A tort is a wrongful act (other than a breach of a contract) that creates civil legal liability for money damages—and in some situations entitles the injured party to injunctive relief—an injunction or court order for the person or entity committing the wrongful act to stop a certain behavior or action. A person who commits a tort is known as a tortfeasor.

A toxic tort is a tort that involves exposure to harmful pharmaceuticals, chemicals, solvents, substances, gases, mold, or other materials, causing personal injuries and requiring medical treatment. Examples of toxic tort claims include exposure to asbestos-containing products, pesticides, lead-based paint, tobacco, and hazardous waste materials (such as those used by dry cleaners).

Toxic torts are often associated with personal injury claims, as many toxic torts can cause personal injuries. These claims and the related law are sometimes broadly referred to as toxic tort law.

In Wyoming, a tort is recognized as a civil wrong that can result in the tortfeasor (the person who commits the tort) being held liable for damages. Toxic torts specifically deal with injuries caused by exposure to harmful substances. Wyoming follows the general principles of tort law, which require the plaintiff to prove that the tortfeasor owed a duty of care, breached that duty, and caused damages as a result of the breach. In the case of toxic torts, claimants must typically show that exposure to a toxic substance was the cause of their injury. This often involves complex scientific evidence and expert testimony. Wyoming statutes and case law would govern the specifics of any toxic tort claim, including the statute of limitations for filing the claim, the standard of proof required, and any caps on damages. Federal laws, such as environmental regulations and workplace safety standards, may also play a role in toxic tort cases, particularly when the exposure is related to a regulated substance or industry.
