When placing launch pads for pyrotechnic displays, what critical factor must be considered?

When placing launch pads for pyrotechnic displays, prevailing wind direction and strength is a critical factor to consider because it directly influences the safety of both the audience and the surrounding environment. Understanding the wind conditions helps in determining the trajectory of the fireworks and ensures that any fallout or debris from the pyrotechnic display is directed away from populated areas, flammable structures, and other hazards. This assessment minimizes risks associated with fire and injury, making it essential for planners to take thorough wind assessments into account before proceeding with setup.

While other factors like local wildlife habitats, expected attendance numbers, and availability of fire suppression materials are also important in the broader context of safety and regulations, they do not have as immediate and direct an impact on the operational safety of the pyrotechnic display itself as the prevailing wind does.
