The FIA has taken immediate action in the wake of the accident involving a Formula One Management cameraman during Sunday's German Grand Prix.
The governing body announced on Tuesday evening that it would move to tighten safety by limiting pitlane access during grands prix and qualifying sessions to team personnel and marshals only.
It will also use the World Motor Sport Council to immediately approve two amendments to the Sporting Regulations.
The change to Article 23.11 means that all team personnel working on a car during pit stops will require head protection, while the amended Article 30.12 will reduce the pitlane speed limit during races from 100 km/h to 80 km/h. For the street circuits in Melbourne, Monaco and Singapore, the speed limit will remain 60 km/h.
These two amendments were already set to come into practice next season, but Sunday's accident has led to them being brought forward by the FIA "on the initiative of its President, Jean Todt".
Cameraman Paul Allen suffered a broken collarbone and ribs after being hit by a wheel which had worked loose from Mark Webber's Red Bull following a pit stop on lap eight of the race.
The World Champions were subsequently fined €30,000 for an unsafe pit release.
The FIA added that it "is expecting a written report from Red Bull Racing tomorrow. This will also be shared with the other teams in order to help improve pit lane safety".
