What exactly does the UW-2 lethal substance refer to in ASME VIII-1?

Perhaps this is the online version; there is only one annotation regarding the lethal substance, but it cannot be found. Please help to look into it, thank you!
It’s not a version issue; it’s the postnote at the end of the file, NN-6. 65 A “lethal agent” refers to a toxic gas or liquid such that even a very small amount of its vapor (whether mixed with air or not) inhaled by a person can be fatal. This volume deals with toxic substances that generate pressure when stored under pressure or in sealed containers.
