Wind is the first thing to plan for. An arch or a column is a sail, and a gust will move a structure that felt solid while you were building it. Outdoor installations need weighted bases, ground stakes or sandbags rather than decorative weights, and anything near a walkway must be secured so it cannot fall onto guests.
Heat and sun are the second factor, and in Dubai they set the schedule. Latex oxidises and bursts quickly in direct sun, so outdoor sets are built from foil and bubble where possible, inflated slightly under full size to allow for expansion, placed in shade, and installed close to the start of the event rather than hours before.
The remaining points are about surroundings and aftermath. Keep balloons well away from overhead power lines, barbecues, fire pits, candles and anything with a flame, since a burst near an open fire is not a small event. Never stage a release: balloons come down as litter that harms marine life and animals, and many venues prohibit it outright. Collect every fragment, ribbon and clip when the event ends.
- Anchor structures with weighted bases, sandbags or ground stakes
- Prefer foil and bubble outdoors, and underinflate slightly for heat
- Keep clear of power lines, open flames, barbecues and candles
- Never release balloons into the sky, on land or over water
- Collect all fragments, ribbons and clips before leaving the site
