Review a strict-products-liability warning-defect problem with examiner-style analysis on adequate warnings, foreseeable misuse, and sophisticated-user arguments.
KiteLine Labs manufactures a concentrated drain cleaner sold to homeowners in a one-liter bottle. The label warns: "Wear gloves. Avoid eye contact." The product also reacts violently if mixed with bleach, releasing a toxic gas. KiteLine knew from prior consumer complaints that customers commonly stored the cleaner under the sink beside bleach and sometimes combined the two while trying to unclog slow drains. But KiteLine chose not to add any warning about mixing because its marketing team thought a stronger warning would reduce sales. Paula bought the cleaner, used it exactly for its intended purpose, and then poured a small amount of bleach into the same drain when the clog remained. Toxic gas filled the bathroom and severely injured her lungs. Paula sues KiteLine on a strict-products-liability theory for failure to warn.
Paula likely can recover because the drain cleaner was defective due to an inadequate warning about a serious and reasonably foreseeable bleach-reaction risk. A commercial seller is strictly liable for injuries caused by a product sold in a defective condition that is unreasonably dangerous to the user. A product may be defective not only because of a manufacturing or design flaw, but also because it lacks adequate instructions or warnings about non-obvious risks associated with intended or reasonably foreseeable uses. The warning must reasonably alert ordinary users to material dangers and how to avoid them. A seller is not required to warn about dangers that are open and obvious to ordinary users, but it must warn about serious dangers it knows or should know ordinary users are unlikely to appreciate on their own. Foreseeable misuse can still require a warning when that misuse is common enough to be part of the real-world use environment. In strict liability, the focus is the product’s condition and warnings, not the seller’s due care, though knowledge of repeated incidents may show the warning was inadequate.
Can Paula recover on a strict-products-liability warning-defect theory even though the drain cleaner worked as intended and the bottle warned about some risks?

Paula has a strong warning-defect claim. KiteLine sold a chemical product for household use and knew consumers commonly kept it near bleach and sometimes combined the two while trying to clear a stubborn drain…
