Practical Notes

Always include a legend on the drawing that explains all the symbols used, as per the standard's recommendation.

Ensure symbols are drawn to a consistent scale and are clearly distinguishable, especially on complex floor plans.

The standard provides guidance on using colors (e.g., red for fire-fighting equipment) to enhance legibility; this should be followed where possible.
