scope:

This publication is intended for the suppliers, distributors, and users of hydrogen selenide and its handling equipment. The publication includes guidance for design of equipment, cylinders and valve usage, handling controls, and safety. Guidelines on the operational steps associated with the use of hydrogen selenide and hydrogen selenide mixtures as well as fire protection, gas detection, ventilation, and related safeguards are also included. The manufacture, purification, and analysis of hydrogen selenide are beyond the scope of this publication, although the general guidance given is also relevant to these processes.

Purpose

This publication was written to address the high toxicity and flammability of hydrogen selenide where the consequences of improper handling of hydrogen selenide could cause injury, death, and/or facility damage. This publication will provide a description of the potential hazards involved in handling hydrogen selenide and the guidelines to be taken to minimize risk potential.
