23 22 SHEQ Monitoring Vibration A study has been conducted on our Dwr Cymru Welsh Water contract to capture robust data to support vibration risk assessments. Ten jetting operators took part in the study which covered the use of various plant including: • Van packs (high pressure jetting machines) • City Flex (for jetting and suction tasks in densely populated areas) • Combination unit tanker (specialising in removing silt, liquid waste and debris) MUS SHEQ Advisor Ben Bamber explains: “Determining vibration levels during high pressure water jetting activities is a priority. Various factors can affect vibration from jetting equipment including the use of the jetting nozzle, the pressure the machine is operating at, and the equipment for the work being undertaken. In add
