What is one primary function of signage in an industrial security program?

• A. It informs, warns, guides behavior, and reinforces surveillance and restricted-area boundaries.
• B. It increases energy consumption.
• C. It serves as the sole barrier to entry.
• D. It determines compensation for employees.

Answer: (D)

Signage in an industrial security program communicates important information that shapes how people behave around safety and access. It informs workers and visitors about hazards, marks restricted areas, warns of risks, and guides movement so people know where they can go and what procedures to follow. It also reinforces that certain areas are under surveillance or require authorization, helping deter unauthorized access and support quick responses if something goes wrong. This combination makes signage a key part of preventing incidents and ensuring proper behavior on site.

The other options don’t fit: signs aren’t primarily about increasing energy use, they aren’t the only barrier to entry, and they have no role in determining employee pay.
