CPR Fire, Soot & Odor Remediation 2

Question 1

Which type of soot is typically produced by a fast-burning, high-oxygen fire involving synthetic materials?

Accepted Answer

Dry soot

Answer

Dry soot results from fast-burning, high-oxygen fires and is powdery, making it easier to vacuum than wet soot.

Question 2

When deodorizing a structure after fire damage, thermal fogging works best because it:

Accepted Answer

Mimics smoke penetration to neutralize odor molecules

Answer

Thermal fogging generates a deodorizing fog that penetrates the same areas smoke did, neutralizing embedded odor molecules.

Question 3

Before applying an odor sealant to fire-damaged walls, the restorer should first:

Accepted Answer

Complete dry and wet cleaning of all surfaces

Answer

Sealants should only be applied after thorough cleaning, as sealing over residue traps contaminants and reduces adhesion.

Question 4

Which piece of equipment is most appropriate for removing loose, dry soot from a ceiling before wet cleaning?

Accepted Answer

HEPA vacuum

Answer

A HEPA vacuum captures fine soot particles without spreading them into the air, making it ideal for pre-cleaning ceilings.

Question 5

Protein fires (cooking fires) leave residue that is best described as:

Accepted Answer

Virtually invisible with a strong pungent odor

Answer

Protein residue is nearly invisible but creates a powerful odor and a thin varnish-like film on surfaces.
