AWS F3.2M/F3.2

Abstract

This guide outlines recommended principles of ventilation systems for facilities with welding and allied processes. It is intended for those responsible for selecting and designing such systems. The primary objective of this document is to enhance the health and safety of all in the industrial environment. The secondary objective is energy conservation. This guide does not provide information on respiratory protection devices such as respirators, or specific precautions for confined spaces.<br>This standard makes use of both U.S. Customary Units and the International System of Units (SI). The measurements may not be exact equivalents; therefore, each system must be used independently of the other without combining in any way. The standard with the designation F3.2M:2001 uses SI Units. The standard designation F3.2:2001 uses U.S. Customary Units. The latter are shown within brackets [ ] or in appropriate columns in tables and figures.
