COMPETENCY LEVELS AND REGISTRATION OF PERSONNEL

By Grant Laidlaw
To address this , we must refer to the requirements as laid out in SANS 10147 as well as SAQCC gas requirements .
Dawie asks : Grant , could you assist on two issues , firstly what is the competency level requirement for air conditioning and refrigeration technicians , and secondly how does this align with the registration of authorised refrigeration personnel ? Thanks .

Hi Dawie , these aforementioned aspects must also remember SANS standards , the OHS act , and pressure vessel regulation that all represent legal requirements . With regards to staff competence as per SANS10147 : All personnel involved in the operation and maintenance of refrigeration installations shall have been trained on the functioning of the installation to ensure that they are fully conversant with the equipment concerned .

In the case of a refrigeration plant erected on site , the personnel that are to be involved in the operation and maintenance shall be present during the erection , testing , charging of refrigerant , and adjustment of the plant . Personnel who , in the course of their duties , have to enter refrigerated spaces , shall be trained in the use of all safety devices , procedures and health hazards and shall be qualified at the appropriate level of competency .
Control and safety devices that shall not be operated by unauthorised persons , shall be safeguarded against deliberate or accidental actuation .
The operation and maintenance of existing refrigeration plants shall comply with the requirements given , and any conversions or modifications to such plants shall be carried out by a level B or C competent person .
Dawe , when considering the alignment of a SAQCC authorised gas practitioner registration through SARACCA and SANS , we find descriptions with regards to the categories A , B and C as follows :
( See the SARACCA website for full details on this )
