The area around the motorhome was cordoned off, with ambulances and the fire service surrounding the motorhome as smoke continues to linger in the hospitality unit.
A statement from the team read: "This morning we evacuated our Team Hub paddock hospitality unit following a fire alert, the team has been safely evacuated while the local fire brigade handle the issue."
The fire was reportedly difficult to put out, with Pirelli chief Mario Isola, also a part time paramedic, helping with the efforts to extinguish the blaze.
Lando Norris told the media that his race suits were inside the motorhome, but his FP3 session was not delayed.
