In American football, a safety is a scoring play that occurs when the offensive team is tackled in their own end zone, or if they commit a penalty in that area. A safety is worth two points and can significantly impact the game's momentum. Safeties can also refer to safety devices in various contexts, such as fire alarms or safety goggles, which are designed to protect individuals from harm. These devices are essential in ensuring safety in workplaces, homes, and during activities that pose risks, helping to prevent accidents and injuries.
