Three McLaren mechanics have been treated for injuries after a fire broke out in the British team's garage.
McLaren were taking part in a private filming day at Barcelona's Circuit de Catalunya when the incident occurred this afternoon.
The trio were swiftly taken to the on-track medical centre to be examined where it is understood they received medical care for slight burns.
"There was a small fire in the garage during the team's private filming day," said a McLaren spokesperson.
"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 released shortly after."
It is unclear how the fire started at this stage, although the British team have launched an investigation to identify the cause of the blaze.
Formula One's teams have this week been in Barcelona testing, and McLaren had stayed on to conduct a filming day with both British teenager Lando Norris, and his team-mate Carlos Sainz, on driving duties.
In 2012, a fire broke out in the Williams garage at the same venue in the moments after the Spanish Grand Prix. People were injured in the incident, although none seriously.
