What is the required size of the word “NOTICE” on pesticide signs for clarity?

The specified requirement for the size of the word "NOTICE" on pesticide signs is crucial for ensuring that the information is clearly visible and easily readable to the public, which improves safety and awareness. The requirement for the word "NOTICE" to be 2 ½ inches in height strikes a balance between visibility and practicality, allowing it to be seen from a reasonable distance while not being excessively large for standard signage use.

Choosing a height of 2 ½ inches ensures that individuals passing by can quickly recognize and read the sign without any ambiguity. This size is adequate for effective communication of important information, such as pesticide application, and helps ensure compliance with safety regulations. When displayed correctly, the word "NOTICE" at this size successfully meets the intended purpose of alerting individuals in the vicinity about pesticide use, thereby enhancing safety awareness in areas where chemicals are applied.
