I posted this in another thread:
I do wonder (and I'm only speculating) if the fire marshal crossed the track as a result of new procedures following the F2 accident in Sochi where it took quite some time for fire marshals to get to Luca Ghiotto's burning car on the other side of the track. After that race, Michael Masi said the fire marshals had to wait until the race was red-flagged. However, in the Portuguese GP four weeks later, fire marshals could be seen crossing the track without a red flag.
In Sochi, the nearest marshal post on drivers' right was 150 metres away from the burning car. There was a marshal post nearby but on the other side of the track.
A couple of videos I found from Sochi (a fire truck with more marshals and extinguishers arrived after the second video ended):
Here's a short video that shows the fire marshal (singular?) crossing the track from the marshal post on drivers' left to get to Ghiotto's burning car. https://youtu.be/UvnmNZ9SLaE
This was at least 1:45 minutes after the impact.
And here's a longer video showing Ghiotto walking away from the accident and the medical car. And the single fire marshal. As the camera pans back the fire marshal has left and probably crossed the track. https://ren.tv/news/...ossii-formuly-2
No ambulance or other vehicle than the medical car was to be seen, so I guess Ghiotto walked to the marshal post 150 metres away, the one that Michael Masi wouldn't want to be running from with a fire extinguisher.
Some more details on marshal posts etc:
