Abstract: A nozzle arrangement for use in expelling pressurized fluid includes a dead man control. The dead man control has a manually operable control part movable between a non-operating position, which prevents operation of the nozzle arrangement, and an operating position, and biased towards the non-operating position. The manually operable control part is pivotably coupled relative to a nozzle holder of the nozzle arrangement, which extends away from the pivotal coupling substantially towards a distal end of a nozzle part of the nozzle arrangement. The manually operable control part includes a handle part which in the operating position is substantially against and aligned with the nozzle part.
