When can internal activities in manufacturing be performed?

Internal activities in manufacturing refer to tasks that can only be performed when the machine is stopped, such as maintenance, setup, or changeovers. This is because these activities typically pose safety risks if performed while the machinery is operating. When the machine is not running, there is no risk of sudden movements or other hazards, allowing personnel to conduct their work safely and efficiently. Furthermore, proper execution of internal activities can improve the overall productivity and reliability of manufacturing processes by ensuring that equipment is well-maintained and ready for operation once it is powered back on.
