The risks posed by exposure to inerting gases in the open air

In 2001 there was a series accident offshore in which employees were overcome by inerting gases while working in the open air. The accident occurred during maintenance work on an inert gas piping system and could potentially have resulted in one or more fatalities, similar incidents have occurred elsewhere. This Information Sheet, which replaces Safety Notice 3/2002, provides guidance on the risks associated with inerting gas, even in open and apparently well ventilated spaces.
