Check out the list of Christmas "myths" (or rather complete porkies and distortions) about health and safety. This "Top 10" list was compiled by the Health and Safety Executive (HSE).
The same old (dare I say) chestnuts are here - such as children being banned from having snowball fights and carol singers being classified as a health and safety risk. This is indeed a load of old nonsense but this has nothing to do with safety regulations. Some organisations just use 'elf n' safety as an excuse. While many Tory politicians and their media just make things up about safety issues in order to make cheap political points.
If trivialising health and safety wasn't such a serious issue you would be amused by the attempt of the Daily Telegraph who covered the story here as some sort of attack on "health and safety killjoys" yet completely missing the point that the problem is not the safety regulations but myth making and grossly inaccurate reporting by...(amongst many others)... The Daily Telegraph. See their coverage here of Brownies being banned from carol singing. Never mind the rubbish put out by its political stable mate the Daily Mail.
Finally check out this piece of common sense written last year by IOSH Chair, Rob Strange.
