This unit describes the skills and knowledge required to assist with monitoring a range of physical agents and conditions relevant to work health and safety (WHS).

It applies to individuals working in a broad range of WHS roles across all industries who assist with using a range of measuring devices to collect, interpret, evaluate and report on workplace information and data in relation to physical agents and conditions.

It does not extend to hazard identification, risk assessment or developing control measures based on the outcomes of monitoring, which are covered in BSBWHS404 Contribute to WHS hazard identification, risk assessment and risk control.


  1. Assist with selecting measuring devices
  2. Assist with preparations to collect workplace information and data
  3. Assist with collecting workplace information and data
  4. Assist with documenting and evaluating results of monitoring

Upon successful completion of this unit, you will:

  • identifying regulatory requirements and standards that apply to monitoring of physical agents and/or conditions relevant to work health and safety (WHS)
  • identifying the context of measurements to be undertaken including:
    • which physical agents and/or conditions will be measured and their characteristics
    • where the measurements will be taken
    • area or space available
    • movements of people and equipment, tasks or activities being undertaken, number of persons occupying area and other factors that may impact on the sampling or data-collection processes
    • physical features of equipment, such as emitting sources
  • preparing for and collecting workplace WHS data and information including:
    • selecting and calibrating appropriate equipment and selecting appropriate scale
    • defining a sampling process and plan
    • performing tests
    • correct preparation, use, maintenance, cleaning storage and if required disposal of equipment
  • consultation and communication with individuals and parties about the requirements, purpose and nature of the monitoring
  • interpreting and evaluating results of monitoring including calculations using appropriate units of measurement, logarithmic scales, decimals and order of magnitude relevant to making and interpreting measurements and measurement error
  • preparing and presenting clear and logical reports that are appropriate to purpose of report and the target audience
  • keeping records that meet regulatory requirements
  • seek expert advice, support and equipment as required
  • ensure own safety during monitoring process

Demonstrate knowledge of:

  • typical physical agents and/or conditions relevant to WHS including:
    • biological agents, such as insects, mites and bacteria
    • electricity
    • fibres, dusts and particulates
    • fumes, mists, gases and vapours
    • heat and humidity
    • light
    • noise
    • radiation, including ionising, non-ionising and laser
    • vibration
  • aspects of WHS Acts, regulations, codes of practice and standards that are relevant to measuring physical agents and/or conditions and how they apply to the organisation
  • the mode of action of common physical, biological and chemical agents on the body and how they produce discomfort or harm
  • the characteristics, mode of action and units of measurement for major hazard types
  • environmental conditions that impact on measurements
  • types of measuring and monitoring equipment and techniques for correct and safe use including limitations on use and output, calibration, adjustment, maintenance and any in-built alarms

Nominal Hours: 60
