A sign is a representation of an object that implies a connection between itself and its object. A natural sign bears a causal relation to its object - for instance, thunder is a sign of storm. A conventional sign signifies by agreement, as a full stop signifies the end of a sentence.
Examples of signs in the industrial context include:
- Warning signs indicating potential hazards or dangerous areas
- Directional signs indicating the location of exits, restrooms, or specific departments
- Safety signs indicating the proper use of equipment or protective gear
- Informational signs displaying company policies, schedules, or company history.
