A group isolation system is an efficient method of isolating multiple energy sources prior to maintenance or repairs commencing. In a group isolation, a person known as an authorised isolator would isolate all the energy sources with a keyed alike set of safety padlocks (often yellow in colour). The isolations would be verified by a second person. Once all the energy sources have been isolated, the authorised isolator places the key to the yellow safety padlocks inside a Group Lock Box and then places his or her safety padlock on the outside of the box.
