Here’s a detailed look at various design considerations for creating effective warehouse signs:
Colour coding helps in quick identification and can be used to signify different zones, safety levels, or types of operations within a warehouse.
Stick to a consistent colour scheme throughout the warehouse. Use bright, high-contrast colours that are easily distinguishable from a distance. For example, red could be used for emergency or danger signs, while green could indicate safe or general areas.
Font and Size
The consideration of font and size in warehouse sign design is crucial for ensuring readability, visibility from a distance, and compliance with safety regulations.
While designing a warehouse sign, choose fonts that are easy to read/scan from a distance and in varying lighting conditions. The size of the font should be proportional to the size of the sign and the distance from which it will be read.
Avoid using overly stylised fonts or small font sizes that can be difficult to read quickly. The aim is to convey the message as clearly and quickly as possible.
Symbols and Icons
Symbols and icons are used to supplement text or to convey a message quickly without requiring literacy. They are especially useful in multilingual settings.
Universally recognised symbols and icons that are easy to understand should be used in warehouse signs. Place them prominently on the sign and ensure they are large enough to be seen from a distance.
Installing warehouse signs effectively is as important as their design to ensure they serve their intended purpose. Effective installation of warehouse signs involves careful consideration of their location, height, and angle, as well as the method of installation.
Let’s delve deep into the installation tips for effective warehouse sign management.
The location where a warehouse sign is installed plays a pivotal role in its effectiveness and impact. A poorly placed sign can be easily overlooked, negating its purpose. In contrast, a strategically placed sign can enhance workflow, safety, and efficiency.
Here’s a detailed look at why location is such a critical factor in the installation of warehouse signs:
Types of Signs and Ideal Locations
- Safety Signs: These should be installed close to potential hazards, safety equipment, or emergency exits to draw attention immediately. For example, a “Fire Extinguisher” sign should be right above or beside the fire extinguisher.
- Directional Signs: These are most effective when placed at key decision points within the warehouse, such as intersections, entry and exit points, or stairwells, guiding the flow of traffic and reducing confusion.
- Identification Signs: For inventory management, these signs should be placed directly on, or immediately above or beside, the shelves, racks, or zones they are identifying. This aids in quick and accurate item retrieval.
- Operational Signs: Signs that give instructions for machinery operation or loading/unloading procedures should be placed where the action occurs, such as near machinery controls or loading docks.
Height and Angle
The height and angle at which a warehouse sign is installed are critical elements that can significantly impact its visibility and effectiveness. Incorrectly positioned signs can lead to misunderstandings, inefficiencies, or even safety risks.
Here’s a detailed look at why height and angle are such crucial factors in the installation of warehouse signs:
- Eye Level: Generally, signs should be installed at eye level to ensure maximum visibility. However, the specific height may vary depending on the type of sign and its intended audience.
- Floor Signs: These should be placed in areas where they are not obstructed by equipment or inventory. The height, in this case, is literally at floor level, but visibility should still be a primary concern.
- Hanging Signs: These should be hung at a height where they are easily visible but not so low as to pose a risk of collision or obstruction.
Angle for Optimal Visibility
- Reading Angle: The angle at which a sign is placed should allow for easy reading from the most common viewpoints. For example, a hanging sign might be angled downward for better readability from below.
- Multiple Angles: In some cases, signs may need to be visible from multiple directions. Dual-sided signs, or those with a three-dimensional shape like cubes or triangles, can be effective in these scenarios.
- Avoiding Glare: The angle should also be adjusted to minimise glare from overhead lighting or natural light, which can make the sign difficult to read.
Adhesive vs. Screw-in
The method used to secure a warehouse sign—whether adhesive or screw-in—can significantly impact its durability, ease of installation, and adaptability to different environments.
