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 into common types and identifying them by surveying all the different areas of the site.
Hazard identification by work analysis – Work that is not done on a static site is probably better analysed by first identifying the different occupations involved and the work people carry out, then the hazards they face doing that work. This method is better suited for those work activities where there is a considerable degree of scope for the worker to decide how the task is carried out, e.g. tradespeople. This analysis would be applicable for work in construction, forestry operations and similar work where people tend to work in small autonomous groups with minimal supervision. A major problem with this approach is the hazards that are not part of someone’s work will not be identified, e.g. storage areas for waste chemicals.
Hazard identification by process – A more technical approach to hazard identification is to identify the processes involved on a worksite and go through each process step-by-step, identifying the hazards at each step of the process. With plant of any complexity, the time taken to identify individual potential hazards can be larger than the time taken to quantify the risk of the hazards.
Task 2 (P1.4)
Hazards in a workplace are controlled by a combination of “local controls” specific to a hazard, and “management controls” for ensuring that these are implemented and remain active. The mechanism for the control of a hazard may not necessarily be a physical
