A product is in a defective condition if it is unreasonably dangerous to the user or to (the) consumer who purchases the product and causes physical harm. Defective product cases fall under product liability law – legal issues that arise after a dangerous or faulty item causes an injury.When a defective product causes harm, victims may be entitled to compensation under Pennsylvania's product liability laws. Businesses must develop and produce safe products to meet legal obligations. To determine the parties responsible for damages, the injury-causing defect must be accurately assessed in order to appropriately assign fault for damages. A claim for a defectively manufactured product alleges that the product was flawed because of an error while making the product. This type of defect affects every unit of the product, meaning that any consumer who uses it is at risk. Defective design claims revolve around an inherent flaw in the product design that created an unreasonable danger. The test asks the question whether a consumer would reasonably anticipate and appreciate the product's danger and its potential to cause injury. Similarly, a fuel tank that hasn't been designed properly can cause death or catastrophic injury during an explosion in a vehicle collision.
