What is the primary purpose of a safety sign that says “Authorized Personnel Only”?

The primary purpose of a safety sign that reads “Authorized Personnel Only” is to restrict access to hazardous areas. This sign plays a crucial role in maintaining safety within a work environment, particularly in settings where certain regions may pose dangers to individuals who are not properly trained or equipped to deal with the potential risks involved. By limiting access to these areas, the sign helps ensure that only those with the appropriate safety training and authorization are permitted entry, thereby reducing the likelihood of accidents and injuries.

Other options do not focus on access control to dangerous locations. While teamwork among employees is important in many work environments, it is not a function of this specific sign. Information about safety equipment is also unrelated; such details would typically be included on different types of safety signage or instructional materials. Emergency exit signs serve a distinct purpose by guiding personnel in case of an emergency, aimed at facilitating safe evacuation, rather than controlling who has access to certain areas. Thus, the sign's focus on restricting access is critical for maintaining workplace safety.
