Training on forward lays with five inch hose: hose clamp was placed on the five inch line, the hydrant was charged, the line broken and connected to the inlet on the pumper. As the Hebert Hose Clamp was opened, the clamp was rapidly pushed along the five inch hose until it hit the next coupling. The firefighter opening the clamp found it to be difficult to unscrew because of the hose pressure on the clamp and was surprised at how quick the clamp moved when the water flowed through the hose.

LESSONS LEARNED:
1.The new rubber supply hose may have been a contributing factor to the sliding of the hose clamp. 

2.There is a potential for an injury caused by the moving clamp if people are not paying attention. The clamp was placed about eight feet from the coupling before the line was charged. Has anyone else had this problem? We were fortunate that there was another section of hose leading to the inlet, otherwise, the clamp would have ended up against the pump connection. 

3.The time it takes to unscrew the clamp actually increased the time it took for the forward lay to be completed. This evolution was with four firefighters(the engineer, the hydrant man and two were manning an attack line). 

4.The hose clamp will not be used for a forward lay with the five inch supply line.
