Design Propane tanks don't require secondary containment. Right?

I'm having an argument at work that propane nor refrigerant tanks secondary containment. I don't believe they require it, as that's how I've always seen them built and I can rationalize why. But I can't seem to find anything to support that.

Looks like NFPA 58 covers liquified petroleum gas, which is likely to encompass propane. I would get your boss to pay for a copy, or find a free pdf online and consult that

As others have said, NFPA allows you to download free copies of their codes. I believe you need to create an account. I've done it before so can confirm.
