Embrace the warmth of safety: Stay cozy with approved quartz heaters such as the Goldair GHQ-100G, keeping our campus secure and snug.

As winter approaches, the University of the Free State (UFS) is expecting increased heater usage. The Department of University Estates is proactively addressing this surge in energy demand caused by colder weather to safeguard our campuses and help mitigate the risk of loadshedding, ensuring uninterrupted operations for our staff and students.

By addressing the surge in energy demand caused by colder weather and promoting energy-efficient practices, UFS aims to play its part in alleviating the strain on the power system and contributing to national efforts to mitigate loadshedding.

With South Africa enjoying a recent break from loadshedding, Nicolaas Esterhuysen, Director of Engineering Services, stresses the importance of wise electricity usage to prevent outages and maintain safety. “During this uninterrupted power supply, it’s crucial to be mindful of our electricity usage, especially regarding heating in winter,” Esterhuysen emphasises. “By adopting energy-efficient practices, we contribute to the university’s energy-efficiency goals and create a safer environment."

In line with promoting energy efficiency, the Office for Occupational Health and Safety (OHS) is rolling out a comprehensive campaign to remove unauthorised heaters, minimising fire risks in residential and office areas.

Thato Block, Deputy Director of OHS, explains: “With the structural fire season approaching, UFS is prioritising campus safety. As colder weather looms, heaters and other warming devices will be in high demand, prompting preemptive action. OHS and the Electrical workshop will commence removing unauthorised heaters from residences and offices starting May 2024.”

Guidelines for heater usage

To ensure compliance and safety, UFS has established specific guidelines for electrical heater usage on its premises. The Standard Operating Procedure (SOP) outlines permissible and prohibited heater types, along with safety measures.

According to the SOP, only quartz heaters meeting specific criteria, such as the Goldair GHQ-100G model, are permitted on campus. These heaters are designated for offices without air conditioning, prioritising energy efficiency and safety. Furthermore, heaters are not permitted in residences due to the presence of centralised heating systems.

Prohibited models like bar, fan and oil heaters are strictly banned due to their high energy consumption and fire risks. Any unauthorised heaters found on campus will be confiscated to prevent electrical circuit overload and ensure emergency power system reliability.

In addition to regulating heater types, the UFS has implemented a stringent purchasing procedure overseen by the Department of University Estates Electrical Engineers. Approval is required before requisitioning heaters, with only quartz heaters meeting purchase criteria. This proactive approach aims to effectively manage electricity consumption, especially during peak demand periods in winter.

Safety precautions

The UFS community is reminded to exercise caution when using heaters, including maintaining a clutter-free environment around the device, and avoiding covering it. It’s also important to ensure adequate distance between the heater and flammable materials, switch off heaters when unattended, and disconnect them from power sources during prolonged periods of non-use.

Commitment to campus safety

The UFS remains committed to prioritising the safety and well-being of its community. Through proactive measures and fostering safety awareness, the university aims to create a secure environment conducive to teaching and learning throughout the year.

UFS researchers are producing various flavour and fragrance compounds
2015-05-27

 

The minty-fresh smell after brushing your teeth, the buttery flavour on your popcorn and your vanilla-scented candles - these are mostly flavour and fragrance compounds produced synthetically in a laboratory and the result of many decades of research.

This research, in the end, is what will be important to reproduce these fragrances synthetically for use in the food and cosmetic industries.

Prof Martie Smit, Academic Head of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, and her colleague Dr Dirk Opperman, currently have a team of postgraduate students working on the production of various flavour and fragrance compounds from cheap and abundantly available natural raw materials. 

Prof Smit explains that most of the flavours and fragrances that we smell every day, originally come from natural compounds produced mainly by plants.

“However, because these compounds are often produced in very low concentrations by plants, many of these compounds are today replaced with synthetically-manufactured versions. In recent times, there is an increasing negative view among consumers of such synthetic flavour and fragrance compounds.”

On the other hand, aroma chemicals produced by biotechnological methods, are defined as natural according to European Union and Food and Drug Administration (USA) legal definitions, provided that the raw materials used are of natural origin.  Additionally, the environmental impact and carbon footprint associated with biotech-produced aroma chemicals are often also smaller than those associated with synthetically-produced compounds or those extracted by traditional methods from agricultural sources.

During the last four years, the team investigated processes for rose fragrance, vanilla flavour, mint and spearmint flavours, as well as butter flavour. They are greatly encouraged by the fact that one of these processes is currently being commercialised by a small South African natural aroma chemicals company. Their research is funded by the Department of Science and Technology and the National Research Foundation through the South African Biocatalysis Initiative, the DST-NRF Centre of Excellence in Catalysis and the Technology Innovation Agency, while the UFS has also made a significant investment in this research.
