FRA in collaboration with Custom Spray Solutions developed a custom nozzle apparatus that can be used for confined space applications. In particular the nozzle was developed to help first responders address underground electrical fires (vaults, manholes, etc.) in a safe manner. The device allows first responders to set up the apparatus and “walk away”. The device is electrically non-conductive and allows for the safe dispersion of suppression agent in high voltage areas. The nozzle can also be used effectively in a variety of confined space applications. The nozzle is currently being deployed on fire trucks in one of the largest US cities.
