Abstract: A flexible cleaning lance safety apparatus is described as including a tripod support structure located close to an opening into an object to be cleaned. A flexible lance drive is fastened to the support structure for driving a high pressure fluid through a lance to the object to be cleaned. A snout tube is connected between the lance drive and an opening into the object to be cleaned. One or more micro pressure valves on each leg of the tripod support structure is operative to sense a predetermined force applied between the support structure and a support surface supporting the tripod support structure. When the predetermined force is sensed this causes the high pressure fluid to be diverted from the lance and the object to be cleaned to atmosphere.
