Liability waivers are documents that participants sign before engaging in an activity, stating that they will not hold the facility responsible if they get injured. These waivers have been commonly used by gyms, amusement parks, sports centers, and other recreational venues to protect themselves from lawsuits, even if the injury was due to the facility's negligence. Negligence occurs when a facility fails to provide a safe environment, such as not maintaining equipment properly, not having adequate safety measures in place, or failing to provide necessary supervision.
