What Are The Reasons Behind The Ahmed Pur Accident?

On June 25, an oil tanker routed from Keamari, Sindh, to Vehari, Punjab, met with an accident. The vehicle overturned and the oil inside quickly spilled out onto the road near village Safeerwala, 6km from Ahmedpur Sharqia. Later, the area ignited.

The Early assumption for the fire was lighting cigarette while reason is different in scientific perspective.

Scientific perspective believes if the petrol is spilled out openly that will be converted into the environment in form of gas and there would be a fat chance of fire when the sun rays are very hot. And the same happens  with Ahmedpur accident.
