The most common defense in a retail slip-and-fall case is the wet floor sign. The store placed a caution cone or folding sign near the hazard; the plaintiff failed to see it; therefore, the plaintiff assumed the risk or is comparatively at fault for the fall. That defense is legally viable in some factual configurations and legally deficient in others, and the difference turns entirely on what the evidence shows about when the sign was placed, where it was positioned relative to the hazard, whether it was visible from the direction the plaintiff was approaching, and whether the sign was a substitute for remediation or an accompaniment to it.
What the Defense Must Establish
For a wet floor sign to support a defense verdict, the retailer must generally be able to show:
- That the sign was placed before the plaintiff encountered the hazard, not after the fall
- That the sign was positioned at or near the hazard in a location where an approaching patron would encounter the warning before reaching the wet area
- That the sign was visible from the direction of travel — not obscured by display fixtures, shopping carts, other customers, or narrow aisle configurations
- That the hazard was not so large or so significantly spread that a single caution cone was inadequate to warn of its full extent
Retailers frequently fail one or more of these elements, and each failure opens a distinct line of attack for plaintiff counsel.
Timing: Before or After the Fall?
Surveillance footage is the primary evidence on timing. The video shows exactly when a store employee placed the sign in relation to when the spill first appears on camera and when the plaintiff fell. When the spill appears on camera and is visible to passing employees for several minutes before the sign is placed, the retailer cannot claim the sign was an adequate response. The key analysis is whether the sign was placed in time to warn the specific plaintiff who was already in the aisle or approaching it.
When surveillance footage is not available, preserved, or determinative, depose the employee who placed the sign. Ask specifically: when did you first notice the wet area? Where were you when you saw it? How long did it take you to retrieve the sign? Where was the sign stored? This sequence frequently produces an admission that the employee saw the hazard, retrieved the sign from a stockroom, and placed it after several minutes had already passed.
Placement and the Approaching Patron's Line of Sight
A sign placed behind a display unit, at the end of an aisle, or facing away from the direction the plaintiff was walking does not warn anyone approaching from the other direction. The store's duty is to warn the reasonably approaching patron, not to place a sign in a technically proximate location. If the surveillance footage shows the plaintiff walking down the aisle from the north and the wet floor sign was positioned at the south entrance to the aisle, the warning never reached the plaintiff regardless of how bright the sign was.
Expert testimony from a human factors specialist can support this analysis by explaining the visual field of a typical patron pushing a shopping cart, the distraction effect of store displays and promotional materials, and the detection distance at which a reasonably attentive person could be expected to read and respond to a floor-level sign. This evidence is particularly useful when the defense argues that the plaintiff was looking down at their phone rather than observing the floor.
Sign Adequacy and ANSI Standards
The American National Standards Institute and the International Safety Equipment Association publish standards for safety sign design, placement, and visibility under ANSI/ISEA Z535. While retail premises are not uniformly required to comply with these standards as a matter of law, ANSI Z535 compliance is a recognized benchmark in expert testimony on sign adequacy. A sign that does not meet minimum height, color-contrast, or legibility requirements under the applicable ANSI standard may be argued to have provided inadequate notice even if it was placed at the correct location and time.
When the Sign Does Not Eliminate Liability
Even a properly placed, visible wet floor sign does not extinguish liability if the underlying hazard was not being remediated. A store that places a sign and leaves an expanding liquid spill unattended for thirty minutes while customers walk around it has not satisfied its duty. The sign is a temporary warning measure; remediation is the duty. Where the hazard grew or migrated beyond the sign's zone of coverage while the sign was in place, the store's response was inadequate even if the initial sign placement was timely.
Comparative fault arguments based on the plaintiff's failure to see a sign depend on the jury crediting the sign's adequacy. If the sign was poorly placed or obscured, the comparative fault argument fails with it. Jurors in retail slip-and-fall cases generally respond well to clear evidence that the store knew about a hazard and did the minimum possible to address it.
