Fire
Fire facts: Assuming stable fuel, heat, and oxygen levels, a typical house fire will double in size every minute.


There are certain incidents that you cannot prevent from happening in life. However, in case the worst happens, you can always be well-prepared to take the right action. Fire outbreaks are a case in point. 

Certain rules apply to mitigate risks that may cause bodily harm. As a student, the University of the Free State is committed to ensuring that your well-being is taken care of.

In case of a fire, here are a few tips to remember:
1. Know your emergency evacuation plan
2. Know the fire brigade’s number 
3. Trust your Protection Services, notify them ASAP
4. Never waste time. Get up and get out
5. Wait to be accounted for at designated assembly point
6. Go low and never breathe in smoke, all smoke is toxic 
7. Close all windows and doors in case of a fire
8. Alert everyone in the building through the alarm system
9. Know your emergency exists and use them
10. Never try to be a hero, save yourself first

Once you are safe and sound, refrain from posting on social media before Emergency Services arrive. You are urged to obey these safety rules in all buildings and residences on campus.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

17 September 2013

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
