Australian Formula One Grand Prix organisers have detailed safety improvements for 2002 after the death of a marshal at this year's season-opener.
An enquiry will open in Melbourne on December 3rd into the March 4th death of 52-year-old Graham Beveridge, the marshal who was hit by debris after a collision between Jacques Villeneuve and Ralf Schumacher.
The governing International Automobile Federation (FIA) has said that it considers the fatality to have been a freak accident.
Beveridge died when a wheel struck him after punching through a narrow aperture in the fencing.
The FIA has made next year's race conditional on the outcome of the enquiry.
"Since the 2001 event, an extensive review has again been done of Australian Grand Prix safety fences and certain changes are proposed for 2002," the official grand prix website said.
"It is proposed to revise the openings in the fences around the 5.3 km circuit and to reduce their number," it said.
The proposals, approved by the FIA, will be presented to the coroner.
The organisers said the current openings in fences would be replaced by two new specially designed types "with emphasis on minimising the risk of penetration by debris".
One type would face away from the direction of traffic while the other will be a "smaller climb-through opening" with a protective cage behind.
Openings in the fences for media photographers and television cameras will also be changed.
