1.3. Blocks of glass sheet to be moved are identified and weight is estimated or calculated

1.4. Appropriate mechanical handling equipment is identified

1.5. Risks to self, others, material and equipment are identified arising from the required lifting, load carrying, set down or movement of the glass

1.6. Equipment and controls including emergency stops and guards are identified and checked for safe operation

1.7. Damaged or worn parts are reported to appropriate personnel

1.8. Glass is checked for imperfections and damage prior to movement

2. Plan glass movement

2.1. Locations for glass storage are identified and routes to be followed determined

2.2. Required clearances are compared to available space and adjustments made

2.3. Process for relocating glass is planned including predicting and planning for potential difficulties

2.4. Proposed process is checked against advisory standards and workplace procedures for compliance

3. Relocate glass

3.1. Equipment is operated in accordance with approved advisory standards, manufacturers' instructions, workplace procedures and OH&S requirements

3.2. Planned process and route are followed

3.3. Glass is relocated without damage to material and equipment or injury

3.4. Glass is labelled and stored following workplace procedures ensuring there are no projections

3.5. Relocation is checked to see that it meets work requirements, with any differences reported

4. Complete work

4.1. Waste and scrap material is removed for disposal or recycling as required

4.2. Work area is cleaned and rubbish disposed of as appropriate

4.3. Workplace documentation is completed as required

4.4. Handling equipment is cleaned, maintained and stored according to workplace procedures

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

• collect, organise and understand information related to work orders, basic plans, and safety procedures
• communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with work supervisor, other workers and customers, and the reporting of work outcomes and problems
• plan and organise activities including the preparation and layout of the work area and the obtaining of equipment and materials to avoid any back tracking, workflow interruptions or wastage
• work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity
• use mathematical ideas and techniques to correctly complete measurements, calculate work requirements and assemble required materials
• use pre-checking and inspection techniques to plan work, avoiding re-working and unnecessary effort and plan routes including the avoidance/overcoming of obstacles/hazards
• use the limited workplace technology related to the relocation of block glass sheet by mechanical means

Required knowledge 

• the qualities and characteristics of glass, including the hazards and handling requirements and the behaviour of block glass sheet when lifted and moved
• workflow in relation to the movement of glass by mechanical means
• the principles, requirements and techniques of moving block glass sheet by mechanical means
• workplace safety system requirements related to the moving of block glass by mechanical means
• capabilities, operating processes and procedures of mechanical handling equipment

EVIDENCE GUIDE 

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.

Critical Aspects of Evidence 

• Interpret work order/job instruction and locate and apply relevant information to plan the relocation of glass using mechanical means
• Select and use appropriate equipment and techniques to relocate block glass sheet
• Apply safe handling requirements for equipment, products and materials, include use of personal protective equipment
• Follow work instructions, operating procedures and inspection practices to:

• minimise the risk of injury to self and others
• prevent damage to goods, equipment and products
• maintain required production output and product quality

• As a minimum, demonstrate the ability to:

• identify personal protective safety apparel and safety regulations for overhead lifting
• identify and safely use gantry cranes up to 4.9 swl, including standards and regulations
• identify and use block grabs, slings and chains for lifting blocks or end caps of glass sheets
• calculate the weight of glass
• safely load and secure glass
• relocate blocks and end caps of glass sheets by grabs, slings and chains up to 2 t

• Work effectively with others
• Modify activities to cater for variations in workplace contexts and environment

Resource Implications 

Mechanical glass handling equipment, glass sheet to be relocated, workplace operating procedures and personal protection equipment and an appropriate work area.

Method of Assessment 

Assessment methods must confirm consistency of performance over time and in a range of workplace relevant contexts.

Assessment should be by direct observation of tasks and questioning on underpinning knowledge.

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

Context of Assessment 

Assessment may occur on the job or in a workplace simulated facility with relevant mechanical equipment, block glass sheet, work instructions and deadlines.

RANGE STATEMENT 

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
