IICRC WRT Containment, Controlled Demolition and Material Removal

Question 1

What is the purpose of negative air pressure in a containment?

Accepted Answer

To keep airflow moving into the containment so contaminants don't escape

Answer

Exhausting air from the containment, typically through HEPA filtration, creates lower pressure inside, so air leaks inward rather than outward.

Question 2

What is the goal of controlled demolition during water damage restoration?

Accepted Answer

Remove only unsalvageable or contaminated materials while limiting the spread of debris and contaminants

Answer

Controlled demolition removes what cannot be restored, such as Category 3 porous materials, while preserving salvageable materials and containing dust.

Question 3

Which item is commonly used to build a containment barrier?

Accepted Answer

Polyethylene sheeting with a zippered door

Answer

Poly sheeting sealed at the edges, with a zipper entry, isolates the work area and controls access.

Question 4

Which approach is generally appropriate for non-porous materials affected by Category 3 water?

Accepted Answer

Clean and disinfect them if they are structurally sound

Answer

Non-porous materials like metal, glass, and sealed hard plastic can be decontaminated by cleaning and disinfecting.

Question 5

Which PPE is appropriate during demolition of materials affected by Category 3 water?

Accepted Answer

Disposable coveralls, gloves, eye protection, and a respirator suited to the hazard

Answer

Contaminated demolition exposes workers to pathogens and dust, so full protective gear including respiratory protection is required.
