Extinguishers
J20.14.7 Vehicles of Period A to F be equipped with a fire extinguisher in accordance with Q.3.1.2(b) [Medium, Hand Operated, for discharge into both cockpit and engine compartment]. Other vehicles to be equipped with a fire extinguisher in accordance with Q 3.1.2 (a) [Medium, plumbed in, for discharge into both cockpit and engine compartment]
The reason given for the change as regards extinguishers:
"Increasingly the number of marshals stationed on post at race circuits is diminishing. It is thus considered appropraite for vehicles to be equipped with some basic "first aid" fire fighting capability. It is to be noted that most, if not all FIA formulae require vehicles to be equipped with fire extinguishers".
"Note: recommended from 1 January 2005, mandatory from 1 January 2006"
Hope this helps you all
