What is the purpose of a spray curtain nozzle beneath an elevating platform?

The purpose of a spray curtain nozzle beneath an elevating platform is to protect the platform from fire. When an aerial apparatus is positioned for operations, especially near structures involved in a fire, the risk of the platform and its components being exposed to extreme heat and flames is significant. The spray curtain nozzle directs a curtain of water around the apparatus, effectively creating a barrier that cools the surrounding area and reduces the thermal radiation that can damage the platform and potentially affect its operational capabilities. This water curtain acts as an essential safety feature, ensuring that the integrity and functionality of the platform are maintained while allowing firefighters to perform their tasks from an elevated position.

This function is critical in ensuring the longevity and reliability of the aerial apparatus during firefighting operations. In contrast, while protecting firefighters and surrounding exposures is important, the specific role of the spray curtain nozzle is aimed primarily at safeguarding the aerial platform itself.
