Mechanical safety devices are tools or systems designed to prevent accidents and injuries in various environments, such as workplaces and homes. These devices can include items like safety guards, emergency stop buttons, and interlock systems, which help ensure that machinery operates safely and that users are protected from potential hazards. These devices work by either physically blocking access to dangerous areas or by automatically shutting down equipment when unsafe conditions are detected. By incorporating mechanical safety devices, organizations can enhance workplace safety, reduce the risk of accidents, and comply with safety regulations.
