RISK ASSESSMENT MATRIX AND ITS APPLICATION IN DECISION MAKING




Using the Risk Assessment Matrix.
When assessing a risk for the first time you should assume there are no controls already in place.  The subsequent two assessments are completed with 
1) those controls already in place and 
2) with any additional controls needed to reduce the risk further.  

 The assessor should assign values for the identified 
‘likelihood’ of occurrence (A) and 
the severity of the ‘Impact’ (B).  

 By multiplying ‘A’ and ‘B’ together you get the rating score, which gives an indication of how important the risk is.  The thick black line is the “line of tolerance”.  Those risks that are plotted above the line (score 10 – 25) are “out of tolerance” and should be referred to CRMG for further consideration.

Green = Low risk, Amber 9 = Medium risk, Amber 10 –12 high risk, Red = High risk

Likelihood of Occurrence (A)
Severity of Impact (B)
1-   Very unlikely    (hasn’t occurred before)
1 -   Insignificant   (have no effect)
2 -  Slight                 (rarely occurs)
2 -   Minor               (little effect)
3 -  Feasible            (possible, but not                                         common)
3 -   Significant     (may pose a problem)
4 -  Likely                 (has before, will again)
4 -   Major              (Will pose a problem)
5 -  Very Likely       (occurs frequently)
5 -   Critical            (Immediate action required)

Exercise on risk assessment


Part 1—What are the risks associated with working in a flower farm/construction site/soap making factory

                                                                                                                                                           

                                                                                                                                                           

                                                                                                                                                           

                                                                                                                                                           

Part 2—Evaluate the likelihood and potential impact of the risks:

Risks
Probability?
(High, Medium, Low)
Potential Impact? (High, Medium, Low)
Overall Significance of Risk
(High, Medium, Low)
1)



2)



3)



4)



5)





Which risks should you focus your resources on?

SUNFLOWERS THE CLEANERS OF THE ENVIRONMENT

Ever since the Chernobyl disaster and the Fukushima Daichi disaster , scientists have been studying the best ways to reclaim the lands that are inhabitable and are regarded wastelands that are too toxic for human habitation. In comes SUNFLOWER , The doctor as it is called in West Africa . After the Hiroshima , Fukushima, and Chernobyl nuclear disasters, fields of sunflowers were planted across the affected landscapes to help absorb toxic metals and radiation from the soil. New research now suggests that sunflowers ( Helianthus )  might be as good for the environment as they are pretty to look at. Sunflowers are what environmental scientists call  hyperaccumulators –  plants that have the ability to take up high concentrations of toxic materials in their tissues. Like all land-based plants, flowers have root systems that evolved as extremely efficient mechanisms for pulling nutrients, water, and minerals out of the ground, among them: zinc, copper, and o...

EIA ASSIGNMENT

EIA ASSIGNMENT An Investor wants to put up an Industrial Plant for the manufacture of paper and its derivatives for both local and external market. The Investor intends to establish the paper manufacturing mill in relatively wet and forested upper parts of Laikipia District in the slopes of Mt. Kenya. A part from the paper mill, the Investor will also provide infrastructure and social amenities in the region. In view of the socio-economic and bio-physical environmental implications that may result due to the proposal, there has been public debate particularly on the loss of habitat/biodiversity and competition for scarce water resources in the region. Assuming your consultancy firm has won a contract to undertake Environmental Impact Assessment (EIA) study on this proposed project:  Discuss the logical steps in the EIA process that your study team is likely to follow in order to achieve the task assigned to you. Justify the formation of the Interdisciplinary Team for this ...

EGERTON UNIVERSITY ATTACHMENT REPORT

ACKNOWLEDGMENT I would like to dedicate this work to all stake holders who have given me support. I would like to thank entire Egerton University, especially to the department of Environmental Science. Special gratitude goes my field attachment supervisors at K.M.F.R.I kisumu especially Mr. E.J. Odada and Dr. Lewis Sitoki for availing their time to ensure my success during the attachment period ABSTRACT The field/industrial attachment period is a critical period for students and it seeks to help them get exposed and familiarize themselves with the working environment in their areas of specialization, the attachment period also helps one to get to understand the application of all that which he has learnt in class and thus equips him/her with the ability to apply this knowledge. KMFRI Kisumu is a research Centre of KMFRI and its main role is to undertake research on aquatic resources in inland waters. Main areas covered include Ecos...
