I have insurance but i am constantly worrying when doing a job were someone could trip over my hose,are you covered if you have warning signs etc,are the mats to cover you hoses a good thing,all i was doing at a job recently was stopping to warn people to watch they don`t trip,you always get an ambulance chaser.i only work out of van you see and if the customer doesn`t have a driveway i have to trail my hose across pavement and i know i am taking a chance,has anyone been sued?
