All booth Tents and Canopies MUST be FIRE RATED
"flame and or fire retardant or flame and fire resistant."
This is a standard Certification that comes with most canopies.
This could be attached to the canopy (stamped, stitched, printed) or on your carry bag or in the printed documentation that came with the canopy when you purchased it.
Please be sure you have some kind of proof with you at the show that your canopy is fire rated.
All outdoor booths require your own flame retardant tent or canopy.
