Abstract

This publication describes the primary hazards, the minimum performance requirements for equipment, and some of the applicable regulations for the transfilling of pressurized liquid oxygen. It is a guide for manufacturers and distributors of equipment used to transfill liquid oxy-gen for respiration as well as for individuals or organizations that perform transfilling activities.

This publication applies to specially designed cryogenic containers including portable containers, vehicle-mounted containers, storage tanks, portable tanks, and trailers.
