RE: Use of a triangle on warning labels
European Community Safety Signs Directive (EEC/92/58) Warning - black bordered triangle with yellow back ground and black symbol Prohibition - red circle and red diagonal line, white background, black symbol Mandatory - circle, blue background, white symbol Information - square, green background For UK refer to HS Safety signs and signals regs 1996.

For example, IEC 61010-1 Table 1 only indicates 3 symbols that have the triangle enclosing the symbol. While, IEC 60417 does not indicate this.

RE: Use of a triangle on warning labels
Doug - I have a copy of ISO 3684:1984 (quite old) in which the geometries of safety signs are described: circle: prohibition or mandatory action triangle: warning square or rectangle: information (including instructions) One must assume (since it's not said in ISO3684:1984, ISO3641:1988, IEC60417-1:1998 or IEC60417-2:1998; though it may be in IEC60416, which is reference in the scope of IEC60417-2:1998 and is a normative reference in IEC60417-1:1998) that just a symbol for a product marking, without a surrounding geometric emphasis, is the same as if the symbol were on a rectangular sign. Answer to your trivia question - Per ISO 3684:1984, the slash runs 10:00 to 4:00 for a prohibition sign. This is not always followed, if the ISO 7000:1989, Symbol 0506, is any example.

RE: Use of a triangle on warning labels
Doug, the triangle is intended for a warning sign and is specified in ISO 3864. The circle has the meaning of prohibition or mandatory action, and the rectangle is for information including instructions. The diagonal line in a circle is at 45 degrees. The standard covers all aspects of the design of these symbols.
