I read recently the post about fire extinguishers needing to have the clamps changed and be larger size. Where does this come from? The blue-book?

I saw that too. I think its App J. Worth a look.

Article 7 here:

It seems it is a new FIA requirement for plumbed in systems. The safety instructions from the RACB (the Belgian ASN) for the Spa Summer Classic specifically identify it as a requirement for this year - but it will undoubtably spread. All designed to catch us out at scrutineering.

I have just ordered two retaining straps for the princely sum of £4.56 +VAT - the carriage is more than the cost of the straps......

The normal size sold in the UK of 2.25 ltr is still OK - the RACB have amended their original statement of needing 2.4 ltr.

Where are they from Brian?

**Peter Mallett** · 17 May 2011, 10:05 (Ref:2881510)

As above Terry. Appendix J.

BTW. As I read it AFFF is 2.4lt and all others are 2lt.

Errrrr,I was referring to the straps Peter.

They are from a fastener specialist found when searching for Mikalor clamps. I've ordered what they describe as T-bolt hose clamps - come in all sorts of sizes. www.hcl-clamping.co.uk.

You may want to wait until they've arrived and I can confirm that they work

terence · 17 May 2011, 10:28 (Ref:2881517)

Tweeks do them for the same money Brian,thankyou. Just ordered mine but there has been a rush on them [no,really?] £17.25 with post and packing.

[Suppose I ought to make it totally legal before I sell it.]

My reading of the regs is that App K 5.7.1 says that circuit cars must be equipped with at least a hand operated (manual) extinguisher complying with App J 253.7.3 (;ast updated 8 Marc 2011) but a system homolgated by the FIA per 253.7.2 (referring to Tech List 16 -recommended systems - last updated 10 Sept 2010) is recommended.

This can be taken to mean that an approved Tech List 16 system is preferred but a 253.7.3 hand held manual is a minimum (ie, both are not required).

Looking at 253.7.3, at 7.3.3, it says that manual extinguishers must have various minimum capacities (eg AFFF, 2.4l). It actually says 'Minimum quantity of extinguishant' and then lists them, but this is para 7.3.3 and therefore as a subclause to 7.3 must only apply to 7.3 which is headed 'Manual extinguishers', as opposed to para 7.2 which is headed 'Systems mounted' and therefore applies to mounted (and not manual) extinguishers.

This analysis is confimed (in my mind at least) by para 7.3.6 which says that they must withstand 25g deceleration force, and this requirement is repeated in para 7.2 2. The former requirement therefore only applies to 7.3 (manual) extinguishers because the latter requirement has already applied to 7.2 (mounted) extinguishers.

Ipso facto, para 7.3.3 only applies to 7.3 (manual) ectinguishers.

The upshot of all this is that, for circuit races, a Tech List 16 approved system (eg Lifeline Zero 2000 homologated system) remains acceptable.

I think.

Jeremy, do you agree with this analysis please?

Surely you mean "rue" otherwise be careful what you wish for.

Just to update this the current App K regs are here: http://argent.fia.com/web/fia-public.nsf/5BE6AD18AB4AAEC4C125796E00489DE5/$FILE/2012_Annexe%20K_09.12.2011.pdf

Appendix K 5.3.1
"If the battery is retained in the cockpit, it must be the dry type, be securely fixed, and have an insulated, leak proof cover."
Does this mean that all batteries that are in the cockpit have to be in a sealed battery box? Does anybody have any experience of this?

terence · 14 Mar 2012, 07:59 (Ref:3040783)

Always best to put them into a box,in case they break loose,but I think you'll find that it should be anyway.

Mike Bell · 14 Mar 2012, 10:43 (Ref:3040859)

Agree with that but not sure if all series require it. The Porsche Drivers Assoc regs insist the cars have batteries in 'sealed' boxes, but then see cars in other champs with battery open. My hist FF2000 for example does not have enclosed. App K cars obviously will need to comply with those requirements....
