Specifications

Article 33: Engine and Fuel System Isolation from the Driver
• A permanent Bulkhead must completely separate the vehicle’s
propulsion and energy storage systems from the driver’s
compartment.
This means engines, fuel cells, fuel tanks, batteries, hydrogen
cylinders, super capacitors, etc. must be placed outside the driver’s
compartment behind the bulk head. The purpose of this bulkhead is
that in the event of a fuel leak or fire, it prevents liquids and / or
flames and / or smoke reaching the driver. Therefore, it is necessary
to pay particular attention to avoid any gaps and holes between the
body and the bulk head. It is recommend to seal gaps with materials
such as metal / aluminium sheeting or aluminium tape.
• This bulkhead must be of fire retardant material and construction.
• In closed-top vehicles the bulkhead must effectively seal the driver’s
compartment from the propulsion and fuel system.
• In open vehicles the bulkhead must extend at least 5cm above the highest
point of the propulsion and fuel system or the driver’s shoulders – whichever
is the highest.
• The bulkhead must prevent manual access to the engine / energy
compartment by the driver.
Article 34: Horn
Each vehicle must be equipped with the authorised horn that can be purchased
from the organiser.
Article 35: On-board Fire Extinguisher
• Each vehicle must be fitted with a fire extinguisher (ABC or BC type). All
Drivers must be trained in the use of said fire extinguisher. This extinguisher
must have a minimum extinguishant capacity of 1kg (2lb for US application),
equivalent size extinguishers are not permitted. It must be full and have a
certificate of validity bearing the manufacturer's number, the date of
manufacture, and the expiry date.
• Plumbed-in extinguishers may be located in the engine compartment and
must discharge into the engine compartment. Triggering systems must be
located within the cockpit and be operable by the Driver in his/her normal
driving position.
• Hand held extinguishers must be located within the cockpit and be
accessible to the Driver once they have vacated the vehicle. These should
be securely mounted to prevent movement while driving/braking. In the
event of a fire, Drivers should first exit the vehicle and then if possible,
remove the extinguisher and attempt to extinguish the fire if safe to do so.
• The on-board fire extinguisher does not replace the need for an adequate
fire extinguisher for the teams garage area.
