Question 1

Ultrasonic cleaning is best suited for which category of contents?

Accepted Answer

Hard, non-porous items such as ceramics, metals, and plastics

Answer

Ultrasonic cleaning uses high-frequency sound waves in a liquid medium and is most effective on hard, non-porous items like ceramics, metals, and plastics.

Question 2

Which cleaning method uses high-pressure hot water to remove soot and smoke residue from non-porous hard surfaces in a controlled environment?

Accepted Answer

Pressure washing in a contents cleaning facility

Answer

Pressure washing with hot water in a controlled facility effectively removes soot and smoke residue from durable non-porous surfaces without risking secondary damage to other items.

Question 3

When cleaning contents affected by a Category 3 (grossly contaminated) water loss, what additional step is required beyond standard cleaning?

Accepted Answer

Disinfection or antimicrobial treatment in addition to cleaning

Answer

Category 3 water losses involve grossly contaminated water, so contents must be disinfected or treated with antimicrobials after cleaning to eliminate pathogens.

Question 4

What is the correct sequence of steps when using dry sponge wiping to clean soot from a surface?

Accepted Answer

Wipe with a dry chemical sponge using straight strokes, replacing or rotating the sponge as it becomes loaded

Answer

Dry chemical sponges must be used dry with straight strokes to lift and trap soot particles; circular motions or moisture smear the residue further into the surface.

Question 5

Which odor-elimination technique is most appropriate for textiles and soft goods in a closed environment after cleaning?

Accepted Answer

Ozone treatment after all biological occupants have vacated the space

Answer

Ozone treatment is highly effective for deodorizing textiles and soft goods, but must be performed only after all humans, pets, and plants have vacated the treated space due to ozone's toxicity.
