hand expose zone definition
hand expose zone means the strip of land on each side of the locate marks for an underground facility other than a high-pressure pipeline, or 5 metres wide on each side of the locate marks for a high-pressure pipeline as defined by the Alberta Occupational Health and Safety Act. The Hand Expose Zone can be wider than noted for low or intermediate pressure pipeline systems and for other underground infrastructure, and, in those instances where the Owner/Operator requires caution around the underground facility, the Owner/Operator will have that information noted on the locate ticket.
