Range Statement
The Range Statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.ContextThis unit will be completed as a specialist unit (eg by plant technicians) requiring technical knowledge. The aim of this competency unit is to apply a methodical examination of the system and its elements to identify hazards and the states or conditions where there may be loss of control of the hazard and the resultant consequences The results of the hazard analysis should be expressed clearly and concisely, and include where possible tables and diagrams. Team members would contribute their understanding of the process and particularly the operational aspects, and then carry out whatever tasks are assigned to them by the analysis team.While this competency aims to enable a person to identify hazards and assess risk through a systematic approach, more than 80% of recommendations can be operability problems and are not, of themselves, hazards. Although hazard identification should be the main focus, operability problems should be identified to the extent that they have the potential to lead to a breakdown in hazard controls resulting in a health, safety or environmental violation or have a negative impact on profitability.The degree of depth of a checklist should be dependent on the knowledge of the system at the time the study is carried out. This technique can therefore be applied at any stage of the project/process lifecycle. Screening for deviations includes accessing internal and external data that may provide information about previous incidents or warnings of incidents. Sources of such information may include:internal hazard and incidents reports, maintenance records, audit reportsreports from similar plants, factories, industry bodies, regulators, journals etc of actual incidents or reports that have relevance to the situation being analysed. Examples of risk assessment tools may range from relatively simple to more complex HAZOP analyses and other methodologies requiring similar competency.ProceduresAll operations are performed in accordance with procedures.Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards. HazardsTypical hazards include:handling chemicals and hazardous materials chemical and or hazardous materials spillagegases and liquids under pressuremoving machinerymaterials handling working at heights, in restricted or confined spaces, or environments subjected to heat, noise, dusts or vapoursfire and explosion. ProblemsTypical process and product problems may include:incidents with a potential for injuryfires, explosionschemical spillsbomb scares.Process ParametersSpecific process parameters (primary key words) relevant to the system may include:flowtemperaturepressurereliefinstrumentationsamplingadditionsafetyreactionreduce (grind, crush)absorbisolateventstart-upcompositionphaselevelcorrosionerosionservicesutilitiesmaintenance/maintaininsertingpurgingcontaminationseparate (settle, filter, centrifuge)mixdrainshutdown.
