Hi Guys, i'm just after some hints and tips on firing cakes and candles from a rooftop in a city centre,

anyone care to share there best practises?

Prepare an exit! (or wear a parachute!)

Work at Height regs may suggest a work positioning harness and lanyard are appropriate. Assume that the wind will be much greater than at ground level don't leave ANYTHING that could blow off the top!

I know its american, but all roofs are the same arent they?

i MUST add this is a show comprising of 3 cakes and 9 candles.... not a huge thing...
just wanted to know if theres any pitfalls etc..

Just make sure that the fireworks are secure and cannot fall, and that you are safe cannot fall but can get out!

I would place the candles in buckets of sand,place the cakes on thick board and secure with duct tape etc,and make sure you have a couple of buckets of water ready,just in case the cakes catch fire after fireing.

What no one has mentioned is fallout...

Should not be much of an issue with the size of event you plan, but with big events, must be a major headache (literally!)

If one side or the other of your building has an area free of people, angle your material so that debris will fall that way (unless your roof is so big that the debris will be contained by it).

What is the roof made of? If it's asphalt sheet that is basically tar and will burn very well.

Plenty of fire extinguishers on hand and people who know how to use them. Ideally the whole roof should be covered in a layer of sand so hot fallout can't start a fire.

Inform the fire brigade that you are doing this so if they get a call that the roof is on fire, they know people are likely to be on it. Also damp down with a hose afterwards even if all looks ok.

I must admit Phill,
i did not mention this as i thought it was basic common sense and the first thing you would consider.

Fallout is something that people do not always take into consideration. It's amazing just how much junk can rain down.

I believe most 'stadium' type events now use 'zero fallout material'. Also used in stage pyro.
