An introduction to atmosphere furnace safety

摘要

Heat treating is a dangerous occupation. Furnaces are inevitably hot and the treatment atmospheres comprise a wide range of potentially dangerous gases. This article outlines the potential hazards associated with the use of furnaces, particularly when atmospheres are employed that have risks of explosions, burning, toxic effects and asphyxiation. It suggests ways in which those risks can be minimised and reviews the guidance provided by some relevant safety standards.
