The FIA recently released the latest edition of the FIA Safety Bulletin which focused on the updated guidelines for single-seat driver extrication. This includes the removal of the requirement to extricate the driver in the extractable seat.
The article provides more suitable ways to extricate a driver including:
Self-Extrication
Drivers who are uninjured or unable to get out of the car unaided may do so even in the event of high g-force accidents due to the advanced safety measures that have now been implemented. This may be done under the supervision of the attending medical staff with their guidance if needed.
Boa Device Extrication
This device is passed around the neck of the driver (who may be wearing a c-collar) and under the arms to allow the driver to be lifted from above and behind. The device pulls tight enough under traction to stabilise the upper spine while not impeding respiration and can assist with rapid, controlled extrication out of the vehicle.
Watch the Boa device method here.
Short-board Extrication
This device (Ferno XT or similar) is inserted behind the driver in the seat. The driver is strapped quickly to the device around the chest and head with lifting handles on the device to allow quick and safe guided extraction of the driver from the seat and onto a board or vacuum mattress.
Watch the short-board method here.
Rapid Extrication
If the driver is facing an immediate danger to life, such as a significant vehicle fire, a hazardous situation or a major injury requiring immediate treatment, rescuers may use the grab handles on the racing suit while managing c-spine inline stabilisation to remove the driver from the vehicle rapidly.
Watch the rapid method here.
Further guidance on extrication can be found in FIA ISC Appendix H Supplement 7.
