Loto
I am in charge of creating the first loto placards my facility has ever had.
I have limited experience with it and we have very complex systems since we are aluminum melting and casting facility and our machines have lots of potential loto points. In addition to alternative protections , minor servicing , safety plc, and commonly use group loto.
My plan is to make placard that shows all loto points for a machine. Then Have work instructions for every task. The work instructions will designate what loto points you need for your task.
I’m getting hung up on the designations. When I label e-1 , this means that other higher electrical disconnects ( E-2 or E-4 ) are in the same circuit and e-1 should kill it.
This got hairy when I had multiple E-1s
However my issue now is how do I label gravity , water , ect.
I’m using g for gravity but Does gravity not get G-1 and G-2 since they’re not a circuit ? Or in that scenario since it’s not electricity do i label it differently ?
Nothing about this is in the ANSI.
Additionally do I need to specify how to verify the machine is safe? Or just state in general to do it ?

To answer the last question I would include the steps of "The Application of Control" in your template. Verification is without a doubt one of those steps and how it is done on that machine.
As far as the rest of your questions plenty of templates on line and to be purchased. There is also software available. If you have many to do, I sure would recommend that. Brady had a nice package and I an sure there are others! It was very reasonable priced. In my last job before becoming a consultant we had a Corporate Template we had to follow. If you have a Corporate EHS Department call then for help. That's why they are there!
You can also reach out to your other EHS contacts. That is the importance of networking. You are in much greater detail than I ever used. Remember these are for your average employees to use, not Engineers. My $.02
Example I have on hand I can get better tomorrow
Here’s an example of several gravity locks. I think it gets weird when E1 kills E2,3,and 4 but g 1 through 4 obviously are independent .
