Why do you need to line mark your warehouse?

There are many reasons why most commercial warehouses make use of line markings for better navigation, safety and accessibility. Not only do they make life easier, they can also lower the risk of workplace accidents.

The use of clear line markings in your warehouse helps you to:

  • Define safe walkways for employees and clients
  • Assign specific areas for the disposal of hazardous waste
  • Designate specific lane ways for transport vehicles and heavy machinery
  • Improve the speed of workflow by decreasing time spent navigating the space
  • Lower the risk of workplace accidents.

Should you plan first before you line mark?

When it comes to line marking a warehouse, planning is key. You may be tempted to figure it out as you go but doing so increases your chances of making mistakes that could lead to workplace accidents and injuries. Before you start applying paint or tape to your warehouse floor, it’s best to sketch a plan on paper or draw it to scale on an electronic system.

How should you prepare your warehouse for new line markings?

You wouldn’t paint the walls of your home without cleaning them first, and the same rule applies when you’re line marking the floor of your warehouse. To make sure you get the job done right the first time, press pause on regular daily tasks to prepare your space. To do so properly, we recommend the following:

  • Sweep down your warehouse floor.
  • Use a scrubber to remove any tough stains.
  • Avoid hosing down your warehouse floor to eliminate the chance of excess dampness at the time you make your line markings.
  • Move all heavy machinery that may block access to areas you need to reach with your line markings.

Do the colours of line markings make a difference?

According to national work health and safety guidelines, it’s important to use specific colours for your line markings, to help your employees and warehouse visitors follow all signals with ease. To make sure your line markings guide people as they should, remember:

  • Use yellow line markings to indicate paths, work cells and traffic lanes.
  • Use red line markings to alert employees to danger zones.
  • Use black line markings to indicate works in progress.
  • Use blue line markings in areas of raw materials.
  • Use combinations of red and white line markings to warn employees of areas that may have restricted access for safety reasons.

Is it better to line mark a warehouse with paint or tape?

Traditionally the choice of paint verse tape has come down to flexibility verses durability, line marking tape gives you flexibility and paint offers durability. However Mighty Line Marking Tape is specially designed to hold up to the rigours of warehouse activity and is unmatched in durability. It is also easy to apply and won’t leave sticky residue when removed, which makes it a pretty strong case for line marking tape.

In the end the choice is yours, consider your options and choose a line marking method that makes sense to you. We do both options and there is pros and cons of each.
