HAZWOPER Decontamination Procedures & PPE Usage 3

Question 1

A worker performing emergency response to a chlorine spill is wearing a chemical-resistant suit with SCBA. What PPE level is this?

Accepted Answer

Level A

Answer

Level A PPE consists of a fully encapsulating vapor-tight chemical protective suit combined with SCBA, providing the highest level of skin and respiratory protection.

Question 2

During doffing of chemical protective clothing, which area should be avoided to prevent self-contamination?

Accepted Answer

The outer surface of gloves

Answer

The outer surfaces of gloves and PPE should not be touched with bare hands during doffing because they may be contaminated; doffing procedures are designed to roll outward and contain contaminated surfaces.

Question 3

Which of the following is NOT a recognized limitation of air-purifying respirators (APRs) in hazardous waste operations?

Accepted Answer

They provide more airflow than SCBA units

Answer

APRs do not supply air and therefore do not provide more airflow than SCBA; they purify ambient air through filters or sorbents and cannot be used in IDLH or oxygen-deficient conditions.

Question 4

What is the correct sequence for donning multi-layered PPE to maintain integrity?

Accepted Answer

Inner gloves → suit → respirator → boots → outer gloves

Answer

The generally accepted sequence is inner gloves first (for dexterity), then suit, then respirator (sealed while still clean), then boots taped over the suit, then outer gloves taped to the suit.

Question 5

At a multi-agency hazmat response, the decontamination team discovers that a contaminated victim is ambulatory and uncooperative. What is the priority action?

Accepted Answer

Attempt to verbally guide the victim to the decon corridor

Answer

Emergency responders should attempt calm verbal communication to guide the victim into decontamination; force is a last resort, and the immediate goal is preventing contaminant spread while ensuring victim safety.
