In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.

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 standard is aimed at people who work or intend to work within a large process operation in the chemical or similar industry, and seek recognition for skills essential for operating within a chemical system.

Those learners who acquire the outcomes of this standard will know about and be able to shut down the system to s specified state, pertaining to the chemical industry.

For the purpose of this qualification the following is understood as a system:

Equipment operated in combination to achieve a desired result in a chemical or related process operation

Operating a system included the integrated operation of the equipment that makes up the system

The qualifying learner is able to:

Establish shut down conditions for the system

Shut down the system to a specified state

Communicate information concerning system shut down

Correct abnormal system shut down conditions

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING

Learners accessing this unit standard will have demonstrated competence against the unit standards or the equivalent; - Establish equipment start up conditions, Start up equipment, Shut down equipment, Contribute to maintenance of equipment

Learners working towards the full qualification will have demonstrated competence against the unit standards in the National Certificate in Chemical Equipment Operations - NQF Level 2 or equivalent

UNIT STANDARD RANGE

Standard operating procedures will include site operating instructions, standard operating procedures, orders, guidelines, policies, procedures and systems

Check lists may include visual inspection and equipment integrity tests

Types of shutdowns include routine, emergency and product change

Action may include trips of equipment, open and shut valves and repeat start up checks and tests

Operating conditions may include temperature, flows, pressures, line obstruction and noise levels

Communications may include fact to face, telephone, radio and written

Records may include blind lists, logs, trip sheets and line-up drawings

Abnormalities may include electrical, line obstruction, permit conditions not met, leaks, mechanical, incompleteness, incorrect line up and pump cavitations

Remedial action may include valve isolation, line clearance, draining, purging and cleaning

This unit standard relates to all the equipment in level 2 that has been interconnected via an automated control system, to form a stand-alone system. For example systems may include, distillation towers, absorbers, molecular sieves, extractor column, fluidised reactor, fixed bed reactor, batch reactor, regenerators, pressure vessels, kettle heat exchangers, furnace fired / natural draught, flares, fire / water tube boilers, refrigeration units, soot blowers, evaporators, steam turbines, de super heaters, absorber, re-boilers, water softening systems (to include de-ionisation, de-mineralisation and ion exchange), leaching equipment, liquid extraction equipment, separator (to include solids, liquids, and gasses), ejectors, extruders, scrubbers, material forming preparation systems and materials handling systems. Other systems may be included as they relate to the learners' specific working environment.

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.
