HAZWOPER 40 - Lesson 10 Decontamination Graded A+
Lesson Description ✔️This lesson, Decontamination, explains how to establish a site
decontamination plan and the importance of such a plan. Decontamination is the process of
removing or neutralizing contaminants that have accumulated both on workers and on
equipment at a waste site.
The lesson emphasizes the importance of evaluating the levels of contamination present onsite
so that the appropriate decontamination methods can be selected and standard operating
procedures established. Finally, how to design a decontamination facility to control the various
levels of exposure found onsite is covered, along with a detailed review of decontamination line
processes and the importance of emergency preparedness.
Learning Objectives
At the completion of this lesson, you will be able to: ✔️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 ✔️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: ✔️Decontamination
Decontamination Plan
Levels of Contamination
Decontamination Methods
Testing for Effectiveness
Decontamination Facility Design
Decontamination Selection
Emergency Decontamination
Decontamination ✔️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.
