Decontamination Plan
Give this one a try later!
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
Establish procedures to prevent contamination of clean areas
, Determine decon equipment needed
Establish methods for disposing of clothing and equipment
Decontamination Selection
Various methods for decontamination can be used. Each scenario is different, so
decontamination selection should be evaluated on a case-by-case basis. Some
factors to take into consideration include:
Give this one a try later!
• Equipment selection: When selecting equipment, consider whether the
equipment should be decontaminated, or if it should it be discarded.
• Disposal methods: All equipment used for decontamination should be
disposed of properly (example: using plastic bags).
• PPE for decontamination personnel: The levels of protection will vary with
the level of decontamination and where workers are assigned. For
example, someone in the exclusion zone may need higher protection from
PPE than someone working in the CRZ.

Health and Safety Hazards of Decontamination
Give this one a try later!
Decontamination itself can pose hazards under certain circumstances.
Decontamination methods may be incompatible with hazardous
substances or with the clothing or equipment being decontaminated. Use
the Quick Selection Guide to Chemical Protective Clothing to find the
chemical and physical compatibility of components to ensure maximum
decontamination effectiveness.
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.
