What is the explosive range of gasoline?

The explosive range of gasoline is defined as the concentration range within which gasoline vapors can ignite and cause an explosion when mixed with air. The correct answer, which states that the explosive range of gasoline is between 1.4% and 7.6%, aligns with established safety data and chemical properties of gasoline. This range indicates the minimum and maximum concentration of gasoline vapor in air required for combustion to occur.

Understanding this range is crucial for firefighters and others dealing with hazardous materials. It helps in assessing the potential risks during an incident involving gasoline, guiding both the prevention of fires and the planning of safe operational procedures for containment and firefighting.

Other ranges either underestimate or overestimate the concentration, which could lead to unsafe assumptions and inadequate safety measures in fire-related emergencies. This understanding is vital in ensuring the safety of firefighters and the public in the event of a gasoline spill or fire.
