2025
1. Which of the following is considered the first step in sewage
remediation?
A) Application of antimicrobial agents
B) Containment and control of affected area
C) Removal of standing water
D) Identification of affected materials
Correct ANS: C) Removal of standing water
©2024/2025
, Rationale: The first step in sewage remediation is to remove
standing water to prevent additional damage and mold growth.
2. What is the primary health risk associated with exposure to
untreated sewage?
A) Allergic reactions
B) Respiratory issues
C) Infectious diseases
D) Structural damage
Correct ANS: C) Infectious diseases
Rationale: Untreated sewage contains pathogens that can lead
to infectious diseases, posing significant health risks.
3. Which class of protective clothing is recommended for
sewage remediation workers?
A) Level A
B) Level B
C) Level C
D) Level D
