The feedback I received from our operators was disappointing. I'm told the material was focused on directional digging and line locating rather than actual hydro-vac safety. They found it not relevant to our work type at all which is trenching/locating pipes, exposing line breaks/water valves/utility pole installations. I would like to take it myself to see first hand but I would like to see it review the safety of working with high-pressure water and/or air, vacuum system safety, overhead safety for tank/boom, traffic/noise, trenching/unstable ground to name a few
