Williams published a statement that one team member had suffered burns and remained in hospital in Spain.
“He is stable and will return to the UK within the next 48 hours to receive further medical care,” the team said.
“His family are in constant communication and he is in good spirits.”
Two others had been released and returned home to Britain from Barcelona after receiving treatment for smoke inhalation.
FIA said on Sunday that seven F1 staff were taken to hospital and 31 tended to by doctors. Williams give the thanks for all helping people, from rival teams and other areas of the paddock and all helped put out the fire and investigations into the cause of it were ongoing.
“I was pleased to welcome back to the factory the majority of our team this morning,” said the 70-year-old principal, who added that the damage was “relatively speaking” limited.
“While the incident was unexpected and definitely most undesirable, it has demonstrated the genuine cohesiveness, camaraderie and spirit of co-operation that exists within the Formula One paddock,” he added.
“The astonishing response from the teams and other paddock personnel was immediate, unconditional and overwhelming.”
