- Aisle Marking: Defines clear, safe walkways for pedestrians, separating them from vehicle traffic (like forklifts).
- Hazard Identification: Marks off dangerous areas, such as around machinery, electrical panels, or chemical storage.
- Emergency Preparedness: Creates clear paths to exits, fire extinguishers, eyewash stations, and first-aid kits.
- Workspace Boundaries: Designates specific areas for different activities (e.g., "work-in-progress," "finished goods," "quarantine").
- Shadow Boards & Tool Locations: Outlines where tools, trash cans, pallet jacks, and other items should be stored.
- Traffic Flow: Directs the flow of vehicles and people to prevent collisions and congestion.
- By using a consistent color and pattern system throughout a facility, everyone—employees and visitors alike—can instantly understand what the markings mean.
