Air Burst Clearances
Air Bursts come in two types
- a bright flash and a sharp bang
- a bright flash, a sharp bang and a shower of sparks.
They are suspended on their firing wires, and may drop cold pieces of thin plastic film below them. Lead lengths are supplied to order, in a choice of 1.5 metres, 2 metres, 3 metres and 5 metres.
Look at the table of clearance distances below. Do not compromise these distances, as if there is any problem, it is high in the air above you and is not easy to access with fire extinguishers.
We can supply high-powered water jets which can reach up to 15 metres high.
If a large number are required, then we suggest using our terminal box on the lighting rig so that large numbers of wires do not have to be run up to the grid.

Please call us if you are pressured for space and need to modify these distances. Depending on circumstances such as the lighting equipment, the nature of the walls, the costumes of the performers, these distances can be reduced.
For instance- as the sparks from airbursts are not particularly hot, and if performers had hats, relatively fireproof clothing and no bare skin, distances could be reduced to three metres provided the performers had rehearsal experience with these.
PLEASE NOTE Distances can only be altered after consultation with us as manufacturers.
