Is this a classified area?

Is combustible the same thing as flammable?

IDK, but the sign says combustible and I have many times seen wood referred to as combustible material.

Is combustible the same thing as flammable?

No - they each have specific definitions in NFPA 30.

 

[u791262]

flammable liquids have a flashpoint below 37.8°C (100°F). Combustible liquids have a flashpoint at or above 37.8°C (100°F) and below 93.3°C (200°F).

I was only required to install x-proof seals on diesel installations when a gasoline classification affected it. I did hear that the state of PA requires seals for diesel installations per the Fire Marshal.

 

[u791262]

It should be the Area Classification together with the appropriate code article/section in Chapter 5 that would dictate the use of conduit seals in my opinion.

Diesel does not create fumes that you have to worry about. Throw a match in a bucket of gasoline and it ignites. Do the same in diesel and it extinguishes the match. Until you spray diesel into a mist, you can’t ignite it easily. And it’s a “wet” hydrocarbon...no static buildup.

Out of curiosity, I did what I would have normally done if I had been the PE in Responsible Charge of the project; I downloaded the manufacturer's owner's manual. It has the basis for answering the first question I asked in Post #10.

BTW the third clue in the photo is the vent. The clue outside the photo is the OP's location, assuming that is where the tank will be installed.

Generic specs or general ignorance can cause a vent to be installed in a certain way, so I'm not sure what "clue" you are referring to (especially when the vent cap is not visible in the picture).

Really? There's a sign right next to it. (You may need to expand the photo)

Are you looking at the emergency vent?

 

[rbalex]

Yes

 

[oldsparky52]

That's not the normal vent. On the other end of the tank there is a 2" galvanized pipe going up out of the picture that I believe is the normal vent.

 

[rbalex]

And your point is?

 

[oldsparky52]

And your point is?

I was just trying to understand your clue #3 involving the vent.

 

[rbalex]

AH - I should have said the sign said: "Emergency Vent" - my bad.

Okay, I guess you just aren't going to share ...

 

[rbalex]

Sorry, I was watching a YouTube video. I may watch another but what would you like me to share?

I think he wants some more explanation about why the emergency vent is a clue. Me too.

 

[rbalex]

Well - why would it release? Consider it in the context of the installation's location. (Rancho Cucamonga, California)

No idea what that means.
