What is dynamic coefficient of friction?

The coefficient of friction measures a surface’s frictional resistance to a moving object. “Dynamic Coefficient of Friction” (DCOF) ratings are established by a tribometer.

​DCOF ratings are split into three ranges between .0 and 1.0. Floors with higher DCOF ratings (above .42) are safer for customers, employees, clients and patients. Floors with lower ratings are more dangerous.

Why does it matter?

Slip, trip and falls are one of the most expensive aspects of running a business. About 85 percent of workers comp claims come from slip-and falls at an annual cost of $70 billion. Falls account for 8 million ER visits every year. Preventing even one slip, trip and fall claim can save your business $20,000.
