How is the height of the tank capacity lettering specified?

The height of the tank capacity lettering is specified as at least 3/4" in height and also includes the option of being at least 1" in height, which means that both of these choices meet the requirement for clear visibility and communication. The designation of a minimum height for lettering serves to ensure that the capacity information is easily readable from a distance, which is essential for operational safety and efficiency.

Having letters that are at least 3/4" or 1" in height supports the need for legibility in various conditions and helps to prevent misinformation about the tank's capacity. This is particularly important in settings where multiple users may need to read the information quickly or where visibility may be challenging due to lighting or distance. Thus, specifying that lettering be at least 3/4" or 1" helps ensure that important data remains accessible and understandable in practical situations.
