Three McLaren Formula 1 team members have been given medical treatment after a fire occurred in the squad's garage at the Barcelona circuit.
Along with Racing Point and Williams, McLaren had been running its new MCL34 machine as part of filming day on Friday.
The filming including some laps in conjunction with a papaya-coloured McLaren road car.
After the incident, the team released a statement regarding the fire that read: "There was a small fire in the garage during the team's private filming day.
"The fire was quickly extinguished by the team, and circuit emergency services and medical teams attended immediately in support.
"Three team members were taken to the medical centre for treatment and were released shortly after."
McLaren has not released any more details of what occurred.
Barcelona was also the scene of the major fire in the Williams garage shortly after Pastor Maldonado's victory in the 2012 Spanish Grand Prix.
That incident led the FIA to mandate the use of protective equipment and dry-break couplings for garage refuelling.
In a change to the Sporting Regulations for 2019, the FIA has insisted that the same precautions are now also in place for testing.
This change came after observers noted that some teams were not always following the race weekend procedures.
