Unit of Competency PMC552002C - Operate equipment to blend_mix materials
Description This unit of competency covers the selection and blending/mixing of materials using blending/mixing equipment. It involves loading and unloading equipment, monitoring the process, maintaining a safe work environment and conducting routine maintenance.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit of competency applies to operators who are responsible for selecting and blending a variety of materials to produce a variety of products. This competency does NOT cover concrete mixing nor asphalt mixing for which the specific competencies PMC552060C Batch mix concrete and PMC552065B Prepare asphalt should be used.If manual handling forms part of this job then regulatory obligations will require competency in PMBHAN103C Shift materials safely by hand. This competency is typically performed by operators working either independently or as part of a work team. At all times they would be liaising and cooperating with other members of the team.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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.

Overview of assessment

The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

It is essential that the equipment be understood and that the importance of critical material properties, settings and readings is known.

Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency.

Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action.

Consistent performance should be demonstrated. In particular look to see that:

hazards are identified and controlled

blend/mix properties are kept within limits

quality is monitored to minimise wastage

process measurements/observations are continually made

all OHS requirements are followed

problems are anticipated and appropriate action is taken (i.e. problem fixed or reported).

Context of and specific resources for assessment

Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations.

Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.

Simulation or case studies/scenarios may be required to allow for timely assessment of parts of this unit of competency. Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions.

Method of assessment

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units.

It may also be appropriate to assess this unit in conjunction with:

MSAC112003A Undertake manual handling.

Individual enterprises may choose to add prerequisites and co-requisites relevant to their processes.

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assignment, checklist) and due date here

Assessment task 1: [title]      Due date:

(add new lines for each of the assessment tasks)

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Required skills include:

recognising conditions which will lead to out of specification product

implementing the enterprise's procedures within time constraints and in a manner relevant to the correct use of the equipment

conveying information relevant to the operation clearly and effectively

maintaining appropriate levels of quality assurance

reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes:

hazards associated with the process

application of the hierarchy of control in controlling the hazards

selection, use and maintenance of relevant personal protective equipment (PPE)

material handling requirements

principles of blending/mixing these products

impact of variations in materials on final product

impact of blending/mixing on final product

impact of variations in product specification of the blending/mixing process

properties of the mix

equipment limitations and impact on blending/mixing efficiency and effectiveness

enterprise production schedules

underlying causes of faults such as precipitated by:

material

equipment

blending/mixing time/technique

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.

Procedures

All operations are performed in accordance with standard procedures and work instructions.

Equipment and unit operations

All such items of equipment and unit operations must form part of a discrete blending/mixing system. These may include:

pumps (lubrication and cooling pumps)

utilities and services

heat exchangers (intercoolers)

vibration monitoring

other equipment integral to the operation of the compressor system

Typical problems

Typical problems may include:

equipment malfunction

material handling such as equipment failure and blockages

material property variation

blend/mix tolerance

uniform dispersion of minor ingredients/additives

blending/mixing to special requirements/colour

mixing sequence

matching mixes produced with production requirements

monitoring and adjusting process conditions

recognising and acting on potential and actual problems

quality problems including customer requirements

Occupational health and safety (OHS)

All operations are subject to stringent OHS requirements and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and OHS requirements, the OHS requirements take precedence

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
