Add an Emergency Stop Button
It is essential to have safety devices such as emergency stop buttons (or more commonly called the E-Stop buttons) installed on machines such as lathes, milling machines, or even drill presses.
We would highly recommend reading Doug Nix’s article, “Emergency Stop – What’s so confusing about that?” where he goes into detail about what an E-Stop is and what it does.
You should add a standardized E-Stop button on every machine. Yes, Ferndale Safety even recommends installing these buttons on drill presses and bench grinders. Why? A standard twist-release E-stop button with a yellow background should be recognizable by anybody working in an industrial setting near machinery. Some machines have many buttons that, over time, have had their identification labels rubbed off. If an emergency occurs where a person that is not familiar with the device needs to shut it down, an E-stop button that is within reach and visible can be the one thing that saves the day.
Where to Install an E-Stop?
Install emergency stop buttons within easy reach of where the operator would need to be. Think of places such as cleanout doors, chip conveyors, or behind machines. You should have one everywhere where an operator might be. For smaller tools, just one e-stop is sufficient.
Installation & Precautions
Below is an example diagram of where you could wire an E-Stop into a standard machine tool such as a drill press. Note: Don’t install these buttons directly in series with the motor circuit. It must be installed only in series with the control circuit.Each e-stop comes with one normally closed contact.
