Pass Criteria. Task 1 (P1.3) Three effective ways to systematically identify existing hazards are: 1. By examining specific areas of the worksite and the activities carried on in them. 2. By analysing different occupations and their tasks. 3. By analysing the total process used to convert raw materials into final product for sale. Hazard identification by area – Static worksites such as Engineerig Factories are well suited to a hazard identification method involving grouping hazards
