FYI,你的理解我觉得基本正确
Product liability encompasses a number of legal claims that allow an injured party to recover financial compensation from the manufacturer or seller of a product. In the United States, the claims most commonly associated with product liability are negligence, strict liability, breach of warranty, and various consumer protection claims. The majority of product liability laws are determined at the state level and vary widely from state to state. Each type of product liability claim requires different elements to be proven to present a successful claim.
从上述引文可以看出Negligence和strict products liability 都是产品责任的其中一种类型，其中strict products liability 建议翻成无过失责任准确些，因为是两种不同类型，我觉得将翻成collapse翻成重叠要好些，供参考。最好一句话我觉得翻成“因为原告可在产品警示不全导致其受伤的情况下同时起诉这两种过失。”要好些。
