Three McLaren team members received medical attention on site at the Circuit de Barcelona-Catalunya as a small fire broke out in the team's garage.

While the first pre-season test at the Spanish circuit ended on Thursday, several outfits have remained to conduct 100km filming days as permitted by the regulations.

Williams and Racing Point were among the others also present at the track, however, were unaffected by the incident.

"There was a small fire in the garage during the team's private filming day," a spokesman for McLaren told Formula1.com

"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.”

While there was no news on what caused the fire, McLaren is having to assess the damage caused to their equipment with only three more days until the second test begins in Barcelona on February 26.
