Suspected illegal processing of minerals in a settlement close to Lilian Ngoyi Street in Johannesburg, has killed nine people, injuring another 48 lives.
Gases used for heating such as methane, propane and butane
are the most common types of gases to cause explosions.
Authorities have confirmed the incident occurred in the evening during peak hour, flipping more than 20 cars.
Egoli Gas claimed the explosion was not caused by a gas leak in media interviews earlier this morning.
