The 1981 Belgian Grand Prix was a Formula One motor race held at Zolder on 17 May 1981. It was the fifth race of the 1981 Formula One World Championship. It was the last of 12 victories for Carlos Reutemann and the last win for an Argentine driver . It was also the first of 59 podiums for 1992 World Champion Nigel Mansell. Mechanic safety and chaotic first race The race was marred by two serious incidents involving mechanics, one fatal. In Friday practice a mechanic from the Osella team, Giovanni Amadeo, stumbled off the pitwall into the path of the Williams of Carlos Reutemann. Reutemann was unable to avoid the mechanic, who suffered a fractured skull. He died from his injuries on the Monday after the race. Before the start of the race the mechanics of all the teams staged a protest over the safety measures protecting them, which was soon joined by several drivers (Villeneuve, Prost, Laffite, Pironi and Scheckter) who left their cars.

The resulting chaos when the grid formed up again at the end of this lap was exacerbated when Nelson Piquet missed his starting position and was sent round on another lap, with the other cars being held in position. As the cars began to overheat, several drivers turned off their engines, among them Arrows driver Riccardo Patrese, expecting another formation lap due to Piquet's error. However, the organisers began the start sequence as usual once Piquet had regained his position. Patrese was unable to restart his car and waved his arms to signal that he could not take the start. His mechanic, Dave Luckett, came onto the track to restart the car from behind. As he did so, the Clerk of the Course had already started the lighting sequence to start the race, and the race went ahead despite his presence and Patrese's gesticulations. The other Arrows driver, Siegfried Stohr, ploughed into the back of
