Electrical interlocks are safety devices that prevent machinery from operating under unsafe conditions, ensuring that certain electrical circuits are only activated when specific conditions are met. Mechanical interlocks, on the other hand, are physical mechanisms that prevent the operation of equipment unless certain conditions are satisfied, often used in conjunction with electrical systems for enhanced safety. Both types of interlocks are essential in industrial applications to protect personnel and equipment from hazards. Understanding their functionalities allows for better implementation in safety protocols and operational procedures. Proper utilization of interlocks can significantly reduce the risk of accidents in various engineering environments.
