Group Exercise 1, Step 1

Using your risk assessment scenarios A, B, or C, identify four different risk mitigation measures

Four for safety Two for security

Use a post-it note for each mitigation measure you identify Report your answers to the class in 15 min


Biorisk Mitigation

How would you categorize these mitigation measures? Take 10 min to report your answers to the class

Mitigation Control Measures

Engineering Controls: Physical changes to work stations, equipment, materials, production facilities, or any other relevant aspect of the work environment that reduce or prevent exposure to hazards

Administrative Controls: Policies, standards and guidelines used to control risks

Practices and Procedures: Processes and activities that have been shown in practice to be effective in reducing risks

Personal Protective Equipment: Devices worn by the worker to protect against hazards in the laboratory

Considering these mitigation control measures:

Take 10 min to:

Identify their advantages and disadvantages

Report your findings to the class





(PPE)

Advantages/Disadvantages

Control Measure Advantages Disadvantages

Engineering

Efficient, eliminates hazard

Cost, complexity

Administrative

Authority approach

Indirect approach, primarily addresses the human factor

Practices & Procedures

SOP based (standardized approach)

Training and supervision requirements

PPE

Ease of use, relative cost

Does not eliminate hazard, PPE fails exposure happens, uncomfortable, limits ability


Biorisk Mitigation

Considering these mitigation control measures:

Prioritize the four types of controls from the perspective of effectiveness

Record your findings on post-it notes

Report your findings to the class

Most Effective

Least Effective

Elimination or Substitution Engineering Controls Administrative Controls Practices and Procedures Personal Protective Equipment

Control methods at the top of the list are in general more effective and protective than those at the bottom.

Hierarchy of Controls (HOC)

Presenter

Presentation Notes

A Biosafety level is a combination of all controls. We usually use a combination of all controls Such combination varies between one location and another (country)

Group Exercise 2

In your groups, using risk scenarios A, B, or C, reassess the risks by implementing the mitigation measures identified in Exercise 1

Biosafety Biosecurity

Use the worksheets to do the new assessments, and then ask a facilitator to enter the new data into BioRAM Lite Take 50 min to document the new results on your charts Report to the class on risk reduction and risk mitigation effectiveness

Mitigation measures most affect which side of the risk assessment equation?

Presenter

Presentation Notes

Answer is: Likelihood


Biorisk Mitigation

Substitution (using different materials) affects what side of the

risk assessment equation?

Presenter

Presentation Notes

Answer is: Consequences


Biorisk Mitigation

of 27


Elimination (not doing the intended work)

does what to the risk ?

Presenter

Presentation Notes

Answer is: Removes the risk


Biorisk Mitigation

of 27


Implementing Mitigation Measures

Ideally, you should first consider elimination or substitution A combination of control measures should be used based on their effectiveness and your ability to implement them

'acceptable risk'

The "Wow" Effect

A robust methodological approach to risk mitigation gives you the ability to:

• Justify decisions

• Evaluate the impact of certain risk mitigation decisions

• Compare the cost effectiveness of various risk mitigation decisions

Summary I

BioRAM The full BioRAM models are available on the following website: http://www.biosecurity.sandia.gov/BioRAM/

BioRAM Lite Training version; it is very simplified and has many limitations It should not be used to make actual lab safety/security decisions Also available on the above link

Summary II

Four categories of mitigation control measures Engineering Controls Administrative Controls Practices and Procedures Personal Protective Equipment

Implementing mitigation controls Should first consider elimination or substitution A combination of control measures should be used based on their effectiveness and your ability to implement them Should be based on the results of the risk assessment, and should give a “wow” effect
