The band will be the first act to play at London's O2 Arena ceremony tomorrow night (February 21) and have had health and safety officers worried about the amount of pyrotechnics they are using for the set.
A source told The Sun: "It has been a logistical nightmare and for a long time organisers didn't think they'd be able to go ahead with the plans.
"People have been running around the arena with clipboards for weeks trying to sort it out."
Meanwhile, James Corden - who will host the event - told Xfm: "The show is going to be incredible. Coldplay are opening, which will be huge. They have spent a fortune on pyrotechnics to make it something really special.
"Blur will perform for 11 minutes at the end of the show - more than anyone has been given before for the 'Outstanding Contribution To Music Award'. Add Adele, Ed Sheeran and Noel Gallagher and you've got an incredible lineup."
Coldplay are up for the 'British Group' and 'Mastercard British Album Of The Year' awards at the ceremony, but have insisted that they will not win any of their categories.
