Part 1 explains how to layout the components of safety signage, dictate the color scheme and sizing information. Part 2 covers the same concepts as part one, but specifically for labels applied on machinery, vehicles and consumer goods. Part 3 contains guidance for designing new safety symbols. Part 4 specifies the standards for [[Phosphorescence|phosphorescent material]] and colours of a sign, as well as testing to confirm these signs meets required standards.
