In the 2000 Italian Grand Prix, Gislimberti was working for CEA Squadra Corse at Monza. Before the start of the race, he moved further up from his post, taking his fire extinguisher with him. During the first lap of the race, Gislimberti had stopped for a brief moment after running back to check on his fire-fighting equipment, as a multiple-car accident at the Variante della Roggia corner sent a wheel from Heinz-Harald Frentzen's Jordan flying, striking Gislimberti with full force, leading to massive head and chest injuries. His red helmet came loose and rolled towards the side of the track. Another firefighter standing next to Gislimberti attempted to save his life before medical help from Sid Watkins and Gary Hartstein arrived on the scene. He was taken to the First Aid Room at Monza Hospital where he was pronounced dead. Gislimberti's death was the first Formula One related fatality since the death of Ayrton Senna in the 1994 San Marino Grand Prix, and the first for a bystander since Team Osella mechanic Giovanni Amadeo was killed in the pitlane at Zolder in May 1981. An autopsy reported that Gislimberti also suffered from cardiac arrest when he was struck by the wheel of Frentzen's car. He was survived by his pregnant wife of two years, Elena, who had a daughter named Lisa born in December 2000, and has received financial help from the Formula One community via a fund. His parents, two brothers and sister also outlived him. Bernie Ecclestone donated $40,000 and the teams donated $10,000 with the drivers holding an auction to sell their overalls used in the 2000 United States Grand Prix.
