Which of the following accurately reflects the ignition temperature range in air?

The ignition temperature range in air is crucial in understanding fire and explosion hazards. The correct choice reflects the widely accepted temperature range at which gases, specifically propane and butane, can ignite when mixed with air. The range of 920°F to 1,120°F indicates the temperatures at which these gases can effectively ignite, resulting in combustion.

Understanding this temperature range is essential for safety measures in handling and using LP gas, as it helps operators identify conditions that could lead to accidental ignition. This knowledge allows workers to implement proper protocols to prevent hazardous situations, such as ensuring that equipment does not operate within this ignition temperature range when flammable gases are present.

Other options present temperature ranges that are either too low or too high, which does not accurately represent the ignition characteristics of LP gas in a typical air environment. Understanding the specific ignition temperature range assists professionals in making informed decisions regarding gas storage, handling, and operational safety.
