CPR Fire, Soot & Odor Remediation 4

Question 1

Which material is most likely to require full replacement rather than cleaning after heavy smoke exposure due to its porous nature?

Accepted Answer

Fiberglass insulation

Answer

Fiberglass insulation is extremely porous and absorbs smoke odors permanently, making cleaning impractical and replacement necessary.

Question 2

A restorer performing a 'sniff test' walk-through after final deodorization detects lingering odor in one bedroom. The NEXT step should be:

Accepted Answer

Source-find the remaining odor in that specific room before retreating

Answer

A targeted source-finding inspection must be performed to locate the specific odor source before applying any additional treatment.

Question 3

Personal protective equipment (PPE) required when cleaning heavy soot deposits typically includes:

Accepted Answer

Full-face respirator with P100 filters, Tyvek suit, and chemical-resistant gloves

Answer

Heavy soot contains carcinogenic particles and chemical residues requiring a full-face P100 respirator, protective suit, and chemical-resistant gloves.

Question 4

What does the term 'ionization' refer to in the context of fire odor remediation?

Accepted Answer

Applying charged particles to neutralize odor molecules in the air

Answer

Ionization devices release charged particles that attach to airborne odor molecules and contaminants, causing them to drop out of the air.

Question 5

When cleaning soot-affected contents using ultrasonic cleaning, the process works by:

Accepted Answer

Using high-frequency sound waves in a cleaning solution to create cavitation bubbles that lift residue

Answer

Ultrasonic cleaners use high-frequency sound waves to create microscopic cavitation bubbles that implode against surfaces, dislodging soot and residue.
