Should I wake up a paramedic who is on shift?

I need to know whether I should wake up a paramedic who’s currently on shift. I got to the gym at 2:20AM and there was an ambulance car already in the car park with its running lights on (not blue lights). I left at 4:10AM and it was still there and as I was driving out I saw the paramedic in the car was asleep. I’m currently grabbing a meal but will be driving past the gym again, if the car is still there should I wake up the paramedic? I’m worried he’s fallen asleep and missed an alarm or something but equally it could just be a quiet night. I live in a decently sized town (~60k people) in NW England too if that context could help
