Reporting of any symptom shall be done immediately.
Step 1: Identify Hazards Title (e.g. Physical Hazard, Fire Hazard, and Electrical Hazards).
Step 2: List Hazards Details identified (e.g. Tripping Hazard, Flammable Materials stored, Working in Electrical Cabinets).
Step 3: List Causes of Hazard (e.g. Untidy workplace, Hot work, un-isolated electrical supply).
Step 4: List Consequences of Hazard (e.g. Personnel Injury, Fire, electric shock).
Step 5: Determine Likelihood and Consequences to People, Assets, Environment, and Reputation from attached Risk Assessment Matrix (Page 2) (this should be the most probable outcome without controls and should be listed as 2A, 3D etc.).
Step 6. Calculate the Risk Index using the Qualitative or Semi-Quantitative Risk Assessment Matrix as deemed appropriate. This is a product of Likelihood and Consequence and should be stated Low, Medium, High or Very High).
Step 7. List Existing Controls. (e.g. Tidy Site Policy, Hot Work Permit, Isolation of Electrical Supply).
Step 8. List Safety Critical Activities and Additional Controls that may be deemed necessary to reduce risk level to ALARP.
Step 9: Recalculate Likelihood and Consequences to People, Assets, Environment, and Reputation from attached Risk Assessment Matrix.
Step 10. Recalculate the Risk Index.
Step 11. If residual risk deemed to be High or Very High then risk must be reduced further before proceeding, if risk is medium then note that risk reduction must be planned, monitored and documented, if risk is low then risk is acceptable without required further action.
