21 <br /> <br /> <br /> <br />Protection from Hazards Associated with Water Accumulation <br /> <br />A. In open excavations where water has accumulated, the employee must take <br />special precautions. These precautions include the use of a safety harness and an <br />att ended lifeline where the conditions warrant this precaution. The conditions may also <br />require the employee to consider removal of the water, or the application of a shield <br />system to protect from cave - ins.

Employees shall inform all superintendents of any structure which may be <br />undermined by an excavation prior to the excavation operation commencing. If the stability <br />of a structure could be undermined, a support system such as shoring, bracing, or <br />underpinning shall be provided. A Competent Person shall assure that the bracing, shoring, <br />or underpinning complies with OSHA standards. <br /> <br />B.
