operating a hand lance

works effectively with others to undertake and complete tack coat spraying operations that meets all of the required outcomes including:

organising work activities to meet all task requirements

communicating clearly and concisely with others to receive and clarify work instructions

using a range of communication techniques and systems such as signage to advise others of work activity and exclusion zone

demonstrates completion of conducting tack coat spraying operations that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:

identifying, reporting and recording hazards and risks

tack coating a minimum of 500m2 of an existing pavement prior to asphalting using the spray bar, completed in a minimum of two separate runs

a minimum of two (2) areas of at least 20m2 to be tack coated using a hand lance


Evidence of Knowledge

The candidate must demonstrate knowledge of conducting tack coat spraying operations through:

applying legislative, organisation and site requirements and procedures for:

site and equipment safety requirements

bituminous surfacing operations

bituminous products

tack coat spraying techniques

project quality requirements

housekeeping

equipment types, characteristics, technical capabilities and limitations

operational and maintenance procedures

site isolation and traffic control responsibilities and authorities

processes for the calculation of material requirements, application rates and travel speed

safety data sheets and materials handling methods

JSAs/JSEA/safe work method statements


Assessment Conditions

An assessor of this unit must satisfy the requirements of the NVR/AQTF or their successors; and Industry regulations for certification and licensing; and,

this unit must be assessed in the context of this sector’s work environment; and,

this unit must be assessed in compliance with relevant legislation/regulation and using policies, procedures, processes and operational manuals directly related to the industry sector for which it is being assessed; and,

assessment may be conducted in conjunction with the assessment of other Units of Competency; and,

assessment must confirm consistent performance can be applied in a range of relevant workplace circumstances; and,

assessors must demonstrate the performance evidence, and knowledge evidence as outlined in this Unit of Competency, and through the minimum years of current* work experience specified below in an Industry sector relevant to the outcomes of the unit; or,

where the assessor does not meet experience requirements a co-assessment or partnership arrangement must exist between the qualified assessor and an Industry subject matter expert. The Industry subject matter expert should hold the unit being assessed (or an equivalent unit) and/or demonstrate equivalence of skills and knowledge at the unit level. An Industry technical expert must also demonstrate skills and knowledge from the minimum years of current work experience specified below in the Industry sector, including time spent in roles related to the unit being assessed; and,

assessor and Industry subject matter expert requirements differ depending on the Australian Qualifications Framework Level (AQF) of the qualification being assessed and/or Industry Sector as follows:

Industry sector

AQF** Level

Required assessor or Industry subject matter expert experience

Drilling, Metalliferous Mining, Coal Mining, Extractive (Quarrying) and Civil Construction

1

1 Year

2

2 Years

Drilling, Coal Mining and Extractive (Quarrying)

3-6

3 Years

Metalliferous Mining and Civil Construction

3-6

5 Years

Other sectors

Where this Unit is being assessed outside of the Resources and Infrastructure Sectors assessor and/or Industry subject matter expert experience should be in-line with industry standards for the sector in which it is being assessed and where no Industry standard is specified should comply with any relevant regulation.

*Assessors can demonstrate current work experience through employment within Industry in a role relevant to the outcomes of the Unit; or, for external assessors this can be demonstrated through exposure to Industry by conducting frequent site assessments across various locations.

**Where a unit is being delivered outside of a Qualification the first numeric character in the Unit code should be considered to indicate the AQF level
