For my display I want to place one of the signs in the following diagram. It will be in front of a WWII ammunition stack representing 40mm Bofors QF rounds as per my previous post http://www.bocn.co.uk/vbforum/40mm-bofors-tube-t9918.html?t=9918 My question is this: which sign should I use?
The prospective signs.
The fire risk classes.
I know its not the last one.
