Mike,
I was rather concerned to see that your guidelines for "Jingle Bells" do not mention the need for everyone to wash their hands after the sleigh ride - obviouly ther risks of contacting E-coli are quite high.

Goggles should be worn by passengers at all times, due to the risk of grit etc. being kicked up by the horse.

There is also the problem of the bells constantly jingling and causing both a noise nuisance to the surrounding area , and distress to the horse.

If the sleigh is to carry children, the driver should have undergone a full CRB check.Teachers should ensure they have carried out a full risk assessment which includes details such as the appropriate clothing to wear,how to walk up to the sleigh, staffing and of course the safest method to climb into and out of the sleigh. It would be appropriate to have a full safety briefing, and perhaps a parents meeting beforehand.A full first aid kit should be carried by each teacher, along with a list of parent contact numbers and of course a mobile 'phone. They should also have a list of pupils with specific allergies etc.They should have produced a detailed lesson plan, stating the learning objectives and differeniated outcomes.Obviously the learning experience will be assessed back at school.

Public liability insurance certificates should be available for checking.

I hope this is of use.
