Quick Answer
A cone placed before the fall for the same hazard may help establish knowledge. Check:
- Who placed it and why.
- Whether it was already there. A photograph taken after the fall cannot establish that.
- Which condition it marked. Cleaning or rain precautions may address a different condition.
Walmart may also argue that the cone adequately warned the customer. Its timing and position matter to that argument.
Take Competing Explanations To The Case Review
Imagine a photograph of a customer on the floor beside a yellow cone. Save it, and look for an earlier view of the same part of the aisle to investigate when the cone arrived. The photograph alone cannot supply that time.
For the case review, record what the available evidence shows before explaining why the cone was there. Its arrival, movement or intended wet area may still be unknown. Test the possible explanations against the records instead of choosing one from the photograph alone.

| Possible account to examine | Records and questions to compare | Limit that remains |
|---|---|---|
| Was the cone placed before the fall in response to the same hazard? | Look for the earliest evidence showing the cone. Find out who placed it and why. | If that pre-fall placement for the same hazard is established, it may help show knowledge of the condition. Warning adequacy remains a separate question. |
| Was the cone moved during the response before the photograph was taken? | Record every location and time the evidence supports, including any movement. Staff may have left the cone in a different place after responding from where the customer would have encountered it. | The scene may have changed. A photograph taken after the accident cannot establish the cone’s earlier position or when it arrived. |
| Was the cone marking another wet area or precaution? | Identify the wet area the cone was intended to mark. Recently mopped tiles and a separate spill farther down the aisle may be different conditions. Ask the person who placed it which condition it addressed, if that person can identify it. | The cone beside the mopped tiles does not explain staff’s knowledge of the separate spill. A spill report, cleaning task or rain precaution may explain why it was placed. The photograph alone does not establish which explanation is correct. |
Record these observations separately:
- A witness may remember the cone before the fall.
- Footage may first show the cone after an employee comes to help.
The footage’s first image of the cone does not establish its arrival time. Do not combine the two observations into an assumed arrival time.
The cone’s arrival time may be known even when the time the liquid has been on the floor is not.
- Keep a separate account for each speaker, recording when that person observed the wet area or took action.
- Record the alternative explanations and retain evidence supporting or contradicting each one.
- Compare the cone placer’s explanation with cleanup requests and reports that may corroborate it.
For the rest of the claim, see the Walmart knowledge hub. The inquiry here is narrower: what can the available evidence establish about this warning device?

Examine The Warning From The Customer’s Approach
Walmart may argue that the cone adequately warned the customer even if it marked the same condition before the fall. Assess this customer’s opportunity to see and react, the warning’s visibility and the particular danger it conveyed. Knowing who placed the cone does not answer those questions. Evidence that the store knew about the condition does not settle warning adequacy either. Review both knowledge of the condition and warning adequacy: neither establishes negligence on its own.
If it is safe, take photographs along the customer’s approach route. A close-up of the cone’s printed face may omit an obstruction or show a face the customer never saw. Wider photographs can show the spill’s extent, the approach and objects that might block the warning.
In Sparkman, there were two warning cones in a wet entryway. The court upheld the jury's inadequate-warning finding on the record, including evidence about the cones' size and placement. Their existence did not settle adequacy.
Wal-Mart Stores, Inc. v. Sparkman, No. 02-13-00355-CV (Tex. App.—Fort Worth Dec. 11, 2014).
Examine this customer’s opportunity to see and react. Sparkman concerned the evidence in that case; its holding does not make every cone inadequate.
Preserve the cone’s position and the records
- Leave the cone where it is. Record any changes others have already made.
- Retain the original photographs with their capture times.
- Where footage may show the cone arriving or moving, preserve the sequence that could establish those events.
Match the questions to the available records
Take the photographs and footage to the case review, with each person’s separately recorded account. Beside each question below, name the record that helps answer it. If the answer is still unknown, say so.
- Which condition did the cone address?
- What is still unknown about the cone’s placement?
- What could the customer perceive before reaching the wet area?
Preserve the material promptly for the case review.
