Arsine is a toxic, colourless gas with a garlic-like odour. It is shipped as a liquefied compressed gas under its own vapour pressure . It is also supplied in a gaseous state, diluted with other gases under pressure. It is flammable and highly toxic. The issue of the safe handling of arsine is a very important and relevant topic to the compressed gas industry as well as the user community of this specialty gas.
Arsine can be safely handled if equipment is properly designed, maintained, and employees are trained.
This publication is intended for the suppliers, distributors, and users of arsine and its handling equipment. The publication includes guidance for design of equipment, selection of cylinders and valves, and handling controls and safety practices. Guidelines on the operational steps associated with the use of arsine and arsine mixtures as well as fire protection, gas detection, ventilation, and related safeguards are also included. The manufacture, purification, and analysis of arsine is beyond the scope of this publication, although the general guidance given is also relevant to these processes.
The publication is part of the programme to develop Globally Harmonised publications amongst Regional Gas Associations.
