correct answer)
- Only hard-surface contents can be salvaged
- Contents must be tested by a certified lab before cleaning
Correct answer: Contents may be restored if properly cleaned and disinfected
The S500 standard allows Category 2 water-affected contents to be restored through proper cleaning and disinfection protocols when completed promptly.
Question 6: Which personal protective equipment (PPE) is required when handling contents contaminated with sewage (Category 3 water)?
- Safety glasses only
- Latex gloves and dust mask
- Full Tyvek suit, gloves, N95 respirator, and eye protection (Correct answer)
- Hard hat and steel-toed boots
Correct answer: Full Tyvek suit, gloves, N95 respirator, and eye protection
Category 3 water contains harmful pathogens that require full barrier PPE including impermeable suits, gloves, respiratory protection, and eye protection.
Question 7: A pack-out inventory system is used in contents restoration primarily to:
- Calculate depreciation values for insurance claims
- Track and document each item removed from a loss site (Correct answer)
- Determine which items require ultrasonic cleaning
- Schedule drying chamber capacity
Correct answer: Track and document each item removed from a loss site
A pack-out inventory system documents every item removed from the loss site with descriptions, photos, and condition notes to maintain chain of custody and accountability.
