Specifies different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Range is restricted to essential operating conditions and any other variables essential to the work environment.

Unit context includes: 

• WHS requirements, including legislation, building codes, material safety management systems, hazardous and dangerous goods codes, and local safe operating procedures or equivalent
• work is carried out in accordance with legislative obligations, environmental legislation, relevant health regulations, manual handling procedures and organisation insurance requirements
• work requires individuals to demonstrate discretion and apply judgement and problem solving to complex issues

Appropriate personnel include: 

• clients
• architects
• engineers
• construction supervisors
• members of heritage committees
• government agencies
• other specialist artisans, such as stonemasons, where appropriate

Assessment outcomes include: 

• the requirement to conserve the leadlight or stained glass panels
• the cost of conservation
• recommendations on future tasks

Tools and equipment include: 

• work benches
• ladders and scaffolding
• cameras
• magnifying glasses
• lights
• general hand tools

Plans and other documents include: 

• original architectural plans
• original drawings, cartoons and cut lines for glass panel
• historical documentation and photographs
• charcoal rubbings
• sketches

Glass faults include: 

• cracking
• crazing and missing sections
• deterioration of glass paint
• loose or flaking paint
• corroding glass through water or chemical action

Structural faults include: 

• 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 include: 

• colour changes
• surface etching
• lead oxidation

Other problems include: 

• building, wall and roof problems requiring specific remedial action, not directly related to the panel

Conservation includes: 

• advice in the Australia International Council on Monuments and Sites (ICOMOS) Burra Charter as meaning all of the processes of looking after a place needed to retain cultural significance
• preservation, restoration, reconstruction and adaptation dependent upon specific circumstances (or a combination of more than one of these) respecting and understanding the requirements of other specialist crafts and the role of other specialist artisans

Preservation includes: 

• maintaining the leadlight and stained glass panel in its existing state and of retarding deterioration

Restoration includes: 

• returning the leadlight and stained glass panel to a known earlier state by removing accretions or by re-assembling existing components without the introduction of new material

Reconstruction includes: 

• returning the leadlight and stained glass panel to a known earlier state and is distinguished by the introduction of new materials

Condition report includes: 

• detailing the extent of the problems
• recommended solutions, including methodologies
• photographic evidence of current condition and location
• legislative requirements related to heritage leadlight and stained glass and their effect on the recommendations and probable costing

Personal protective equipment includes: 

• that prescribed under legislation, regulation and enterprise policies and practices:

• gauntlets
• gloves
• safety glasses
• hard hats
• safety footwear
• aprons and overalls

Information and procedures include:
