Failure to warn is a claim that a responsible party did not provide adequate warnings about a known or foreseeable risk.
It is common in product liability but can also appear in other safety-related settings.
Why failure to warn matters
Some products or activities cannot be made risk-free. Warnings can help users understand hazards, limits, and safe-use instructions.
The legal issue often asks whether the warning was needed, clear, prominent, accurate, and connected to the harm alleged.
Where failure to warn appears
Failure-to-warn claims appear in product liability cases, medication and medical device disputes, chemical exposure cases, workplace safety cases, consumer product cases, and equipment accidents.
Evidence may include labels, manuals, training materials, prior incidents, expert testimony, and industry standards.
How it differs from nearby terms
Failure to warn concerns inadequate risk communication. A design defect concerns how the product was designed.
Negligence is broader and may involve many forms of unreasonable conduct, including but not limited to warnings.
Practical example
A power tool has a hidden kickback risk under common operating conditions. If the manual and label do not clearly warn about that risk, an injured user may allege failure to warn.
