What type of support is required for individual mortars larger than 3 inches in diameter?

Individual mortars larger than 3 inches in diameter require individual support to ensure safety and stability during a fireworks display. This requirement stems from the potential risk posed by larger mortars, which can produce more significant force upon ignition and launch. Proper individual support helps maintain the correct angle and positioning of the mortars, reducing the risk of tipping and misfiring, which could lead to hazards for both the audience and the operators.

Support structures can include wooden staves or similar materials that secure the mortars firmly in place, ensuring that they remain stationary throughout the display. This safety measure is essential in adhering to the NFPA 1123 guidelines, which emphasize the importance of controlled handling and operation of fireworks devices, particularly those that have the capability to cause severe injury or property damage if not appropriately secured.
