5 seconds added time for having the car on the jacks when the the others leave for the warmup lap. It was dangerous and they kept working on the car in traffic. I was certain there would have been a stop & go or at least a DT, but instead he got 5s extra stop time during a regular pit stop. It also took the stewards almost half an hour to come up with that decision.
There was a similar incident a while ago, but my memories of it are not detailed enough to remember who was standing on the jacks and where it was. Neither do I remember the penalty so I have not much to Google. Anyone that has a better memory?
EDIT: Nonesuch found the paragraph:
38.5 When the one minute signal is shown, engines should be started and all team personnel must leave the grid by the time the 15 second signal is given taking all equipment with them. If any driver needs assistance after the 15 second signal he must raise his arm and, when the remainder of the cars able to do so have left the grid, marshals will be instructed to push the car into the pit lane. In this case, marshals with yellow flags will stand beside any car (or cars) concerned to warn drivers behind.
