Sugestion: if you get a form with TWO sets of ICE (In Case of Emergency — it's a thing, trust me) list him as #1 and your mom as #2.

Also, add his phone number on your contacts as "ICE" so that the first responders know whom to call when they find your unconscious body. Do the same thing with the Emergency Contact info on your phone (this will differ based on brand and OS). If the responders call, it will be from your phone, so he'll answer.
