Florida’s slip-and-fall statute, F.S. 768.0755, requires that if a person slips and suffers injury in the fall on a transitory foreign substance in a business establishment, that person must first prove the business had actual or constructive knowledge of the hazard and therefore had a duty to actively remedy it. Actual knowledge could be shown if the business created the condition or if a staffer or manager was informed directly of the floor’s condition at that time and location. Constructive knowledge is a bit trickier. It is shown by proving the condition existed for such a length of time that the business establishment should have learned of it in the exercise of ordinary care OR that the condition occurred with regularity and was thus foreseeable.
