Firefighter loses control of hose and knocks pedestrian down
We believe this happened in Russia, a firefighter lost control of a hose when a sudden water pressure surge knocked it out of his hands.
The hose he was using started to thrash around. A woman walking along the sidewalk near the fire tried to avoid the flailing hose, but it actually hits her feet causing her to fall down. You can watch the CCTV footage at the link below.
