What is the minimum height an air compressor should be raised to avoid drawing in flammable gases?

Raising an air compressor above a certain height is crucial for safety, specifically to prevent the unit from drawing in ignitable or flammable gases that may accumulate at lower levels. The correct choice indicates that setting the air compressor at a minimum height of 5 feet provides a sufficient buffer.

At this elevation, the compressor is less likely to be exposed to any vapors or gases that are heavier than air, which typically settle lower to the ground. This is particularly important in environments where flammable substances may be present, as it significantly reduces the risk of fire or explosion by ensuring that the air intake is positioned above potential hazards.

In choosing an appropriate height for the air compressor, safety guidelines and standards often emphasize a minimum elevation to mitigate risks effectively, and 5 feet has been established as a practical standard to balance accessibility and safety.
