That was my concern following on from above, what if some idiot attempted to ignite such a large flag gliding over thousands of heads prior to kick off with a lighter, if the flag wasnt certified "fire retardant"goodness knows what chaos/ injuries it could cause.
I would have thought it was in the best interests of the club, as part of their fire risk assessment to ensure that if they let such a potential fire hazard free inside their stadium, they would ensure all safety aspects/ control measures as well were addressed, as I wouldnt be surprised that whoever provides the flag aint thinking about it being a fire hazard, instead just a bit of harmless fun.
But that didnt concern the police at a meeting I attended at the start of this season, it was as I mentioned above, they wanted the flag banned as there could have been a crime being committed underneath that they couldnt see.
