How much static charge is required to ignite gasoline fumes?

The ignition of gasoline fumes can occur with a static discharge of as little as 1,500 volts. This voltage threshold is significant because gasoline vapors can ignite readily in the presence of a spark or static electricity. When static electricity accumulates on a person's body or on an object, it can reach levels much higher than typical electrical voltages encountered in everyday life, and once it discharges, it may create a spark that is capable of igniting flammable vapors.

In environments where gasoline is present, it is crucial to be aware of static electricity and to take precautions to minimize the risk of ignition. This understanding is important for safety protocols in fueling areas, maintenance of equipment, and handling flammable substances. Therefore, the choice reflecting 1,500 volts is indicative of the potential hazards associated with static electricity in volatile environments.
