Minimum height of symbol (Z=100)	60mm	90mm	120mm	150mm
Note: The luminous factor (Z=100) from SS 563 is used to determine the size of the sign. It essentially dictates the size of the sign that varies with distance. The graphical symbol for firefighting equipment shall be sized such that the height and width are same. The size of symbol is not inclusive of borders.
