About this topic

Australian Standard AS 1319 governs all safety signs in the workplace. The White Card exam tests your ability to identify signs by shape and colour, not just by reading the words.

Key facts to remember

  • Blue circle = Mandatory (you MUST do this). Example: 'Hard hat must be worn'.
  • Red circle + crossbar = Prohibition (do NOT do this). Example: 'No smoking'.
  • Yellow triangle = Warning / Hazard. Example: 'Danger: electrical hazard'.
  • Green rectangle = Emergency / First Aid. Example: 'Emergency exit'.
  • Red rectangle = Fire equipment location.
  • Tags must only be removed by the person who placed them.
