Are you using the right heater in your office?

Heaters — 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.

Breeding of unique game requires a balance between conservation and sustainable use

2014-05-20

Game bred for qualities such as unconventional hair colour or horn quality, may on the long term have unexpected consequences for biodiversity and game farming.

This is according to the inaugural lecture of Prof Paul Grobler from the Department of Genetics at the University of the Free State (UFS).

Prof Grobler feels that the consequences of selective breeding should be examined carefully, as there is currently much speculation on the subject without sound scientific information to back it.

“At the moment, colour variation invokes much interest among game farmers and breeders. Unusual colour variants are already available in different game species. These unusual animals usually fetch much higher prices at auctions compared to prices for the ‘normal’ individuals of the species.”

Examples of these unusual variants are springbuck being bred in white, black or copper colours, the black-backed or ‘saddleback’ impala, and the gold-coloured and royal wildebeest.

A black-backed impala was recently sold for R5,7 million.

“Based on genetic theory, good reason exists why these practices need to be monitored, but one should also take care not to make the assumption that selective breeding will inevitably lead to problems,” warns Prof Grobler.

Grobler says that negative characteristics in a species can sometimes unwittingly be expressed during the selection process for a unique colour. “It is seen, for example, in purebred dogs where the breeding of a new race sometimes brings underlying genetic deviations in the species to the front.” He also believes that some of these animals may not be able to adapt to changing environmental conditions.

“However, one should also look at the positive side: because of the good demand for game, including unusual variants, there is much more game in South Africa today than in many decades. Balance should be found between the aims of conservation and the sustainable utilisation of game.”

Research at the UFS’s Department of Genetics is now trying to establish the genetic effects of intensive game breeding and predict the impact on biodiversity.
