The Correct Answer and Explanation is :
The correct answer is 10 ¾ square inches.
Explanation:
The minimum permitted size of a placard is often specified by regulations governing signage, workplace safety, or public notices. In many instances, especially within industries such as hazardous materials or workplace safety, a “placard” refers to a sign that is used to convey important information in an easily visible and legible format.
In the context of hazardous materials (such as chemicals or explosives), the size of the placard is regulated by agencies like the Department of Transportation (DOT) and the Occupational Safety and Health Administration (OSHA). The purpose of these regulations is to ensure that critical safety information is communicated effectively to workers, first responders, and others who may encounter the materials.
For example, the 10 ¾ square inches size (or 10.75 square inches) is typically used in reference to the minimum size for specific types of warning signs or placards in regulated settings like shipping or workplace environments where hazardous substances are present. This size is large enough to hold the necessary symbols, text, or other visual elements required to effectively communicate the safety information, while still maintaining practicality for labeling, display, and readability.
The choice of 10 ¾ square inches ensures that even small placards are large enough to attract attention, meet legal requirements, and convey essential information to people who might need to act based on that information. Smaller placards (such as four or seven square inches) would not provide sufficient space for the necessary details, potentially compromising the safety and clarity of communication.
In summary, 10 ¾ square inches is the minimum permitted size for a placard in certain regulatory contexts to guarantee the effectiveness of safety communication.
