Description
This recall involves Pro Supply Outlet sodium and potassium hydroxide products sold in two-pound rigid white plastic jars with continuous thread caps. The front of the label bears the PSO logo, the product name, SKU 7023 and UPC 078345004533 for the sodium hydroxide and SKU 7132 and UPC 078345004625 for the potassium hydroxide.
Hazard
The products contain sodium hydroxide or potassium hydroxide which must be in child resistant packaging, as required by the Poison Prevention Packaging Act (PPPA). The packaging of the products is not child resistant, posing a risk of chemical burns and irritation to the skin and eyes. In addition, the label on the product violates the Federal Hazardous Substance Act (FHSA) by omitting the word "poison" for poisonous chemicals.
Remedy
Consumers should immediately store the recalled products in a safe location out of reach of children and contact Pro Supply Outlet for a free replacement child-resistant cap and label to put on the product. Pro Supply Outlet is contacting all purchasers directly.
Incidents and injuries
No incidents or injuries have been reported.
