What is the minimum thickness requirement for the walls and roof of a manned floating vessel platform?

The minimum thickness requirement for the walls and roof of a manned floating vessel platform is set to ensure structural integrity and safety during fireworks displays. A thickness of 3/4 inch is deemed sufficient to withstand the potential stresses and forces that may be encountered during such operations, including wind loads and the impact of fireworks firing. This specification is critical in maintaining the stability and protection of personnel on the platform, as comprehensive safety measures are central to NFPA 1123 standards.

Choosing a thickness less than 3/4 inch could compromise the safety of the structure, whereas a greater thickness may not be necessary for the intended use, leading to unnecessary material costs without added benefits. Therefore, 3/4 inch effectively balances safety and practicality for the floating vessel platform in the context of fireworks displays.
