Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. 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) may also be included.
Operational status may include:
weighbridge indicator being on zero with no load on the platform
platform being clean
area under platform being clean and without accumulation of water or debris
remote indicator, summing indicator and printer indications coinciding with primary indicator(s)
Relevant legislation, codes and regulations may include:
national measurement legislation
relevant codes and regulations pertaining to weighbridge operations
traffic Acts and road transport mass and loading regulations
Australian Dangerous Goods (ADG) codes and regulations pertaining to storing and handling dangerous goods and hazardous materials
relevant state or territory OHS legislation
relevant state or territory environmental protection legislation
relevant Australian and international standards and certification requirements
workplace relations regulations, including anti-discrimination, equal employment opportunity and affirmative action legislation
workers compensation regulations
Faults and discrepancies in weighbridge operation may include:
weighbridge cannot be zeroed with no load on the load receptor
remote indicator, summing indicator or printing device continues to indicate a weight when the primary indicator is outside its weighing range
indications varying, depending on where the vehicle is placed on the platform
indications on the weighbridge not corresponding to another weighbridge in close proximity when weighing the same vehicle
Environmental factors likely to affect weighing accuracy may include:
wind, rain and snow
debris from vehicles being deposited on the platform when moving onto the weighbridge
application of vehicle brakes or air suspension when conducting axle and end-and-end measurements
electrical or radio interference
movement of external fixtures against weighbridge platform.
Vehicles may include:
trucks
cars
articulated road vehicles
heavy machinery
trailers
wagons
Organisational procedures may include:
weighbridge operation manuals
manufacturer specifications and instructions for the operation of weighbridge equipment
Australian and international standards, criteria and certification requirements
codes of practice, including the National Standards for Manual Handling and the industry safety code
relevant regulations, including the ADG code
OHS procedures
quality assurance procedures
Areas of dispute may include:
overloaded vehicle
over-dimension vehicle
uncoupling trailers, etc. to complete weighing
end-and-end measurements
axle measurements
refusal to issue a mass ticket when legislative requirements are not met

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
Competency must be demonstrated in the ability to consistently maintain and operate a weighbridge in accordance with legislative requirements.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessment must confirm the ability to:
prepare a weighbridge for operation
weigh loaded and unloaded vehicles
determine the net weight from gross and tare measurements
complete axle and end-and-end measurements
complete statutory documents
Context of and specific resources for assessment
This unit of competency is to be assessed in the workplace or a simulated workplace environment.
Access may be required to:
weighbridge
computer and relevant software and/or organisation information management system
public weighbridge licence conditions
national measurement legislation
Method of assessment
The following assessment methods are suggested:
questions to assess understanding of relevant procedures, trader obligations and remedial actions
review of weighbridge tickets prepared by the candidate
feedback from supervisors and peers regarding the candidate's ability to conduct weighbridge operations in accordance with legislative and organisational procedures
In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly. Questioning techniques should suit the language and literacy levels of the candidate.
