Question 1

When applying antimicrobials via ULV (ultra-low volume) fogging, the technician must ensure that:

Accepted Answer

The area is vacated and ventilated per the product label instructions

Answer

ULV fogging disperses fine airborne droplets that pose an inhalation risk, so the area must be vacated and properly ventilated as directed by the product label.

Question 2

According to EPA standards, a surface sanitizer must reduce the bacterial population by at least:

Accepted Answer

99.9% (3-log reduction)

Answer

The EPA defines a sanitizer as achieving at least a 99.9% (3-log) reduction in bacterial populations on inanimate surfaces.

Question 3

A disinfectant differs from a sanitizer primarily because a disinfectant must:

Accepted Answer

Kill a broader spectrum of pathogens including viruses and fungi

Answer

Disinfectants are formulated and tested to kill a broader spectrum of pathogens (bacteria, viruses, and fungi), whereas sanitizers primarily target bacteria.

Question 4

Which PPE combination is most critical when applying concentrated antimicrobial solutions?

Accepted Answer

Chemical-resistant gloves, eye protection, and appropriate respiratory protection

Answer

Chemical-resistant gloves, eye protection, and respiratory protection guard against the primary exposure routes (skin, eyes, inhalation) when handling concentrated antimicrobials.

Question 5

What is the primary purpose of an antimicrobial encapsulant applied during mold remediation?

Accepted Answer

To seal residual mold spores after remediation and prevent their release into the air

Answer

Antimicrobial encapsulants coat and seal residual spores after remediation is complete, preventing them from becoming airborne.
