What is another term used to describe the explosive range?

The explosive range refers to the range of concentrations of a substance in the air that can ignite and produce an explosion. The term "flammable range" is specifically used to describe this concept as it captures the minimum (lower explosive limit) and maximum (upper explosive limit) concentrations that can sustain combustion. This range is crucial for understanding safety protocols in environments where explosive or flammable materials are present, as staying within this range can lead to an explosion, while being outside of it means the substance is either too lean or too rich to ignite.

The other terms, while related to fire and combustion, do not accurately describe the concept of explosive concentration range. The combustible area might imply regions where combustion can occur, but does not specifically reference the concentration limits like the flammable range does. Ignition zone implies a more active area of combustion but lacks the necessary specificity regarding concentration. Detonation field is more commonly associated with a different type of explosive reaction and does not convey the same concept as the flammable range.
