CPR Contents Cleaning & Decontamination Processes 2

Question 1

Which cleaning method is most appropriate for removing soot from a delicate porcelain figurine after a fire loss?

Accepted Answer

Ultrasonic cleaning

Answer

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?

Accepted Answer

Inability to fully remove microbial contamination

Answer

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?

Accepted Answer

Ensure the device is completely powered down and disconnected

Answer

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?

Accepted Answer

Malodors from fire or smoke

Answer

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?

Contents may be restored if properly cleaned and disinfected

Answer

The S500 standard allows Category 2 water-affected contents to be restored through proper cleaning and disinfection protocols when completed promptly.
