Williams's celebrations at their first Formula 1 victory in eight years have been marred by a fire in the team's garage at the Spanish Grand Prix.
A Williams mechanic suffered minor injuries and a Force India mechanic with smoke inhalation is being treated at the Barcelona track's medical unit.
BBC Sport understands that some Caterham mechanics were also hurt but the team has so far refused to comment.
The incident is believed to involve a Kers unit, which sparked a fuel fire.
Force India deputy team principal Bob Fernley told BBC Sport that his team member was okay.
"Thanks for your best wishes to the team member who bravely went to fight the flames. He is being checked out in the circuit medical centre," read a Force India tweet.
The fire occurred after Williams's group photo commemorating Pastor Maldonado's victory., the Grove-based team's first since Juan Pablo Montoya's win in the 2004 Brazil Grand Prix.
