This unit standard does not replace any other unit standard and is not replaced by any other unit standard.

PURPOSE OF THE UNIT STANDARD

This unit standard will be useful for people who have to clear hot material blockages in cement and lime manufacturing applications. This unit standard was developed due to the highly dangerous nature of this task and the fact that a number of co-ordinating activities have to be performed in the process of clearing such blockages. Persons credited with this unit standard are able to

identify/detect blockages;

assess the potential hazard;

prepare to clear blockages;

clear blockages;

conduct post-clearing activities and

demonstrate knowledge of blockage clearing methods and the application of safe work procedures.

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING

The credit calculation is based on the assumption that learners are already competent in terms of the following outcomes or areas of learning when starting to learn towards this unit standard:

Appropriate knowledge and competence relating to manufacturing process, equipment and plant

Appropriate knowledge and competence relating to instrumentation (temperature, pressure, amperage)

UNIT STANDARD RANGE

The following scope and context applies to the whole unit standard:

All areas of the process where material reaches substantially high temperatures in the range of 100?C to 10000C plus.

Cold material blockage clearing will be dealt with under normal plant operating unit standards.

Specific range statements are provided in the body of the unit standard where they apply to particular specific outcomes or assessment criteria

UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS

1. Anyone assessing a learner against this unit standard must be registered as an assessor with the relevant ETQA.
2. Any institution offering learning that will enable achievement of this unit standard must be accredited as a provider through the relevant ETQA by SAQA.
3. Moderation of assessment will be overseen by the relevant ETQA according to the moderation guidelines in the relevant qualification and the agreed ETQA procedures.

UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE

Essential embedded knowledge will be assessed through assessment of the specific outcomes in terms of the stipulated assessment criteria. Without knowledge of the listed embedded knowledge, candidates are unlikely to achieve all the specific outcomes to the standards described in the assessment criteria.. This means that for the most part, the possession or lack of the knowledge can be directly inferred from the quality of the candidate`s performance. Where direct assessment of knowledge is required, assessment criteria have been included in the body of the unit standard.

PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD:

This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
