PURPOSE OF THE UNIT STANDARD 
This unit standard will be useful to people who are required to describe and understand the basic methods of controlling ventilation in a work place.

Learners credited with this unit standard are able to:
  • Outline the necessity for ventilating a working place.
  • Describe the methods of controlling ventilation in a working place.
  • Describe the basic effects on workers when exposed to sub standard ventilation conditions. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that learners are already competent in:
  • Communication and Mathematical Literacy at ABET Level 3.

    SPECIFIC OUTCOME 3 
    Describe the basic effects on workers when exposed to sub standard ventilation conditions. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The effects that sub standard ventilation conditions have on the safety; occupational health and productivity of workers are explained. 
    ASSESSMENT CRITERION RANGE 
    Must include: Accumulation of gases, High dust concentrations, abnormal thermal conditions, Oxygen deficiency.
     

    ASSESSMENT CRITERION 2 
    The action to be taken, when ventilation control is not effective, is explained. 

    ASSESSMENT CRITERION 3 
    The importance of taking appropriate action when ventilation control is not effective is explained in terms of consequences to occupational health, safety and production.

    Motivation Re Number of Specific Outcomes:

    Even though there are less than four specific outcomes in this unit standard it represents a whole competency. It is NOT merely a description of tasks, jobs or procedures but it focuses on outcomes of activity. It also has a broad application across a range of contexts as stipulated in the unit standard.

    In addition this unit standard is considered as a milestone of learning in the sector. It is worth recognising in its own right, as it is attributable to and achievable by an individual.

    This unit standard is fit-for-purpose for the sector and the specific outcomes jointly meet all the competence requirements of the title of the standard.

    In addition the unit standard has been integrated to avoid artificial distinctions between activities/processes.

    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.
