An enormous part of worker safety is the prevention of hazardous situations at the mine site – especially those areas where risks are highest. There is always room to improve that level of safety, and behind that is understanding more about risk mitigation. To create a fire there must be three elements: oxygen, heat and fuel (also known as “the…
