In our computer room we have an emergency stop button, with a clear plastic case velcroed around it. It's clearly visible, clearly marked for what it is, and anyone with a bit of sense will realize that you pull the cover out of the way and press the button.can you put a shroud or guard around a palm type or mushroom style e-stop? nfpa 79 10.7.1 simply states it is needs to be readily accessible. who has dealt with this? thanks in advance.
