Air compressor in Fuel storage room

[chaterpilar]

I saw in a factory i visited a 5 Hp 3phase driven air compressor installed in a room which has diesel storage tanks ( day tanks) for generators.

I am sure that under some NEC code this would be violation..

Is this acceptable or any particular code disallows this installation.

Any thoughts..

Theres only a few 500's that you can look at...

Seems it'd be a call of the AHJ in Saudi Arabia. :smile: They like buildings codes!

Seems to be more of a building classification problem to determine what
the structure/building is to be require electrically. Art. 510 which points to 511 through 517. But, you said a factory, which would require decidicate space and again a building issue as to seperation via construction to obtain, "classifications of locations", 505.5, so you got a real nice mixed bag there.

Hopefully the services for all the equipment are well spaced or even sudo partitioned off.

Nema 4x,(explosion prof) rated disc's and rigid to some point up up the wall.

Treat or think of it as a Gas Station, they got air compressors, does it past muster ?

What is the flash point of the diesel and what is the ambient temperature? Diesel is classified as a combustible and not a flammable and may not require any classification or explosion proof electrical equipment.

Good Point

Good Point

A google choice, flash point of diesel, on Diesel was "Flash Point is the lowest temperature in which fuel can be ignited. Diesel fuel is typically assigned a Flash Point of between 100 to 160? Fahrenheit"

well see " D-93 "

Point taken though, good catch...

"Flash Point is the lowest temperature in which fuel can be ignited.

That is not exactly correct. Flash point is the lowest temperature at which the liquid will give off enough flammable vapor to support a "flash" fire. The flash point is much lower than the ignition temperature of the fuel.

beware of ethanol blended diesel due to it's LOW flash point

I was not aware that ethanol was being used in diesel. Do you have any additional information on that?

When I was researching ethanol last week I read/heard that diesel/ethanol mixes are actually harder to ignite in the cylinder, thus requiring engine modifications.
