Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Standards, codes, procedures and/or workplace requirements

Standards, codes, procedures and/or workplace requirements include the latest version of one or more of:

Australian and international standards covering the requirements for the competence of testing and calibration laboratories, laboratory design and construction, physical containment levels and facility types, laboratory safety, and quality and environmental management

national work health and safety (WHS) standards and codes of practice, and national measurement regulations and guidelines

Australian and international standards and guidelines covering specialised forensic tests, accuracy of measurement methods and results, expression of uncertainty and quantifying uncertainty

specific codes, guidelines, procedures and methods, such as the Australian code of good manufacturing practice for medicinal products (GMP), and principles of good laboratory practice (GLP)

workplace documents, such as judicial protocols; SOPs; quality and equipment manuals; data quality procedures; calibration and maintenance schedules; material safety data sheets (MSDS) and safety procedures; material and product specifications; laboratory schedules; workplace recording and reporting procedures; waste minimisation and safe disposal procedures; cleaning, hygiene and personal hygiene requirements; stock records and inventory

forensic sampling procedures (labelling, preparation, storage, transport and disposal)

physical examination techniques and test procedures (validated and authorised)

Samples

Samples include, but are not limited to, one or more of:

fingerprints

firearms and tool marks

ammunition

ballistics

vehicles

documents and handwriting

Physical tests and examination

Physical tests and examinations include, but are not limited to, one or more of:

precise measurement of position, orientation and dimensions (e.g. particle size)

mass, density and specific gravity (e.g. compaction)

thermal tests (e.g. combustion properties)

optical tests (e.g. colour matching)

acoustic tests (e.g. loudness)

electrical tests (e.g. insulation)

magnetic tests (e.g. intrinsic induction)

Validation checks and/or calibration standards

Validation checks and/or calibration standards include, but are not limited to, one or more of:

positive and known positive controls

negative controls (e.g. substrate blanks)

recovery check controls

certified reference materials

Selecting appropriate testing procedures

Selecting appropriate testing procedures includes, but is not limited to, consideration of one or more of:

range, reliability and validity of available techniques and methods

physical characteristics of the evidence

availability of further samples

available resources

time and cost constraints

selection of non-destructive techniques where possible or appropriate

minimisation of sample size for destructive techniques

sequence of forensic techniques

need for possible further analysis by other forensic disciplines

Reviewing laboratory methodology and test results

Reviewing laboratory methodology and test results includes, but is not limited to, one or more of:

assessing the methodology for appropriate application to evidence

assessing chain of custody and sample handling to ensure integrity

assessing testing procedures for compliance with quality system and judicial requirements

evaluating interpretation of test results for validity

Safety procedures

Safety procedures include, but are not limited to, one or more of:

ensuring access to service shut-off points

recognising and observing hazard warnings and safety signs

labelling of samples and hazardous materials

handling and storage of hazardous materials and equipment in accordance with labelling, MSDS and manufacturer instructions

following established manual handling procedures

identifying and reporting operating problems or equipment malfunctions

cleaning and decontaminating equipment and work areas regularly using workplace procedures

using PPE, such as gloves, safety glasses, coveralls and gowns

use of fume hoods, direct extraction of vapours and gases

minimising exposure to radiation ionising, such as lasers, electromagnetic and UV radiation

reporting abnormal emissions, discharges and airborne contaminants, such as noise, light, solids, liquids, water/wastewater, gases, smoke, vapour, fumes, odour and particulates, to appropriate personnel

WHS and environmental management requirements

WHS and environmental management requirements include:

· complying with WHS and environmental management requirements at all times, which may be imposed through state/territory or federal legislation. These requirements must not be compromised at any time

· applying standard precautions relating to the potentially hazardous nature of samples

accessing and applying current industry understanding of infection control issued by the National Health and Medical Research Council (NHMRC) and State and Territory Departments of Health, where relevant

Performance Evidence
