Requirements for lethal service are scattered through VIII-1, the code cases and the interpretations. ASME VIII-1 section UW-2 has most of the requirements for lethal service. Two definitions of lethal service are provided in UW-2. The second definition is also duplicated in the end notes:
It is up to the user to determine if a service is lethal. We at Pressure Vessel Engineering do not determine if the vessel service is lethal (but we might have opinions based on previous jobs).
When it has been determined that a vessel is in Lethal Service, some of the following code sections will apply. Other code sections might also be required. (List last updated June 16 2015 based on the ASME 2013 VIII-1 code edition.)
By "lethal substances" are meant poisonous gases or liquids of such a nature that a very small amount of the gas or of the vapour of the liquid mixed or unmixed with air is dangerous to-life when inhaled. For purposes of this Division, this class includes substances of this nature which are stored under pressure or may generate a pressure if stored in a closed vessel.
