DEFINITION OF TERMS

  • Die – A former used to give the required shape to the product and which is used under pressure. Dies are typically used in the extrusion, injection, blow moulding and general rubber sectors. Dies used which are not subject to pressure are referred to as ‘moulds’ in this Training Package.
  • PPE Personal Protective Equipment – the last line of defense against workplace hazards – includes things like safety boots, gloves, goggles, ear muffs.
  • Routine Problems –  To ‘rectify routine problems’ means ‘apply known solutions to a limited range of predictable problems’.
  • OH & S – Occupational health and safety
  • Composites – Products consisting of a polymer matrix and a continuous layered reinforcing media. The reinforcing media include fiber, filament and cloth. The product is generally hand or machine fabricated.
  • Calibration – Instruments and other measuring equipment are calibrated to make sure the readings they yield are correct.
    To calibrate an instrument/item of equipment is a high level unit of competency.
    To check the calibration of an instrument/item of equipment is a routine part of using it and may be as simple as checking the date the calibration certificate expires.
  • Engineering Control – A subset of the hierarchy of control.
  • Hierarchy of Control – The preferred order of risk control measures from most to least preferred, that is:
    • elimination
    • substitution
    • engineering controls
    • administrative controls
    • personal protective equipment.
  • Integral Equipment which forms part of the operation of a main item of equipment is regarded as ‘integral’ to that main item. Examples include feed hoppers (and even blending feed hoppers) and heating and cooling devices.
    Typically equipment will be regarded as being ‘integral’ to the main item if:

    • it is close/attached to the main item
    • it has simultaneous operation with the main item
    • it does not require significant additional knowledge or skills.
      Equipment is not integral if it has independent operation of its own.
