HAZWOPER 40 CERTIFICATION
EVALUATION TEST PAPER 2026
QUESTIONS AND SOLUTIONS GRADED A+
●● Learning Objectives
At the completion of this lesson, you will be able to:.
Answer: Name the six points a decontamination (decon) plan should
address.
List six Standard Operating Procedures (SOPs) for decontamination that
minimize contact with waste and the potential for contamination.
Identify five factors that may affect the degree of permeation.
Discuss the two factors that must be taken into consideration in
selecting a decon method.
Compare and contrast decon steps by PPE level.
Describe a basic six-step decontamination line.
●● Introduction.
,Answer: Hazardous workplaces must have decontamination plans in
place as part of a more comprehensive site health and safety program
before actual operations begin. Decontamination procedures are a
component of a site-specific health and safety plan (HASP) and must be
developed and directly communicated to workers. Protective clothing
and equipment must be decontaminated, cleaned, laundered, maintained,
and replaced when no longer useful. Under certain circumstances,
decontamination itself can cause concerns, for instance, with reactive
substances, so care must be taken to understand potential dangers and
avoid them altogether.
●● Lesson Focus
This lesson focuses on the following topics:.
Answer: Decontamination
Decontamination Plan
Levels of Contamination
Decontamination Methods
Testing for Effectiveness
, Decontamination Facility Design
Decontamination Selection
Emergency Decontamination
●● Decontamination.
Answer: Decontamination, or decon, is the process of removing or
neutralizing contaminants that have accumulated on workers and
equipment. It is critical to worker health and safety at hazardous waste
sites. Decontamination protects all site personnel by reducing the
transfer of harmful materials into clean areas and helps to prevent the
mixing of incompatible chemicals. Decontamination also protects the
community by preventing uncontrolled transportation of contaminants
from the site.
●● Decontamination Plan.
Answer: A decontamination plan should be developed before any
operations begin with hazardous substances. The Decontamination Plan
is part of the site health and safety program. The decontamination plan
should:
Establish methods and procedures
Determine appropriate decon methods
Determine number and layout of decon stations
