The Risk Asst might be required to help you get some funding, but it is the organisation who needs it themselves, really. It is there so that, should something go wrong, and person / people get injured, you can demonstrate that you have done what you can to ensure that the place / event was safe and that you considered all hazards and did what you could you mitigate them. Don't know what type of event it is you are organising, but you may need to consider the different areas you are operating - eg areas where there is potential conflict between pedestrians and moving vehicles - what can you to lessen the risk of people being run over? Are there any areas of open water? What can you do to lessen the risk of people falling in? If somebody does fall in, how would you get them out? Do your marquees have guy ropes which people can trip over? What First Aid provision do you have and how would people access First Aid if required? What specialist equipment do you provide litter pickers, in case they have to deal with sharps / broken glass / hazardous sunstances?

Whilst other organisations might ask you to provide evidence of your risk assessment in order to issue a license / give permission for the event to take place on their land / in their building etc, or to confirm award of a grant, at the end of the day, it is the organiser who needs the risk assessment - to show that risks have been considered. If something goes wrong and someone ends up in court, it is difficult to say - oh, we considered that risk and did such and such about it - with no evidence.

Oh - and a risk assessment should also be signed and dated ... and the 'crew' should all sign to say they have read it and are aware of its contents etc ....
