Remarks (Other Requirements)_ _______________________________________________________________________ _________________________________________________________________________________________________ Note — 1. By “lethal substances” are meant poisonous gases or liquids of such a nature that a very small amount of the gas or of the vapor of the liquid mixed or unmixed with air is dangerous to life when inhaled. For purposes of this design, this class includes substances of this nature which are stored under pressure or may generate a pressure if stored in a closed vessel. 2. Design parameters may be specified but factory engineers will advise if design calculations or code requirements suggest a better choice.
