8. Fit and Security: 8.1. To ensure satisfactory fit and security of your helmet proceed as follows:
a. Obtain correct size by measuring the crown of your head. b.
c.
d.
Check that there is no side-to-side movement; a helmet should be as closely fitting as possible consistent with comfort.
Tighten straps securely – the chin strap must always be in tension; ensure therefore that the strap cannot slip. Chin cups are prohibited.
With head forward attempt to pull up the back of the helmet to ensure the helmet cannot be removed in this way.
e. Ensure you can see clearly over each shoulder. f.
Make sure nothing impedes your breathing in the helmet and never cover your nose or mouth other than with a flame-resistant balaclava or face mask.
g. |
Helmets with life-support must only be worn if connected to a permitted life-support system. |
h. |
Never wear a scarf tie or other loose clothing which could come loose and possibly cause an accident. |
i. |
Ensure that the visor can be opened with one gloved hand. |
j. |
Satisfy yourself that the back of the helmet provides protection for your neck. |
k.
Do not buy from mail order unless you can satisfactorily carry out the above checks; return a helmet unused if it does not fit.
9. Condition and Care of Helmet
9.1. The user must bear the prime responsibility for ensuring that the helmet is fit for the purpose intended since significant damage to the helmet may have been sustained without this being apparent to the Scrutineer.
9.2. Anything other than minor superficial damage is likely to result in the Scrutineer removing the ASN sticker and impounding the helmet for the Event.
9.3. It is in everyone’ s interest for the Competitor to buy the best helmet possible and to look after it( the best is not necessarily the most expensive). A helmet bag should always be used.
9.4. There must be no alteration to the structure of a helmet. Where a radio intercom is fitted this should only be done in accordance with the helmet manufacturer’ s instructions. Fitment of cameras to helmets by whatever means is not permitted unless an integral camera is provided by the helmet manufacturer and that model of helmet is approved under one of the accepted standards.
9.5. Use only a weak solution of soft soap and water to clean the interior and exterior of the helmet; do not get the interior too wet.
9.6. Some moulded plastic helmets although they meet approved standards can be seriously damaged by substances such as petrol paint adhesives cleaning agents and stickers( not the ASN stickers) – such damage may not always be apparent; however crazing or obvious dulling of the surface finish could indicate serious structural weakening of the helmet and is likely to result in the Scrutineer removing the ASN sticker and impounding the helmet for the Event.
