Responsible Refrigeration BARNEY RICHARDSON Barney Richardson is the director of South African Refrigeration and Air Conditioning Contractors Association (SARACCA) and sits on various other boards within the HVAC industry, including the South African Qualifications and Certifications Committee for Gas (SAQCC) Gas. THE IMPORTANCE OF RENEWING YOUR REGISTRATION By Barney Richardson The requirement in the Pressure Equipment Regulations that only authorised persons who are registered with SAQCC Gas may work on systems under pressure is very real and a legal requirement in the OHS Act. B ased on the latest registration numbers, the progress in new registrations has been quite good and encouraging. However, the renewal of registrations over the months of February 2019 to March 2020 has been slow and is disappointing. At the end of February there were 405 expired registrations. In the same period there were 535 new first-time registrations and only 337 renewals. Some practitioners use the excuse that they are never asked to show their registration card so why should they bother to do the training and be assessed as competent and to maintain their registration. That is not the point. The reason for registration is to show your client and the end user that you are competent and that the installation or maintenance you do is safe and can be operated with confidence. The client or user of an air conditioning or refrigeration system does not need to ask for a practitioner’s card. The cardholder should show his card with pride and give the client confidence in his work and that of the installation, repair or maintenance being carried out. The motivation of the Pressure Equipment Regulations is to ensure that systems under pressure are installed and maintained by competent persons and no safety issues can occur. The motivation should be that the registered person, be it a Category ‘A’ installer or a Category ‘B’ artisan, be proud that they are qualified to legally work on refrigeration equipment. The training for a first-time practitioner is not onerous (it’s less than a week and only two days for the refresher course). The curriculum and course material and accreditation www.hvacronline.co.za of training providers is being reviewed and upgraded to ensure a level standard of training across the country from all recognised providers. The phase-out of HCFCs is progressing ahead of the scheduled plan from the Department of Environment Forestry and Fisheries (DEFF). The refrigerants in commercial use are slowly switching to HFCs namely R404 and R507 which, if plans are promulgated, will also face phase-out in the years to come. In Europe R404 availability is decreasing with users and contractors being caught short and facing price increases. The refrigerant of choice at present for air conditioners is R410a which is also facing changes. We have seen a move to R32 by some manufacturers and suggestions that R290 will be the next refrigerant of choice. With the changes in refrigerant use and design of air conditioners and self-contained refrigeration units, it makes good sense that practitioners do refresher courses and renew their registrations as and when this becomes necessary. With the changes and the adoption of natural refrigerants, practitioners should keep up-to-date with developments. Training providers are setting themselves up for training in the hydrocarbon refrigerants where special care is required due to working with flammable refrigerants. There is an initiative by the Western Cape Provincial Government to concentrate on R290 as a refrigerant in conjunction with GIZ and the Bavarian state. A facility is in the planning stage to carry out this skill training with the various parties including SAIRAC and SARACCA. RACA RACA Journal I May 2020 63
