Can you help explain two entries in NFPA 13-2019 Table A.20.4(b) for "Empty Containers" on page 418?
Rigid plastic (not including PET) up to 32-oz. (1L) is non-expanded.
Rigid plastic (not including PET) greater than 32-oz. (1L) is expanded.
What are they referring to? Is this a one-gallon PE bucket? A 64-oz. detergent bottle? Milk crates?
I guess my question is - what is a rigid plastic container?
There's a huge difference if it needs to be treated as an Exposed Expanded Group A plastic versus Non-Expanded.
