FDNY CoF - Non‑Flammable Compressed Gases (G‑46) Practice Test

The correct answer is 68 degrees Fahrenheit, which is typically considered the standard temperature for defining gases under normal atmospheric conditions. At this temperature, many substances exist as gases, particularly those classified as non-flammable compressed gases, such as nitrogen, oxygen, and argon. The significance of this temperature relates to the conditions under which these gases become relevant for handling and storage in various industrial and commercial applications.

In technical scenarios, many gases can be compressed and stored at higher pressures, but under standard conditions (often defined as 68°F and 1 atmosphere of pressure), a gas remains in its gaseous state. This temperature is a useful reference point when discussing the behavior of gases, their properties, and safety protocols required in storage and usage.
