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 
Persons who have been found competent in this unit standard will be able to sample air by means of a real time dust monitor to determine the concentration of aerosols and recommend appropriate remedial action. This competency includes all the pre-, inter- and post-activities and explanations associated with the sampling procedure.

    The real time dust monitor is examined, calibrated and zeroed. 

    ASSESSMENT CRITERION 2 
    The specified instruments are handled safely. 

    ASSESSMENT CRITERION 3 
    The conditions under which measurements are made are checked and the impact of adverse conditions on readings is explained. 

    ASSESSMENT CRITERION 4 
    The correct measuring position is selected and the importance thereof, explained. 

    ASSESSMENT CRITERION 5 
    The importance of obtaining permission to enter the working place is explained and obtained. 

    ASSESSMENT CRITERION 6 
    The position where sampling is to take place is examined for hazards and risks and these are dealt with where applicable. 

    ASSESSMENT CRITERION 7 
    Instruments and accessories, including personal protective equipment, are obtained, inspected and tested for functionality prior to use. 

    SPECIFIC OUTCOME 3

    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.
