禁止标志制作英语怎么说

"Prohibition signs" or "no symbols" is the term used to describe a type of sign used to indicate that certain actions or behaviors are prohibited or not allowed. These signs are used in a variety of settings, including public buildings, workplaces, and public spaces, to help ensure the safety and well-being of individuals and to prevent accidents and injuries.
Prohibition signs are typically rectangular in shape and feature a circle with a diagonal line drawn through it, similar to the "no smoking" sign. The circle is often red, and the diagonal line is usually black or white. These signs are intended to be easily recognizable and immediately understood, even by people who may not speak the same language.
The use of prohibition signs is regulated by international and national standards. In the United States, for example, the Occupational Safety and Health Administration (OSHA) has established specific guidelines for the use of these signs, including the colors and symbols that should be used.
Here are a few examples of prohibition signs in English, along with their Chinese translations:
No smoking: 禁止吸烟
No eating or drinking: 禁止食用或饮用
No cell phone use: 禁止使用手机
No open flames: 禁止明火
No unauthorized personnel: 禁止未经授权的人员进入
例句：
"There are prohibition signs posted all around the construction site to prevent accidents and injuries."
"Please follow the prohibition signs and do not bring any open flames into the laboratory."
"The no smoking sign on the door clearly indicates that smoking is not allowed inside the building."
