Hose handling system and methods of use
Abstract Embodiments of the present invention include a hose handling system having a hose guide plumbed via a wash line to a fluid delivery device. The hose guide includes a pulley installed on a frame member, and a spray nozzle adapted to dispense a wash mixture. The hose guide is adapted to guide a hose as the hose is inserted into or withdrawn from a manhole, with the hose traversing the pulley. The wash mixture can be delivered through a wash line to the hose guide, which sprays the wash mixture on the hose in order to reduce or eliminate gross contamination or microbial contamination on the hose. The wash mixture typically, but not necessarily, has a freezing point below 32F and includes: a quaternary ammonium compound, an alcohol or glycol, an alcohol ethoxylate, and a fragrance. 9489776_1 COj cooL co (Ol
