In a schematic diagram, where are the safety controls typically located?

In a schematic diagram, safety controls are typically positioned to the left of the loads. This placement is significant because it allows for a logical flow of operation, where safety devices can intervene before the process reaches the load. Safety controls are designed to monitor the operation and ensure safe functionality, hence their placement in the schematic emphasizes their role as protective measures. By being to the left, it visually represents that they operate before any potential hazards arise from the loads themselves, allowing technicians to easily identify and troubleshoot safety components in an emergency or during routine maintenance. This arrangement is grounded in standard practices for electrical and gas systems, where safety is prioritized and distinctively laid out in the diagrams for clarity and safety in design and operation.
