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 some discretion, judgement and problem solving

Work requirements include: 

• material to be used
• process required to complete work tasks
• the required size of the units
• number of IGUs required and holding area for completed items

Tools and equipment include: 

• cutting equipment (e.g. saws)
• spacer preparation equipment (appropriate size)
• sieve machine and desiccant equipment
• primary seal equipment
