Communicate effectively and work safely with others in the work area

Context of, and specific resources for assessment

The application of competency is to be assessed in the workplace or realistically simulated workplace

Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints

Assessment of essential underpinning knowledge, other than confirmatory questions, will usually be conducted in an off-site context

Assessment is to comply with relevant regulatory and Australian Standards requirements

The following resources should be made available:

workplace location or simulated workplace

materials and equipment relevant to the assessment of lead light and stained glass panels to meet conservation requirements

specifications and work instructions

Method of assessment

Assessment must satisfy the endorsed assessment guidelines of the Furnishing Industry Training Package

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application

Assessment may be applied under project related conditions (real or simulated) and require evidence of process

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances

Assessment may be in conjunction with assessment of other units of competency

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.

OHS requirements

are to be in accordance with Commonwealth, State or Territory legislation and regulations, organisational safety policies and procedures. Requirements may include but not be limited to the use of personal protective equipment and clothing, fire fighting equipment, First Aid equipment, hazard and risk control and elimination of hazardous materials and substances, manual handling including lifting and carrying.

Legislative requirements

are to be in accordance with applicable legislation from all levels of government that affect organisational operation. Requirements may include but not be limited to award and enterprise agreements, industrial relations, Australian Standards, confidentiality and privacy, OHS, the environment, equal opportunity, anti-discrimination, relevant industry codes of practice, duty of care and heritage.

Organisational requirements

may include but not be limited to legal, organisational and site guidelines, policies and procedures relating to own role and responsibility, quality assurance, procedural manuals, quality and continuous improvement processes and standards, OHS, emergency and evacuation, ethical standards, recording and reporting, access and equity principles and practices, equipment use, maintenance and storage, environmental management (waste disposal, recycling and re-use guidelines)

Appropriate personnel

may include but not be limited to clients, architects, engineers construction supervisors, members of heritage committees, government agencies and where appropriate other specialist artisans, such as stonemasons.

Assessment outcomes

may include but is not limited to the requirement to conserve the lead light or stained glass panels, the cost of conservation, recommendations on future tasks

Tools and equipment

may include work benches, ladders and scaffolding, cameras, magnifying glasses, lights and general hand tools

Plans and other documents

may include original architectural plans, historical photographs, charcoal rubbings and sketches

Glass faults

may include but are not limited to cracking, crazing and missing sections, deterioration of glass paint, loose or flaking paint and corroding glass through water or chemical action

Structural faults

may include but are not limited to oxidation and rusting supports, panel frame deterioration, buckled and bowing panels, cracked cames and defective putty, faulty frames or frame settings, broken tie wires and support bars

Environmental effects

may include but is not limited to colour changes, surface etching, lead oxidation

Other problems

may include such aspects as building, wall and roof problems requiring specific remedial action, not directly related to the panel

Conservation requirements

Conservation as defined in the Australia ICOMOS Burra Charter as meaning all of the processes of looking after as place needed to retain cultural significance. It includes maintenance and may include preservation, restoration, reconstruction and adaptation dependent upon specific circumstances. It commonly involves a combination of more than one of these. It also requires that the stained glass conservator respects and understands the requirements of other specialist crafts and the role of other specialist artisans.

Preservation is the process of maintaining the lead light and stained glass panel in its existing state and of retarding deterioration.

Restoration means returning the lead light and stained glass panel to a known earlier state by removing accretions or by reassembling existing components without the introduction of new material.

Reconstruction means returning the lead light and stained glass panel to a known earlier state and is distinguished by the introduction of new materials.
