How to keep the dirt out
The 15 foot rule
Have you ever said to yourself, "How do I keep the dirt outside and get it off of people’s shoes? It is a common frustration for facility managers and janitorial staff is how much dirt and grime can be tracked into a building from the outside world.
As much as 70% to 80% of interior soil is brought into your facility from foot traffic.
A good rule of thumb is to use a minimum of fifteen feet of floor matting or carpeting length at your entrance. At least fifteen feet is required to remove the majority of dirt and moisture from foot traffic at your entrance.
With fifteen feet of matting each foot makes contact with the mat at least three times.
By laying a minimum of fifteen feet of floor mats helps to ensure that the majority of exterior soil will be stopped at the entrance. Everyone benefits from the inherently cleaner environment, janitorial staff can spend less time sweeping and mopping and focusing on other important things, and it even gives you that much extra space to add to the aesthetic and branding of your company or facility by choosing the right entrance mat and adding your logo or company name.
- 70% to 80% of inside dirt comes from foot traffic
- 15 feet of matting allows each foot to touch the mat 3 times
- 15 feet knocks of the majority of soil that would otherwise be in your building
