Safety information
Every gas monitor installation should be risk assessed. The correct location of monitor(s) must
consider the potential sources of gas leaks and the location of expected human occupation in
the area. Where large areas must be monitored, it is often advised that no single monitor
should cover a volume in excess of 80m

. The installation of more monitors should be
considered where an area is complex in shape, filled with obstacles, has a lack of ventilation or
air circulation, or if there are dead zones where gas can collect
