Activity What are the Hazards? What is the Risk? How are you going to Control the Hazard and minimise the risk of injury? Who is going to Monitor and 
  (What has the potential to cause injury?) (From Risk Calculator - see below) A HAZARD MAY REQUIRE THE USE OF ONE OR MORE CONTROL MEASURES - CROSS OUT/ DELETE CONTROL MEASURES NOT USED Review it and How?
      1.  Identify underground services.  Establish a 1.5M Exclusion Zone around the Name

HOW TO USE THIS RISK TABLE RISK RATING CALCULATOR Likelihood Risk Rating Prioritisation
    Consequence Very likely Could happen anytime Likely Could happen sometimes Unlikely Could happen, but only rarely Very Unlikely Could happen, but probably never will 1 or 2 Action to rectify
Step 1:  Identify potential hazards. What injury/damage could it cause?   must be done
Step 2:  Decide what the possible Consequence could be Death or permanent disability 1 1 2 3   immediately
Step 3:  Decide How Likely? It is to happen Long term illness or serious injury 1 2 3 4 3, 4 or 5 Consider
Step 4:  Line up your choices in the table to get a number Medical attention & several days off work 2 3 4 5   control measure
Step 5:  Use the Priority table (far right side) to guide your next steps First aid needed 3 4 5 6   as necessary
