How to mark floors

Warehouse floor markings play a critical role in maintaining a safe and efficient work environment. These markings can be used to indicate safe and efficient routes and point out hazards to warehouse employees and others.

For warehouse floor markings to function as intended, certain best practices should be followed when they are applied. If best practices and available official guidelines are ignored, the markings could create confusion and put your workers at risk.

In this guide, we’ll be explaining the process you should follow when marking out your warehouse floor. We’ll also explain why floor marking is essential to your warehouse, OSHA’s guidelines on the same, and factors you should consider before, during, and after this exercise.

Why is Floor Marking Important In a Warehouse?

Floor markings are a simple yet effective method of communication inside warehouses. They are hard to miss and quickly alert workers to anything they should take note of when working in or passing through any area.

The main impact of these lines is they help keep workers safe. Floor markings separate human and vehicular traffic and make the presence of hazards and safety equipment obvious. This also helps the company comply with industry regulations and avoid costly fines.

Floor markings also make warehouse operations more efficient. They can be used to define an organizational system that makes it easier to locate items. When defined pathways are kept clear, the flow of goods and materials is also uninterrupted.

Environments that are safe and well-organized are good for staff morale. Therefore, floor markings can also indirectly contribute to overall worker productivity.

What are the OSHA Guidelines for Floor Marking?

OSHA does not offer detailed guidelines regarding floor marking. The manner of implementation is largely at the discretion of the company or warehouse manager. However, there is one OSHA regulation on floor marking and other guidelines have inspired certain best practices.

Marking of Aisles and Passageways

OSHA regulation 1910.176(a) states that Permanent aisles and passageways must be marked in some way. Although this regulation doesn’t state that the markings must be on the floor, this has been the standard interpretation of this regulation.

 

An aisle or passageway refers to the route followed by pedestrians or mechanical equipment like forklifts. This regulation helps to separate the two, lowering the risk of accidents.

Using Colors to Identify Hazards

OSHA regulation 1910.144(a) outlines the use of red and yellow colors in industrial environments. It states that fire protection equipment, emergency stop bars and buttons, and anything associated with danger should be identified using the color red.

Yellow is to be used to identify physical hazards such as something that can cause tripping or falling. It is standard practice to use these colors for similar purposes in floor markings.

Width of Floor Markings

Although it’s not an official regulation, OSHA did recommend in an interpretation of its regulation on floor markings that the width of the markings be between 2 and 6 inches. This has also been adopted as a best practice.

Warehouse Floor Marking Steps

The specific steps you’ll take to mark your warehouse floor will be determined by the marking material and the types of marks you’ll need to make. However, some steps should be part of any warehouse floor marking process.

Plan Ahead

Floor marking can be time-consuming and labor-intensive. It can also affect regular warehouse operations leading to downtime and loss of productivity. It’s useful to have a strategy to apply the markings in a manner that’s efficient and causes minimal disruption.

You should start by mapping out the warehouse and identifying and separating different zones. The next step would be to identify marking needs in individual zones including:

  • Separate aisles and passageways for pedestrians and vehicles.
  • Hazards
  • Work zones or cells
  • Equipment storage areas
  • Raw material, WIPs, and finished goods storage areas, etc.

Once these have been identified, you can make decisions such as the types of marks and materials needed and how to work from one zone to the next to minimize disruption.

Choose a Material

Paint and tape are the most common material options for this job. Paint is usually more durable than tape. However, surface preparation takes longer and paint needs several days to dry and cure. Paint also releases fumes when wet and removal of painted lines is challenging.

While tape is less durable than paint, it’s easier to apply and application causes little disruption since the area can be used immediately afterward. Cleaning the floor is the main form of preparation needed and tape can also be used on wooden floors.

Higher grades of warehouse floor marking tapes last longer in areas with heavy traffic. It’s also easy to add graphics and text to floors using preprinted tape.

Test the Materials and Logistics

Conducting an accelerated wear test on tape can help you decide which type will perform best. This can be done by applying a length of tape to the floor and dragging a loaded pallet over it a few times using a forklift.

The idea is to check for tears, lifted edges, and anything else that tells you how much effort it takes to damage one type of tape vs another.

You should also test the logistics of your planned markings to see if people will intuitively follow them or if they’ll be disregarded.

Apply Markings

To install tape you’ll need some cleaning supplies, e.g., brooms, cleaning alcohol, and rags. Once the surface is clean, you can use a measuring device, a string, and weights to ensure your marks are applied in a straight line. The tape should be tamped down afterward.

Painting markings may require surface preparations like etching to ensure the paint adheres to the concrete surface. The different paint colors will have to be mixed separately, applied, and given time to dry before being exposed to traffic.

Train Employees

When the floor markings are in place, it’s important to train your employees to ensure they understand what different markings mean. You should also post a color code chart so they can reference what different colors mean at any time.

Monitor and Maintain

Even the most durable floor markings will undergo wear and tear. Markings in heavily trafficked areas are likely to wear much faster than those in others. Inspect the markings regularly.

In case of accelerated wear, you can explore other types of markings for such areas or adopt a schedule for maintaining the markings.

Factors to Consider

Getting the most out of your warehouse floor markings requires you to consider certain factors before you apply them. Such factors include:

  • Ideal Line Width: Pick a line width that’s thick enough to be visible but not too thick that the line color will be confused with the floor color.
  • Shapes: A single length of shape is easy to apply but doesn’t suit every situation. Corner markers, x-markers, and smaller shapes are better for defining certain spaces.
    • Minimal Colors: Too many colors will confuse workers
  • Temporary Markings: If a layout change is likely in the near future. Use markings that will be easier to remove such as tape.
  • Allowances: Ensure there’s enough allowance between markings for turning forklifts and other situations where more space than usual is needed.

Conclusion

Floor markings are a simple approach to making warehouses safer, more organized, and efficient. The markings also help with compliance. Following industry best practices makes it more likely that these markings will have the desired impact.

The process of applying warehouse floor markings can be disruptive and requires a proper plan to improve execution. Decisions such as choice of material are critical for ensuring the process causes as little downtime as possible.

It’s also important to train workers to ensure they know what the markings mean. Putting up printed color charts around the warehouse also helps. Factors such as using the right shapes and the right colors will maximize the impact of your warehouse floor markings.
