The flash point of gasoline is -50℃, and the explosion range is 1.3%-6.0%.

Extended data

Gasoline is a poison that paralyzes the nervous system. Acute mild poisoning is similar to drunken symptoms, such as dizziness, headache, nausea, weakness, vomiting, unsteady gait, blurred vision, trance, and may lead to hysteria. Severe poisoning will immediately lead to coma, convulsions and other serious heart, brain and blood system diseases. If you accidentally inhale gasoline into your lungs, it will cause aspiration pneumonia.

The automobile exhaust using leaded gasoline contains lead, which is a toxic and harmful heavy metal and is inhaled with the air. It is harmful to health, especially to children, and will affect their intellectual development. Therefore, long-term inhalation of volatile gasoline is harmful to the health.
