Formula One’s governing body has uncovered the causes of the Romain Grosjean fireball crash at last year’s Bahrain Grand Prix and outlined areas for improving driver safety.
A Swiss-born French driver crashed on the opening lap of Bahrain on November 29, when he hit a barrier 180 meters from the top of Turn 3. Grojan Grojan’s car was running at 241 km / h when it lost control. When trying to pass from the left side to the right side of the truck, turn 3 ends after the right rear wheel and the left front wheel of Daniel Kviat come into contact.
The contact lifted the French driver’s car and collided with the triple guardrail barrier behind the run-off area at a 29 degree angle at 192 km / h. There is an estimated yaw of 22 degrees with respect to the direction of travel, and the resulting peak forces are comparable. Up to 67g.The effects of high energy saw him Haas F1 Team The powertrain assembly was separated from the survival cell while the car ignited.
The Geneva-born driver was able to get out of the car on his own, and 27 seconds later he got out of Haas’s machine. Grosjean suffered burns on the back of his hands.
“The arrival of FIA F1 Medical Rescue Coordinator Dr. Ian Roberts, FIA F1 Medical Car Driver Alan van der Melwe, and a medical car with a local doctor immediately showed that each was playing a pre-determined role. I helped. “
“Ian Roberts immediately went to the scene of the incident and instructed the Marshal to operate a dry powder fire extinguisher around the cockpit, where he told Romain Grosjean that he was trying to make his exit. Confirmed. Alan van der Melwe recovered the fire extinguisher from the rear of the FIA medical car while a local doctor was preparing a trauma bag, “read the statement.
FIA President Jean Todt said: The FIA’s lasting efforts to reduce the risks associated with motorsport, especially the safety sector, have helped Romain Grosjean stay conscious and survive an accident of this magnitude. Safety is a top priority of the FIA and will not change in the future. “
Regarding the investigation, FIA safety officer Adam Baker said:
“The efforts of the people involved are heroic and, of course, have received a lot of praise. Following the approval of the findings by the World Motor Sport Council, we have integrated our actions into the work in progress. To do.”

As a result of the investigation, the FIA has outlined a total of 22 areas where driver safety can be improved, including changes to fuel hatches, footwells and headrests. Here is a complete list of areas that the FIA will work on:
-Adjusting the front shape of the survival cell and additional load testing in that area
-Review of existing regulations on rearview mirrors
-Review of steering column mounting requirements
-Review of headrest assembly regulation and homologation requirements
-Power unit installation and installation failure mode analysis
-Ongoing research project: Wheel restraint cable (tether)
-Design review of safety fuel bladder installations in all FIA single-seater categories
-Best practices for safety fuel bladder installation recommendations
-Updated FIA standards for safety fuel bladder
-Regulatory review of safety fuel bladder connections and inspection hatch design
-Fuel homologation including compatibility of bladder materials with specific fuels
-Improved circuit safety analysis software (CSAS) capabilities, including quantitative impact probability classification
-Review of installation of existing circuit barrier openings
-Circuit homologation and license renewal guidelines / process reviews
Driver safety device
-Survey on improved heat transfer coefficient (HTI) of gloves
-Ongoing research project: Visor opening and closing mechanism.The scope of the project has been expanded to include requirements to ensure that the visor opening system works after being exposed to fire.
-Ongoing research project: Fire extinguisher system for open cockpit cars.The scope of the project has been expanded to include research on improved activation mechanisms.
Medical and rescue
-Updated medical intervention vehicle equipment, including alternative fire extinguisher types
-Provide ASN guidance on post-fire decontamination
-Continuous development of FIA fire drill modules for ASN
-Continuous development of FIA high voltage safety training module for ASN
-Continuous development of FIA incident command / coordination training module for ASN
In addition, the FIA Safety Department is planning further research projects such as:
-Investigation of options for proximity warning systems and electronic visibility aids-Study of modification and upgrade options to improve the impact performance of existing guardrail barriers
-Research on new barrier systems that are effective in a wider range of impact conditions
-Research to evaluate current fire extinguishing media, fire extinguishing equipment, personal protective equipment and evaluate new technologies
